Samuel Maia

I am a seasoned Software Engineer with over 6 years of experience in both North America and Brazil, specializing in creating high-performing SaaS apps. My expertise spans the JavaScript ecosystem including TypeScript, Node, and also Java. During this time, I worked principally on Frontend Applications using Vue.js and React.js to achieve my team goals. I have a strong foundation in REST APIs earned from the full-stack experience. I thrive in English-first environments and have a proven track record of solving complex problems while fostering team collaboration.

I worked for multiple business sectors during my experience including health care, assurance, bank, market research, and map solutions for telecommunication companies.

Throughout my career, I have successfully delivered code and direction to projects that significantly improved user experience and operational efficiency.

Achievements that I was part of:

• Was a key engineer during the migration of core Geosite platform components from a monolithic to a modular microservices architecture, doubling SaaS subscriptions/increasing revenue by 100%.

• Acted as technical lead and primary code reference in a team of five developers and led the rebuild of the front-end and back-end of a dynamic dashboard system, optimizing front-end and APIs, cutting dashboard’s load time by 50%.

• Refactored the ghost movement feature in the Draw2D library to support real-time shape manipulation in the Geosite drawing tool, eliminating 100% of app freezes during shape interactions.

• Improved developer experience and component scalability by reducing a key feature implementation from 3000 to ~700 lines of code.

• Refactored the tree structure to reduce load time on tree-based pages by 90% and cut 99% of redundant API requests on main app pages.

• Refactored the HOOP (Hours of Operation) app to replace a problematic patch-based update system with real-time, per-entity updates—eliminating sync issues and reducing related support tickets by over 90%.
