Experience
VoIP Maker
Created the back-end of a high-performance VoIP portal, using Python/Django as the project back-end. Used Redis to cache a huge amount of data and Celery for asynchronous calls and workarounds in Django. Also added integration with the external billing solution using public API.
Billing Platform
Developed a high-load billing platform, integrated with many VoIP softswitches using different methods. Used a variety of technologies: Python for the server side, PHP for processing interface information, and Redis for the cache. Developed a small test framework using PHPUnit and platform API. Used PostgreSQL opportunities such as procedures and replication for failover.
