Kerala, India — most recently at Doctreen
Adithya S Nair
Freelance Full-Stack AI Engineer from Kerala, India. For the past two years I've been deep in medical AI — building the systems that read DICOM scans, reason over clinical data, and write structured radiology reports. I bring that same production rigour to every project I take on.

About Me
Most of what I do is make LLMs useful in production — not demo-useful, but actually-reliable useful. For close to two years that meant building and maintaining the AI core of a medical reporting platform at Doctreen, where the margin for error is low and the edge cases are everywhere.
The day-to-day involved LLM pipeline design, RAG workflows, and vision analysis for DICOM medical imaging across 10+ modalities. We used multiple providers — OpenAI, HuggingFace, Nebius, OVH — each with their own tradeoffs, and I've learned more about evaluation methodology than I expected when I started.
Separately, I spent 1.5 years running the ACM Student Chapter at Amritapuri as Chairperson — organising hackathons, mentoring students in AI / ML, and eventually coordinating the ICPC Asia West Regional Finals, which turned out to be a very different kind of systems problem.
I'm looking for what comes next — harder engineering problems, a different domain, or a role with more ownership. The quiet ambition is to keep building AI that delivers when it matters, and to grow into mentoring and leading engineering teams. If you've read this far and something looks interesting, I'm easy to reach.

Experience
AI Engineer @ Doctreen
Montpellier, France (Remote)
- ▹Built and maintained the AI features of a live medical report generation platform — integrating LLMs across multiple providers (OpenAI, HuggingFace, Nebius, OVH) with RAG pipelines and prompt engineering. Most of the hard problems turned out to be evaluation, not modelling.
- ▹Designed vision analysis pipelines for DICOM medical imaging across 10+ modalities, validated against radiologist ground-truth data to measure and close the accuracy gap.
- ▹Built internal tooling including a token-efficient serialisation format that meaningfully reduced API costs on high-volume inference runs.
- ▹Set up CI/CD pipelines and model monitoring so performance regressions surface before they reach production.
AI Research Intern @ Doctreen
Montpellier, France (Remote)
- ▹Joined at the foundational stage of the AI-assisted medical report system — the phase where you make architectural decisions you'll live with for years.
- ▹Built security guardrails and input validation against prompt injection and adversarial inputs; an underrated part of production LLM work.
- ▹Developed a multi-model benchmarking system to compare LLM performance across all pipeline stages, running evaluations in parallel to cut iteration time.

Projects
Vidyapath
LMS & School Management Platform for CBSE Schools
Full-stack multi-school LMS for CBSE Classes 10 & 12 with dedicated portals for admins, teachers, students, and parents — assignments, grading, attendance, gradebooks, and timetables in one platform. A multi-model AI routing layer (Groq, Gemini) powers AI-assisted assignment generation and question banking while keeping output pedagogically structured. Role-based auth via HMAC-signed JWTs over Supabase Postgres, with multi-school provisioning through a developer admin portal.
LensAI
AI-Powered Screen Region Explainer
Browser extension that lets users highlight any screen region — code, diagrams, articles, UI — and get instant, context-aware explanations powered by LLM integration. No more context-switching friction for developers and researchers.
Mitti Mitra
AI Soil Health Diagnostics for Farmers
Mobile app using computer vision and multi-source data fusion to help Indian farmers assess soil health and receive actionable crop recommendations. Designed the ML pipeline and integrated with a Flutter/Firebase frontend for field-ready deployment.
Namude Yatra
Multi-Agent Travel Planner
Multi-agent travel planner that generates full day-by-day itineraries through coordinated LLM agents using LangChain, with interactive map visualisations (Pydeck) and a chatbot interface for real-time trip adjustments.
