Guatemala
Hi, my name is Maria Eugenia, and I’m a software developer with over 15 years of experience, mainly focused on backend development.
My strongest area is Ruby on Rails, and I’ve worked extensively with APIs, database systems, system integrations, and production support. I’ve worked in financial and fintech environments, including Arcus by Mastercard and Tapi, where I was involved in developing and maintaining critical payment systems.
One thing I particularly enjoy is solving complex technical problems. For example, in my previous roles, I’ve worked on identifying and resolving production issues, improving system reliability, automating processes, and optimizing database and application performance.
I also have experience with technologies such as JavaScript, Python, SQL, Oracle, MySQL, PostgreSQL, MongoDB, Git, AWS, and ETL tools such as Talend Studio.

Ecuador
Soy desarrollador de software con más de 6 años de experiencia construyendo sistemas web y aplicaciones en producción.
Me especializo en backend con Laravel, NodeJS y PHP, y he trabajado en proyectos de diferentes industrias.
Mi ultimo trabajo fue en PROPEMAR S.A., una empresa exportadora de camarón, donde desarrollé y matuve un sistema ERP interno con más de 10 módulos críticos: rrhh, logística, control de calidad, exportación, entre otros.
Este proyecto me ha permitido crecer en la toma de decisiones técnicas, la integración de sistemas y la optimización del rendimiento bajo presión operacional real.
En paralelo, he trabajado como freelancer en proyectos de mediana y gran escala: módulos de gestión de eventos con emisión automática de certificados, sistemas de control administrativo y financiero para federaciones educativas y plataformas de reportes multi institución.
