About

Software Engineer — TypeScript, Go, Node.js, React, AWS · Bali, Indonesia

Portrait of Widhi Adnyana

I'm a full-stack engineer with 8+ years of experience building production-grade web platforms — from system architecture to deployment. My core strength lies in backend engineering, but I'm equally comfortable owning the full stack when needed.

I'm currently a Senior Software Engineer at PropHero. Before that I spent over seven years at igloocompany, where I led the iglooworks platform engineering team — driving backend architecture decisions, mentoring engineers, and delivering features for a smart lock ecosystem used across Southeast Asia and beyond.

My toolkit includes Node.js, TypeScript, Go, React, and AWS, with hands-on experience in microservices, GraphQL, IoT (AWS IoT Core, MQTT), and CI/CD pipelines. I've also built embedded firmware for IoT devices using Raspberry Pi.

Based in Bali, Indonesia. Open to remote opportunities and international collaboration.
