Overview

An AI interviewer that talks to candidates in real time (OpenAI Realtime over WebRTC) and, for engineering roles, runs a live coding round. Questions and JDs are generated offline with Gemini.

My part: the coding round — a Monaco editor with per-language persistence, and a Judge0 execution layer that runs submissions against sample and hidden test cases and scores by pass rate (Daytona sandboxes as an alternative provider).

Previous Project

3D Wall Decor

A real-time 3D wall-visualization tool: a wall photo plus drawn measurements become a Blender 3D model and an itemized bill of materials. I contributed specific improvements to an existing system.

Next Project

UPSCash

Cash-reconciliation automation for a US department-store chain — matches each store's end-of-day register cash against QuickBooks and flags the discrepancies that matter. Built in about two weeks.
