What I'm looking for

I'm open to remote work building reliable backend systems for fintech, payments, trading, or systems integration, with a focus on correctness, fault tolerance, and production stability.

I've built high-reliability fintech systems at EndoTech, including a full FIX integration for order execution and lifecycle tracking, plus NestJS and RabbitMQ pipelines for trading signals. I maintained monitored production uptime with zero unplanned downtime incidents throughout the engagement.

Across independent fintech, e-commerce, IoT, and telecom work, I've integrated seven-plus payment gateways, built reconciliation and fund-transfer workflows, and delivered trading platforms, pricing engines, APIs, and cloud-connected automation systems. My work centers on Node.js, PostgreSQL, event-driven architecture, and production stability where errors directly affect money movement.
