I take on a wide range of projects, from a script that scrapes and cleans a stubborn data source to a full service running in production. Most of that decade was spent at 3 large companies and 5+ startups, largely in FinTech and PropTech. Those industries are unforgiving about correctness: a transaction can't be off by a cent, a property record can't be silently wrong. That standard is what I bring to every project regardless of the domain — including the small ones. What I do well: - Backend services, APIs, and integrations with third-party systems - Data pipelines, ETL, warehousing, and turning messy real-world data into something reliable - Automation and internal tooling that removes manual work - Debugging and rescuing projects that someone else left in a difficult state AI/LLM sounds redundant, but I am literally evolving alongside these technologies. less -

I'm a New York City–based software engineer with more than 30 years of building software that actually ships.

I work across the full stack, from backend architecture and APIs to the front end, so you don't have to hire three people to get one project done. Most of my time these days goes to AI work: LLM integrations, automation, and features that move the needle for a business instead of just sounding good in a pitch deck. I also do a lot of Shopify, including custom themes, private apps, API integrations, and cleaning up stores that have outgrown their original setup. I'm a native English speaker on US Eastern time, so you get straight answers, fast turnarounds, and no back-and-forth trying to figure out what I meant. Tell me what you're trying to build and I'll give you an honest read on whether I'm the right fit and what it'll take. less -
