Software Development & Performance Engineering
With over 20 years of experience, I help Swiss companies and engineering teams build performant, maintainable software solutions.
For Businesses
Need a custom web application, or is your existing software grinding to a halt? I deliver straightforward, professional solutions—from requirements gathering to production deployment. You focus on your business; I handle the servers, databases, and pipelines.
For Engineering Teams & CTOs
Looking for senior-level reinforcement on complex backend projects, database optimization, or infrastructure automation? I work independently, bring deep technical expertise, and ship clean, maintainable code with minimal ramp-up time.
