Software engineer
building distributed,
well-made systems.

I design and ship backends and interfaces that stay calm under load. Currently working on AI agents, video infrastructure and CDN.

All projects

  1. Self-hosted deployment platform

    Deploy apps to Linux servers you already own, with automatic HTTPS, health-checked rollouts and one-click databases. Self-hosted for free or as a hosted service.

    Rust · Axum · PostgreSQL · Docker2026

  2. Video platform

    Video transcoding and delivery. Upload once and get an adaptive stream that plays on any phone, on any connection, with signed playback and per-minute billing.

    Go · ffmpeg · PostgreSQL · ClickHouse2026

  3. Content delivery network

    A CDN in front of a website or storage bucket: custom domains with free certificates, cache rules, a firewall and real-time visitor analytics.

    Go · OpenResty · PostgreSQL · ClickHouse2026

  4. Live streaming

    Live streaming on your own channel. Go live from OBS or a browser, reach viewers as adaptive HLS, and find the recording already waiting as a video.

    Go · MediaMTX · ffmpeg · S32026

  5. AI order-confirmation calls

    AI phone calls for online shops in Bangladesh: confirms cash-on-delivery orders and recovers abandoned carts automatically, in Bangla.

    Go · PostgreSQL · Redis · React2026

I'm Ebn Sina, a software engineer in Bangladesh. I build backends in Go, Rust and C++ on PostgreSQL, ClickHouse and Kafka, and interfaces in Svelte, and I care most about the parts nobody sees: clear errors, systems that recover on their own, code that stays small.
