Android Software Engineer

Entrepreneur | Android Developer | UX/UI Designer | Java Instructor I am currently working for DealerSocket as a Android Software Engineer. In the past I've worked full time as a freelancer on Android development and UX/UI design. I work primarily on building and enhancing both businesses & individuals applications on the Google Play Store. I have over three years of extensive experience in both backend and front-end mobile development.

Experienced tech lead, full stack mobile & web engineer, great communicator

Full stack mobile & web engineer having 15 years of experience. I'm a very effective communicator thanks to my experience of working with clients as a freelancer. Having been the CTO of 3 companies (two of them my own startups), I practiced code reviewing and mentoring a lot. As a result of working for 6 years at Nokia Research as a research engineer, then 3 years as a freelancer and also later on becoming the CTO of 3 companies, I'm very good at prototyping, figuring out the initial architecture for new services and general problem solving. The technologies I'm using in the past few years and the ones I'm strongest at are: python, django, java, android and javascript. I also have a strong interest in and can help with writing maintainable and well designed, high quality code, creating well designed APIs, defining best practices for a development team.
