hi, that's me ↑

I build backends, break systems (on purpose), and sometimes make code sing.

Final-year CS undergrad into backend engineering, systems, and how intelligent things work under the hood. On the side, I turn algorithms into art and keystrokes into music.

about

I'm a final-year Computer Science undergrad who likes the unglamorous parts of software: the backends, the protocols, the systems that quietly hold everything up. Currently diving into AI and MCP — understanding how modern intelligent systems are actually built genuinely fascinates me.

I contribute to open source because it's the best classroom I've found. And when I'm not shipping, I'm usually making generative art or live-coding music — the same loops and functions, just pointed at beauty instead of throughput.

Women Engineers Scholar

Google × TalentSprint

Selected for the WE program by Google and TalentSprint.

Chosen as a Women Engineers scholar '24 — a two-year engineering excellence program by Google and TalentSprint with mentorship, rigorous coursework, and a community of women who build. That community later became WE4US, a platform I now contribute to.

Google Summer of Code — Contributor

UC OSPO · Brahma-XR

Helped take a WebXR research framework from private repo to public open source.

Brahma-XR is a framework for collaborative WebXR rooms with spatial data — the same code runs in the browser and on Apple Vision Pro, Meta Quest 3 and Varjo. As it moved from a private research repository to a public open-source project, I shaped the project structure, built the static documentation site, and created the routing system for running and showcasing examples — the foundation future contributors build on.

Code for GovTech — Contributor

ADC Karnal · Dedicated Mentoring Program

Built an Education Management Information System for a district administration.

Built an EMIS for the Additional Deputy Commissioner's office in Karnal under C4GT's Dedicated Mentoring Program '25 — daily attendance, marks and subject-level performance, rolled up so district administrators see schools, schools see classes, and teachers see individual students. Real users, real data, and downtime is not a vibe.

European Summer of Code — Contributor

pgmpy

Building the causal identification module in pgmpy.

Contributing to pgmpy, the Python library for probabilistic graphical models and causal inference, through European Summer of Code — working on the causal identification module: figuring out when and how a causal effect can be identified from observational data and a graph. Grew out of my earlier PRs to the library, now as its ESoC contributor.

SentinelForge

A privacy-first AI developer platform.

Ask questions about your documents and code and get answers with citations you can click through to the exact page or line. Give it a coding task and get a plan, the evidence, a unified diff, and real test output from a disposable copy of your repo — nothing is written until you press Approve.

LINER NOTES — WHAT I DID

Designed and built the whole platform in strictly-typed Python: local-first retrieval with on-device embeddings and a SQLite index, patch generation run in a sandbox, 12 MCP tools, Ollama support for fully offline use, and a 1,000+ test suite — all of it running in 512MB.

CodeMind

The repo that remembers.

A persistent memory graph for a codebase — it stores why the code is the way it is, watches new commits, and when someone unknowingly contradicts an established decision it forces a reconciliation: confirm the change is intentional, or catch the regression before it ships.

LINER NOTES — WHAT I DID

Built on Cognee Cloud for the WeMakeDevs hackathon — commit watching, contradiction detection against the memory graph, and the reconciliation flow where the memory itself can be wrong, get challenged, and correct itself, the way a real teammate's understanding would.

GoGitViz

Your true contribution graph, in the terminal.

GitHub's graph only counts what you push to GitHub. GoGitViz scans every local repository on your machine — private, offline, GitLab, all of it — and renders a colored GitHub-style heatmap of your real commit history, right in the terminal.

LINER NOTES — WHAT I DID

Written in Go: filesystem-wide repo discovery, commit indexing by author email, and a configurable six-month heatmap drawn with terminal colors. Built because my actual coding activity deserved a truthful picture.

WE4US

Community platform for the Women Engineers program.

An alumni-portal-cum-community-page for the Google × TalentSprint WE community — the program I was a scholar in — built around Lemmy with a React frontend and Phoenix services.

LINER NOTES — WHAT I DID

Contributor on the platform my own cohort uses: merged pull requests across the React/TypeScript frontend and the Lemmy integration — features, fixes, and plumbing.

This website

A portfolio disguised as an instrument.

The page you're on. A professional portfolio with a secret: the scroll bar is a playhead, the background is generative art, and the keyboard makes music when you let it.

LINER NOTES — WHAT I DID

Designed and built with Next.js and a hand-rolled WebAudio engine — no audio libraries. The background is a generative flow field, keystrokes play an FM e-piano, every project card gets a drum groove seeded by its own name, and blog posts settle Chladni sand figures. All copy lives in one JSON file; the score is live-codeable at /play.
