Zdenko Vuk

I’m a Senior Full-Stack Developer with 10 years of professional experience building scalable web applications, robust backend systems, and AI-powered solutions.

I combine solid software engineering principles with a practical, product-focused approach. I can take a project from initial architecture through development, integration, testing, and production deployment.

My core expertise includes:

• Frontend Development
• Backend Development
• Databases
• AI & LLM Solutions
• AI Automation
• AI-Assisted Software Development
• Full-Stack Architecture
• UI/UX Implementation

I can help you:

• Build a complete web application from the ground up
• Develop or modernize an Angular, React, Vue.js, or Next.js frontend
• Create secure APIs and backend services with NestJS, Express.js, Django, FastAPI, Spring Boot, or PHP
• Integrate OpenAI, Claude, Gemini, Vapi, Pinecone, and other AI services
• Build RAG systems, AI agents, chatbots, semantic search, and voice assistants
• Use AI-assisted development workflows to deliver features, tests, documentation, and refactoring more efficiently
• Design and optimize SQL, NoSQL, Redis, and vector database solutions
• Integrate external APIs, platforms, and business services
• Diagnose difficult bugs, improve performance, and refactor legacy code
• Turn an early-stage idea into a reliable, production-ready product

I value clear communication, thoughtful architecture, and code that remains understandable long after delivery. I approach every project with ownership and focus on the business problem—not just the next development ticket.
