Ansh Mishra is a software engineer and backend developer who engineers production systems that don't fall over payment ledgers that balance to the cent, APIs that scale under concurrent load, and AI tools that make developers faster. Currently shipping at Alter Dimensions, previously at Aeonian Devs.

Backend Systems

Atomic wallet ledgers, multi-tier inventory with checkout holds, and 170-endpoint APIs on TypeScript + Prisma.

AI Developer Tools

RAG pipelines with AST chunking, 768-dim vector search, and sub-10s answers over entire codebases.

Cloud Infrastructure

Multi-env AWS Elastic Beanstalk deploys, Docker containers, Redis/BullMQ job queues, CI/CD pipelines.

Where I've shipped

Software Engineer

Alter Dimensions gobeet.app

Jun 2025 — Present
  • Engineered Stripe Connect payments, webhooks, and an atomic wallet ledger with a ~10% platform fee for reliable paid ticketing and auditable host payouts.
  • Implemented multi-tier ticket inventory with 5-minute checkout holds and 2-minute reclaim jobs to eliminate oversell risk during concurrent purchases.
  • Built a ~170-endpoint TypeScript/Prisma API (47 models) with Firebase auth, RSA QR check-in, FCM, and multi-env AWS Elastic Beanstalk deploys.

Things I've built

01

RepoMind

AI Code Intelligence Platform

A TypeScript monorepo answering questions about any codebase in under 10 seconds. AST chunking, Groq-powered RAG with SSE streaming, and sub-3-minute indexing for 10k-line repos.

  • GitHub/ZIP ingestion via Redis/BullMQ → 768-dim Upstash + Postgres
  • Live SSE progress, rate limits & embedding fallbacks on free tier
  • 3-panel workspace: chat, Monaco file:line citations, React Flow graph

ThinkBoard

Real-Time Collaborative Workspace

A dual-pane workspace unifying Editor.js documents and Excalidraw diagrams in three layout modes — Document, Canvas, and Split — built on Next.js 15 and React 19.

  • Convex-backed saves for document & canvas JSON in ~0.6–0.8s
  • Team file CRUD, archive/restore, and a 10-file free tier
  • Fixed Excalidraw SSR & Editor.js remount leaks — 18/18 tests green, ~1.8s dashboard load
