What I'm looking for

I’m looking for a team where I can build secure, low-latency microservices and APIs, improve observability and performance, and ship end-to-end with modern CI/CD, Kubernetes, and clean architecture.

I’m an experienced full-stack engineer with over 9 years of delivering scalable, high-performance applications across fintech, enterprise, and cloud-native platforms. I specialize in backend development with Node.js (NestJS), Go, and Python (FastAPI, Flask, Django), paired with modern frontend expertise in React and related frameworks.

I’ve repeatedly delivered measurable reliability and speed improvements by designing microservices architectures, building real-time systems, and crafting secure APIs (REST/gRPC) backed by caching, observability, and performance optimization. Highlights include scaling Go microservices to 100K+ requests/sec, reducing API latency by 40%, and cutting settlement time from 60s to 200ms. I also architected event-driven reconciliation with Kafka to achieve 99.99% data consistency and used OpenTelemetry/structured logging to slash debug time by 50% and reduce incident resolution time by 30%.

I care deeply about clean architecture and seamless interfaces between infrastructure and user interactions. I lead end-to-end SDLC work, mentor junior developers, and drive agile delivery using Docker, Kubernetes, and CI/CD pipelines. With strong security fundamentals (OAuth2/JWT, RBAC, SAST/DAST, secure API design), I’ve supported compliance goals such as PCI-DSS awareness while implementing maker-checker workflows for fraud prevention.
