I'm Tarun. I've been writing React for about four years — long enough to have strong opinions about folder structure, short enough that every new Next.js release still feels exciting.
These days I work on a platform that lets enterprises run their own AI assistants. The kind of app where one bad render costs someone's afternoon, so I've learned to care about caching, re-renders, and the small decisions that compound across a hundred screens.
The web still feels like a playground if you let it.
On the side, I build end-to-end applications — including a RAG Knowledge Assistant, a Tool-Calling Research Agent, and a QR digital dining platform.

Stuff I've built lately.
A selection of my active applications, from AI-powered research and document search to digital dining.
2026 · Active project
RAG Knowledge Assistant
Ask questions across your own documents
A document question-answering app that accepts pasted text and uploads, extracts and chunks content, stores embeddings, retrieves relevant passages, and streams grounded answers through a separate API.
2026 · Active project
Tool-Calling Research Agent
An agent that searches, reads, and reports
A streaming research assistant that calls web-search and page-extraction tools, then returns findings in a chat interface. The app includes a separate API and persists conversations and messages.
2026 · Active project
Content Repurposing Tool
Turn source material into short-form scripts
An AI application that takes user-provided source text and generates hooks, short-form video scripts, and captions through a Next.js interface and an Express API.
2026 · Active project
QR Digital Dining
A guest ordering flow backed by a restaurant API
A multi-app QR dining project spanning a customer interface, staff dashboard, and NestJS API. The backend models restaurants, menus, dining sessions, and orders, with signed table access and staff authentication.
Path so far
A short version of the journey.
Four years at one company, three different roles, a lot of late nights.

Owning a big chunk of the Fluid GPT frontend — performance, multitenancy, and the move to on-prem deployments. Most days are equal parts code, code review, and arguing about state-management patterns.

01
Got the cloud app running fully on-prem so enterprise clients can host it inside their own networks.
02
Replaced ConfigCat with a custom tenant-level feature-flag system that reads from env vars at boot.
03
Migrated to RTK Query and watched API calls drop ~85% and page loads improve ~80% on the heavy modules.
04
Spent way too long getting the Playwright suite to run reliably on tenant-aware fixtures. Worth it.
