What I'm looking for

I'm looking to build high-quality, scalable applications where I can use Node.js, React, TypeScript, AI integrations, and clean architecture while collaborating in agile teams.

I've built AI-powered and scalable full-stack applications, including an intelligent recipe platform using NestJS, LLM semantic search, PostgreSQL, Docker, and JWT authentication. I also designed a distributed task-management ecosystem with event-driven microservices and an API gateway.

At Talentus Global, I created PoCs for integrations and an AI framework supporting Azure DevOps file documentation. At Ziora, I optimized React and Next.js interface components, improved navigation performance, and mapped architecture across a large-scale codebase.
