With a background in Computer Engineering, I am an experienced professional in the architecture and development of distributed systems, with solid knowledge in cryptography and the payment sector with smart cards.As an enthusiast of microservice architectures, I have implemented distributed authorization and payment processing systems for major brands, using Kubernetes in conjunction with other AWS resources to ensure high availability, performance, and resilience. Through the high scalability of this kind of architecture, I have avoided the monetary and evolutionary costs of monolithic systems commonly used in the financial sector.Passionate about the world of cryptography, I've been responsible for the implementation of cryptographic operations involved in the processing of EMV (Europay, Mastercard, Visa) transactions and management of this branch of smart cards, using cryptographic techniques to protect sensitive data at rest and in transit, as well as for the management of cryptographic keys. My knowledge spans from symmetric and asymmetric algorithms to the use of digital certificates and PKI structures, ensuring both the confidentiality and integrity of transmitted information. I also had the opportunity to support security teams as the technical arm, assisting in certification and compliance with market standards such as PCI DSS, PCI PIN Security, and ISO 27001.I am attracted to complex challenges and am always seeking new opportunities to apply my skills and work alongside innovative teams that share the vision of a more secure, connected, and agile future, both on the final product and during development cycles.
