    I am an innovative, extremely detail oriented and perfectionist Software Development Architect, with expert knowledge in VoIP, audio/video streaming and processing, messaging and social media. My a little over 8 years of experience in VoIP industry gave me a strong knowledge of the protocols, technologies and available solutions. 3 years of successful mobile applications development, architect and project management gave me confidence in creating robust and technologically challenging applications. I am passionate about developing robust, innovative and leading edge applications, getting increasingly challenging assignments and applying disruptive technologies. Looking for a work on technologically challenging projects (in an agile environment preferably), while offering my expert knowledge base, ability to learn quickly and apply new techniques. I usually bid slower than others, because of reading the full job description, trying to estimate all requirements, needed technologies and solutions.  less
