What I'm looking for

I seek backend or platform roles in fintech-focused teams where I can architect scalable payment systems, improve reliability, mentor engineers, and drive measurable operational improvements.

I am a backend engineer with over five years of experience building scalable payment, wallet, and peer-to-peer systems in fintech environments.

I have led design and implementation of high-availability microservices and event-driven platforms, improving transaction throughput, reducing latency, and driving reliability across production systems.

My achievements include increasing peer-to-peer friend limits while maintaining data consistency, migrating 160M customer records smoothly, reducing MySQL CPU usage from 98% to 20%, and cutting system error rates from 10% to 1%.

I mentor junior engineers, create operational runbooks, coordinate cross-team integrations, and focus on observability, performance tuning, and safe financial reconciliation.
