What I'm looking for

I'm looking to build secure, scalable mobile and digital-transformation products, particularly in fintech, IoT, and real-time systems. I'm open to relocation to Saudi Arabia and value opportunities to lead delivery, mentor engineers, and improve platform architecture.

I've delivered mobile and web products across fintech, IoT smart home, gaming, e-commerce, healthcare, and real-time communication for DPL, Innovative Solution, Objectual Systems Limited, and Brainiac Studio.

At DPL, I lead mobile delivery for iApartments, architecting an MQTT-based IoT layer for 1,000+ smart devices and reducing latency by about 40%. I also strengthened OAuth 2.0 and JWT-based access control, reduced crash-affected users from roughly 10% to under 1%, and shipped 8+ iOS and Android release cycles on time.

For Comera, I re-architected an XMPP messaging platform to reduce server costs by about 20% and message latency by about 25%. I designed high-availability REST APIs, improved backend response times, and used Redux to eliminate many production UI inconsistency bugs.

I'm focused on React Native, mobile architecture, secure authentication, real-time systems, and clean, scalable delivery. I enjoy mentoring engineers, improving release processes, and using Agentic AI workflows to help teams ship features faster.
