I got here the long way.

— My story —

The long way here.

From a GPA under 1.0 to leading engineering on a platform that moves real money. Ten chapters, in order, the way it actually happened.

  1. i.

    1995

    Prince Frederick, Maryland

    I was born in Calvert County, Maryland. My father spent more than 30 years as a network engineer, so I grew up surrounded by computers and was taking them apart long before I understood what was inside. Neither of my parents had a college degree. I would be the first in my home to earn one.

  2. ii.

    2013 to 2016

    The first try

    I graduated from Centennial High School in 2013 and started at Georgia Perimeter College that fall. It did not go well. I failed classes, landed on academic probation, and eventually sat out on academic exclusion with a GPA under 1.0. By most measures, that was where the story should have ended.

  3. iii.

    2013 to 2019

    Learning to work

    So I worked. A car wash. Waiting tables. Personal training on the side, then Life Time Fitness. None of it was software, but all of it was the job: show up on time, read the person in front of you, earn their trust, and take care of them. I still use those skills every day, in every client call and code review.

  4. iv.

    2019

    Going back

    In spring 2019 I landed my first tech job, a software developer role at CWT Industries writing VB.NET, without a degree. It was not the right fit and only lasted two months, but it proved I could get in the door. That summer I finished a data analytics boot camp, and that fall I went back to school, this time married and raising three kids. Within months I was a Systems Operator at Intralot, keeping live lottery servers running around the clock, and a Teaching Assistant in Georgia Tech's coding boot camps.

  5. v.

    2020

    Dean's List

    Spring 2020: a 3.75 term and the Dean's List, from the same student the system had already written off. I joined Blockchain at Georgia State and later became its president, and I started substitute teaching full stack and data science boot camps at Georgia Tech, teaching the material I was still mastering myself.

  6. vi.

    2021 to 2023

    The Mailchimp door

    After two to three years of applying, I earned a Systems Engineering Internship at Mailchimp and rotated through every systems team before landing in core infrastructure. It turned into a full-time offer as a Data Engineer II, which I started in July 2022, before my degree was even conferred. Proof that it could be done.

  7. vii.

    Dec 2022

    The degree

    I finished my Bachelor of Science in Computer Science at Georgia State, three years after walking back in. First-generation graduate, working full time, teaching part time, three kids at home. The odds said no. I did it anyway.

  8. viii.

    2023 to 2026

    Betting on myself

    A senior colleague who left for Coinbase told me to build in blockchain while it was still early. I co-founded Project Pi Labs, raised a $250K seed round, and shipped Pi Pools, a staking protocol that cut the entry minimum in half and served thousands of users. We later spun out Liquid Agent, an AI money app, after a demo on stage in Las Vegas.

  9. ix.

    2025 to now

    Leading engineering

    Today I am Tech Lead at SoonPay, a platform that sends money from the US to families in East Africa. I built the iOS and Android app, the web app, most of the API and the ledger that tracks every dollar, and I keep it running in production.

  10. x.

    Now

    Building my own thing

    Now I build custom software for people with real problems to solve: web apps, APIs, payments, AI agents and the infrastructure under them. Everything from scratch, no templates. If you have an idea, let's build it.

If you want to predict the future, build it.

— Let's build —

Real solutions.
Built from scratch.

Everything I build is custom. No templates, no page builders, no plugin stacks. You tell me the outcome you want, I scope it honestly and quote a fixed price, then hand you the source code, documentation and a working deployment.
