I'm Humayun Ahmed, a software engineer. Streamlet is a full ad-free YouTube client for Android — streaming, offline downloads, a music mode, Google sign-in — that I designed and built solo, entirely on a phone.
Everything people pay for elsewhere — ad-free, background play, offline, a music library — with your data staying on your own device.
Watch and listen with zero interruptions, foreground or background.
A Spotify-style tab with a full now-playing screen, liked songs and playlists.
Export real .mp4 videos and .m4a audio straight to your Music & Movies folders.
Optional Google sign-in syncs your real subscriptions and channel — read-only.
Mini-player, PiP, adaptive quality, Shorts, comments, community posts.
No ads, no trackers, no server. Everything lives on your device.
Streamlet isn't a wrapper — it solves real problems: adaptive streaming, stream muxing, OAuth verification, background media. Built end-to-end in Kotlin.
Video-only + audio streams paired live, adaptive quality up to 4K, and a custom fix for server-side throttling.
Separate HD streams muxed into one playable file with Android's MediaMuxer — no re-encoding, no quality loss.
Google sign-in with a verified consent screen, hosted privacy policy, and a published, verified app — the full production flow.
I'm a software engineer with a background spanning networking & telecom (SIGTRAN, SBC) and full-stack development. I like taking an idea all the way to something people can actually install and use — Streamlet is the proof: a complete Android app, architecture to release, built and shipped solo. Open to Android and full-stack work, freelance or full-time.
Android 8.0+ (APK). Your phone may ask you to allow installs from your browser or files app — that's standard for any app installed outside a store. Google sign-in is optional; the first sign-in shows a one-time "unverified app" notice (Advanced → Go to Streamlet).
