I build real-time systems and AI agents — software that earns trust.

I'm Ashutosh, a software engineer from Rajnandgaon, India. I care how a system is designed, how it scales, and how it behaves when things go wrong — right now, a real-time trading exchange and AI agents that get real work done.

Work

Orin

live in production2026

An AI app builder — an agent writes and runs your app in a cloud sandbox, streaming a live preview over SSE, with every step snapshotted to R2 so a dead sandbox resumes or rewinds (181 restorable checkpoints across 19 user-built apps), deployed on GKE.

Nebula

live in production2026

A perpetual-futures exchange built from scratch — single-writer in-memory matching engine benchmarked at ~200k orders/sec (p99 ~40µs over 1M orders), real-time order book over WebSockets, and deterministic snapshot/replay recovery, deployed on GKE.

Experience

Stealth Startup

software engineer (contract)2026 — present

Hardening a live, paid video-consultation app (React Native, Firebase, VideoSDK) — shipped 16 call-safety fixes, including a video-stream leak (~1,800 native streams per 15-min call → 1 per track), and moving call billing server-side with idempotent call start, credit holds, and a race-free booking lock.

Living on campus at 100xSchool’s six-month post-grad program in Noida, building production-grade systems full time — Nebula and Orin both shipped from here to a production Kubernetes deployment, on weekly build cycles with peer code review and system-design critique.
