Twenty years of code, ten of them on billion-dollar job sites, and more hats than a haberdasher.

The Story

Hi! My name is Tony. I've also gone by Patrity for many years. I'm a full-stack developer with a passion for problem solving and a love for learning. I've been programming for over 20 years and working professionally for over 10.

I still take on freelance and consulting work, mostly with small businesses that need something custom: customer portals, e-commerce, AI implementations, and whatever unique challenge walks in the door. In 2026 an online presence is table stakes.. the interesting part is what you build on top of it.

From 2022 to 2026 I curated content, edited video, sourced sponsorships, and managed the community for Fireship, one of the biggest programming channels on YouTube. I joined at around a million subscribers and left at four. The role ended when the company was acquired, and it's still one of the best chapters.

By day I'm a project controller and consultant on multi-billion dollar industrial mega-projects: progress, forecasts, budgets, and increasingly the AI agents and data tooling underneath them. That intersection is where most of my interesting problems (and most of the blog) come from.

Career Timeline

2026 — Present

Project Controls SME / Consultant

Next Logical Step Solutions

Project controls SME on one side, AI and automation builder on the other.. bridging the gap between technology and construction for a company focused primarily on large data center builds. The spreadsheet still gets automated before anyone asks.

2025 — Present

AI Implementation

McDermott, Consulting & NLS

AI for practical business applications: custom RAG pipelines, OCR implementations, OpenAI and Anthropic API integrations, and agentic workflows that cut labor cost and clean up data pipelines. Started at McDermott, sharpened through consulting, and now core to the day job at NLS.

2022 — 2026

Content & Community Manager

Fireship

Helped grow one of the biggest programming channels on YouTube from 1M to 4M subscribers: content curation, video editing, sponsorship sourcing, community and social, and eventually scripts and full productions. The role ended when the company was acquired. Still one of the best chapters.

2021 — Present

Freelance Developer & Consultant

TechHive Labs

Freelancing and consulting for small businesses while building my own products: Cognova, TakeoffHelper, Vectly, and more. Full-stack web development, AI implementations, and digital strategy.

2016 — Present

Project Controls Specialist

McDermott, Zachry & More

Small industrial contractors and large EPC firms on mega projects for giants like Exxon, Chevron, Valero, and even SpaceX. The first four years (2016 to 2020) were pure estimating, pricing oil and gas work and learning where every number comes from. After that: progress, forecasts, budgets, and the tools to automate all of it.

2006 — 2016

The Starting Point

Construction Field + Self-Taught Dev

By day (2011–2016), hands-on in civil and survey crews, learning construction from the ground up. By night (2006–2016), teaching myself to code through game development, MMORPGs, and countless side projects. Learned HTTP, relational databases, OOP, and software architecture the hard way: by building things that broke.

What I Actually Do

Three lanes. They overlap more than you'd think.

Construction data

Progress, forecasts, earned value, and the 3D model data underneath it all. Ten years on EPC mega-projects, most of it building the tools the department didn't have yet.

AI agents & inference

RAG pipelines, agentic workflows, and a homelab that hosts most of it. Four 3090s, LiteLLM, and opinions about MoE models.

Web apps that ship

Nuxt and Postgres, plus whatever the job needs. Products of my own and custom builds for small businesses that outgrew the template.
