Carlos Willian De Carvalho

Hi! I’m Carlos Carvalho, a passionate software developer from Brazil with over 14 years of hands-on experience in full-stack development. Throughout my career, I’ve worked across a variety of industries including education, retail, energy, agriculture, and finance — always focused on building scalable, impactful, and user-friendly solutions.

I specialize in modern web and backend development using:

• Frontend: React, TypeScript, JavaScript, HTML5/CSS3
• Backend: Java, Spring Boot, Node.js
• Databases: PostgreSQL, MySQL, Oracle
• Other Tools: Git, Docker, CI/CD pipelines, ArcGIS

Here are some key roles I’ve held:

• At XMOBOTS (2023 – present), I’ve contributed to a modular SaaS platform for managing agricultural drone operations. I worked on drone sales, flight authorization (XUTM), and government integrations — helping build a platform expected to serve thousands of users.
• At Codex/Kaffa Espresso (2022 – 2023), I helped utility companies manage energy networks more efficiently. I designed safety algorithms to prevent workplace accidents and reduced maintenance costs by building systems to manage parts and services.
• At Cobmais (2021 – 2022), I developed APIs and import tools for a debt collection SaaS. I also integrated browser-based dialers and helped increase company revenue by creating a self-service site for debt renegotiation.
• At Expert Sistemas (2020 – 2021), I worked on a POS system used in restaurants and retail stores. I helped integrate the system with iFood (Brazil’s leading delivery platform) and federal/state tax APIs for electronic invoicing.

I also have a Master’s degree in Computer Science, with research in computer vision and digital image processing, and have published a peer-reviewed paper.

My strengths include fast learning, problem-solving, clean code, and great communication with technical and non-technical stakeholders. I’m passionate about writing code that solves real-world problems — and I’m always looking forward to building something meaningful with great teams.
