I am a senior iOS and Android native developer. I was a very successful developing for over 6 years, working for several tens of companies and individuals all over the world, even a full-wish young man. As well as development of new apps, I work on maintenance of existing popular apps, and I always aim to maintain a long term relationship with my clients. Whether you've lost original developer, or need to add additional features, or want a new app from scratch, I can step in and take over wherever you need. Thank you
