I build backend and full-stack systems end to end. About 20 years in software: 10+ of them enterprise Java, and the last year building crypto trading systems in Rust and Python.

Over the past year I built two trading systems end to end: a bot that trades price gaps across five crypto exchanges at once, with every exchange integration written by hand, and a system on Binance futures that comes with its own engine for testing strategies against years of market data and searching for the settings that hold up - it has evaluated 17.3 billion parameter combinations and runs about 100x faster than the fastest off-the-shelf framework I compared it against. Alongside them, research across US stocks and crypto on how much of a strategy's result is real and how much is luck.

Before crypto I built Maress, a platform that helps shipping fleets cut fuel use and emissions, from scratch in Java and Spring Boot on PostgreSQL; it reached a Fortune 500 client and was acquired. I ran my own software company for nine years, leading engineering across around 80 projects while staying in the code, and spent seven years on enterprise Java at EPAM for Sony, Lufthansa and Bank of America.

Looking for a senior backend or full-stack role, remote. Rust, Python, Java, TypeScript and React, PostgreSQL.
