š Hello!
I'm Tom Seidel, a freelance consultant with over 20 years of experience in Java development. My focus lies in designing and implementing sophisticated software solutions ā from traditional desktop applications to modern, containerized web applications in the cloud, and increasingly AI-powered agentic systems.
As both a developer and architect, I support projects end-to-end: from the initial concept and architecture to production-ready implementation. In recent years, I've specialized in cloud technologies and AI integration, helping companies successfully launch new Java-based cloud projects, migrate existing monolithic systems to scalable microservice architectures, and build intelligent agentic workflows ā leveraging modern DevOps tools, LLM APIs (Anthropic, OpenAI, Ollama, llama.cpp), and cutting-edge AI methodologies.
My goal: to deliver sustainable, maintainable, and high-performance software solutions that create real value.
Mission
To empower businesses by delivering robust, scalable, and future-proof cloud-native solutions using modern Java technologies and AI-driven automation ā ensuring agility, performance, and long-term maintainability.
