I build scalable backend APIs, databases, and full-stack products for enterprise and startup teams.
IndiaWhat I'm looking for
I've built high-performance fintech interfaces at RIA Catalyst, shifting complex filtering and tier restrictions into backend middleware to improve frontend data rendering by 25%. I also integrated GraphQL, gRPC, React, LLM endpoints, Python, and vector databases for financial-data and RAG workflows.
As an independent consultant, I designed multi-tenant marketplace systems for Romya Electronics and real-time hotel inventory, booking, and CMS products for CareMyTrip.com. I've engineered Laravel REST APIs for 1,000+ daily active users, improved complex MySQL query time complexity by over 40%, and deployed resilient AWS infrastructure targeting 99.9% availability.
Across freelance, RGC Manager, and SpiceTech projects, I've delivered secure e-commerce platforms, employee-management tools, job portals, clinical-trial system migrations, and authentication systems. I enjoy owning system design through deployment while improving backend performance and translating business roadmaps into working products.
