About Me

Software engineer with 4+ years shipping production systems around markets. The work runs from exchange APIs and risk dashboards to SSR product sites.

I own the path end to end: schema and API, background jobs, authentication, and the React interface a person actually uses.

Nine shipped systems, including Trading Suite, QuantAI Traders, a Polymarket terminal, NexEdge, staking apps on EVM and Solana, and the bilingual Owjen site.

Based in Dubai. Open to software engineering roles in fintech and trading infrastructure.

TRADING SUITE

One risk view across accounts

5pages
4venues
WebSocketsync
Problem
Fills and open risk lived in separate Hyperliquid and MetaTrader logs, so total exposure was not in one place.
Architecture
An Express API routes each symbol to the right venue. Sigma and correlation use 60 daily closes. Positions and the trade log persist on the server and broadcast over WebSocket.
Shipped
Overview, positions, trade log, APT/ICAPM, model parameters, and CSV import. A refresh keeps the same book.
