Most recently, my work focuses on fractional executive leadership, cloud data architectures, and applied AI innovation. This includes serving as hands-on CTO for a Dallas-based AI services startup (Eam.ai), Fractional CTO for a Northeast multi-family wealth office, Technical PMO for a major academic medical center's cybersecurity organization, and a senior pre-sales advisor and partnership tax subject matter expert.
I am the Founder and CTO of MTech6.net, an independent technology consulting and executive advisory firm. At my core, I am a results-oriented leader who values people, mentorship, and elegant, simple solutions to complex technical challenges. With over 20 years of experience as an engineer, architect, and technology executive, I bridge high-level corporate strategy with modern, hands-on execution. Above all, I am a dedicated husband and father.
My career began on Wall Street as a C++ developer for Salomon Brothers’ collateral allocation trading desk in Florida, followed by key software engineering roles across New York financial institutions, including Smith Barney, DLJ, JP Morgan, and Merrill Lynch.
Embracing the evolution of C# and .NET enterprise frameworks, I relocated to Dallas, Texas, in 2006 to join a $30B asset management hedge fund, where I eventually rose to Head of Software Development. Following a senior technology role at Wells Fargo Securities in Charlotte, North Carolina, I returned to Dallas to lead high-scale SaaS engineering organizations, practice operations, and global platform teams for Big 4 leaders, including Deloitte Tax and PwC.
An MS in Computer Science from the OMSCS program at Georgia Tech with a specialization in Artificial Intelligence and an Electrical Engineering degree from Swarthmore College. Hands-on technology leader, architect, and coach.
At a global technology services and tax partnership system development firm, I served as FTE Senior VP for partnership tax implementation platforms and pre-sales engineering work.
I led technical discovery and cloud security architecture at a global cybersecurity MSSP, embedding Zero Trust controls, Microsoft Entra ID, and executive health visibility for C-level stakeholders (CEO, CTO, CISO).
At a multi-family office in the northeast, I realigned the IT and engineering organization to eliminate reactive delivery, establishing sprint discipline, Level 1 support automation, and firmwide Responsible AI and Security Policies.
Led the technology effort for an AI consulting start-up firm as a hands-on CTO, designing, coding, and setting up our Azure cloud infrastructure for an MVP that uses LLM Large Language Models and OpenAI technology for a proprietary platform.
Worked with several LLMs or Large Language Models across OpenAI and Azure AI Studio (now Azure Foundry), leveraged AI models as thought partners to expand the diversity of thought. It is what Ray Dalio, founder of Bridgewater Associates coined "Triangulation."
As a technology leader in our CATT (Center for Advanced Tax Technology) Tax practice, I am overseeing the architecture and design of our partnership tax, family office services, and other tax services offered by RSM. With the launch of PartnerSight, we are positioned to dominate the tax technology digital landscape.
When I first heard there was a volunteer opportunity available that would help me meet my newest colleagues at RSM but also give me the opportunity to help families in need, I jumped at the chance. My first year at RSM Dallas I had the opportunity to participate at a Volunteer Event at the Perot Museum with a great organization here in Dallas called Family Gateway. I thoroughly enjoyed an educational and fun day with the kids and families at the Perot Museum of Nature and Science in Dallas.
Tax technology leader in our Parternship Solutions Group (PSG) tax practice. I built a global, first of its kind Automatic and Exchange of Information system to gather investor account information and prepare FATCA and CRS compliance reports for our clients. This was my first time implementing an SAP HANA Big Data Solution. I remember another great mentor at Deloitte Partner Andrea Smith, when I told her I never used SAP HANA, she said: that's okay, Helder, I know you can do it.
During the summer of 2019, while visiting our India office in Hyderabad, I had the unique opportunity to address the graduating class of engineers and computer scientists at a local university. I was impresessed by the almost equal distribution of male and female candidates, unlike my days studying engineering. It is something I took back to Deloitte and encouraged the hiring and career building of our female tax and technology professionals.
Director of tax technology at PwC Dallas. I led a global team of full-time US developers, off-shore resources, and vendors to deliver a global Country by Country or CBCR reporting system. It was 60 resources across the globe coordinated to deploy 3 new integrated tax products. We delivered on time and under budget to three different data centers around the globe.
While at PwC, a great mentor of mine, our tax practice leader and Partner Andrew Nardo said to me: Helder, I want you to personally know everyone in our practice. And I took that to heart. I made a point of talking and connecting with everyone in our tax practice no matter what level or tenure they were, all 150+ of them. It is something I have taken with me since.
Completed a Master's degree online with Georgia Tech, with a concentration in Artificial Intelligence. The program was the Online Master of Science Computer Science (OMS CS)
I never expected to go back to school this late in my career, but my experience with Udacity and Stanford's online Data Science Program piqued my curiosity in academia, but most importantly I wanted to be able to teach at the undergraduate level someday.
Senior Thesis project included construction and assembly, including sweating copper pipes, plumbing, wiring, and “C++“ automation of the Swarthmore College solar lab atop Hicks Hall Engineering building. The program included controlling valves and reading thermistor sensors to gather data and carry out experiments.
Professor Arthur McGarity was my faculty advisor and started my passion for programming, at the time “C++“ was a relatively new language and modern graphical user interfaces were also not yet common. Professor Frederick L. Orthlieb or “FLO“ as he was affectionately known, really taught me how to swing a hammer and sweat copper pipe. He was a great teacher and wonderful mentor, someone who positively influenced my career and my life.
Under an NSF grant, I worked on the System-4000 Upgrade of the Swarthmore College Materials lab. Professor Faruq M. A. Siddiqui, Professor Frederick L. Orthlieb, and myself were later published in the ASEE Annual Conference Proceedings, 1992.
This was a wonderful summer for me. Although I can remember having to go back to my dorm and showering just to cool down because re-roofing work was being done atop the Hicks Engineering building that summer, it was a rewarding and prolific experience and I am very grateful for that grant and time spent.
Studied the physics and logical design of computers including microprocessors, CPU design, RISC and CISC, caching, virtual memory, assembly and machine language, and multiprocessors. Lab work also included analysis via simulation and microprocessor design using CAD tools.
What I enjoyed most about this class was not just learning “C“ to code a microprocessor simulator but that our instructor was a visiting professor from the industry, someone who had hands-on work experience building microprocessor chips.
A high-impact framework of technical architecture, executive leadership, and delivery excellence.
First impressions drive conversion and user engagement. I lead architecture & delivery of modern, responsive web portals & user interfaces that balance intuitive user experience (UX) with enterprise-grade performance; delivering polished, client-facing digital doors on time & on budget.
Accelerating time-to-market begins with bridging business strategy and technical execution. Utilizing Domain-Driven Design (DDD) and Agile methodologies, I establish clear domain models and ubiquitous languages that unite non-technical stakeholders and engineering teams across the entire product lifecycle.
Quality and security must be engineered from day one. I instill software craftsmanship standards across .NET engineering organizations—nourishing Test-Driven Development (TDD), SOLID principles, and enterprise design patterns to build maintainable, high-throughput applications with low defect escape rates.
High-performing engineering cultures are built through continuous learning and clear career paths. I design and lead interactive training programs covering Domain-Driven Design, DevSecOps practices, AI adoption, & domain-specific financial capabilities to level up global engineering teams.
Resiliency requires embedding security directly into the software pipeline. Partnering closely with CISOs and risk teams, I implement Secure Software Development Lifecycle (SSDLC) frameworks, automated SAST/DAST testing, Zero Trust access controls, & Incident Response Playbooks that protect org IP & data assets.
Data platforms must scale with business growth while enforcing absolute privacy and compliance. I architect multi-tenant data warehouses & data lakehouses on the cloud—incorporating data catalogs, strict lineage, and metadata dictionaries to ensure peak query performance, 99.99% uptime, and regulatory readiness.
Outside of the always helpful Gang of Four book, Enterprise Design Patterns by Martin Fowler and the SOLID principles introduced by Robert Martin have been a guiding principle.
How I work with your organization to deliver enterprise class digital products.
I blogged my experience in working through the Udacity Data Scientist Nanodegree online program.
As part of the udacity.com Data Scientist nanodegree, this is the final project of the program, otherwise known as our Capstone Project. It involves building a stock price predictor using machine learning that takes daily trading data over a certain date range as input, and outputs projected closing price estimates for given stock and query dates. Showcasing type ahead search and ML.

Recommendation Engines are the algorithms used to make suggestions or recommend things to you based on past purchases or usage, or based on what other users are downloading. Apps like Netflix have algorithms in place to suggest movies you might also enjoy based on what you have been streaming or what is most popular.

Following a disaster, there are millions of tweets, news alerts, or social media and online messages that are generated. During this critical time, organizations are overwhelmed with data and they need to filter out what is pertinent information from what is just noise. Using NLP and ML this project delivers a web portal to process given messages.

Recommendations I have received over the years from my colleagues.
I had the pleasure to work with Helder during our time together at Wells Fargo. Helder was a very dedicated and focused leader on the team. He worked to establish strong relationships with the numerous traders and was very knowledgable about the products and markets they traded. He was also very solution focused and worked hard to deliver technology that significantly improved their ability to manage risk and support clients.
Very strong leader, communicator, problem solver, and team player. Our organization at the time was 200 + people and I could imagine he was working on 20 + active projects but he always went the extra mile for my projects. His diverse background was very helpful as we transitioned order management systems.
I managed Helder at an early time in his career. It became instantly apparent that he was an excellent technician and he possessed the skills needed to progress in our industry. Reconnecting with Helder now leads me to the conclusion that my early estimation was correct.
Smart, energetic, dedicated employee; strong technical skills and great leadership talent; solid industry knowledge and effective business communicator; highly recommended.
Helder is a wonderful leader. He inspires the team and always has a positive attitude. I thoroughly enjoy working with Helder and know if I ever have any questions or concerns, he is right there to assist. He is extremely knowledgeable in data analytics and SQL and I would advise anyone who has the opportunity to work with him, to trust Helder as you are in good hands with him.
I worked with Helder in Verizon. Helder is very strong technically. Whenever I was stuck with a technical issue or a business issue Helder was always there to help and give advice. I regard Helder as one of the strongest technical leads I have known. I highly recommend Helder for any position and he is capable of steering any complex project and bring traction to the project. He has proven that repeatedly in Verizon.
I had the pleasure of working with Helder while at RSM. I admire his leadership and coaching style. Helder leads by example and is someone who invests in the success of others. We worked closely to plan out activities focusing on sharing knowledge across our team about various cutting-edge technology trends. Helder understands complex issues in technology and offers great insights from his experience.
I had the pleasure of working with Helder on a few projects at RSM related to our data science digital upskilling and community. He is such a genuine and collaborative individual and was always willing to step up as a senior member of our data science community to coach and mentor our junior technologists. During the RSM Data Mining Competition we always had fun giving each other a hard time about which team was going to take the top spot in the competition and then would jump on calls to give brief demo's or instruction on our methodologies. He is a great addition to any technical team looking for a leader who will take the time to coach and mentor others.
I had the privilege to work with Helder as part of the Tax Tech group at PwC. He not only was a talented technology professionals but also a kind and caring team member. As lead for the data team, Helder successfully managed several complex projects while taking the time to coach and mentor his team in a positive and future focus manner. He would always offer help to those in need and supported his leaders, peers, and team in a collaborative way. Helder will be an asset to any organization through his dedication and technical expertise.
Helder was an exceptional mentor, he leads by example and is both inspiring and motivating. He is a hard-working and skillful leader that enjoys teaching others. I had the pleasure working with Helder on several projects, benefiting from his leadership. He always went out of his way to help me learn the fundamentals to successfully complete the projects. He brought new ideas during our collaboration and created an enjoyable environment, helping me grow. I look forward to the opportunity to work with him again, his level of experience and willingness to share will bring value to any organization.
