Summary
👤
Senior🎓
Top SchoolDavid Lepaux is a Senior Lead Frontend Engineer based in Geneva with over a decade of experience building full-stack web products for luxury, sports, media, and e-commerce clients. He combines hands-on frontend expertise (Next.js, Storybook, Vanilla Extract) with systems-level work—designing microservices, migration scripts, and autoscaling architectures on AWS—to deliver performant, production-grade platforms. As founder of SQLI’s Innovation Hub he turns consultant bench time into R&D, leading generative and sovereign AI initiatives to boost developer productivity and build IDE-integrated assistants. He has led large-scale migrations (2M+ assets to Cloudinary, 1000+ funnels from Agora) and reduced platform costs and load times through pragmatic engineering and automation. A pragmatic technical leader and mentor, he modernizes legacy stacks while shipping user-facing features and developer tooling that measurably improve delivery speed. Non-obvious strength: he pairs product-minded thinking with pattern-driven implementations (Observer/Strategy, RAG, background job batching) to optimize both UX and operational efficiency.
