Since 2001, I dedicated much of my development experience with PHP and MySQL to the management of several web systems for companies, public entities, associations through my company GNNEXT.
In this situation, I implemented CRMs, payment management and financial control systems, administrative control modules, event management, budget control, data issuance for IR, online betting systems, issuance of documents, automated mechanisms and integration with different systems from other companies (with banks, construction companies, suppliers, etc.)
During this time, I also worked with migration between platforms and complex database systems that needed to be converted to open source platforms (PHP, MySQL, Linux).
There were many years of requisites, specification, concepts, models, development, debug, documentation, testing, automation, auditing and finally, delivery. I actively participated in all areas of the development process of a web system, not only as a team manager, but also as a developer and a code auditor.
