NIT Patna B.Tech Mechanical, 2027

I build machines that have to work out where they are and what they are looking at — a racing car with no driver, a drone mapping a mine where GPS cannot reach, a camera sorting waste on a moving belt. Most of my useful work has been figuring out why something failed when the obvious explanation was wrong.

Where I have worked

three placements
May–Jul 2026
New Delhi

Shoonya Recycling

Product Analytics & Computer Vision Intern
  • An automated sorting line was missing throughput and nobody could say why. I owned the diagnosis and the fix, working between engineering and operations.
  • My first assumption was the model needed more training data. It did not. Comparing misclassifications against what physically happened on the belt showed the failures clustered on motion blur and underexposure — an input problem, not a model one.
  • Fixed with CLAHE contrast enhancement and a move from a CNN to a vision transformer, whose global attention holds up where local texture is unreliable.

Vazirani Automotive

System Design Intern
  • Designed an axial fan compressor doing two jobs at once: generating downforce and feeding forced-air cooling to the battery pack.
  • Ran the baseline CFD in ANSYS — a blade passage meshed in TurboGrid to a 3 µm first cell, then the 11-blade, 12,000 rpm stage solved in CFX with SST k–ω at 0.07 kg/s.

Jodhpur

IIT Jodhpur — School of AI & Data Science

Robotics Research Intern
  • Fused camera, ground-penetrating radar and IMU streams from UAV trials into one perception pipeline, handling three different sampling rates and failure modes.
  • Built the evaluation harnesses that made detection performance legible across terrain, turning an inconclusive result into a roadmap the team acted on.

Things I built

six

F1/10th autonomous racing stack

ROS, C++, Python, Gazebo — Jul to Sep 2025

Nobody assigned this one. A full autonomous racing stack on Linux: 2D LiDAR SLAM with particle-filter localisation, closed-loop Pure Pursuit tracking, and a reactive gap-finding controller that picks a line through obstacles at speed.

Search-and-rescue UAV

Python, PyTorch, Webots — May to Jul 2025

Two sensing modes for finding people: YOLOv5 on the surface, simulated ground-penetrating radar below it. 84.7% detection confidence across 50+ runs. The part worth talking about is not the number — it is knowing which conditions made each sensor lie.

Mapping a mine with no GPS and no light

ROS2, Gazebo Fortress, UKF — TEXMiN Chanakya Fellowship

Underground tunnels defeat visual localisation: no ambient light, and brick walls that repeat every few metres so every frame looks like the last. An unscented Kalman filter fusing 100 Hz IMU with sparse visual features and LiDAR cut positional drift 82.4%, down to 0.07 m over a 60 m gallery. I am first author on the paper.

Industrial autonomous mobile robot

Fusion 360, kinematics, structural analysis — Jan 2026

A 500 mm cube carrying 20 kg at 1 m/s, drivetrain sized from first principles to a 2.0 safety factor. 6 mm aluminium base plate, an ABS mezzanine isolating the compute from motor vibration, and a TS35 DIN rail so standard components mount without custom brackets.

Why half a good idea made things worse

ANSYS Fluent, LES-WALE, Ffowcs Williams–Hawkings

Owl-inspired serrations on a UAV propeller, three geometries, transient large-eddy simulation. Full-span serration cut noise 3.87 dB. Serrating only half the blade made it 1.87 dB worse — and the cause was not the serration but the junction between treated and untreated sections. The transition was wrong, not either half.

Health Atlas — EY Techathon 6.0

Multi-agent AI, NLP, Streamlit, Figma — semifinalist from 115,000+ entries

A healthcare analytics product taken from research to working software in a competition sprint. Market and competitor research first, then requirements and wireframes, then a multi-agent pipeline with an NLP layer that turns unstructured reports into ranked KPI dashboards someone non-technical can actually read.
