    I got my hands on iPhone SDK when it was first released in 2008. I was intrigued by the responsive touch interface, and since then I've written over 50+ apps and have worked with dozens of clients worldwide. In 2014 I started working with Android SDK as well. It was quite a change (and challenge..) coming from the iOS ecosystem but I embraced it and have become quite fond of it since then. Nowadays, it's very common for me to develop Android and iOS versions of apps alongside (although Natively). I've worked with clients from Silicon Valley to Singapore with experience in front and backend. I love developing MVPs (Minimum Viable Products) for my clients to test the market. If you have an idea, let's chat!!

I have over 13 years of hand-on experience in web development, over 8 years with the full MEAN/MERN stack and counting. Willing and will participate in all parts of a project, not just taking a technical design and making it live. I'll argue my point if I see it beneficial for the common goal, and can manage a small technical group and even with a vague requirement coming either from a roadmap or a client -- estimate the effort and produce the results, either solo or in a group. TL;DR Full-stack here - and not just with tech, but with business and people, too :) Warm tracks: Past 5 years been working in a US startup (Pangeam) as a FE team lead, focusing on data viz, statistics and data structures.
