TUSHARGEETEY

I like building software that makes complicated things feel simple.

Sometimes that means production systems. Sometimes it means building the tool I wish already existed.

Software engineer with 5+ years across Microsoft, Amazon, Oracle and product teams.

Now building independent products and developer tools.

Selected Work

Products and developer tools I’ve designed, built and shipped independently since February 2026 — a live consumer app, a native macOS utility and developer tools for working with AI agents.

01 / 05Prototype · 2026

Kelson

A multiplayer workspace where engineering teams and AI agents build software together.

A shared project canvas, live agent runs against a real GitHub repository, and human checkpoints before risky changes land — with team memory that carries across runs.

Next.js / React · Supabase · RLS · Realtime · Octokit · Gemini / OpenAI · MCP

Open live prototype(opens in a new tab)
02 / 05Private prototype

ApplyPilot

Job applications with a human at the end: it ranks, fills and drafts — you submit.

A Python pipeline discovers roles across ATS sources and ranks them against the candidate profile; a Chrome extension fills each form with grounded answers and stops at the submit button.

Python · Playwright · Chrome MV3 · GitHub Actions · LLM cascade

PIKY

A native Mac shortcut: grab text, screenshots and files from any app, send them to AI in one keystroke.

Option-Space captures a selection, a screen region or Finder files in any app; Command-Return hands the whole stack to the AI tool you’re typing into — locally, with no account, model calls or uploads.

Swift · AppKit · Accessibility APIs · NSPasteboard · ScreenCaptureKit

Context Runtime

Local-first, owner-reviewed context that carries a project across Claude Code and Codex.

Tools can suggest context; only the owner approves it. Approved state updates atomically with conflict protection and restart recovery, then reaches each coding tool over MCP.

Python · MCP (FastMCP) · Pydantic · SQLite FTS5 · PyInstaller

02 / Experience · Sep 2020 — present

Five years in production. Now independent.

Security and platform modernization, workflow engines, payments, seller verification and banking infrastructure — the same problems of state and reliability, at very different scales.

  1. Independent Work

    Feb 2026 — Present

    Building and testing products across AI-native developer workflows, automation, native macOS tooling and consumer software — owning the path from problem framing and architecture through implementation, validation and release.

Rigorous underneath, simple on top.

I've spent 5+ years building production software at Oracle, Amazon, Booking.com, DataFlow and Microsoft — banking platforms, seller verification, payments, document workflows and family-safety systems.

Since February 2026 I've been applying the same instincts to independent products and developer tools — and shipping them.

I care about systems that are rigorous underneath and straightforward to use.

How I build now

Co-building tools — Claude Code · OpenAI Codex · GitHub Copilot · Gemini / Antigravity

AI is part of how I build — architecture exploration, implementation, refactoring, debugging, codebase analysis and tests. The architecture, the review, the correctness and the final technical calls stay mine.

  1. 01

    Context discipline

    Tools get clean, verified local context and real schemas — not guesses.

  2. 02

    Implementation velocity

    AI speeds up scaffolding, tests and multi-file refactors across a codebase.

  3. 03

    Human checkpoints

    Architecture trade-offs, state changes and edge cases are reviewed by me before they ship.
