KKOS / KUMAR KAUSHIK’S WORKBENCH

Turning ambiguity into
working systems.

I build software and SaaS products — from the first workable idea to the details that keep it useful.

Applications. Systems. Full-stack delivery.
OPEN A FILE. SEE HOW I THINK.

01 / Video & discovery

ReeloGram

A home for the things worth watching.

Discover a video, make it your own collection, or share something you made. A complete journey from the first upload to the next watch.

  • Next.js
  • TypeScript
  • MongoDB
  • NextAuth

Make ownership a rule, not just a hidden button.

02 / Full-stack & data integrity

Transaction Ledger

Every entry has a consequence.

An account workspace for credits, debits, and transfers — with exact balances and a clear transaction history. Useful on the surface. Careful underneath.

  • React
  • Express
  • PostgreSQL

A transfer succeeds together, or not at all.

03 / Real-time file sharing

File2File

One file. Two browsers. A deliberate handoff.

Send a file between two browsers using a temporary link and a separately shared PIN. Clear transfer progress and verified completion make the handoff understandable.

  • Next.js
  • TypeScript
  • React
  • WebRTC

04 / Mobile & interaction

Zen Mahjong

A small game. A considered system.

A calm Mahjong Solitaire prototype with a separate game engine and local progress. Built to explore how a thoughtful interface supports real domain logic.

  • React Native
  • Expo
  • TypeScript
  • MMKV

Real workflows. Shared responsibility.
The details that keep products useful.

Building AI-enabled application features across the interface and backend.

AI-enabled product features
