I'm a blockchain developer passionate about privacy-preserving systems, smart contract infrastructure, and scalable backend design. Based in Warsaw, I focus on building secure and efficient systems using zero-knowledge proofs and cryptographic primitives.
- Designing a zk-SNARK-based voting protocol using Circom, Groth16, Solidity, and Rust
- Built custom ZK circuits for Merkle inclusion, nullifiers, and vote logic
- Working on decentralized verifiability and ZK-based election integrity
- Built a real-time blockchain explorer supporting 20+ networks (Python, Django, Celery)
- Developed secure wallet infrastructure with hot/cold custody and key management
- Implemented EIP-4337 account abstraction with smart contract wallets and gas paymaster contracts
Languages: Python, Rust, Solidity, Circom
Smart Contract Tooling: Django, Hardhat, Foundry, Truffle, Ethers, Web3
Blockchain & Cryptography: Ethereum (EVM), zk-SNARKs (Groth16), Merkle Trees, Privacy-Preserving Protocols
Backend Development: Django, FastAPI, Celery
Data & APIs: PostgreSQL, TypeORM, Redis, REST, WebSockets
Infrastructure & Monitoring: Docker, Git, CI/CD pipelines, Sentry, Pytest, Unittest
Soft Skills: Clear communication, structured problem-solving, ownership mindset
