Lumira- when safety is designed, not improvised
Lumira is a rose-gold bracelet that looks like jewelry but contains GPS, a SIM, and a hidden button- one press sends your live location to trusted contacts and calls 112, no phone needed. We would love feedback on how to validate hardware demand pre-launch.

Certi4Safety - we dont guess we measure every architecture decision
Certi4Safety automatically audits automotive software projects against Regulations — telling you per requirement what's met, what's partial, and what's missing. Unlike yet another AI wrapper, every architectural decision is Six-Sigma-proven: we measured instead of guessed across three designed experiments. The data is clear — the LLM drives 32% of quality variance while the embedding barely matters, and prompt-caching cuts cost by ~70%. That gives us a defensible $0.09-per-process price point for the SaaS model, plus a fully local $0 judge for on-prem and edge deployments.

Job Tracker Application
A job tracker that allows the user to track and apply to jobs using a kanban board. Features allow user to apply in DACH region easier. Working on setting up and implementing the first few key features. Reason was reaching limits on competitor sites and feeling like with claude code I could implement something comparable that met more niche requirements.

AI-based Assessment of Cyber Security documents
Today I developed an AI-based solution that performs document assessments on cybersecurity process documents, which are essential for successfully passing Cybersecurity Certification Audits. Our tool analyzes the documents and generates a detailed, easy-to-read audit report. I have also verified the results manually, and they are highly accurate. However, the main benefit is efficiency: it performs document assessments over 30 times faster than a manual review, while providing much greater detail.

Recursive Feedback
Recursive build: a Todo app with a built-in Claude Haiku feedback bot. End-users chat their feature wishes, the bot asks business clarifications, then writes a Spec-Kit-style GitHub Issue back into the same repo. Non-tech users produce implementation-ready specs.

EnergyIQ — AI-Powered Electricity Price Forecasting for German Manufacturers
I built a live electricity price forecasting system for the German market using machine learning and real ENTSO-E market data. Tonight I connected the model to live APIs to generate tomorrow’s electricity price forecast in real time, and I’d love feedback on product positioning, customer validation, and how useful this would actually be for industrial energy operators and CHP users.

Building Tech Riders That Venues Actually Understand
Technical Rider Builder lets musicians create and maintain the technical rider they send to venues — stage needs like monitoring, FOH audio, input list, lighting, RF, and stage plot. Instead of hand-editing PDFs before every gig, artists build the rider section by section and export a clean, professionally formatted PDF.
