Systems-focused backend engineer specializing in distributed computation, cloud-native microservices.
What I'm looking for
I am a systems-focused backend engineer specializing in distributed computation, operating systems, and networking, with 15+ years of professional experience and a strong emphasis on cloud-native microservices and infrastructure abstractions.
I have delivered production-grade platform services and features at scale across AWS, GCP, Azure, and bare-metal environments, including multi-region HA standards, multi-cloud dataplane abstractions, and Consul-as-a-Service. I prioritize MVP-first delivery, SLOs, continuous delivery, and measurable customer value while driving cross-functional alignment with security, SRE, and legal stakeholders.
My technical strengths include Go, Python, gRPC, protobuf, PostgreSQL, Kubernetes, and HashiStack tooling, and I combine hands-on engineering with leadership in platform strategy, incident response, and mentoring to ship resilient systems and evolve products rapidly.
