Murilo Dias da Costa
Software Engineer / Backend
I build high-performance, scalable, and reliable backend systems. Focused on engineering clean codebase architectures, optimizing database performance, and delivering robust integration solutions that drive operational efficiency.
Specialized in the Java ecosystem and relational databases, I have proven experience bridging the gap between complex ERP architectures and external ecosystems (Marketplaces, APIs). I specialize in identifying system bottlenecks, rewriting complex SQL queries, and designing automated workflows that eliminate hours of manual labor.
Based in Brazil, pursuing a B.S. in Computer Science, and ready to turn complex technical and architectural challenges into elegant, high-throughput digital solutions.
