Igor Bykowski - Backend and AI Agent Engineering

Hi, I'm Igor Bykowski

Software Engineer from Poland building backend systems and learning production AI agent engineering.

Portfolio LinkedIn Profile views

What I build

Backend systems

Java and Spring Boot services with clean boundaries, SQL persistence, migrations, testing and cloud-native delivery.

AI agent foundations

Agent workflows, tool calling, retrieval, evals and observability for model-powered applications that can be debugged and improved.

Current direction

  • Building toward AI agent engineering: orchestrators, tools, memory, retrieval and human-in-the-loop flows.
  • Designing LLM-ready APIs: structured inputs, typed outputs, recovery hints and safe execution boundaries.
  • Learning production-grade RAG: embeddings, vector search, hybrid retrieval and dataset-driven evaluation.
  • Keeping backend fundamentals sharp: Java, Spring Boot, PostgreSQL, Docker, Kubernetes and AWS.

Stack

Java, Spring, PostgreSQL, MySQL, Docker, Kubernetes, AWS, Git, GitHub, IntelliJ IDEA
