PM Approach

Product work moves faster with AI built into the workflow.

From first signal to shipped product, AI is the core reasoning and automation layer.

Maddox AI replaces manual and rule-based visual inspection with AI-based visual quality control that is automated, accurate, and robust. Leading manufacturers in automotive, electronics, and industrial production use the platform to train, evaluate, and deploy their own inspection models without requiring technical ML expertise. Beyond detecting defects, it alerts teams to rising error rates and helps prevent quality issues before they scale. As Head of Product, I owned the roadmap and full product lifecycle from discovery through execution to delivery. Led a cross-functional team across product, design, engineering, and ML. Focused product craft on impact, usability, and scalability.

The authentic patient voice is scattered across millions of social posts, forums, and publications in different languages, and largely invisible to pharma. Semalytix analyzes these unstructured data sources at scale with AI and NLP across dozens of therapy areas and languages. Leading pharma companies use the platform to uncover treatment burden, symptom patterns, and competitive intelligence at speed. As Product Manager, I owned the full product lifecycle from early concept to enterprise rollout and scale. Led a cross-functional team across product, design, engineering, and ML. Co-authored the paper that won EphMRA's 2020 Future Leaders Award.

Beckhoff implements open automation systems using PC-based control technology. The product range spans industrial PCs, I/O and fieldbus components, drive technology, automation software, control cabinet-free automation, and hardware for machine vision. Beckhoff's automation systems run semiconductor fabs, logistics robots, and intelligent buildings, scaling from 100 µs control cycles to machines with hundreds of coordinated axes. As Product Manager for automation software, I drove feature delivery across the platform, led discovery with key accounts, introduced structured QA workflows, and represented the company and its products at international trade fairs.

Education

Engineering foundation, business extension.

A business administration master’s built for engineers and natural scientists — training problem-solving at the intersection of technology and business, the same intersection where product management lives. Focus on entrepreneurship, digital business models, leadership, planning, and decision-making. In my thesis, I evaluated neural network architectures for business decision-making and implemented recurrent neural networks in Python/TensorFlow to forecast economic time series such as company sales.

A work-integrated engineering bachelor’s combining university study with hands-on product development at Beckhoff Automation — automating high-tech machines, robots, and production lines while covering computer science, electronics, and mechatronic systems. Building real technology from day one, not just studying it. In my thesis, I evaluated safety systems and their error-handling, then designed and implemented a software tool that diagnoses faults automatically to minimize machine downtime.

Projects

Built with AI.

A personal portfolio website with an AI chat that answers questions about my background from my CV, expandable cards for experience, education, and projects, and a CV request form with email approval. Written in TypeScript on Next.js 16, React 19, and Tailwind CSS v4. Server routes stream Claude API responses over SSE under per-IP rate limiting, with HMAC-signed CV requests sent through Resend, cookieless PostHog analytics, and a strict Content Security Policy. Playwright end-to-end tests, deployed on Vercel.

A browser extension that analyzes job postings in real time while browsing. Content scripts on the major job boards extract each posting, Claude scores it against the user's CV and returns green and red flags, and Firecrawl pulls ratings from employer review platforms in parallel, all rendered in a sidebar. Written in TypeScript and React on Vite, packaged as a Chrome Manifest V3 extension. CVs are parsed locally with pdf.js, results are cached per URL for 24 hours, and a Safari build ships through the web extension converter.

A baby monitor that runs in the mobile browser, with no app install or account. One phone opens the camera view, the other the parent view, and a room code pairs them over WebRTC. Written in vanilla JavaScript with no framework or bundler, styled with Tailwind CSS. Ably handles signaling, STUN and TURN servers handle NAT traversal, and connection statistics drive silent reconnects and a degraded mode that pauses video to keep audio flowing. The parent screen stays awake through the Wake Lock API. Hosted on Vercel.

A watchOS-first scoring app for tennis and padel with a minimal iOS companion. Scoring runs through an event-sourced engine with a pure reducer, so every match can be replayed and any point undone. Written in Swift 6 with strict concurrency and SwiftUI on both targets, persisted in SwiftData over the CloudKit private database, with WatchConnectivity for low-latency live updates and HealthKit workout sessions for heart rate and calories. Bilingual from day one, with no third-party SDKs.
