Geoffrey Monte is a Senior Backend Developer with 13 years of experience specializing in PHP and Symfony, currently consulting and building resilient backend systems from Lille, France. He combines hands-on engineering and technical leadership—having led migrations, custom ERP builds and ecommerce integrations—while modernizing infrastructures with Docker, AWS/GCP, CI/CD and message-driven architectures. Comfortable in international, agile teams, he has driven financial and travel backends (payments, currency flows, booking systems) and experimented with AI agents to automate internal processes. As a long-time freelancer and founder, he pairs product-focused pragmatism with a knack for translating complex domain needs into maintainable, scalable services. An ability not immediately obvious: he repeatedly takes legacy platforms from Symfony 2.x to modern stacks while keeping business continuity during high-growth or high-availability operations.
