Summary
👤
Senior🎓
Top SchoolDawid Janeczko is a pragmatic senior full-stack engineer based in Austin with about 3 years of formal industry experience and a longer freelance and game-development background that shaped a broad tech toolkit. He delivers scalable web and backend systems using Rust, Java, Node, and TypeScript while building responsive front-ends with SolidJS/React and Web3 integrations. A quick learner and problem solver, he pairs hands-on coding (Postgres, Mongo, Neo4j, AWS, CI/CD) with practical software craftsmanship like unit testing and OOP. His career includes roles at Amazon and leading engineering work at Criggz.com, and his freelance history reflects an ability to move between startup agility and enterprise rigor. Expect someone who quickly adapts to new languages and stacks—he already bridges systems from Solidity smart contracts to Kotlin and C#—and who seeks challenging projects that stretch both backend scale and frontend UX.
