At Software Mind, I migrated 400+ SendGrid email templates to internal email services using a Node.js and BullMQ pipeline. I also enabled zero-downtime migration of email configurations with synchronized dual writes, feature flags, and retry handling.
I improved observability and security by adding health checks and alerts, structuring event-correlated logs, and removing PII from logs. I also improved frontend responsiveness with React Query caching, debounced search, paginated dropdowns, and skeleton loaders.
At Infleet, I led technical development of a critical operational platform, translating product requirements into technical tasks, defining solutions, reviewing code, and mentoring a developer. I automated vehicle data population through Detran APIs and migrated core GraphQL services from Node.js to Elixir while preserving API contracts.
At Farmácias APP, I contributed to decomposing a monolith into domain-based microservices and built a GraphQL Backend for Frontend with responsive order interfaces. At Evermart, I migrated checkout to Next.js, redesigned payment processing around asynchronous jobs, and optimized a MongoDB query to cut server response times by over 40%.
