I've been selected for Google Summer of Code 2026 with the UN - OICT, contributing to the FireForm project. I've also won four hackathons Smart India Hackathon 2025, HackVerse 5.0 at NITK Surathkal, GENESYS at PES University, and CodeFury v7 at UVCE. I've also been selected as a recipient of the 2025 Shubhra Kar Linux Foundation LiFT Scholarship.
Currently at Oldowan Innovations, I build backend services with Python, FastAPI, and Django, and also handle complete cloud infrastructure keeping deployments smooth across staging and production.
Worked as a Flutter developer intern at MedCortico and freelanced at VSIX, building cross-platform apps and scalable mobile solutions.
I'm a member of Point Blank, a student-driven coding community that runs contests, CTFs, and technical events to grow the programming culture on campus. I was a core organiser of Aventus 3.0 where I led all technical operations the hackathon.

Maintainer
·FireForm (UN-OICT)Sep 2026 - Present · 3 months- Joined FireForm through UN-OICT as a Google Summer of Code 2026 contributor, owning the backend from the v1 API contract to the extraction pipeline, and became a maintainer in September 2026.
- Review and merge contributor pull requests across the backend.
- Triage issues and help new contributors get their changes merged.
- Keep developing the backend I built during the program: the v1 API contract, the PostgreSQL platform and the pluggable LLM provider layer.
- Take part in technical planning and releases with the other maintainers.

Open Source Contributor (GSoC)
·Google summer of code 26' - UN-OICTMar 2026 - Aug 2026 · 6 months- Proposed FireForm's codebase architecture in core technical discussions: split the monolith into two repositories, defined the layered backend package, the per-environment Docker setup and the API versioning strategy, all adopted by UN-OICT maintainers. Shipped 56 pull requests across 58 issues, second highest contributor on the project.
- Wrote the v1 OpenAPI contract before implementation, agreed with maintainers, with Pydantic models generated from the YAML spec.
- Built the extraction pipeline and form generation on a shared incident schema, running on a local model so incident data never leaves the department.
- Added a pluggable LLM provider layer for extraction, so OpenAI, Gemini, Claude or self-hosted Ollama swap in through config.
- Migrated SQLite to PostgreSQL with maintainers to handle concurrent writes across gunicorn workers, added Alembic migrations and a Celery + Redis job pipeline, and cut Docker dev startup from around 2 minutes to 3 seconds with BuildKit cache mounts.
