At CIC Controle, I migrated a legacy IAM v1 API to a secure v2 platform, replacing its authentication flow with a centralized, containerized identity layer using Keycloak. I implemented SSO/MFA, audit-compliant user action tracking, and structured observability.
I also built automated tests with nearly 100% coverage using in-memory MongoDB environments, and carried out deep legacy refactoring and schema-versioned migrations. I used Anthropic Claude Code agents to help generate tests and synchronize contracts across repositories.
At Shaw and Partners, I migrated a multi-repository architecture to a monorepo and moved the frontend build setup from Webpack to Vite, reducing build and reload times from 2 minutes to 100 milliseconds. I also developed a PDF generation microservice on AWS and optimized a synchronized React map interface for mobile devices.
