About

I like building backend systems that are simple, reliable, and fast.

Backend-focused engineer from IIT Jodhpur. Most of my work is around distributed systems, APIs, and performance-critical applications.

I believe good engineering is invisible. It just works, for longer than anyone expected.

Experience

Undergraduate Researcher — IIT Jodhpur

  • Federated learning research with FedMeet, reaching 85% accuracy on meeting client sensor data.
  • Built an IMU-based engagement system with XGBoost and ONNX, achieving 91.19% cross-validation accuracy.
  • Integrated the model into backend workflows with communication-aware updates and productivity feedback.

Jun 2025 - Jul 2025

Bachelor Project (Research and Engineering) — IIT Jodhpur

  • Designed a three-phase pipeline that turns natural-language intent into secure Solidity contracts.
  • Built validated JSON extraction, rule-constrained generation, and automated compilation repair.
  • Integrated Slither, Mythril, and Semgrep with LLM-based patching for vulnerability detection and fixes.

Projects

01

Live

Well-Log-Analyzer

Full-stack sensor data platform processing 50,000+ rows across 100+ channels. Reduced frontend rendering latency by 90% via Intelligent Windowed Downsampling and hit 10,000+ rows/sec backend throughput with async pipelines. Ships a Groq-powered GeoBot (Llama 3.3-70B) with streaming responses and persistent chat history.
