DeFi and smart-contract engineer with a strong focus on security, architecture, and cross-chain composability. I’ve been building in the blockchain space since 2017 and specialize in Solidity and EVM infrastructure.

Smart-contract engineer: extensive Solidity/EVM experience, including DeFi, AMMs, staking, NFTs, marketplaces and cross-chain infrastructure.

Security-minded engineer: comfortable reasoning about trust boundaries and adversarial behavior.

Systems engineer: comfortable with the off-chain infrastructure surrounding blockchain applications — RPC, indexing, wallets, backend services and frontend integration.

Blockchain interoperability: experience spanning EVM, Bitcoin and Solana, including systems that bridge different execution models.

Protocol engineer: experience going below the application layer (NeonEVM, Bitcoin DLC)

Hands-on senior engineer: experience owning architecture and critical implementation.

Experience as team leader, software architect
 
Worked as a Solidity Engineer at Neon EVM, a Solana network extension that lets EVM dApps deploy on Solana and access its liquidity and user base. As part of a small Solidity team of two engineers I was in charge of the design, development, and security of core infrastructure contracts that enable Neon EVM applications to interact safely with Solana programs (System, SPL Token, Associated Token, Metaplex and others). This work required deep understanding of both EVM and Solana account models, careful authentication and ownership design, and rigorous security considerations.

Contributed open-source work to Atomic Finance’s Bitcoin Discreet Log Contracts stack.
 
Spent over two years as the Lead Software Engineer of the Smart Contracts team at Energi Core, an EVM-compatible proof-of-stake platform. I owned the architecture, security, and delivery of the smart-contract layer powering Energi’s DeFi and NFT products.
 
Built blockchain products at Elementus (blockchain data indexing and forensics API) and Pillar Project (multi-chain wallet infrastructure and encrypted messaging), 
 
I approach every project with an emphasis on quality, security, clear communication, and practical problem-solving. I enjoy leading technical efforts under pressure and mentoring other engineers while staying close to the code. 

I am using AI-assisted development tools such as Claude Code in order to produce boilerplates, brainstorm general architecture considerations and specific parts of the implementation and assist with code reviews.
