I build backend systems that hold up in production. Over the last three years I've worked on platforms serving millions of users - a financial ledger service at a B2B commerce company that handled all company transactions, a recommendation cache at a telecom platform that cut latency by 30%, and a notification pipeline that ran on 80M+ subscriber infrastructure. These weren't side projects. They were mission-critical systems with real consequences if they broke. My main tools are Golang and Node.js on the backend, with React and Next.js on the frontend when needed. I'm comfortable across the full stack - APIs, microservices, databases, and integrations. I've worked with Kafka, Redis, PostgreSQL, MongoDB, Docker, and Kubernetes in real production environments, not just tutorials. I don't just write code to close tickets. I look at the actual problem first. If there's a better way to build something, I'll tell you before I start, not after you've paid for the wrong solution. I'm currently based in Melbourne, Australia, and I work with clients across different time zones. I'm available for both short-term builds and longer ongoing work. If you need something built properly and on time, let's talk.
