• Deployed the API Gateway in a Kubernetes cluster, ensuring high availability and scalability.
• Provisioned and maintained the surrounding infrastructure, streamlining deployment workflows and operational monitoring.
• Optimized gateway performance and security to support unique API consumption patterns.

A technology company that provides ride-hailing, food delivery, and freight transport services through a mobile app. Matias led the migration of critical endpoints to a cutting-edge APIGateway, resulting in improved efficiency and functionality. He collaborated with the team to propose logic improvements and conducted comprehensive tests to ensure quality.

• Successfully migrated multiple high-traffic endpoints to the new API Gateway, reducing latency by up to 35% and improving request handling reliability.
• Designed and implemented optimized request/response workflows, enhancing scalability for millions of daily transactions.
• Created and executed comprehensive automated test suites, increasing code coverage and reducing production incidents by 20%.
• Proposed and implemented logic improvements that simplified code maintenance and improved developer onboarding efficiency.
• Partnered cross-functionally with product and infrastructure teams to ensure a seamless transition with zero downtime during migration.

Matias played a key role in developing backend services for an autonomous drone, integrating it with sensors for enhanced home security. Utilizing AWS CDK architecture, he ensured the reliability and functionality of the drone's services.

• Designed and developed backend services enabling the drone to perform autonomous functions and respond to user commands in real time.
• Implemented AWS Cloud Development Kit (CDK) architecture to define cloud infrastructure as code, improving deployment consistency and reducing provisioning time.
• Integrated the drone with alarm and motion sensors, enabling automatic activation in response to security events.
• Built and executed comprehensive automated and manual test cases, increasing service reliability and reducing field-reported issues.
• Collaborated closely with hardware, security, and mobile teams to deliver a seamless user experience from event detection to drone deployment.

As a member of the backend team, Matias played a key role in developing secure micro-services for storing card information and processing transactions. He collaborated with team members to integrate the services with external APIs, ensuring smooth and fast transactions for their customers.

• Designed and implemented a microservice in Go to securely store customer card information.
• Built a dedicated microservice to handle debit card transactions, prioritizing security, reliability, and low latency.
• Integrated microservices with external systems, including payment and balance APIs, to enable smooth transaction flows.
• Wrote comprehensive unit and integration tests in Go, improving service quality and reducing production issues.
• Applied best practices in Go development to maintain high standards of code quality and performance.
