What I'm looking for

I seek a remote or hybrid role leading backend or platform engineering—building scalable, low‑latency cloud services, mentoring teams, and improving reliability and delivery.

I am a Senior Full‑Stack Engineer with 10+ years building scalable cloud‑native platforms and high‑performance APIs across e‑commerce, fintech, and enterprise SaaS. I specialize in Golang microservices, GraphQL APIs, distributed systems, and optimizing PostgreSQL and Redis for low‑latency production services.

I've designed and implemented cloud deployments using Docker and Kubernetes across GCP, AWS, and Azure, architected event‑driven systems with Kafka, and integrated payment and authentication flows (Stripe, PayPal, OAuth2, OpenID Connect). I consistently improve API latency and throughput, deploying resilient services that support tens of thousands of daily requests and high transaction volumes.

I mentor engineers in cloud‑native practices, TDD, and clean architecture, and I automate delivery with Terraform, GitHub Actions, and Azure DevOps. I bring a pragmatic focus on reliability, performance tuning, and scalable system design to help teams deliver robust production platforms.
