Danylo Ostapchenko

I'm an experienced blockchain developer with over 2 years of commercial experience and a solid track record of delivering complex, high-impact projects. My strongest expertise lies in developing advanced Layer 2 solutions for Bitcoin.

I have a strong background in cryptography, which underpins much of my work — from designing secure protocols and signature schemes to working with zero-knowledge proofs and privacy-preserving technologies.

I'm also an active member of the Ukrainian Bitcoin community, regularly attending local meetups and BitDevs sessions to stay engaged with the latest technical developments and research.

Tech Stack & Focus Areas:

• Core expertise: Bitcoin, Ethereum, Solana, DeFi, ZK, protocol design, cryptography
• Rust: My go-to language for low-level and performance-critical blockchain code
• Also fluent in: Golang, TypeScript, Python, and others

At ETHKyiv, I’m excited to meet like-minded builders, contribute to technically challenging ideas, and push the limits of what’s possible in crypto — whether that means hacking, learning, or simply exchanging ideas with some of the best in the space.
