Lucas Meira | Portfolio

About Me

I'm Lucas Henrique Milhomem Meira, a passionate Full Stack Engineer with over 10 years of experience building scalable SaaS products and digital solutions. I specialize in modern frontend and backend technologies, working with Angular, Spring Boot, and a wide range of databases like Oracle, SQL Server, MongoDB, and Firebase.

I’ve led teams and delivered high-impact solutions in industries such as Banking, Payments, Real Estate, and Healthcare. My work spans from designing microservices and event-driven architectures (Kafka, MQTT, IBM MQ) to ensuring quality and security with tools like SonarQube, Fortify, and Git.

I thrive in Agile environments, apply clean architecture principles (Layered, Hexagonal, MVC), and prioritize maintainability through robust testing and CI/CD pipelines. Whether leading teams or collaborating cross-functionally, I’m driven to create reliable, efficient, and impactful software.
