Mfdev

FullStack Software Engineer

Apr 2024 – Present · 1 yr 11 mos · Tapira, Minas Gerais, Brasil · Remote

MfDev is my company, through which I work as a FullStack Software Developer under PJ contracts, providing services to different clients and projects.
I was the lead developer for a real estate startup, where we built a platform for listing properties, facilitating rentals, sales, and partnerships— all designed to empower real estate agents while ensuring security for users. The application was developed using Next.js 15 and Material UI, integrating with CRECI-SP APIs via NestJS on the backend. Additionally, we implemented advanced map features using Google Maps, with a strong mobile-first and UX/UI-focused approach.
In the same startup, I contributed to the development of a social network for architects, enabling professionals to showcase their projects in 3D, PDFs, photos, videos, and text. The platform featured followers, profile pages, bios, and post comments, making it a fully functional social media experience tailored to the architecture industry.
Beyond that, I collaborated on various other projects, including a maintenance reporting system for aircraft built with React, ShadcnUI, Tailwind CSS and Python and a reporting system for medium and large vessels developed for a multinational company in Italy. These experiences have allowed me to apply my technical expertise in diverse fields, always ensuring scalability, performance, and intuitive user experiences.
I developed a donation app – Built a platform for churches, NGOs, and third-sector
institutions, enabling recurring and one-time donations, with a smooth, mobile-first experience.

Software Developer

Jun 2020 – Apr 2024 · 3 yrs 10 mos · Araxá, Minas Gerais, Brasil · Hybrid

I collaborated in the development of systems for insurance companies, working as a Level 2 Support Engineer. I had direct contact with major clients, participated in strategic meetings, and ensured the stability of applications. I worked primarily with React and Node.js, actively contributing to frontend-related decisions and initiatives across the company.
One of the most impactful challenges was helping to develop a React-based insurance marketplace. After its launch, I led the migration from a monolithic architecture to microfrontends using single-SPA, enabling greater scalability and autonomy between modules. Additionally, I worked with NPM packages, creating reusable solutions to streamline internal development.
I also had the opportunity to conduct technical interviews for new candidates, mentor interns, and participate in several War Rooms to resolve critical production issues. These experiences strengthened my ability to perform under pressure and deepened my strategic understanding of frontend architecture and best development practices.
