Projects

Things I’ve built. Some for millions, some for myself.

Side Projects

dawatnama.app

2026 — ongoing

dawatnama.app

Beautiful digital invitations for weddings and events. Built it because every desi invitation app was either ugly or overpriced. A weekend project that stuck — and my excuse to learn modern web development properly (Next.js, Tailwind, Vercel).

Tech: Next.js, Tailwind, Vercel

Islamic Finance App (Planning)

2025

Proper Zakat calculation with Hijri calendar. Wasiyat management. Halal investment tracking.

Still in design phase. Want to get this right before building it.

Professional Work

Cashia Consumer Experience (Engineering Manager)

2026 — Present

Leading the squad that owns all customer-facing digital channels at Cashia — a fintech building payments infrastructure for Africa. Consumer Mobile (Android + iOS via KMM), Web Portal, and Onboarding.

Scope: 5 engineers, 3 platforms, everything the customer sees.

Cashia Platform Foundations (Lead Mobile Engineer)

2025 — 2026

Built the platform infrastructure that underpins how every Cashia feature ships: Feature Flag framework (adopted company-wide), Forced App Update mechanism, mocking layer for parallel frontend/backend development, unified login/sign-up client-side flow.

Features shipped: Native Card Top-Up (CyberSource + Cardinal SDK), M-PESA Cash-Out, Request Money Fulfilment.

Tamara Card

2023 — 2025

Built the entire card issuance feature on Android from scratch — architecture, Network International SDK integration, Google Pay provisioning. One of the first BNPL cards in Saudi Arabia.

Foodpanda & Sister Apps

2021 — 2023

Growth features for 120M+ users across 20 countries at Delivery Hero. Spearheaded Jetpack Compose adoption (~3x faster UI development), A/B testing infrastructure, led KMM evaluation R&D.

Airlift Consumer App

2020 — 2021

From first line of code to 1M+ users. Built both the passenger and driver apps. On-device ETA calculation engine, contactless passenger onboarding.

Open Source

Small contributions to various Android libraries. Nothing major yet.

Side Experiments


I believe in building things that solve real problems. Sometimes that’s for millions of users, sometimes it’s just for me.
