I am currently accepting new mandates. Please contact me directly to discuss your specific technical challenge and how I can provide immediate, senior capacity.

Seniority, Scalability, and Speed.

I am a senior full-stack software engineer and product builder available for high-leverage project mandates. My core focus is on designing, migrating, and optimizing complex, data-intensive web applications for scale-ups and established tech companies across Switzerland and Europe.

I offer immediate capacity to help your team overcome critical technical bottlenecks, accelerate crucial feature development, or execute necessary system migrations.

My Core Value Proposition

Immediate Capacity – I bypass the long full-term hiring process. I onboard fast and start delivering production-ready code within days.
Application Scaling – I specialize in successfully transitioning established applications from legacy systems to modern, maintainable, and high-performance architectures.
Data-Driven Focus – I have proven expertise in building and managing scalable data acquisition, tracking, and presentation layers, demonstrated by my own bootstrapped startup Chronoscout (https://chronoscout.co).

Key Technical Expertise

I work primarily with modern, in-demand technologies to ensure long-term stability and performance for your products:

Frontend – Deep expertise in Angular, React and TypeScript, focusing on high-performance UIs and data visualization.
Backend – Specialization in Node.js (Express.js, Remix, Next.js, NestJS) for building high-availability, high-maintainability, low-overhead business logic.
Database/Data – Proficient in SQL and noSQL alike, using kysely, Prisma and other kinds of query builders for migrations and type-safe data access.
DevOps/Cloud – Experience with Docker, CI/CD pipelines and Nginx for streamlined deployment and cloud architecture.

Experience and Mandates

Senior Experience – 8+ years of senior development experience, 12+ years in the software industry, including successfully rebuilding mobile applications and critical features at Eventfrog.
Product Founder – Founder and sole developer of the live, data-driven application Chronoscout (https://chronoscout.co).
Target Mandates – I am actively seeking 3- to 6-month contract mandates with FinTech firms, dynamic scale-ups and tech-focused SMEs.

The Bottom Line

You are not just hiring a developer; you are securing a senior partner who thinks like a product founder. I bridge the gap between complex engineering challenges and clear business outcomes.

If your scale-up is facing critical technical bottlenecks or needs to accelerate a key roadmap feature (and you can't wait months for the traditional hiring process) you need my capacity.

I deliver secure, scalable code with a laser focus on your growth and business value.

Don't lose momentum. Contact me today to discuss a high-leverage project mandate.
