What I'm looking for

I’m looking for a product-focused team where I can build full-stack features in React and Node.js, integrate AI APIs, and own quality with testing—while growing through Agile delivery, strong code reviews, and CI/CD.

I’m a Full Stack Developer with 1.5+ years of production experience at Capillary Technologies, supporting an enterprise retail loyalty platform serving 30+ countries.

I’ve shipped an end-to-end AI-powered customer intelligence feature using the Google Gemini API, taking it from backend prompt engineering and API handling to a React.js dashboard UI that delivered insights into production.

On the application layer, I delivered 15+ reusable React.js components and 10+ secure Node.js/Express.js REST APIs with input validation, structured JSON contracts, and robust error handling—streamlining data flows with Redux Toolkit.

I also focused heavily on quality and reliability: I authored 50+ E2E and automation tests with WebdriverIO and Jest, and I resolved 20+ critical production bugs to improve uptime and stability in an Agile/Scrum environment.
