Colombia

Message

At Publicis Groupe, I led backend architecture and development across enterprise platforms, defining API standards and system integration patterns with Node.js, Express, AWS, and Serverless technologies. I also integrated AI models, APIs, and agents into backend systems, using tool-calling workflows and the Model Context Protocol.

At Epam Anywhere, I led the migration of a Liberty Mutual platform from a monolith to AWS microservices, replacing backend services with independently deployable AWS Lambda services. I applied Test-Driven Development and maintainability practices to improve code quality and deployment reliability.

Earlier, I contributed to backend systems and cloud modernization at Globant, and at Toyota North América I helped develop two products for a Toyota dealership and led the creation of a tool for plate image and car bin recognition using computer vision and Deep Learning.
