Let's ship something real
I'm Tom — an AI product engineer with 15+ years building and scaling web platforms, including six years leading engineering at a live-video SaaS through 10x growth. Now independent via mxmn.net, I take products end to end: architecture, delivery, and the product decisions in between.
// what i can do for you
Full-stack product engineering
Features shipped end-to-end — from database schema to API to pixel. TypeScript, React, Node, and the judgment to know what not to build.
AI features & agents
LLM-powered product features, agentic workflows, RAG pipelines, and the unglamorous eval work that makes them actually reliable.
Technical advisory
Architecture reviews, stack decisions, hiring support, and a second pair of eyes on the hard problems — without the full-time price tag.
Team augmentation
A senior engineer embedded in your team — part-time or full-time — who ships from week one and raises the bar as he goes.
// receipts
of order-status tickets resolved end-to-end with no human in the loop
agentic AI support pipeline, ~2,100 conversations/month
reduction in support cost per conversation ($1.00 → $0.05)
replacing a vendor agent with a custom LLM pipeline
scaling of concurrent live users (1,000 → 10,000 per event)
monolith → microservices at crowdcast during covid
live viewers per month kept reliable with a five-person team
thousands of events on a production live-video platform
// selected projects
Maxi.io
AI life coachSolo build from zero to production: LLM integration, user management, Stripe payments, and native iOS & Android apps via React Native and Expo.
Picofolio
portfolio tracker & trading journalLocal-first tracker for Interactive Brokers investors: portfolio deltas, a tagged trading journal with realized P&L, and a daily P&L calendar. All data stays on your machine.

// how engagements work
Intro call
A short, no-pitch conversation about what you are building and where it hurts.
Scoping
We define the problem, the shape of the engagement, and what success looks like.
Build & ship
I get to work — async-friendly, communicative, and demoing progress early and often.
Handover
Clean handoff with docs and knowledge transfer. No lock-in, no mystery code.
Engagements range from a few days to a few months — from joining a team as an extra senior engineer to deliver a roadmap piece, to part-time embedding for companies building AI features who want a steady hand on the wheel.
// previously shipped with
Each engagement was different, but the thread is always the same: show up, understand the context, and ship something that genuinely moves the needle.
