Mario Barbosa

I’m a technical professional combining data analysis with full-stack execution to deliver reliable, business-critical solutions. My work centers on turning complex requirements into clean data flows, accurate reporting, and well-documented systems that end-users can trust.

Most recently, I supported and built within the software development lifecycle through an in-depth system focus on data analysis and quality. I developed a critical revenue calculation module for the Budget System, designing relational architecture in SQL Server and integrating it with an ASP.NET HTML/CSS web interface.

I also strengthen performance and integrity by reengineering and optimizing Stored Procedures and complex queries in SQL Server. I achieved a 90% reduction in integrity/ execution times (latency) and increased system availability for end-users.

Before moving fully into development roles, I transitioned from technical and customer support—selected from a pool of candidates after excellent psychometric and technical assessment scores. I bring strong diagnostics, SQL Server user/account administration experience, and a collaborative mindset to troubleshoot complex issues with internal teams and business areas.
