About this gig

Go services that stay simple as they grow the way Go is meant to be written.


WHAT YOU GET

- Idiomatic Go: small interfaces, explicit errors, no panic-driven control flow

- net/http or chi/gin/echo, your preference

- Postgres with pgx or sqlx, plus real migrations

- gRPC and protobuf when you need typed contracts

- Context propagation, timeouts and graceful shutdown done properly

- Table-driven tests and the race detector run before delivery

- Dockerfile, docker-compose and a deployment note


WHAT I CAN BUILD

- REST or gRPC services from a spec

- Microservices with queues (NATS, RabbitMQ, Kafka)

- Background workers and cron-style jobs

- CLI tools with cobra

- Rewrites of slow Node or Python services


WHAT I WON'T DO

- Ship goroutine leaks or unhandled errors

- Pretend a race condition is fine because the test passed once


WHY ME

Seoul National University trained engineer (BS + MS, Mechanical & Aerospace Engineering) and sole author of a programming book published by Apress. I write Go that reviewers do not have to babysit.
