What I'm looking for

I’m looking for a role where I can own backend architecture for high-throughput systems—driving async/event-driven design, performance optimization, and observability—while mentoring engineers and delivering measurable business impact.

I’m a Senior Backend Engineer with 9+ years of experience designing and delivering high-load distributed systems in Web3, FinTech, AI, and automation. I build backend systems from scratch to production, designing financial transaction flows and async & event-driven architectures while focusing on performance optimization, production monitoring, and business metrics tracking.

In my recent work as an independent contractor, I’ve owned the full lifecycle—architecture, implementation, deployment, monitoring, and scaling—and mentored junior engineers through code reviews and architecture guidance. I delivered revenue-generating platforms (up to 4,000+ users and $200k+ revenue), including a multi-chain crypto wallet & payment gateway, an AI gateway platform with billing and usage metering, and automation/CRM products with task scheduling and strong data consistency.
