I am a Senior Software Engineer specializing in Go microservices and real-time data systems.
United StatesWhat I'm looking for
I am a Senior Software Engineer focused on designing and implementing scalable, high-performance microservices and backend systems using Go (Golang). I build real-time data pipelines, event-driven architectures, and robust API services that prioritize reliability and maintainability.
Across fintech, analytics, and streaming domains I have improved API response times by 25%, increased system throughput by 30%, and helped platforms achieve high availability (up to 99.99%+). I implement automated testing (over 90% code coverage), observability with Prometheus and Grafana, and cost optimizations for cloud storage.
I embrace cloud-native technologies, container orchestration, and accessibility best practices (WCAG 2.0 AA), and I enjoy delivering end-to-end solutions—from backend microservices and data pipelines to React/Angular operational dashboards—while driving measurable operational and business improvements.
