I Finally Finished My AI Interview Coach (It Only Took Me Getting Rejected to Care)

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built An AI interview coach that runs in your browser. No backend. No accounts. No subscriptions. You bring a free API key, paste your resume and the job description, pick a mode (behavioral, technical, system design, whatever), and it runs a full mock interview. Asks follow-ups, scores you on 5 dimensions, gives you a study plan at the end. I built the first version for the Gemma 4 DEV.to Challenge last month. It kinda worked. But I wouldn't have used it myself, and that bothered me. Live: hajirufai.github.io/gemma4-interview-coach Repo: github.com/hajirufai/gemma4-interview-coach Demo What you get now: 🗣️ 6 practice modes — behavioral (STAR method), technical, system design, online assessment sim, certification prep, case studies 🎤 Voice mode — talk into your mic, hear feedback read aloud. Because typing answers in a mock interview is weird. - 📄 Resume + JD aware — paste both, get questions about your actual experience gaps 📸 Screenshot upload — snap a coding problem or whiteboard and discuss it 🌐 4 AI providers with free tiers (Google AI Studio, OpenRouter, NVIDIA NIM, Hugging Face) 🌙 Dark mode, session history, timer, downloadable reports ## The Comeback Story ### Where it was before I threw this together during the Gemma 4 Challenge in May. Classic hackathon energy — built the core chat loop, got 6 mode cards looking nice, slapped on dark mode, shipped it. Then I hit the wall. Google AI Studio was throwing 500 errors during peak hours. The only option was "refresh and hope." No voice input, so you're typing interview answers like it's a customer support chat. And if you had a typo in your API key? Good luck figuring out why nothing's working. It was a demo, not a tool. ### What actually changed I came back with one rule: make this something I'd actually use to prep for my own interview. Voice mode was the big one. I'm prepping for a senior cybersecurity engineering interview right now. Typing

I Revived Wrisha — the Emotional AI Companion I Left for Dead"

What is Wrisha? Wrisha is a desktop emotional AI companion — an animated character who can see you, hear you, talk back, and react. The pipeline is genuinely multimodal: Vision — webcam + facial-emotion detection (OpenCV / FER) Hearing — speech-to-text so you can just talk to her Brain — an LLM generates her replies, in-character Voice — text-to-speech with mood-modulated tone Avatar — an animated face (pygame) that emotes and lip-syncs I built the bones of it a while back, got busy, and walked away. The Finish-Up-A-Thon was the push I needed to come back to it. The "before": it didn't just need polish — it was dead When I reopened the repo, the harsh truth was that the app couldn't even start. Two things had rotted: The environment was a fossil. The project was so old it wouldn't install on a modern machine. Wrong numpy, stale dependency pins, and a Python version mismatch that sent pip trying to compile packages from source and failing. Just getting it to attempt to run took a full environment rebuild on Python 3.12. The code was half-migrated and crashed on launch. I'd previously upgraded the internal modules — memory, a mood engine, a smarter brain — to a "v3" design, but I never finished wiring them into main.py. So the moment it tried to start, it died: TypeError: init () missing 2 required positional arguments: 'memory' and 'mood_engine' The "before" in one screenshot: a project that built its best features and then never connected them. I'd built the hard parts — persistent memory, a smooth mood state machine, proactive behavior — and left them sitting in files that main.py never even imported. Classic abandoned-side-project energy. The "after": three things I finished I set out to do three things, and I'm counting all three as the win. It runs again The core fix was finishing the migration: rewiring main.py to actually construct the Memory and MoodEngine, inject them into the Brain, and reference mood from the engine instead of the dead attribute it used to
