Senior Go Backend Developer | APIs, HTMX & MySQL

Senior software engineer focused on Go backend and web application development with 8+ years of hands-on Go experience. I build and maintain reliable web apps, APIs, and integrations, and I’m comfortable working in existing codebases as well as developing new features. My Go experience includes Gin and chi, API design, SQL/MySQL, Docker, and HTMX-powered interfaces. I also work with JavaScript/TypeScript and can maintain PHP/WordPress systems when a project needs it. I’ve developed open-source compilers for Oberon and teach Go, algorithms, and data structures. I clarify requirements and scope before starting, share progress regularly, and discuss any work beyond the agreed scope before proceeding. If you’re building or improving a Go web application or backend service, tell me what you’re working on and where you need help.
