Je ferai la personnalisation et l'intégration API avec vtiger

I integrate APIs, build web apps, and solve complex problems, without breaking what already works. In 15 years I have delivered over 200 projects for clients in the US, UK, Canada and Australia, mostly in Rails, Node, Laravel, React and AWS. What I am asked for most: - Third-party API integrations: payments, CRM, logistics, marketplaces - AI in existing apps: OpenAI, Claude, RAG search, automation - Fixing AI features that give wrong or inconsistent answers - Reducing AI API costs - Shopify apps and theme development Tell me what you are building and where it is breaking.
