Michel Coelho da Silveira

I’m a Senior Software Engineer with 7 years of experience developing web applications, SaaS platforms, financial systems, and interactive digital products. I’m especially strong in Front-End Engineering, using Angular and TypeScript to build reliable, maintainable solutions.

Most recently, I developed a scalable Role-Based Access Control (RBAC) system in partnership with backend engineers, implementing end-to-end authorization across front-end and backend services. I achieved a 0% rate of unauthorized requests by ensuring users could only access permitted features and operations.

I also implemented a centralized error management solution with structured error codes and user-friendly messaging. This improved debugging efficiency while providing clear feedback, reduced support overhead by cutting support tickets related to unclear error messages and usability confusion by 90%, and strengthened error diagnosis across the platform.

Earlier, I helped deliver responsive interfaces and complex forms during the replacement of a legacy financial platform, collaborating closely with business and technical stakeholders. I’ve also built interactive experiences—developing casino and slot games with Phaser and TypeScript, establishing scalable animation pipelines, and optimizing rendering and loading performance to enhance scalability, maintainability, and player experience.
