Versatile Software Dev, Specializing in Kotlin & C++

I'm a polyglot software engineer with over five years of experience delivering products in healthcare, ecommerce and fintech. During that time I have built mobile apps, desktop applications and web services. I have a strong background in Kotlin and C++. I also spent significant time working with C# and .NET. I'm used to working in international environments and currently live in Japan. From startups to established, international enterprises, I have both been part of cross-functional SCRUM teams and solely responsible for products. In previous roles, I was often praised for strong communication skills and diving deep into the business domain. I strongly care about the products that I am working on, and feel most encouragement when addressing actual user needs. Please take a look at my previous work experience as well as my portfolio for further information about my skills. Let's get in touch!
