Yannick Herzog

I am a developer and consultant – and I don't separate them. When you work with me, you get both from a single source: someone who can make technical decisions and also implement them themselves.

I advise you on technology decisions, design the architecture, and then I write the code. If something doesn't work, I fix it myself. One point of contact for everything technical.

I work with founders, with startups that don't have a technical co-founder, and with teams that have developers but no one with a technical compass.

What I specifically do:

About my background: I've been developing web applications for 15 years. I was CTO of an AI startup in the education sector. And I founded a B2B SaaS myself – ajonta.com – which is running productively today. So I know both sides: that of the developer and that of the founder.

This is how we start:

1. You write me your situation

2. We talk for 30 minutes

3. I'll honestly tell you if and how I can help

------------

I work independently of technology, but with a clear preference for modern, scalable web stacks. On the frontend, my focus is on component-based development with Vue.js and Nuxt – for performant SPAs and SSR applications with clear structure and high maintainability. For framework-independent projects, I rely on Web Components, which I implement with Lit – lightweight, standard-compliant, and ideal for reusable UI elements.

My work follows the principles of Clean Code, a consistent separation of logic and presentation, and adherence to established conventions in HTML, CSS, and JavaScript.

I place great value on well-thought-out architecture, clean, maintainable code, and transparent processes – from technical conception to tested, production-ready application.
