Software Engineer at PayJoy who developed credit-service integrations and internal tools for teams in Colombia and the Philippines.

Colombia

Message

At PayJoy, I worked on opening and scaling the credit line service in Colombia and developed integrations with strategic partners, including Grupo Éxito, Chedraui, and Telefónica. I also developed the Claro Hub integration and participated in the Walmart/Cashi integration.

For PayJoy through Lean Tech, I participated in migrating the M3 sales platform from AngularJS to Vue.js. I implemented a self-service module for customers and built bulk-update tools for administrators, merchants, and salespeople.

At Heinsohn, I was Tech Lead on the CareTree project, migrating infrastructure to AWS and modernizing its architecture. I also Dockerized the project, separated the QuickBooks integration into a microservice, and upgraded Laravel; my cybersecurity specialization informs how I approach building secure software.
