I build software that can be opened, run, tested, and argued with. My current work spans Rust desktop applications, TypeScript APIs, developer tooling, and small systems experiments in C. I also contribute documentation, tests, and Arabic localization upstream.
The standard I aim for is simple: a useful program, a legible repository, and claims that stop where the evidence stops.
A Windows-first desktop application for saving public video and audio. The project includes a native download queue, signed updates, publisher-checksummed tool installation, release provenance, URL and filename safety policy, unit tests, and desktop smoke tests.

Release v0.1.1 · CI · Security model
A maintained API for Quran, tafsir, azkar, hadith, prayer times, Hijri dates, and qibla direction. Each upstream request has a timeout. Failed or malformed responses move to the next provider while the API preserves one output shape. The repository ships an OpenAPI contract, health and readiness probes, tests, and a container build.

Live API · Documentation · OpenAPI 3.1
An experimental authenticated stream-cipher study in C. Version 2 separates keys, authenticates ciphertext and associated data, rejects tampering, and publishes deterministic test vectors. It is intentionally documented as research—not production cryptography—and recommends established AEAD constructions for real systems.

Release v2.0.0 · Architecture · Validation roadmap
A Cloudflare Worker that renders README-ready contributor grids as SVG. It handles repo, multi-repo, organization, and user scopes; deduplicates contributors across repositories; validates query input; and keeps tokens out of URLs and shared caches.

As of 28 July 2026, the public record shows 48 authored pull requests, including 37 merged changes. I count public results only so another reviewer can reproduce the number.
- Merged documentation fixes in NVIDIA/NemoClaw#5522 and discord/discord-api-docs#8408.
- Open test work in expressjs/express#7050, icon support in Material Icon Theme#3469, and Arabic documentation in webpack.js.org#8252.
- Ongoing maintenance across BonyanOSS and ctlib, plus Arabic localization through Crowdin.
The fuller ledger is in CONTRIBUTIONS.md.
My strongest repositories show the practices I care about: narrow public APIs, explicit failure paths, tests that run in CI, reproducible releases, security notes, and documentation that states limitations before benefits.
