Sixteen years, six employers, one throughline

I build the parts of retail software that auditors care about. Fiscalisation integrations across several countries, and one licensing system meant to replace every product-specific implementation in the portfolio instead of becoming the next one.

What I did

• Designed and implemented a centralised licensing system for the whole product landscape
• Built multi-country fiscalisation integrations for POS cash registers
• Collaborates on architecture workshops and mentors developers while staying on core POS delivery

Freelance technical writer for draft.dev since 10/2024.

Five developers, one platform that could not stop shipping. We restructured the core architecture while delivery kept moving, automated the release path and cut deployment time by 40%. Code quality went from opinion to pipeline rule through static analysis and shared lint gates.

What I did

• Redesigned the core product architecture together with the development lead
• Built the deployment automation that cut release work by 40%
• Introduced static analysis and lint rules as repo-wide quality gates
• Led a team of five and mentored developers into new technical areas

Tourism portals for German clients, where the map was the product. The Leaflet and Vue mapping application I wrote became the default on every tourism site the company shipped afterwards — one implementation instead of one per contract. I ran the Brandenburg portal and its regional subsites end to end, built the first SaaS prototype for the cleantech energy-community product enixi, and was the only developer and main contact for the Bitmovin landing page.

What I did

• Built the reusable Leaflet/Vue mapping plugin adopted by 100% of company tourism sites
• Primary developer and customer contact for the Brandenburg tourism portal used by thousands of visitors
• First working prototype of the enixi cleantech energy-community SaaS
• Sole developer and main contact for the Bitmovin landing page, on Next.js and Contentful

Part-time (20 h/week) from 04/2019 to 04/2020 while serving as Development Lead at Agitron d.o.o.

Electronic price tags that reprice themselves when the weather changes and double as indoor-navigation beacons. I redesigned the architecture, hired the team and we shipped a working prototype: backend, dynamic pricing logic reacting to external factors, and the custom hardware partner kept in the loop. Part-time on paper; in practice I sometimes slept in the office, which is why it lasted exactly one year.

What I did

• Redesigned the architecture of the e-ink price tag platform and led its prototype
• Dynamic pricing logic reacting to external factors such as weather and local events
• Hired and led the development team; mentored every new developer
• Joined the CEO in customer presentations and represented the company at conferences

Part-time, in parallel with reduced hours at Pixelpoint.

Agitron was the spin-off built on the customer-tracking prototype I had written at Anolis, so after I moved to Austria the owners kept calling. For three years I advised them on architecture and technology-stack decisions and sat in on hiring — freelance, and light enough to fit around a full-time job.

What I did

• Advised leadership on architecture and technology-stack choices, improving scalability and maintainability
• Assessed and evaluated candidates for the development team

Stack

Freelance alongside the full-time role at Pixelpoint.

Print ordering used to be a phone call and a spreadsheet. I built the customer-facing upload and ordering site, wrote the price calculation from scratch, and wired accepted orders straight into the production pipeline — 50% more throughput without more people.

What I did

• End-to-end web-to-print automation: upload, pricing, production handoff, status updates
• Order-to-shipping productivity up 50%
• Custom PHP and C# CMS platforms, plus a single-page radio site that never interrupts playback
• Team lead and developer on Škoda campaign microsites

Freelance web development for CarPro s.p. from 10/2013 to 06/2016.

My first job was making other people’s research run faster. A forest-growth simulation that took weeks per run ran in days once I turned it into a distributed system — C++, CUDA and a lot of Qt.

What I did

• Redesigned the forest-growth simulation to run distributed: weeks to days
• Implemented the image classification system on Kohonen self-organising maps
• Teaching assistant for computer graphics and neural networks
