About Milan

I am a full-stack web developer with a focus on modern, scalable web solutions – from the digitalization of classic business processes to complex Web3 and crypto applications.

I support companies in achieving their digital goals – whether it's implementing a professional web presence, introducing a high-performance CMS, or completely digitizing internal workflows. With a strong background in CMS and ECM development (including Pimcore certified), I realize tailor-made platforms that are intuitive to use, maintainable, and future-proof.

At the same time, I am deeply rooted in the Web3 and crypto world. As a lead developer and consultant in various DeFi and blockchain projects, I develop high-performance, secure, and user-friendly applications. I integrate wallets, smart contracts, and decentralized data sources – bringing technical expertise and a deep understanding of UX, token economics, and security.

In addition to implementing my own projects – such as Crypto-Castles with over 20 million USD in transaction volume – I have also actively contributed to open-source tools like CosmJS and published online courses for Web3 beginners.

I combine classic web expertise with state-of-the-art blockchain technology. Whether it's a startup, an agency, or a company in transition – I help to implement digital visions reliably, efficiently, and with a high standard of code quality and usability.
