What I'm looking for

I'm looking to build scalable AI applications and reliable backend systems, using modern cloud, microservices, and CI/CD practices in Agile teams.

At Tavus, I build Node.js, NestJS, TypeScript, and Python services for AI-powered video generation and real-time conversational experiences. My REST APIs support more than 5 million monthly requests at 99.9% availability, and my OpenAI and LangChain workflows power over 100,000 monthly interactions.

I’ve built RAG features with vector databases, optimized PostgreSQL and Redis-backed microservices to reduce API response times by 35%, and deployed consistent Docker-based services on AWS. I also deliver SEO-optimized Next.js and React applications and contribute to architecture discussions, code reviews, and reliable CI/CD practices.

Previously, I built high-traffic e-commerce platforms at VTEX and MercadoLocal, working across product catalogs, inventory, orders, customer accounts, APIs, and responsive React interfaces.
