I've built scalable backend services and high-performance REST APIs at Carclenx (Pexa), supporting production traffic of approximately 1,000 requests per second.

I design asynchronous pipelines with Redis Streams and worker services, secure authentication and RBAC flows, FSM-driven workflows, and resilient messaging and payment integrations. My work on analytics and payroll automation helped reduce service cancellations by 80% and manual HR effort by roughly 70–80%.

Across Cordova Educational Solutions and Quest Innovative Solution, I've modernized legacy backend modules, developed 30+ REST APIs, optimized database logic, and resolved production issues for LMS, booking, and business applications. I also work across the stack with Angular and React.js when end-to-end delivery calls for it.

Outside production work, I explore RAG systems, microservices, compiler toolchains, and distributed systems through projects including an enterprise knowledge platform, a distributed commerce platform, and a C-based build automation tool.
