SOLUTION & SOFTWARE ARCHITECTURE
Design and implement scalable, future-proof architectures for web, backend, and database systems.
From legacy migrations (e.g., Oracle Forms to modern stacks) to greenfield projects, I ensure seamless integration of technologies like Node.js, PHP, React/Vue/Angular, and cloud platforms (AWS, Azure, GCP).
My approach focuses on performance, security, and maintainability, drawing from decades of experience in high-stakes environments like enterprise reporting, e-commerce, and infrastructure automation.
TECHNICAL LEADERSHIP & CONSULTING
Guide development teams as a Technical Lead or Consultant, optimizing processes, mentoring developers, and driving agile transformations.
With certifications in PSM-1 / PSM-2 and upcoming PSPO-1 / PSPO-2, I facilitate Scrum adoption, code reviews, and strategic planning.
I’ve led international rollouts for clients like DB Systel, Vodafone, and Lufthansa, reducing support tickets by 80,000 through intelligent error strategies and fostering collaborative tools like Jira, Confluence, GitLab, and Rocket.Chat.
FULL-STACK DEVELOPMENT & WEB ENGINEERING
Build end-to-end solutions as a Full-Stack Developer, covering
- frontend: React, Vue, Svelte, Tailwind CSS, Material UI
- backend: Express, Laravel, Prisma, GraphQL
Specializing in databases (Oracle, Postgres, MongoDB, Neo4j) and DevOps (Docker, Kubernetes, CI/CD), I create responsive, high-performance applications.
Examples include:
- e-commerce relaunches (XT:Commerce, Magento)
- multi-bank frontends with Selenium automation
- custom platforms like analysis tools for entertainment data
AI COACHING & INTEGRATION
Empower your team with AI-driven development through coaching on tools like Cursor, Claude, ChatGPT, Hugging Face, Ollama, and AutoGen.
I optimize code quality, databases, and workflows, integrating LLMs (Qwen, OpenAI/Claude APIs) into projects for automation and efficiency.
Recent work includes:
- AI-supported portal optimizations for Prague Town Hall
- AI coaching at Pexon Consulting, blending Python, SQL, and machine learning to accelerate innovation in web and enterprise systems.
