I focus on REST APIs and concurrency-safe systems — the kind that hold up once real users and real data hit them, not just in a demo. What I bring to your project: API & Backend Architecture — I built a full-stack workflow system with AI-assisted automation that cut manual task setup time by 50% and improved developer efficiency by 40%. Performance Engineering — I reduced snapshot load times by 60% through query optimization and a better caching strategy. I'd rather find why something is slow than just patch around it. Auth & Access Control — I've implemented JWT-based authentication and role-based access control for multi-tenant systems, with test coverage using Jest. Bonus edge — I also work with Solidity for smart contract development, so if your roadmap ever touches Web3 or on-chain logic, that's covered too. Most of what I know about production-grade backend work — fuzzy search, geo-indexing, Redis caching, handling concurrency properly — I learned by actually building for real clients, not just from tutorials. I bring that same care to every project: clean code, tested endpoints, and clear communication along the way. If you've got a messy spec that needs to become a solid, scalable backend, let me know what you're building. I'll be straight with you about whether I'm the right fit, and if I am, how I'd approach it. less -
