What I'm looking for

I’m looking for a backend-focused role where I can own high-impact services, improve reliability and performance, and collaborate closely—while bringing leadership through mentoring and engineering process improvements.

I’m a software engineer focused on building scalable backend services with clean service boundaries, maintainable APIs, reliable data modeling, and dependable handling of high-volume financial transactions. In my current work, I’ve helped implement stakeholder-driven approval workflows for business transfers and strengthened governance with role-based access control, permissions, spending limits, and audit trails.

Previously, I designed and implemented a fraud detection system using advanced rule-based algorithms, transaction monitoring, and pattern recognition—reducing fraud detection time from 4 days to 30 minutes. I also built memory-efficient reporting services (cutting peak memory usage by 90% while serving 10,000+ reports monthly) and high-performance data aggregation across 200,000+ businesses, improving retrieval time from one week to 6 hours.

I’ve led backend feature delivery and platform reliability as well—automating cryptocurrency listing workflows (integration from 3 days to 3 hours), transforming bottleneck services into highly available systems through performance tuning and caching, and maintaining uninterrupted uptime through continuous monitoring. I enjoy technical leadership, mentoring, and improving engineering processes, and I’ve also worked on monitoring stacks (Prometheus/Grafana/Sentry), API documentation (Swagger), and database migrations between MongoDB and PostgreSQL.
