Who am I?

I’m DEV91, a full-stack developer and MT4 / MT5 algorithmic trading specialist. I work across two disciplines that most developers never touch together — building production-grade web platforms and automated trading systems that run around the clock.

I build web apps end-to-end with PHP / Laravel, React / Next.js, Node.js, and MySQL / PostgreSQL, and I write MQL4 and MQL5 expert advisors, custom indicators, and risk management systems for MetaTrader. Every engagement is remote, contract-based, and starts with a clear scope.
