About
I’m a BSc Software Engineer with a degree in Software and Information Engineering from Singidunum University. I have solid experience across the stack: JavaScript / TypeScript (React, Node.js) and Java (Spring) for backend solutions. Currently deep-diving into Next.js for modern, high-performance web development.
I’m open for collaboration on full-stack web apps, AI / chatbot systems, data-driven solutions, and open-source contributions.

What I do
Capabilities
A small set of things I do well: the stack, the polish, and the engineering instincts I bring to every project.
Full-stack web apps
End-to-end delivery with React, Next.js, Node.js, and Java Spring. Type-safe APIs, clean data models, and UI that ships.
AI & chatbot systems
Conversational assistants and data-driven features built on Rasa, Python, and modern LLM tooling.
Performance & scale
Fast Core Web Vitals, thoughtful caching, and SQL / NoSQL schemas that hold up as the product grows.
Dev experience
Readable code, strict TypeScript, CI on every push, and accessibility taken seriously by default.
