About Me

I am a Software Engineer with over 1.5 years of experience in full-stack development, primarily using the MEAN stack and Sails.js. I have a strong background in developing RESTful APIs, dynamic front-end interfaces, and end-to-end web applications.

Currently, I work at Simato Vas Solutions, where I design and ship customer-facing products, integrate AI models (Gemini, OpenAI), and optimize performance using tools like Datadog RUM and Google Analytics 4.

I hold a BSc (Hons) in Software Engineering from Cardiff Metropolitan University (2023–2025). I am known for quick learning, problem-solving, and writing clean, maintainable code.

Open Source

Contributing to the community by maintaining and improving existing tools.

Forked & Maintained
npm package
cordova-hot-code-push-cli-renew-20
A renewed version of the Cordova Hot Code Push CLI, updated to support Node.js 20+.

The original library was abandoned and lacked support for modern Node.js environments. I forked the repository and implemented necessary fixes to ensure compatibility with Node.js 20 and above, allowing developers to continue using this essential tool in modern workflows.
