@piotrnovak

Senior AI and full-stack engineer at Devjam who improved production performance by approximately 35%.

At Devjam, I engineered full-stack product features with React, TypeScript, Node.js, REST APIs, and PostgreSQL. I designed application flows for LLM-backed assistants, document retrieval, and structured output processing.

I built reusable frontend components across 15+ production features and optimized rendering, APIs, and database access, contributing to approximately 35% performance improvement. I also improved resilience through incident investigation, API validation, logging, containerization, automated testing, and CI/CD.

At WolkSoftware, I developed React and TypeScript interfaces and Node.js services across 20+ screens and workflows, and extended products with AI integration patterns. Earlier, at MobileReality and Iqcode, I delivered web and mobile application features, API integrations, and database-backed services.
