Description

Looking for more than just a ticket-taker, but an experienced partner who understands your technical vision and proactively implements it?

With over 20 years of experience in web development (the last 6 years specializing in React & modern frontend architecture), I help companies build scalable, performant, and maintainable applications.

🚀 How I can support you: I specialize in developing complex Single Page Applications (SPAs), SaaS platforms, and e-commerce solutions. My approach is "Product-First": I think beyond the code, keeping user experience and business goals in mind.

🛠 My Tech Stack & Expertise:

Frontend Core: React.js, TypeScript, Astro, HTML5, CSS3 (Tailwind, Bootstrap).

Architecture: Component Design, State Management, Performance Optimization.

Backend & Cloud: Integration of serverless architectures (Supabase, Firebase), PHP (Laravel), and SQL databases.

Quality Assurance: End-to-end testing (Cypress, Playwright) and unit testing (Jest).

💡 Why work with me?

Seniority: I bring calm and structure to projects. I have modernized legacy systems and brought new products from scratch to MVP status (e.g., Travix).

Bridge Builder: As a frontend expert with a strong backend background (C#, PHP), I understand the entire application and communicate efficiently with backend teams.

Pragmatism: I rely on proven solutions rather than hype. Clean code and type safety (TypeScript) are standard for me, not optional.

Languages: German (Fluent), Spanish (Native), English (Fluent).
