A French ski-chalet marketplace rebuilt on Symfony while it kept selling: legacy data and business logic moved first, then a new search engine behind caching, query optimisation and on-demand WebP images. I built the core solo from April 2025, then led a team of four to delivery in July 2026.
10,000+ chalets · search 20–50 s → 4–6 s · 390+ tests · ~60% less image bandwidth
