001 / About

Ankit Kumar

I'm a final-year computer science student who got curious about what actually happens under an API — and kept digging until I hit allocators. The projects that followed run the whole depth of the stack: a C++26 storage engine that starts at NUMA-aware memory management, a Redis-compatible server built on a single event loop, and a booking platform whose architecture was written as ten numbered documents before the first commit.

The throughline is measured performance. Claims on this site come with the benchmark, the bound, or the sanitizer run that backs them — and where something is still in progress, it says so.

Away from the terminal: competitive programming (Codeforces Expert) and chess.

Real-time infrastructure, in production

ControlShift Talent

Engineering Intern

Feb — May 2025

Built the real-time backbone of a live AI interviewing platform — the infrastructure between a candidate on video and the AI on the other end.

  • Architected WebRTC signaling and a WebSocket layer with heartbeat, room management, and reconnection for candidate–AI video sessions
  • Built a collaborative code editor over WebSocket, syncing client state live during interviews
  • Moved blocking email I/O to BullMQ + Redis job queues with retry and dead-letter handling
  • Chunked live interview recordings into an async cheat-detection AI pipeline
  • Shipped 30+ REST endpoints with input validation and centralized error handling, backed by 25+ unit tests on auth and booking paths
