02 Experience
Selected work across payments, education, commerce and logistics. Hands-on engineering and team leadership, from understanding the problem to delivering the solution.
Download résumé (PDF)At GlobalLogic (Hitachi Digital Services), part of the team behind a literacy assessment and intervention platform used by thousands of US schools. I design event-driven architectures with Azure Service Bus and Event Grid, build containerized services and lead technical delivery across time zones.
I led the design and implementation of reconciliation infrastructure from the ground up: merchant payment control, transaction auditing and discrepancy detection. The system reconciled hundreds of thousands of card, QR and Pix transactions daily, with traceability and automatic failure recovery. I owned the technical decisions end to end and worked with product and operations to turn regulatory and business requirements into reliable systems.
Part-time consulting on IT team management, feature planning and infrastructure governance. I supported engineering processes and roadmap execution, and managed cloud infrastructure and pipelines through Azure DevOps.
I worked on high-concurrency backend systems and real-time payment processing for a Canadian online grocery platform serving major North American retailers and millions of monthly active users. I led the implementation of risk detection and fraud prevention mechanisms, and supported the team’s delivery cadence as Scrum Master.
Full-stack development for a US platform that helps non-residents incorporate and manage companies. I built and maintained product features with Symfony and Vue.js in a fully remote international team.
I took the operation from paper records to an integrated platform covering tracking, document automation, branches, CRM, warehouse management, last-mile planning and customer onboarding. I also introduced Paraguay’s first subscription model in the freight sector, Sendit Premium. Starting as the first and only developer and later leading the engineering team, I built the platform that supported the company’s growth from zero to nearly 50,000 customers.
