Software Engineer

Hi, I'm Alvin Wilta, a software engineer from Indonesia, working across the stack with a backend bias. I like cutting latency, untangling complex stuff, and shipping code that quietly does its job. Drawn to optimizations, automating the boring stuff, exploring new tech, and building little tools that make life easier.
My interests:
Always down to chat about tech, how money works, or side projects. Reach out if you're building something interesting, hiring, or just want to talk about running!
CURRENT FOCUS
Marathon preparation ยท Learning finance ยท Building with AI ยท Open to relocation abroad
Want the full breakdown of the philosophy, decisions, and trade-offs behind this site?
READ THE BUILD WRITE-UPOne of the little tools I built for this site, a renderer for the decoration circles. Shipped as a playground. Try it!
Interactive builder for the site's geometric SVG system. Tweak rings, polygons, rotation, and runes live, then export the result as SVG.
Companies I've worked at and problems I've shipped solutions for.
Technologies and tools I use to build scalable systems.
Full stack coverage across every layer and domain. End to end.
Projects I've built, templates, tools, and experiments built outside work.
This site. A dual-theme portfolio built with Next.js 15 on Cloudflare Workers, swapping between magic and cyber aesthetics. Read the blog for the philosophy, frontend showcase, and backend optimizations behind it.
