Full-Stack Engineer with 5+ years building production-grade MEAN/MERN applications for SaaS, fintech, and enterprise clients. I architect scalable systems end-to-end — from Angular (v8–20) frontends with signals, SSR, and design systems, to Node.js/NestJS/ExpressJS microservices backed by MongoDB, PostgreSQL, and Redis on AWS. What I've shipped: - Multi-tenant SaaS platforms handling thousands of concurrent users - Real-time dashboards over WebSockets with sub-200ms p95 latency - Microservices architectures that cut inter-service latency by 75% - MongoDB optimizations that took queries from 500ms → 75ms What makes me different: I don't just write code — I optimize, scale, and own. I've cut page loads by 45%, dropped API response times from 800ms to 120ms with Redis, and led code reviews that raised test coverage past 85%. I integrate AI/GenAI into real products. Available for remote contracts (UK/US time zones friendly). Fast communicator, async-first, and I ship.
