What I'm looking for

I’m looking to join a team where I can design and ship production LLM systems end to end—prioritizing reliability, evaluation, and automation—while building secure, data-driven trading or AI product features.

I’m an AI Engineer with 6+ years building software and 3+ years delivering AI and trading systems for international clients. I design and ship production LLM systems end to end, including multi-agent pipelines, RAG, and automation, with a strong quantitative foundation in probability, statistics, and Monte Carlo simulation.

I’m the Founder and AI Engineer behind AlgoCustom, an AI platform that turns natural-language strategies into backtested MetaTrader 5 trading bots. I built a multi-agent LLM pipeline with model routing by task difficulty, and a RAG system over a knowledge base mined from years of client work.

I also deliver AI-first trading solutions as a freelance developer, including production Expert Advisors (MQL4/MQL5) and TradingView indicators (Pine Script). From Telegram-to-MetaTrader 5 automation to a Python-to-MetaTrader bridge with low-latency structured logging, I focus on reliability, evaluation, and security—like identifying and fixing an API-key exfiltration vulnerability in an agent sandbox.
