About
Engineering payments, cloud at scale
I build the infrastructure behind money that moves. At Takamul AI, I'm engineering the UAE's retail CBDC (Digital Dirham) — an event-driven wallet platform on Java 25 and Spring Boot, with multi-realm Keycloak IAM and Vault-backed post-quantum cryptography securing every transaction. Before that, at Network International, I helped ship the UAE's first Apple Tap to Pay (SoftPOS) solution, from concept to production.
Eight years in, the focus hasn't changed: distributed systems that hold up under real financial load. I work primarily in Java, Spring Boot, React, and Go, building cloud-native microservices where correctness and performance both matter — because in payments, neither can slip.
Open to conversations about backend architecture, fintech infrastructure, or where secure, scalable systems are headed next.

Where I've worked
Core engineer on the CBUAE retail CBDC (Digital Dirham) platform — a production-grade digital-currency wallet ecosystem for the UAE Central Bank, spanning an event-driven backend, a React Native wallet app, an institutional portal, cryptography, IAM, and API-gateway performance.
- Architected the platform's programmable-wallet layer — designed the Smart Parent (parent-child) and MoCE Smart Social (government welfare disbursement) wallet flows as its first Smart Wallet Types, built on an embedded Lua smart-contract sandbox that enforces spend rules, allowlists, and disbursement caps deterministically without platform code changes.
- Owned the low-level design (LLD) for the platform's highest-scrutiny flows — parent-child wallets, multi-LFI sanctions/AML screening, and RBAC/identity federation — for a national central-bank digital currency platform.
- Designed and published a Vault-backed hybrid classical + post-quantum cryptography library (ML-DSA-87 / ML-KEM-1024) as a reusable Spring Boot starter with crypto-agility (runtime algorithm hot-swap), adopted platform-wide across the CBDC backend.
