I refactored and optimised legacy codebases to align company coding standards, and branding requirements. I engineered modular, reusable, and highly testable components, leveraging Test Driven Development (TDD) to ensure code reliability and maintainability. My responsibilities included architecting and deploying Node.js and serverless solutions, implementing secure RESTful APIs, and integrating third-party libraries to extend system functionality. I translated detailed technical specifications into robust front-end components, ensuring pixel-perfect UI fidelity and seamless user experiences.

I designed and implemented distributed, low-latency, and highly available applications with a strong focus on security, including data encryption and access control. I integrated scalable data storage solutions, normalised and optimised database schemas, and managed OAuth 2.0 and JWT-based authentication flows to enforce secure access. Throughout the SDLC, I championed CI/CD pipelines, automated testing, and code reviews to uphold best practices in software engineering, code quality, and system security.
