What I'm looking for

I’m looking for remote B2B opportunities (or relocation) where I can build high-load Go services, improve reliability and performance, and mentor teams—especially in fintech/cloud systems with ownership across design, delivery, and operations.

I’m a Senior Golang developer with 6.5+ years of experience in Fintech, HighLoad, and Cloud environments. I focus on scalable system design for 10k+ RPS workloads and 50TB+ data processing, with strong problem-solving and collaboration habits.

At UCB, I designed and implemented an end-to-end high-load trigger generation system for near real-time credit bureau signal delivery (30M triggers/day). I coordinate across 4+ teams, mentor and onboard developers, and lead code reviews and knowledge-sharing to raise codebase quality.

Previously, at Middle Golang Developer, I built a reporting system handling 50TB+ of data and drove key performance and reliability upgrades. I migrated services from REST to gRPC, improved integration quality, and transitioned file processing to AWS S3 API to remove bottlenecks; I also set up CI/CD and k8s deployment for 400+ service instances with Ansible support across 20+ repositories.

Earlier, I developed Go-based automation for cloud cluster deployment using OpenStack APIs and created monitoring with Prometheus and Grafana, reducing MTTR by 50%. With a deep academic and practical foundation in Backend Development, Computer Science, and Data Engineering, I bring both engineering discipline and data thinking to every system I build.
