I've worked on a variety of projects, from simple websites to complex web applications. Here are a few of my favorites.

TalentLoop

TalentLoop

TalentLoop is an AI-powered interview platform that conducts realistic, voice-based conversations with candidates using digital recruiters. Built with Pipecat and Tavus, it delivers adaptive, context-aware interviews through RAG and a modern Next.js interface.

JobNexus

JobNexus

JobNexus is an autonomous AI agent that streamlines the entire job hunt—from discovery to interview prep. It uses Gemini-powered LLMs to analyze resumes and semantically match them with high-intent job listings. Beyond just finding jobs, it automates hyper-personalized cold outreach campaigns and features a real-time, voice-based AI interview coach (built with LiveKit) to simulate technical rounds.

Hackathons

I like building things

Currently during my time at uni, I have attended 1+ hackathons. People from around the country would come together and build incredible things in 2-3 days. It was eye-opening to see the endless possibilities brought to life by a group of motivated and passionate individuals.
