I question before I build.
Before adopting a solution, I check whether it really fits the problem. That's how I came to shape 100+ UI building blocks of an in-house library that replaces a third-party framework – leaner and faster.
Konrad Thiemann
A software engineer who builds deliberately.
I build things that make people's lives easier – and in a way a team can build on: considered, lean, documented. I use frameworks and AI as a deliberate choice, not out of habit.
About me
Software engineer – currently working mainly in frontend, but not defined by it. I build software that makes people's lives easier, and I keep mature e-commerce systems running and evolving. I deliberately invest in good tools – including the way I use AI.
What matters to me
- Question rather than adopt
- Document rather than hoard knowledge
- Enable others
How I work
Show, don't claim – four principles.
I build purpose-fit, not bloated.
Lean, targeted solutions over universal heavyweights: fewer dependencies, clearer responsibilities, better performance.
Quality is built in – and lived.
Automated quality gates (lint → typecheck → test → build) and traceable commits – so a team can keep building fast and safely.
I enable others.
Apprentice, intern or team – I share knowledge instead of hoarding it. Including how to use AI sensibly in everyday development.
Sounds like a match?Let's talk
Tech stack
Tools and technologies I work with every day.
AI – deliberately built
I don't reach for AI at random – I deliberately define how it works: a system of specialised AI agents with clearly documented workflows. At work and in my own projects I steer the AI tooling through dedicated configuration files.
AI with high leverage, not blind trust.
What I own at work
For over 2.5 years I've worked on the frontend of a multi-brand e-commerce system. I look after not just the shop but the system around it – across eight subsystems. I think in connections, not isolated tasks.
- 2.5 yrson a production multi-brand shop
- 100+reusable UI building blocks shaped
- 9technical-SEO initiatives owned (2024–2026)
- 30+targeted performance improvements
- Shop plus a direct-order-pages variant
- Helped build a custom UI library that replaces a third-party framework
- API layer, shared libraries & drop-in packages
- Strapi CMS
- Technical SEO: automated sitemaps, meta data & Google Discover optimisation
- Noticeably faster load times through targeted performance work
