At VORTA S.A.S., I built an agentic WhatsApp bot using the OpenAI API and tool calling to securely read and update PostgreSQL data through a validated tool layer. I also implemented token optimization to reduce LLM cost and latency.
I implemented event-driven communication across three microservices and built background processing with BullMQ and distributed messaging with AWS SQS. Redis caching reduced latency by 35% on average, while PostgreSQL query optimization improved API response times by up to 20%.
At RobotiKids S.A.S., I implemented WebSockets with NestJS for a real-time sales dashboard, cutting API polling requests by 87%. I also implemented a Stripe payment gateway and built event-driven inventory and payment systems.
On ChessMaster, I built a complete chess game and published it on npm as an open-source React component. It includes a five-level AI opponent, full chess rules tested with Vitest, and saved games.
