At Taazaa Inc., I build real-time Java 17 and Spring Boot solutions supporting LENS and MAS integration for over 2 million New York motorists. I focus on SQL Server, agile delivery, and Kubernetes-based deployments.

Previously, I helped transition STC Pay into STC Bank for 8 million active users, improving a 50+ endpoint Spring Boot service by 25% with Redis and report generation by 60% with gRPC. Across qordata, INK Software Solutions, and DevTek.ai, I’ve delivered scalable microservices, AI SaaS campaigns, cloud infrastructure, and secure distributed services.
