Engineering and scaling production-ready backend systems utilizing Node.js, NestJS, and TypeScript to support core application infrastructure. Architecting high-performance, secure RESTful/GraphQL APIs, managing database schemas, and implementing caching mechanisms to maximize data retrieval efficiency. Collaborating within engineering sprints to optimize system architecture, conduct code reviews, and drive backend performance tuning across platform features.

Sole engineer on 10+ full-stack SaaS platforms — owned the full delivery lifecycle: requirements scoping, database schema design, API architecture, frontend implementation, cloud deployment (AWS/Vercel), and post-launch support. Architected NestJS microservices backends with modular domain structure, dependency injection, and Redis-backed caching layers — cutting average API response times by 45% vs. baseline Express implementations. Built a personal library of 200+ reusable atomic UI components (Tailwind CSS + ShadCN UI) versioned in Git — enabling consistent design systems across client projects and reducing per-project UI build time by ~40%. Managed client relationships across US, UK, and European time zones — handled scope negotiation, milestone reviews, and technical documentation delivery; sustained 5-star ratings and 100% on-time delivery across all engagements

Built secure MERN stack research tools with real-time WebSocket data pipelines, achieving 99.9% system uptime during rigorous testing phases. Resolved 40+ high-priority production bugs and eliminated 25+ architectural bottlenecks; coordinated agile sprints and version control for a team of 5 developers.
