What I'm looking for

I seek senior backend/SRE roles in cloud-first teams where I can improve performance, observability, automation, mentor engineers, and drive scalable, reliable production services.

I am a Senior .NET software engineer and SRE with a track record of building high-throughput, resilient systems and driving measurable performance gains. I designed a .NET 8 microservice that processes 500 events/sec at ~25ms latency, refactored EF Core data access to reduce round-trips, and tuned SQL to cut worst-case query time from 10s to 200ms while lowering CPU by 60%.

I focus on observability, automation, and cost-efficient cloud operations—implementing OpenTelemetry, Prometheus/Grafana monitoring, distributed tracing, and CI/CD automation to reduce downtime and MTTR. I enjoy mentoring teams, improving system design, and delivering reliable, scalable services in production.
