À propos de Guilherme

Hello!

I’m a Backend and Full Stack Developer with a strong foundation in C# and TypeScript, and a genuine passion for building impactful digital solutions. Over the past several years, I’ve worked across industries like finance, energy, and pharma, where I’ve designed and modernized systems—from robust enterprise applications to cloud-native microservices.

I thrive when tackling complex challenges: whether it’s modernizing legacy systems, implementing event-driven architectures, or designing scalable, resilient services using AWS and Azure. I’ve worked extensively with telemetry technologies like RabbitMQ, SQS/SNS, and built systems grounded in Domain-Driven Design, SOLID principles, and clean architecture. Writing high-quality, maintainable code isn’t just a goal, it’s a mindset I bring to every project.

What drives me is the balance between technical depth and real-world business value. I enjoy being part of agile teams where ideas are shared freely, quality matters, and innovation is sustainable. I’ve also had the opportunity to lead and mentor development teams, focusing on deadlines, code quality, continuous improvement and creating an environment where people grow together.

Whether it’s a high-pressure delivery or long-term architectural evolution, I aim to provide both tactical and strategic solutions that align with business needs. At the end of the day, I love using technology to build things that matter. Things that are not only technically sound, but genuinely useful.
