AI/NLP & Full-Stack Engineer

About Me

My journey as a full-stack developer began in 2022 with freelancing for clients across India, where I built end-to-end solutions and collaborated closely with clients. I later joined Mallow as a Project Intern (Backend Developer), which helped sharpen my backend skills and introduced me to structured, team-based development. After that, I interned at IIIT Hyderabad and subsequently became a Junior Software Engineer at LTRC, contributing to full-stack tools for linguistic research. A year later, I received an offer to pursue a Master’s by Research, which I’m currently in my second year of. Alongside academics, I continue to work on app development and AI research, blending innovation with practical impact.

My Journey

Bachelor of Engineering in CSE @ Karpagam institute of Technology

  • Oct 2021 - Feb 2023 Project
    Karpagam e-Governance Portal - Centralized Academic Management System
    • Developed an academic management system for student records, attendance, schedules, and grading, with role-based access control and background jobs (Redis Queue) for asynchronous tasks.
    • Implemented leave modules for students and faculty with online applications and approvals, synced with attendance such that approved leaves are reflected automatically.
  • Mar 2022 - Aug 2022 Project
    Smart Suit: Developed an IoT device and web application to enhance coal miner safety for Smart India Hackathon 2022.

Project Intern @ Mallow Technologies

  • Feb 2023 - May 2023 Project
    Traced and fixed a backend logic bug in the GIST CRM chat module that caused incorrect customer and message counts in production, restoring data accuracy across chat workflows.

Junior Software Engineer @ LTRC, IIIT - Hyderabad

  • Sep 2023 - Jul 2024 Project
    Web Development: Designed and developed websites for LTRC events, including IASNLP and PLO, as well as course pages, supporting event outreach and academic learning.
  • Sep 2023 - Feb 2024 Project
    Tamil Syntactic Parser: Fine-tuned the Trankit framework on an in-house annotated Tamil data to build an AI-powered Tamil syntactic parser that decomposes complex sentences and maps word relationships for Tamil language research which is presented at the Kani Tamil 2024 conference.
  • Dec 17, 2023 Publication
    Disfluency Identification for Indian Languages using Transformer-based Models: Trained a model to detect and classify disfluencies in text, presented at ICON 2023
  • Jun 21, 2024 Publication
    Medical Visual Question Answering with Vision-Language Models: Our work for the MEDIQA-M3G 2024 shared task uses a fine-tuned ViLT model for clinical dermatology VQA, ranking 6th on the leaderboard. Post-challenge, we trained on more data and explored large VLMs such as Gemini and LLaVA.

MS by Research Student @ IIIT - Hyderabad

  • Aug 2024 - Present Research
    Researcher @ LTRC, IIIT - Hyderabad
    Enrolled in MS by Research at IIIT-Hyderabad, working on Medical NLP research and building practical applications in the field.
  • Aug 2024 - Dec 2025 Project
    MediHelp AI (for CMC Vellore Doctors)
    • Built a real-time collaborative, multi-format document editor (Tiptap, WebSockets) and moved heavy operations to asynchronous queues (BullMQ) for better performance and reliability under load, reducing manual document work by ~60%.
    • Integrated LLM-powered translation, Q&A, summarization, and text-to-table features to support doctors' report writing.
    • Deployed the application using Docker and set up a CI/CD pipeline with GitHub Actions that deploys to AWS (EC2) for staging and CMC's internal infrastructure for production.
  • May 4, 2025 Publication
    SpanSense - Perspective-specific span identification and Summarization
    Second Workshop on Patient-Oriented Language Processing (CL4Health), NAACL 2025
    • Secured 6th place on the official PerAnsSumm 2025 leaderboard with an overall score of 49% for perspective-aware medical CQA summarization.
    • Designed a RoBERTa-large + BART-large pipeline for perspective span classification and summarization, achieving 90% Macro-F1, 92% Weighted-F1, and 84% BERTScore.
  • May 2025 - Sep 2026 Project
    Structured Radiology Intelligence (SRI):
    • Improved clinical data standardization for rectal cancer MRI reports by fine-tuning LLaMA 3.1 8B Instruct for structured information extraction and building a curated domain-specific dataset using multiple LLMs.
    • Developed a web application for dataset annotation, validation, quality control, and demo, and deployed the fine-tuned LLM as a scalable inference service with guardrails for reliable structured MRI report processing.
  • May 2026 Publication
    Structured Radiology Intelligence: Extracting structured data from MRI Reports using LLMs
    Third Workshop on Patient-Oriented Language Processing (CL4Health), LREC 2026
    • Achieved an 87.36% composite score and 18.42% performance improvement using LLaMA 3.1 8B Instruct for automated MRI report structuring.
    • Developed and benchmarked a 55-variable clinical dataset, evaluating LLaMA, Qwen, and DeepSeek through prompt-tuned and fine-tuned LLM pipelines.

Full-Stack Developer @ Rubrix.ai

  • May 2026 - Present Research Project Internship
    • Developed an AI-powered semantic recommendation system that matches online resources to course content and created a database of resources with precomputed similarity scores, surfacing matches at ≥ 0.85 similarity. It replaced a paid Perplexity API workflow, saving ~₹10K/month.
    • Implemented code and text plagiarism detection for student submissions, triggered automatically by a Celery worker after every submission, replacing manual integrity checks.
    • Built an automated question paper generation feature that lets instructors define templates such as sections, marks per question, units covered, number of sets, and AI-generated vs. previous-year question ratios, eliminating manual assembly and reducing API costs by ~50%.
