Software Executive and Entrepreneur

As a proven software executive and entrepreneur, my passion is building and inspiring impactful organizations and technology around a clear vision. As CTO and cofounder of GovSpend, I was instrumental in the company’s growth from a concept to a 9 figure private equity exit doing acquisitions of its own. In my early career, I earned my bachelor's degree at 17 years old and master's degree in creative AI soon after. I’ve spent nearly 20 years leading initiatives for both major organizations and early stage startups.

My approach is to bring a strong entrepreneurial spirit and inspiring vision for the future to my teams. I believe in leading by example and staying connected to the technology. It’s not unusual for me to jump from board meetings to 1-1s with my team leads to implementing a feature in the codebase all in the same day. Advocating for my team members is one of my core values, and I build relationships fostering loyalty that transcends the workplace - evidenced by above average tenure in an industry known for high turnover. I shine when given an impossibly hard problem and never back away from a challenge. My superpower is quickly delivering solutions and products that are inspired and reusable - but most of all, unlocking real customer and shareholder value.

Chief Technology Officer & Cofounder, GovSpend (aka SmartProcure) 2011 - 2024

Role
As CTO and Cofounder of GovSpend (also known as SmartProcure), I was instrumental in our growth from a concept to a 9 figure private equity exit doing acquisitions of its own - managing 9 divisions. I set the product and tech roadmap and architected most projects. I built our initial tech and remained a top contributor even as we matured. I was critical to our M&A activity - during evaluation, due diligence, and integration strategy. I grew developers from junior to senior and from ICs to team leads and directors. Our customers use our search and analytics platform to dramatically grow their public sector businesses.
Tech
  1. We built best-in-class, industry-leading technology with real time search and analytics on billions of records. It’s powered by Contexture, my open source toolkit with an advanced query editor, pivot table, in memory joins, and semantic (vector) search - but above all, a relentless focus on performance and user experience. It can ease users from a simple search box to one of the world’s fastest BI tools.
  2. We built thousands of web scrapers, a custom DSL with tens of thousands of extraction strategies, tons of backend jobs pulling API data, and an engine to automate tens of thousands of recurring public records requests. All with deep auditing and real time change notifications.
  3. We used state of the art AI models for classification, transcription, summarization, prediction, and so much more. Production AI at scale over billions of records is a unique challenge, so we used commercial foundation models, fine tuned, and even trained our own (BERT transformers).
  4. We built a fullstack web app using modern javascript and typescript in nodejs with feathers on the backend, react with chakra and mobx on the frontend, socket.io for realtime events, temporal.io for background jobs, and data in the latest verstions of elasticsearch, mongo, redis, and cratedb. Some file parsing logic was written in c#. Scrapers were written using python, typescript, and mozenda.
Culture
I built a relaxed but high-performance culture - a startup with a dose of stability and bigger tech process. You need a reason for tech to be closed source - not permission to be open! Our open source code has over 10 million downloads. I created hackathons with one rule - you're not allowed to do your normal work. Besides peer review, we built a bot to automate best practices. Functional programming is big and we built futil, endorsed by lodash on their homepage. Our tech stack is kept up to date, and we're always exploring new tech. It’s tech nirvana. beforeyouapply.com/group/engineering-at-govspend
Mission
GovSpend provides public sector intelligence. It’s incredibly helpful for government. But if you’re a government contractor, it’s legal corporate espionage - who your competitors are, what they’re charging, and who’s signing the deals. It can tell you if competitors are entering new markets or if customers are buying products you sell from someone else. And the newest addition uses AI models to generate transcripts of public meetings - to tell you, for example, when anyone in the country mentions something at a local council meeting. Those same AI models will make predictions and forecast upcoming spending.
Impact
We did incredible things at GovSpend and can really say we made the world better than we found it. We made a dent in the universe. We disrupted and improved government procurement. And at the start of the pandemic, we helped government to help a world in free fall. We had a real social impact. But most of all, we built an incredible team of world-class engineers and the most talented people I’ve ever met.
