Hi, I’m Luiz Fernando Justino. I’m a Senior Software Engineer with over 10 years in IT, specializing in software engineering for most of that time. I’m currently pivoting extensive backend expertise into the .NET ecosystem (C#, ASP.NET Core, Entity Framework) while leveraging PHP (Laravel) for high-impact projects. I’m a hands-on professional who thrives on solving complex integrations and driving architectural decisions that deliver value. I’m known for fostering a culture of quality and collaboration within engineering teams. I’ve led and contributed to microservices and digital transformations, reducing processing times from days to minutes and improving system reliability. I enjoy mentoring junior developers, documenting standards, and helping cross-functional squads ship robust software. My goal is to keep delivering high-quality, scalable solutions while continuously learning and improving processes.
