Engineeringthat survivesproduction.
I'm Ahmad Fahruddin Salim — a Fullstack Web Developer crafting structured, scalable web systems from database architecture to pixel-perfect interfaces.
Fullstack Web Developer with 3+ years of experience building structured, scalable, production-ready web applications — end to end, from database architecture and REST APIs to responsive, efficient interfaces.

Fullstack Web Developer · Malang, Indonesia
I work across the entire stack — responsive interfaces with React, Vue, and AngularJS on the front, REST APIs built with Laravel, ExpressJS, Go, and Node.js on the back.
On the data side, I design relational schemas, write complex queries, and tune performance for large-scale datasets. I integrate third-party services — WhatsApp API, META API, and other external platforms — directly into production systems.
I care about more than shipping features. Long-term code quality, system maintainability, and making sure every layer of the stack survives real-world load — that's the standard.
