Software Engineer & Founder

Hi, I'm Wiktoria.

I build across Web2 and Web3 - from financial systems at JPMorgan to smart contracts on Solana, and now WellKey, an AI burnout detection startup.

About me

Engineer by training,
founder by experience.

I studied Computer Science with Spanish at the University of Aberdeen, graduating First Class with a dissertation on Solidity vs Rust in smart contract development. I worked as a Software Engineer at JPMorgan in Glasgow, migrating legacy financial systems into modern microservice architecture. Then I burned out.

That experience redirected me. I started building WellKey - an AI burnout detection platform for companies - because I knew the problem from the inside. I'm also active in the Web3 space, having worked as a smart contract engineer on cross-chain systems (EVM and Solana) and won bounties at ETHGlobal, ETHWarsaw, and ZKHack Berlin.

I'm a traveller at heart. Every country I've visited has shaped how I think and build. I reflect constantly and believe personal development is a practice, not a buzzword. Bilingual in Polish and English, with intermediate Spanish.

World citizen

Poland born, Scotland educated, travelled widely. Every country leaves something behind in how I think and build.

⛓️

Web3 builder

Smart contracts in Solidity and Rust, cross-chain systems, ZK proofs, hackathon bounties. Comfortable across EVM and Solana.

Full-stack engineer

JPMorgan, XSwap, freelance - I own the full stack. Both parents run their own businesses; entrepreneurship runs in the family.

Reflective founder

Burned out, bounced back, now building the tool I needed. Personal development is not just a theme - it's my origin story.
