Featured project
Majlis / مجلس
Your table. Your people.
Pre-launch · Android and iOS together
An Arabic-first social card game platform for iOS and Android.
Tarneeb, Trix and 400 are playable end to end: online with friends, at public tables with new players, with bots filling empty seats, or completely offline on the phone. The table is hand-crafted in 2D, with card sounds, haptics and an Arabic voice announcer.
My role: everything. Product and game design, UI, the Flutter app, the rules engine and bots, the backend, DevOps, cost control and the website.
Engineering highlights
One rules engine, two runtimes
The rules are written once in TypeScript. The server runs them to referee online tables; the app runs the very same bundle in embedded QuickJS for offline play. Every copy is checked byte-identical.
Server-authoritative multiplayer
Each table is a Durable Object on Cloudflare that validates every move over WebSockets. Hidden hands never leave the server; every seat gets its own filtered view.
Versioned rulesets
Every rule change bumps a ruleset version and a match keeps the rules it was dealt under, so a deploy never changes a game in progress.
Cheap at rest
Hibernating WebSockets, pings that don't wake the room, and bot moves planned in a single write keep idle cost close to zero.
A spend guard with a hard stop
A scheduled job prices the month's cloud usage and, near the budget limit, pauses new online games while matches in play finish and offline play keeps working.
Arabic-first, RTL done right
Right-to-left by default with a full English mode. Seat order and suit symbols are deliberately never mirrored, and a bundled suit font keeps cards identical on every device.
Privacy and safety by default
Analytics and crash reports stay off until the player consents. Rate limits, a profanity filter, reports and escalating chat mutes keep tables friendly.
Tested heavily
About 3,260 automated tests: 395 for the rules engine, 644 for the server in the real Workers runtime, and 2,221 for the Flutter app, plus simulator tests that play real matches.

About
A builder who ships
I'm a full-stack Flutter developer based in Brazil.
Majlis is where all of that comes together.
I care about quality you can measure.
My background: a postgraduate specialization in Software Engineering with Agile Methods (2024) from Universidade Cruzeiro do Sul. From October 2026 I work remotely as a React front-end developer at GoOn Associated, a company based in Curitiba, Paraná, Brazil, and I keep building Majlis alongside it.
