My daily work includes: - Conceiving, implementing, maintaining and optimizing key group solutions (backend, frontend, microservices, infrastructure, automation, payment systems) - Organizing and offering technical insights/analysis in projects: needs, specs, team sizing and coordinating teams (priorities, work distribution, coordination, communication). - Sharing good practices, processes and knowledge to devs while facilitating their work and improving their productivity by upgrading processes and technical environments. Some examples: - Migrated 5 countries' e-commerce websites into a common system with their own specific features/legal requirements leading to 10 points increase in conversion rate globally. - Implemented architecture as code solutions and pipelines to ensure consistency/visibility of key structure and data changes in systems used by 5+ teams drastically reducing regressions, rollbacks and improved time to market. - Implemented out of the box toggle-able multi-currency payment with multiple providers, payment methods with an unified refund system. - Optimized performance (queries, computation, memory management) and stability across multiple stacks and systems: first year without production issue during peak periods. - Leading evolutive and curative maintenance projects on multiple stacks to reduce tech debt, security risks and improve both performance and productivity. - Leading documentation and knowledge sharing efforts: implementing coding and PR standards, documentation templates, organizing knowledge sharing sessions. - Simplifying, unifying and improving stacks to improve tech users' experience.
