About

As a senior software engineer with 10+ years of experience in building scalable distributed systems and blockchain protocols, I specialize in Rust-based development for Web3 ecosystems. My work includes launching production networks like Polkadot and Kusama at Parity Technologies, where I contributed to core Substrate frameworks, WASM integrations, and ecosystem tools in Rust and TypeScript. Proficient in designing secure token mechanics, validator logic, and staking systems, I excel in async, open-source environments focused on shipping robust, CI-tested code.

Polkassembly

CTO and Co-founder

Aug 2021 – Present · 4 yrs 7 mos · Berlin, Germany

Founded and architected Polkassembly, Polkadot’s flagship governance platform, enabling on-chain
proposal browsing, community discussions, and direct voting via browser extensions—scaling to
support millions of users in the Polkadot ecosystem.
Implemented Rust-based backend integrations with Substrate for real-time proposal analysis, val-
idator coordination, and staking delegations, including AI-powered tools for data-driven voting and
autonomous execution.
Developed full-stack features using Next.js, TypeScript, and Polkadot.js APIs for secure wallet logic,
key handling, and transaction signing, facilitating decentralized governance flows like challenge-
response for proposals.
Pioneered innovations such as inscription tokens (e.g., Blobscriptions on Polkadot and Avail) and
EVM contract deployments on Kusama, building marketplace functionalities and bridging tools to
enhance token mechanics and subnet interactions.
Led open-source contributions in a contributor-driven environment, managing GitHub issues for CI-
tested simulations on devnet/testnet, ensuring stable, high-TPS performance (e.g., 100k+ Kusama
TPS demonstrations).
Played a key role in addressing security vulnerabilities (CVEs), through diligent analysis and proac-
tive mitigation measures.
Grew the open source organization from 1 to 20 devs.
