I am a software developer with over 9 years of experience, specializing in backend development with PHP, Symfony, and databases like MySQL and MongoDB. I am passionate about building robust systems, writing clean code, and adhering to best practices in software architecture, including Domain-Driven Design (DDD) and automated testing. Furthermore, I thrive in agile environments and enjoy collaborating with cross-functional teams to deliver scalable and maintainable solutions.
I approach my work with a positive attitude and strive to bring good energy to every project. Throughout my career, I've had the opportunity to contribute to exciting projects, helping them grow in a well-tested and maintainable manner. I enjoy sharing ideas and brainstorming with others to find the best solutions to challenges. Outside of work, I love meeting new people, learning from different perspectives, and embracing a life full of challenges and positive vibes.

Designed, developed, and maintained backend services following clean architecture principles and Domain-Driven Design. My work included integrating third-party systems and APIs, such as hotel chains for the 360 project, fast-booking features, loyalty programs, and Wallet integration. I worked extensively with data pipelines and synchronization processes, particularly using Tinybird for real-time analytics, managing dimension tables and optimized schemas. I configured monitoring and observability with Grafana and log-based systems (Loki/OpenSearch) to analyze performance and set up alerts. I collaborated on infrastructure in a Kubernetes and AWS environment, simulating services with LocalStack when needed. I wrote and maintained automated tests with PHPUnit and Behat, applying patterns like Object Mother to ensure reliable API behavior. I also participated in refactoring legacy code, including Doctrine mappings and data model changes, standardized API responses to improve maintainability, and investigated and proposed solutions to technical challenges such as failure handling in data synchronization, schema evolution, and performance optimization.

As part of a 3-member team, I focused on search and product-related functionalities for a second-hand clothing platform with over 7 million products and approximately 2 million users across Mexico and Colombia. I developed and maintained the search system and product features, ensuring scalability and performance at high data volumes, and built and managed a validation and moderation tool to guarantee the quality and compliance of user-uploaded products. I collaborated closely with the team to deliver features end-to-end, from requirement analysis through development and deployment, contributing to the stability, growth, and overall user experience of one of the leading second-hand fashion marketplaces in Latin America.

I worked in a team of 3–5 people (2–4 developers and 1 Product Owner), where I was responsible for ingesting and processing magazines for the B2C business and major publishers such as Meredith (People, InStyle, Fitness, Food & Wine). I designed, developed, and maintained backend services following clean architecture principles and Domain-Driven Design. My work included integrating third-party systems and APIs, writing and maintaining automated tests with PHPUnit and Behat (using patterns like Object Mother to ensure reliable API behavior), and maintaining a large legacy system used by internal staff and publishers while contributing to the design and development of a new microservices-based platform. I implemented asynchronous communication between services using RabbitMQ to improve scalability and reliability, and integrated observability and monitoring tools such as Kibana, CloudWatch, and Sentry, configuring metrics and alerts for system stability and proactive incident response. I collaborated closely with the Product Owner to analyze requirements, propose technical solutions, and estimate delivery effort based on value and complexity, and I delivered features end-to-end, from design and development through testing (unit, integration, and acceptance) to deployment in production.

Working remotely with a 3-month stay abroad, our team developed a bridge application to automate the transfer of reservations and room rates between different hotels managed by the client’s system. The tool processed information in SOAP format and mapped it to a JSON API, utilizing systems like RabbitMQ for queuing and Memcache for cache management.
