// About Me

Passionate about engineering
excellence
and clean code

I'm a Senior Backend Engineer and Technical Lead with 6+ years designing and delivering distributed systems on .NET and AWS. I specialize in microservices architecture, asynchronous messaging pipelines, and AI-integrated backend systems.

Currently at CAS Techno Sales (Frost Digital Ventures), I'm leading the transformation of a prototype into a production-grade platform — architecting AI-integrated microservices, async job pipelines with AWS SQS, Redis semaphore-based concurrency control, and real-time notifications via SignalR. Previously at Innovate Tech, I drove backend migrations, ETL pipelines, and AWS infrastructure optimization at scale.

I hold an MSc in IT & Applied Security and a BSc First Class Honours in Computing from London Metropolitan University, and I'm an AWS Certified Solutions Architect – Associate. I thrive on owning systems end-to-end — from schema design to production deployment.
