As Lead Sylius Developer at ACSEO, I spearheaded the technical overhaul for one of France's leading e-cigarette retailers, ensuring a seamless transition to a robust architecture.

E-commerce architecture & Migration

• Strategic consulting: Defined the technical roadmap to migrate critical data and business logic to Sylius.
• Custom design: Engineered scalable solutions to handle high traffic peaks inherent to the online retail sector.
• Payment modules: Developed and integrated secure payment solutions tailored to the industry's specific regulatory requirements.

Software quality & Excellence

• Testing culture: Implemented a rigorous unit and functional testing strategy to ensure zero regression during migration.
• Quality assurance (QA): Led code reviews and validated Merge Requests to maintain high maintainability standards.
• Continuous deployment: Orchestrated production releases and monitored post-migration performance (Elasticsearch, response times).

Leadership & Agility

• Team leadership: Provided technical mentorship, managed skill development, and hosted "Techlunch" knowledge-sharing sessions.
• Backlog management: Collaborated directly with the Product Owner to prioritize high-value features and secure sprint delivery.
• Process improvement: Continuously optimized the development workflow through regular retrospectives and Scrum methodology refinement.

The primary challenge was to deliver a high-performance, secure e-commerce site capable of supporting continuous growth while simplifying operational management for the client.
