About

I am a backend focused full stack developer with hands on experience building and scaling production grade systems in startup environments. I primarily work on backend architecture, API design, and data intensive services, with a strong focus on performance, security, and reliability. I work across the full backend lifecycle, from designing RESTful APIs and authentication workflows to implementing caching, rate limiting, idempotent APIs, and scalable system architecture. I have delivered ecommerce platforms, internal dashboards, and content driven applications, consistently improving response times, database efficiency, and production stability. I am comfortable taking end to end ownership of backend systems, including database schema design, query optimization, Dockerized deployments, and AWS infrastructure management. I enjoy solving real production problems and reducing operational overhead through better architectural decisions. I thrive in fast paced startup environments where ownership, clarity, and execution matter. I focus on writing maintainable code, building resilient backend systems, and shipping features that directly improve product reliability and user experience. Core skills: Node.js, Express, PostgreSQL, Redis, Docker, AWS, REST APIs, backend architecture, performance optimisation, secure systems.
