I'm Zaman, founder of Silifton, an engineering studio in Dhaka and Seoul. I build mobile apps, real-time video systems and developer tools, and I like owning a product from the first commit to the day it runs in production.
- Building: Silifton and its products, including Voxa RTC and Postora
- Focus: Flutter, real-time video (WebRTC, LiveKit), NestJS and Next.js backends, Linux servers
- Teaching: free Flutter sessions in the Silifton Discord community
- Ask me about: Flutter, Dart, real-time apps, PDF and text shaping, Linux
- Reach me: shamsuzzaman15-4031@diu.edu.bd · CV
Voxa RTC: an Agora-compatible real-time video engine you can self-host. Same API, your own servers.
bangla_pdf: correctly shaped Bangla text in PDFs, with real OpenType shaping, for Dart and TypeScript.
Pagewright: give an AI agent a real browser, with an MCP server and a Chrome extension.
git-vanish: an interactive terminal app that removes leaked files and secrets from every commit in git history.
Campus Saga: a Flutter app where students raise campus issues and administrators resolve them.
ClipStack: a free macOS clipboard manager with unlimited history, an overlay paste board and search.

If my open-source tools help you, a coffee keeps them going.
