I'm Muhammad Daffa Alfandy — a full-stack engineer with 5+ years building scalable backends and full-stack apps in Go, PHP, Python & TypeScript. I care about clean architecture, measurable performance, and shipping fast with AI in the loop.
01 — About
A backend-leaning generalist.
My focus is the parts users never see but always feel — REST APIs, data models, and the architecture that keeps a product fast as it grows. At Mekari I cut the Run Payroll process time by up to 50% and helped move a core domain from PHP to Go.
I like owning things end-to-end: research, RFCs, rollout strategy, and the release process itself. I've led a Gitflow overhaul across three repos, driven cross-team initiatives, and mentored junior engineers along the way.
Lately I build with AI in the loop — LLM API integration and AI-assisted development — to ship features faster without cutting corners on tests or clean architecture.
