I'm Mustafa Erdem Köşk. Most people call me Erdem. I live in İzmir and have been writing software since 2014.

I work on backend systems — the unglamorous part of software where things either hold up or fall apart. I like understanding how stuff works, fixing messy problems, and learning things I didn't know a month ago.

Happiness should be a function without any parameters.

Tools I reach for

Go Node.js TypeScript Kafka Debezium RabbitMQ Redis MongoDB PostgreSQL Express Fastify Docker Microservices Developer Tooling
