About
I'm Sascha Hillig, a Berlin-based technologist with a unique blend of engineering depth, design sensibility, and business acumen. Over two decades, I've evolved from writing my first lines of code to leading engineering teams and founding companies.
What sets me apart is my holistic approach: I don't just build features, I build products. I don't just write code, I solve business problems. Whether it's architecting a scalable backend, designing an intuitive interface, or defining a go-to-market strategy, I bring a complete perspective to every challenge.

Approach
I believe in pragmatic solutions over perfect theories. Every technical decision should serve a business purpose. Every design choice should enhance user experience. Every line of code should be maintainable and scalable.
My work is characterized by:
- • Analytical thinking - Breaking complex problems into manageable solutions
- • User focus - Building products people actually want to use
- • Technical excellence - Writing clean, tested, maintainable code
- • Business alignment - Understanding the why behind every feature
- • Continuous learning - Staying current with technology and methodologies
Life Beyond Code

As a father of three, I've mastered the art of balancing complex projects with family life. Managing a household with three kids has taught me invaluable lessons in time management, patience, and creative problem-solving — skills that directly enhance my professional work. The responsibility of providing for my family drives my commitment to delivering exceptional, reliable solutions for every client.
When I'm not coding or spending time with my family, you'll find me practicing Shotokan Karate, where I hold a black belt. The discipline and focus from martial arts, combined with the organizational skills from family life, create a unique perspective that I bring to every project.

Based in Berlin, I work with clients globally, bringing a European perspective on privacy and quality to international projects. My home office setup allows me to be both present for my family and fully dedicated to my clients' success. The real benefit for you: I'm hyperavailable when needed. No commute means I can respond to critical issues at 11pm, join early morning calls with different time zones, or quickly address urgent requests. When your production system needs attention, I'm just a room away.
