About me

Hi! I'm Kevin. I'm an AI Research Engineer working for TCS Research, India. In 2024, I graduated from Indian Institute of Engineering Science and Technology, Shibpur with a bachelors in Computer Science.

My research focuses on AI alignment and preference modelling i.e. designing methods that allow models to learn human judgement, taste and intent rather than imitate surface patterns. I'm particularly interested in distilling human novelty, creativity and preferences into learning systems. My work involves working across both text and image modalities, studying how these signals can be represented and measured.

For a Layman: I teach machines how to be more human :)

I'm great at building..

  • AI Systems

    Designer of evaluation frameworks for large language models. My work focuses on preference modeling, and building automated judges that measure alignment with human intent.

  • Backend and Distributed Systems

    I design backend systems that automate messy workflows and make data usable. I like building things that take raw inputs, process them cleanly, and produce reliable outputs without constant human babysitting.

  • Recommendation Systems

    I enjoy working on systems that model choice, how users behave, what they prefer, and how to personalize experiences without overcomplicating the math.

  • Creative Side

    Outside of work, I’m learning music production. Still early, but I like exploring how tech and creativity overlap.

Education

  1. Bachelors in Computer Science and Technology

    2020 - 2024

    Indian Institute of Engineering Science and Technology, Shibpur

Experience

  1. AI Research Engineer

    2024 - Present

    TCS Research

    • Engineered a preference modeling pipeline for creative story evaluation (LitBench dataset) by adapting the Inverse Constitutional AI framework: generated reasoning chains and adversarial debate prompts using GPT‑4/GPT‑5, clustered resulting evaluation questions into a “constitution” of preference principles, and trained a decision‑tree classifier as a final preference judge; this pipeline achieved 71.2% accuracy in predicting human‑aligned preferences (3.4 points above the 67.8% ICAI baseline) and culminated in a ICLR 2026 HCAIR workshop submission.

    • Engineered an LLM‑based Document Parsing System extracting structured data from 100+ technical specifications, achieving 4.6/5 on G‑Eval quality metrics—enabling automated knowledge retrieval

  2. Junior Python Developer

    2023 - 2024

    221B Baker Street

    • Built an ETL and analytics pipeline by ingesting Google Ads, LinkedIn, and HubSpot campaign data into BigQuery, enabling unified dashboarding and campaign insight generation for Middle Eastern client.

    • Automated campaign and ad ROI analysis workflows using Python Scripts and Automation Tools, reducing manual effort by ∼35% and cutting reporting delays.

    • Developed a Django-based Campaign Automation Tool with Redis and Celery; enabling personalized and scheduled email delivery, increasing campaign throughput by 40%.

    • Engineered a custom payroll solution within Odoo to automate complex Davis-Bacon Wage compliance, integrating strict data validation and audit logging to ensure regulatory accuracy and financial compliance for a U.S. construction client.

  3. Python Developer Intern

    2023

    221B Baker Street

    • Designed and deployed a Lead Generation Engine that generated verified email permutations from a 100K+ contact dataset of email records boosting lead generation.

    • Achieved ∼80% unit test coverage across core modules, ensuring reliability of lead generation pipeline.

    • This helped the Business Team to generate more leads and the lead generation went up by 24%

    • Gained comprehensive knowledge of online advertising and contextual ad mechanics.

  4. Mentee (SWE)

    2022

    Microsoft Engage

    • Built a collaborative filtering recommender system for a social media website (friend.ly) to recommend users to follow based on multiple criterion such as influence, mutual followers, search history and mutual interest.

    • Implemented algorithms including matrix factorization (SVD) and k-nearest neighbours (k-NN) to optimize recommendation accuracy.
