Pará, Brazil
Summary
👤
Senior🎓
Top SchoolMark Sales is a solutions architect and product owner with four years of hands-on experience building and scaling high-availability e-commerce and marketplace platforms. He combines a full-stack engineering mindset with deep backend expertise and rigorous DDD, TDD and SDD practices to deliver resilient integrations, payment split flows and batch processing at enterprise scale. Proficient across the Oracle commerce ecosystem (OCC, OSF, OIC, CMS, DB) and cloud orchestration on AWS/Azure, he has led the design and launch of a unified Seller Center (Sellmate) that became a new business unit. Equally comfortable coding core APIs in Node.js as he is shaping product strategy with stakeholders, he focuses on performance, observability and long-term maintainability. Outside work he studies philosophy and is writing a post-apocalyptic sci‑fi novel, a detail that hints at his taste for complex systems and narrative-driven thinking.
