PHP Developer Recife, Brazil

I work developing web applications and RESTful webservices in PHP 4 and PHP 5 in both pure PHP and using the Yii2 framework, in a Linux VM running on Virtual Box for Windows. I also analyze, model and document applications workflow using Bizagi Modeler and do system analysis. We use Scrum to manage software development. I also participate and give opinion on hiring interviews and lead junior programmers.

Notable Contributions

Through my own observation, I identified process bottlenecks that caused unnecessary stress between the company and its clients and suggested changes in the way we deal with clients. The suggestions were accepted by company owners and reduced the amount of clients complains and helped the company improve client fidelity.

Technician on Traffic Designs Recife, Brazil

I worked on a R&D project to make an AI software to optimize car flow on big cities by adjusting the time of traffic lights in a network. I coded most of the software, which was written in C++.net, made the Windows Form UI and helped to fine-tune system genetic algorithm AI. I also tested, debugged, found most of the memory leaks and fixed them, made a user manual and the software installer. I too modelled traffic networks in a traffic simulator in order to estimate how much the car throughput should improve when the traffics lights were adjusted according to our software. I was also used to have meetings with the clients (local traffic departments) to understand the problem and define strategies to solve them (decide where the field team should be send to collect data and on which semaphores we would work). Later on, I made the system read from a MS SQL Server database and change traffic lights on real time.

SAPA

On my own, I developed an artificial intelligent software for automated generation of college classes’ timetables. Given restrictions of room capacity, which subjects is taught by which professor, which subjects the students of each semester should apply, among others, the software used its AI to heuristically search a vast number of possibilities and give a feasible timetable that can actually be applied in real world, making a computer do in a few minutes or hours what humans usually take weeks. A new and improved version of SAPA was being developed for the Federal University of Pernambuco as requested by the institution. Unfortunately the project was never completed due to financial problems.
