Message

At Hike, I developed production-ready backend microservices in Java and Spring Boot. I optimized database queries and added caching layers, reducing API latency by 25%.

I also built and deployed the “Spin-the-Wheel” gaming reward module, including probability logic and secure reward processing. For chat history retrieval, indexing and N+1 query fixes reduced query execution time by 45%.

At Next Step Veteran Pvt. Ltd., I developed and deployed full-stack web features using React, Node.js, Express, and MongoDB. I implemented REST API endpoints for authentication and data management, and helped resolve production issues.

In my projects, I built an AI medical voice assistant and an AI-powered interview preparation platform. I also created ResumeAnalyzer, a resume evaluation tool that uses the Google Gemini API to provide feedback on ATS compatibility, keywords, and content gaps.
