About Me

A while ago I decided to leave the corporate world behind me and start to work from home. I have broad experience in designing, programming, and implementing large information systems. The ability to provide in-depth evaluation and analysis of unique complex technological issues. I found my passions in communication technologies like Asterisk and Twilio, developed multiple mobile apps and really enjoy to integrate systems via REST API's.
