Skills

Experience: Solution Architecture with a clear focus on E-commerce platforms or API/Middleware ecosystems.
Technical Stack: Expert-level knowledge of Node.js, Java (Spring Boot), and PostgreSQL - able to read and critique vendor code, not just high-level diagrams.

Data Integration Leadership: Orchestrate complex data mapping between legacy IBM iSeries (DB2/RPG) systems and modern API middleware - a technically demanding challenge requiring deep integration expertise.
Systemic Remediation: Lead deep-dive investigations into recurring platform failures error surges, latency anomalies, and data inconsistencies - and deliver long-term structural remediation, not tactical patches.
Technical Documentation: Maintain high-quality architecture documentation in Confluence, ensuring designs are versioned, accessible, and transferable to operational teams
