With over 13 years of progressive experience in software development, I've established myself as a versatile Full Stack Developer capable of architecting and delivering complex enterprise solutions across multiple domains.
Technical Evolution Journey
My career began at CODIUB (2010-2013) where I cut my teeth maintaining and enhancing PowerBuilder applications for municipal education systems. This foundational experience taught me the importance of reliability in systems that organizations depend on daily, as I developed critical reports and implemented bug fixes for essential educational administrative tools.
At SigPharma (2014-2016), I was instrumental in the explosive growth of a pharmacy network management system that scaled from serving a single client to supporting 21 pharmacy networks. I worked across the full technology stack—from Adobe Flex and Java to MySQL database management—while implementing comprehensive features including service order management, reporting systems, purchase order tracking, and vendor quotation workflows. Notably, I designed and implemented a sophisticated audit system that tracked all user actions, establishing accountability throughout the platform, and began migrating components to AngularJS to modernize the system architecture.
My experience at QAT (2016-2018) exposed me to enterprise-scale development practices within a North American software factory. Working in Scrum teams on an HVAC customer management system, I deepened my knowledge of unit testing, agile methodologies, and frontend development with jQuery and AngularJS, solidifying my ability to collaborate effectively in structured development environments.

Advanced Architecture & Solutions
At LuizaLabs (2018-present), I've demonstrated my capability to transform business concepts into sophisticated technical solutions. After initially working on a B2B e-commerce platform for Latin American markets, I took on increasing responsibility, culminating in my most significant achievement: evolving a proof-of-concept into a production-ready B2B e-commerce platform that meets rigorous enterprise standards.
This comprehensive system showcases my expertise in:
  • Modern Frontend Architecture: Implementing React and Next.js with server-side rendering for optimal performance and SEO
  • Backend Infrastructure: Designing and building a Backend-for-Frontend (BFF) with Express.js that incorporates token-based security, correlation ID-based logging for distributed tracing, and centralized error handling
  • Scalability Solutions: Implementing Redis-based session management to enable stateless application pods that can scale dynamically based on demand patterns
  • Component Architecture: Creating a shared component library that standardizes design patterns and accelerates development across multiple projects
  • Quality Engineering: Restructuring architecture and implementing comprehensive testing strategies to meet enterprise metrics for security, performance, and test coverage
My technical toolkit has expanded to include:
  • Frontend: React, Next.js, AngularJS, jQuery, Material-UI
  • Backend: Node.js, Express.js, Java
  • Databases: MySQL, Redis
  • Architecture: BFF pattern, Microservices, Server-side rendering
  • DevOps: Pod-based scaling, Containerization
  • Methodologies: Scrum, Agile development, Test-driven development
What distinguishes my approach is the ability to balance technical excellence with business requirements, creating solutions that are not only technologically sound but also deliver tangible value to both businesses and end-users.
