With over 9 years of professional experience in software development, I specialize in building end-to-end blockchain applications that are secure, scalable, and production-ready. Originally from Poland, I’ve worked with clients worldwide to deliver innovative Web3 solutions that power the next generation of decentralized technologies.
I'm an expert in smart contract development using Solidity for EVM-compatible blockchains (Ethereum, BNB Chain, Polygon) and Rust for Solana. I write clean, efficient, and audited code that ensures performance, security, and cost-effectiveness.
I’ve successfully launched and maintained several blockchain-based platforms, including:
* Binary options trading dApps
* Decentralized sports betting apps
* Custom DeFi protocols with complex logic and reward mechanisms
Alongside blockchain, I’m also a full-stack developer with solid experience in:
* Frontend: React.js, Next.js
* Backend: Node.js, Django
* Databases: MongoDB, PostgreSQL
* DevOps & APIs: Docker, RESTful services, Firebase, and Web3 integration
Whether you need to:
* Launch a dApp on Ethereum or Solana
* Build a crypto payment or staking system
* Connect smart contracts with your web app
* Design responsive frontends for Web3 platforms
* Or develop secure APIs for your blockchain infrastructure
I’m here to help turn your vision into a working product.
Let’s build something great together — I bring technical expertise, attention to detail, and a strong work ethic shaped by a decade of hands-on development experience.
