I build scalable multi-tenant SaaS platforms, cloud infrastructure, and web applications used across Indonesia.
IndonesiaWhat I'm looking for
I've built and deployed Godagang, a Shopify-like multi-tenant SaaS e-commerce platform that lets users create online stores in minutes. I designed its React.js, TypeScript, Node.js, and AWS architecture, including automated CI/CD deployment.
At PT. Tekno Jaya Indonesia, I develop and maintain web and mobile applications serving 25+ government institutions, enterprise clients, and thousands of users across Indonesia. My work spans production architecture, REST APIs, real-time Socket.IO features, authentication, role-based access control, Firebase integrations, testing, and long-term maintenance.
I improved frontend performance to Lighthouse scores of 100 on desktop and 92 on mobile, with LCP around 0.6 seconds, CLS below 0.01, and TBT around 0 milliseconds. I've also delivered internal systems for Indosat Ooredoo Hutchison, government platforms including Teknodesa and Teknolurah, and customer systems such as PDAM Jeneponto.
Earlier, I enhanced enterprise applications at Transcosmos Indonesia, mentored international web-development students in Germany, and led engineering and digital marketing teams as an IT Manager. I enjoy owning systems end to end, from architecture and development through deployment and maintenance.
