Four years,in order.

Education, an internship, two leadership terms and a conference paper — arranged the way they actually happened, including the part where a model scored 99% on training and 74% on everything else.

    Education

    B.Tech, Computer Science and Engineering

    Vellore Institute of Technology, Chennai

    Chennai, India

    Specialisation in Artificial Intelligence and Machine Learning.

    • Coursework across machine learning, deep learning, computer vision and explainable AI, carried into project work rather than left on the transcript.
    • Most of the systems in this portfolio started as coursework and kept going after the deadline.
  2. 2024 — 2025
    Leadership40+ member team

    Head of Visual Media

    VOICE-IT — VIT Chennai’s radio station club

    Chennai, India

    Led a 40+ member visual media team.

    • Owned the club’s visual output end to end — direction, shoot planning, edit and delivery.
    • Ran a 40+ member team across recurring shows and campus-wide campaigns.

    Machine Learning Intern — Deep Learning & Computer Vision

    Indira Gandhi Centre for Atomic Research (IGCAR)

    Kalpakkam, India

    Weld inspection was manual and inconsistent between inspectors. I owned an automated defect-localization pipeline end to end.

    • Fine-tuned a YOLOv8-L detector on high-resolution weld imagery, owning the pipeline from data to evaluation.
    • Curated and labelled the dataset, ran 100 GPU training epochs, and evaluated on precision, recall, F1 and mAP — 99.1% on training against 74.3% held-out.
    • Diagnosed the gap as overfitting, revised the dataset and splits, and presented the trade-offs and next steps directly to the scientific staff.

Availability

Open to internships and AI/ML roles.

Graduating May 2027, based in Chennai and comfortable remote. Happy to talk about applied ML, computer vision, explainability or anything adjacent.
