Intavue
An AI interview-prep platform with a real-time voice interviewer that reads your resume and asks live follow-ups — plus a code-grading sandbox and a multi-agent AI coach. Architected and built solo, end to end: web app, Windows and macOS desktop apps, billing included.
- 01
Keeping voice latency low enough that a live AI interviewer feels conversational — while it's simultaneously reading a resume and reasoning about follow-ups.
- 02
Running and grading untrusted user code in four languages (JavaScript, Python, Java, C++) safely, on approach and edge cases rather than just output.
- 03
Making three distinct AI systems — interviewer, coach, and code grader — feel like one cohesive product across web, Windows, and macOS.
- 04
Operating a paid product solo: billing, credit metering, and production incidents all land on the same person who wrote the code.
- ✓
A streamed, latency-budgeted voice pipeline: each stage (speech-to-text, reasoning, speech synthesis) gets a budget, and responses stream so the interviewer starts speaking while still thinking.
- ✓
A sandboxed code-execution service with per-language runners and rubric-based grading that evaluates the approach and edge-case handling, not just stdout.
- ✓
A shared design system and one product core with thin platform shells, so web and the desktop apps ship from the same brain.
- ✓
Credit metering wired into every AI feature from day one, so unit economics are measured per request instead of discovered on the invoice.
Live in production at intavue.app on a free tier and a $15/mo Pro plan.
Shipped across three platforms — web, Windows, and macOS — by one engineer.
Live code grading in four languages with rubric-based scoring.
The complete SaaS spine — auth, subscriptions, credit metering — built and operated solo.

Keyhold
A UK property marketplace for renting long-stay homes or buying — with an AI assistant that compares listings and starts the enquiry in chat. Every part of the public site is editable from the dashboard: colours, fonts, page layouts, legal copy, coverage, even the assistant's own personality. Architected and built solo, end to end.
EmpfehlerWerk — Referral Marketing Platform
A German platform that turns customer recommendations into automated referral programs — personalized referral pages on custom domains, tracked conversions, and automatic rewards. I worked on the frontend and the analytics dashboard. Selected details are withheld under NDA.
