Backend and API development in Go, Ruby on Rails and Node.js

Backend services and APIs built to be correct under load, not just correct on the happy path.

WHAT YOU GET

- Services and APIs: REST and gRPC, versioning, pagination, auth, rate limiting, clear error contracts
- Event-driven architecture: Kafka or queues, background jobs, idempotency and dedupe, dead-letter queues and replay
- Third-party integrations: payments, CRM, ERP, and any partner API that retries, rate-limits or goes down
- Databases: schema design, migrations without downtime, query and index tuning
- Production readiness: OpenTelemetry tracing, dashboards, alerts and SLOs, CI/CD pipelines

STACK

Go, Ruby on Rails, Node.js / TypeScript, Python. PostgreSQL, Kafka, Redis, Docker, AWS.

BACKGROUND

10+ years in backend and platform engineering, including a petabyte-scale ETL platform with hundreds of connectors, Kafka and gRPC between services, and SLOs on every critical path.

HOW WE WORK

Small reviewable increments, tested code, weekly written updates, and documentation the next engineer can pick up. I will tell you when a simpler solution exists, including when it means less work for me.
