Tech Founder | Full-stack Developer | IoT Expert

I'm a freelance mobile & full-stack developer, passionate about computer graphics and user experience, designing APIs and creating developer tools. I love to help startups to build their MVPs, design their APIs and solve their technical challenges by taking in account both product and business impacts. I can lead projects from design to distribution in different domains: web, mobile, backend, IoT and APIs/SDKs.
