About Me
A bit about my journey and interests
I'm a full-stack developer passionate about technology and transforming ideas into web applications that truly make a difference. I work with JavaScript, TypeScript, PHP, and C#, handling both the front-end and back-end, depending on the challenge.
Currently, I develop custom solutions for different types of businesses — I’ve worked on industrial production systems, CMS platforms, CRMs, and institutional projects. I enjoy creating practical interfaces, writing clean code, and thinking about system scalability from the start.
I’m always looking to learn something new, whether it’s a technology, a tool, or a smarter way to solve problems. I believe technology is a powerful tool for transforming businesses (and people’s lives) — and that’s what keeps me motivated to keep evolving.

Experience
Here are some of the projects I have worked on
PCP System for Production Line
I developed a complete Production Planning and Control (PPC) system from scratch for a packaging industry, covering everything from order registration to automatic machine routing. The solution included a real-time web interface for operators, efficiency dashboards for supervisors, and a robust API for integration with other systems. The entire environment was prepared for high availability, with continuous deployment on a Linux server via PM2 and a reverse proxy configured in Nginx.
Modular SaaS CMS Platform
I conceptualized and developed a multi-tenant CMS platform for managing websites and web applications for different clients, using a single scalable modular codebase. The solution allows data schema customization, adding field extensions, and integrating external services via configurable adapters. I focused on security, data isolation, and ease of deployment, enabling the system to serve multiple clients simultaneously without cross-impact.
Condominium Management CMS
I worked on maintaining and evolving a web system aimed at condominium management, focusing on managing common area reservations, internal communication, and document and notice management. I implemented improvements in the reservation flows, fixed critical bugs, and optimized performance to ensure greater system stability and reliability. The application now manages over 500 condominiums and has 2,000 active users.
Occupational Medicine Management System
I was responsible for maintaining and evolving a complex ecosystem of microservices for managing occupational medicine appointments and services. The system integrated multiple SQL Server and Oracle databases, as well as external health and analytics systems in Power BI. I worked on standardizing integrations, refactoring the front-end in Vue.js, and restructuring microservices to improve scalability.
Institutional Websites Development
I participated in the development of institutional websites for sectors such as real estate, supermarkets, and high-end furniture brands. The applications were developed in Next.js to ensure maximum performance and optimized SEO, with multi-language support and dynamic integration with content management systems.
