My journey began at the intersection of Fintech reliability and E-commerce scalability. I’ve spent my career helping startups bridge the gap between a frontend that looks premium and a backend that is bulletproof.
Whether it’s optimizing MongoDB aggregation pipelines for an NBFC or architecting AWS SQS decoupled workers for AI processing, I focus on the technical details that prevent downtime and drive business growth.
As a freelancer, I operate as your on-demand CTO. I handle everything from the initial UI sketch in Tailwind to the final Kubernetes deployment.
