AI-driven mock interview app that simulates real interview experiences. Whether you’re prepping for a frontend role, data science, or system design, Prepster customizes the entire interview based on a short questionnaire, then runs a mock interview using a voice AI agent via Vapi. After each session, you get structured feedback and the option to retake it.

An interview-integrity platform that turns live behavioural signals — gaze, focus, screen state, paste events, object detection — into an explainable score and evidence-backed flags for a human reviewer, never an automated verdict. Live video runs over WebRTC with in-browser computer vision via MediaPipe, coding rounds execute in a locked-down sandbox, and every report is Ed25519-signed. A separate Python calibration lab enforces ethics invariants — absence is never evidence, a dismissed flag can only raise the score — backed by 167 passing tests.

A hand-rolled JSON REST API for movie data, written in idiomatic Go with no web framework — just net/http and httprouter. Ships with permission-based authorization, bearer-token auth with email-verified activation, per-client IP rate limiting, structured logging, live operational metrics via expvar, and graceful shutdown that drains in-flight background jobs before exiting.
