What I'm looking for

I'm looking to build scalable, secure, cloud-native products from concept to production, lead modernization and AI-enabled engineering initiatives, collaborate with cross-functional teams, mentor engineers, and deliver resilient solutions for startups or global enterprises.

I've led modernization and architecture for Freddie Mac's securitization reporting platforms and Mashreq Bank's digital investments and wealth channels, building event-driven systems for high-volume reporting, trading, settlement, and payment workflows.

I design and implement Java and Spring Boot microservices using Kafka, Domain-Driven Design, REST APIs, GraphQL, Camunda, Redis, AWS, Azure, OpenShift, and Kubernetes. My work includes monolith-to-microservices transformations, JVM and database optimization, resilient transaction processing, CI/CD, DevSecOps controls, and hands-on production troubleshooting.

Across Emirates Airlines, Abu Dhabi Islamic Bank, National Bank of Abu Dhabi, Cobone, Dubai Customs, and NetSol, I've delivered booking, banking, e-commerce, government, and financial applications. I enjoy building POCs, mentoring engineers, defining engineering standards, and using GitHub Copilot, ChatGPT, and AI-assisted tooling to improve delivery, documentation, and code quality.
