Software engineer building AI/ML systems in production. I integrate intelligent features into existing products, modernize legacy codebases, and prototype fast.

AI Integration$100–150/hr

Your product doesn't have AI features yet. I make that happen. Search, classification, recommendations, LLM-powered tooling, data pipelines — taken from concept through production deployment. This has been my full-time work for the past four years.

Legacy Modernization & Security$75–120/hr

Your codebase is a liability and nobody wants to touch it. Outdated dependencies, degraded performance, security audit failures, spaghetti architecture. I inherit the mess, fix what's urgent, and leave it maintainable. I've spent roughly a decade cleaning up systems like this, and I'm comfortable in whatever your stack is.

Rapid Prototypingfixed price

Working MVPs in 1–2 weeks. Not wireframes or slide decks — functional software your team can test with real users. Defined scope, fixed price, fast turnaround.

Available for part-time contract work

10–15 hours/week through my LLC. I take on focused engagements where the deliverable is clear and I can move fast. Based in Virginia.
