Full experience

• Built a real-time voice negotiation simulator so Sales Management students can practise against a counterparty that holds a position, instead of role-playing with classmates.
• Low-latency pipeline: streaming audio, speech-to-text, an OpenAI-backed counterparty with dialogue state across turns, adaptive text-to-speech back out.
• Added the tracking that makes practice legible: user insights, negotiation analytics and performance records over a term.
• Reworked the architecture for concurrent sessions so the platform could expand into further courses, and worked with enterprise partners on corporate deployment.

• Node.js
• TypeScript
• OpenAI APIs
• Vapi STT/TTS
• Streaming audio

• Led the rebuild of the property websites on Next.js, React, TypeScript and Tailwind, with Decap CMS so content changes stopped requiring a deploy.
• Shipped a booking engine, an online food ordering pipeline, and a Grillhütte reservation flow that previously ran on phone calls.
• Built an internal operations platform for scheduling, task tracking and employee lifecycle, on Node.js REST APIs and PostgreSQL with role based auth.
• Built an AI email and voice agent that handles bookings and answers common guest questions without going through the front desk.
• Improved page performance and SEO via server-side rendering, caching and asset loading, and brought the sites up to modern accessibility standards.

• Built mobile-first, responsive web applications in JavaScript (ES6+), React and Tailwind, integrating REST APIs and third-party services.
• Worked with marketing, architecture and business teams, from wireframes and prototypes through to shipped features.
• Troubleshot design and user-experience issues in production, and kept performance and usability consistent across the applications.

A training run keeps computing gradients for layers that stopped learning hours ago. EnAi watches gradient energy per layer while the run is in flight, freezes each layer the moment its contribution collapses, and raises the batch size into the headroom that frees up. All of it happens mid-run, with no restart and no change to the model code.

A small group building AI products around one question: what is still harder than it needs to be? Everything ships free and open source. The first product out is Admission OPS, because university admissions is one of the most paperwork heavy moments in a person's life and most of it is deadline tracking that software should have absorbed years ago.

A peer to peer video chat on WebRTC, handling signalling and connection state directly, with facial emotion inference running in the browser rather than on a server. The interesting constraint was frame sampling: infer too often and the call stutters, too rarely and the reading is stale.
