✨ About me

Lateral-entry B.Tech CSE student at Shiv Nadar University (batch of 2027), focused on AI and Data Science. I like turning ideas into things that actually run: LLM agents, simulators, search systems and a bit of hardware. I solve problems on LeetCode in C++ and prefer a clean mathematical approach over brute force.

🌱 What I'm up to right now (click to open)
  • 🏎️ Polishing F1 Strategist, an LLM agent that calls pit-wall strategy, for the Meta PyTorch OpenEnv Hackathon
  • 💧 Building Virtual Tank Battery for the Schneider grid-reliability challenge (hardware and firmware)
  • ⚖️ Hacking on LexShift, legal search over Supreme Court judgments, for an IR hackathon
  • 🩺 Working on TG-LiteNet, retinal vessel segmentation for my project course
🎯 Quick facts (click to open)
  • I train models with GRPO and enjoy reward design more than I should
  • Most comfortable in Python and C++, happy in React when a UI is needed
  • Hackathons are my favourite way to learn fast
  • Ask me about RL environments, simulators or competitive programming

🏁 Contribution Grand Prix

Contribution Grand Prix: my last year of contributions drawn as an F1 circuit

Every segment of the track is one day of the last year. A GitHub Action redraws it every 12 hours.

🔧 How the Grand Prix works (click to open)
  • Each of the last 364 days is one tiny segment of the circuit, coloured by how many contributions I made that day
  • The three sector labels add up each third of the year, and the best one is highlighted in purple
  • Months become a tyre strategy: busy months are soft tyres, quiet months are hard
  • A GitHub Action calls the GitHub API, redraws the SVG and commits it every 12 hours. No third-party service is involved
  • Open the interactive site to hover over any day
