full-stack & systems engineer
being an account of graph-structured knowledge systems, terminal-native tooling, supply-chain security
I build systems where the structure is the point — knowledge graphs with tens of thousands of nodes, dependency trees you can trace a compromise through, terminal tools that stay out of the way. Most of my work sits between a database and an interface, making large, tangled data navigable.
Currently a full-stack engineer at Chandigarh University's Lucknow campus, working on CMS architecture and a Neo4j knowledge graph over 20,000+ publications and patents. Before that I shipped a cross-platform desktop product at Notely on Electron and a microservices backend. On the side I write Rust CLIs and read a lot of lockfiles.

A terminal-native workflow engine. One pluggable abstraction over OpenAI, Gemini, Claude and Ollama with bring-your-own-key auto-detection, a multi-pane Ratatui interface, and an extensible command system for scripting AI tasks.

Maps npm and PyPI packages, versions and maintainers into a graph (HydraDB / OpenCypher), then answers the incident question: a package just turned malicious — which of my services are hit, how badly, and through what path. Blast-radius BFS, attack-path search, typosquat detection.

The backend for a desktop overlay assistant: it watches the active window and clipboard, collects and ranks on-screen context, resolves intent, and answers through OpenAI with a persistent memory layer — streamed over WebSockets.

Turns CCTV video into crowd-flow intelligence — density, direction, congestion and counter-flow anomalies — to flag crowd-crush conditions before they build, instead of just counting heads. Operator console over a computer-vision pipeline.

A video-conferencing app built to learn WebRTC from the wire up: a signaling server, STUN traversal, and direct peer connections carrying the media — no SFU or media server in the path.

What a deploy platform does under the hood, rebuilt as three services — an upload service, a build/deploy worker, and a request handler that routes each request to the right build — wired with Redis, AWS and S3.

A Turborepo monorepo: authenticated real-time drawing over WebSockets with Postgres/Prisma persistence — front end, back end and shared packages in one graph, containerised with Docker.
TypeScript · Turborepo · Canvas · WebSockets · Prisma
A collaborative kanban board where every client stays in sync through a single WebSocket server broadcasting issue moves. Built on Bun, no database — the board state lives in memory.

A fully on-chain NFT marketplace on Solana with IPFS/Pinata storage, Ceramic profiles and multi-wallet support — minting, listing and trading with no central backend holding the data.

What changes when institutional research stops being rows in a table and starts being nodes and edges.
Building ChainTrace meant answering one question fast: if this dependency is bad, what breaks?
Terrek talks to OpenAI, Gemini, Claude and Ollama through one interface. The abstraction layer is the whole design.
SVG gave up around 800 nodes. Here's what moving the knowledge graph to canvas actually involved.
Hand-bound with Next.js and three.js. Set in Fell’s English and Garamond. The binding is a 17th-century octavo; the leaves turn as you read down the page.
The town through the study window, and every plate in these leaves, is Heidelberg as Matthäus Merian engraved it in 1620 — public domain, re-inked for dusk.
