At KAZ Formaturas, I develop and evolve internal business systems and build APIs and external-service integrations, including Zoop and Pagar.me payment workflows for credit card, bank slip, and Pix.
Previously at Z-Systems Software, I developed applications and financial dashboards and implemented RabbitMQ messaging to process more than 50,000 financial transactions per day. I also configured and maintained AWS infrastructure.
Across roles at Tecsomobi and Medprev, I developed backend services and payment integrations, including Pix recharges for public transportation cards and asynchronous processing with AWS Lambda, SQS, and SNS. Earlier, at Ás Formaturas, I developed an online seating map that helped reduce queues and congestion at the company's office.
