Backend / Platform Engineer focused on distributed systems, APIs, reliability, and production-oriented backend architecture.
I build systems around clear service boundaries, strong contracts, observability, failure handling, and reproducible infrastructure.
Polyglot checkout platform built with TypeScript, Go, and Rust.
Distributed payments, EdDSA authentication, idempotency, PostgreSQL, OpenTelemetry, cross-service contracts, end-to-end testing, and CI.
Exactly-once payment processing in Go, designed for retries, concurrent requests, multiple replicas, and partial failures.
Reusable OpenTelemetry setup for Node.js services with traces, metrics, log correlation, Jaeger, Prometheus, and Grafana.
Architecture-as-code toolkit combining arc42, C4, ADRs, Mermaid, and CI validation.
