At Calindra @ Carrefour, I cut product, offer and stock update time by 57% on a pipeline handling 3M+ items a day. I designed a Redis debounce layer that collapsed redundant events and eliminated VTEX HTTP 429 spikes.
At the US-Based AI Cybersecurity Startup, I built a Go authentication microservice supporting LDAP, OIDC and JWT for on-premise clients. I also designed RabbitMQ event processing and enabled deployments across CPU, NVIDIA GPU and hybrid hardware.
At Congenial, I redesigned the onboarding flow, increasing new-student conversion by 15–30%, and helped scale the learning platform to 10,000+ registered students. My work included building admin screens and gamification, integrating payments, and teaching algorithms and data structures in C++.
