I'm the backend engineer you call when your API is slow, your database is struggling, or your integration keeps failing. With 10+ years of production experience — including high-traffic systems serving millions of users — I've seen and fixed most backend problems there are. I work with: • Go, Node.js, PHP — for building reliable APIs • PostgreSQL, MySQL, MongoDB — for data that performs • Docker, Git, CI/CD — for smooth, repeatable deployments What I can do for you: • Diagnose and fix performance bottlenecks • Build clean, scalable REST APIs • Integrate payment gateways, CRMs, or external services • Optimize slow queries • Set up Docker-based development environments • Automate workflows with n8n (hands-on experience) My earlier Upwork work is from years ago — since then I've been building enterprise systems (see my employment history). I'm back on Upwork to bring that same enterprise-grade reliability to your project. Let's talk about what's broken — or what you want to build. I read every message.
