I teach voice AI to integrate with your existing platforms.
Fonio @ Hack Vienna 🏆
When a dental patient cancels at the last minute, the slot usually stays empty while a receptionist works through a paper waitlist by hand. Our agent, Alfred, notices the cancellation, ranks the patients who fit best, and calls down the list until someone takes the slot.
Zero One Hackathon 🏆
Spots when someone is about to abandon an insurance signup and steps in with a personalized nudge before they leave. Built for UNIQA at a 36-hour AI hackathon.
LPIS Ninja
At WU, popular courses fill up within seconds, and missing the window can cost you a semester. LPIS Ninja registers students automatically the moment registration opens. 200+ users, 400+ registrations, 98% success rate.
Raiffeisenbank International
Relationship managers at RBI had no single, credible ESG view to show customers. The data was spread across external providers and spreadsheets. The dashboard brings ESG scores for thousands of companies and bonds into one place, so every customer conversation starts from the same numbers.
Alfred
Alfred makes real phone calls for you. It books appointments and moves reservations, checks your Google Calendar mid-call, handles interruptions, and updates your calendar when it's done. Response latency stays under 1.2 seconds.
Nourish
Most calorie apps give you a fixed maintenance target that is rarely right and never changes. Nourish estimates your actual TDEE from your weight and intake data, so the target adjusts as you do.
Expertise
React & Next.js
My main frontend stack. I've built production apps with React and Next.js — from server components to complex client-side interactions. I know the trade-offs and can ship fast without cutting corners.
AI & LLMs
I've worked with large language models and can help you integrate AI meaningfully into your product — whether that's automating workflows, building AI-powered features, or making your operations more efficient.
Python
I use Python for backend logic, automation, and data pipelines. From scheduling engines to data processing, I can build reliable systems that run in production without babysitting.
