Building scalable web experiences from pixel to server. I craft clean, performant applications with a passion for great DX and even better UX — currently shipping at PT Bimasakti Multi Sinergi.
I'm Krisdian — a fullstack developer based in East Java, Indonesia, with a background spanning frontend craft, backend engineering, data warehousing, and even graphic design. I bring a wide perspective to every project I touch.
Currently working in the Host-to-Host (H2H) division at PT Bimasakti Multi Sinergi, where I build and maintain PPOB transaction systems, migrate legacy codebases, write developer-friendly API docs, and support client integrations end-to-end.
Migrated transaction monitoring portal from CodeIgniter to Express.js + Next.js. Developed and optimized PPOB product transactions with PHP, Node.js, TypeScript, React, and Svelte including custom client integrations. Authored API docs with Docusaurus. Handled incident support, code quality improvements, and pre-sales technical assistance for H2H product integrations.
Translated UI/UX designs into responsive web interfaces. Integrated REST APIs, built reusable UI components (XBase-UI library on Buefy & Oruga), implemented OIDC authentication, executed unit tests, and led the Vue 2 → Vue 3 migration of legacy codebases.
Defined design concepts collaboratively across divisions and produced visual assets for various communication and marketing purposes.
