About

A Frontend & Full-Stack Developer with strong experience in manual, web, and mobile testing, I bring a unique blend of development expertise and QA discipline. My background in React, Node.js, Express, PostgreSQL, and AI-powered workflows allows me to not only test applications but also understand how they are built, ensuring deeper insight into potential bugs and usability challenges.

I have successfully contributed to projects like ShopWise (AI-powered e-commerce), WatchWise (AI movie recommender), and Amazon Review Sentiment Analyzer (n8n workflow automation) where I played dual roles in development and quality testing.

✔ Collaborated with dev teams to debug workflows in n8n automation pipelines.
