What I'm looking for

I'm looking to solve meaningful technical problems while working closely with clients to understand their business and emotional needs.

I've built Cardano smart contracts and worked with Substrate and SQL queries for a DB-Sync indexer at BinarApps.

Previously at IC Solutions, I developed REST and SOAP APIs, automated biometric-signature verification, and created a DSL for mapping XML data into PDF documents. My work spans Haskell, C#, Rust, Clojure, Elixir, and blockchain platforms including Cardano, Polkadot, Canton, and Ethereum.

Mathematics has been my greatest passion for as long as I can remember, connecting practical computer science with theoretical philosophy. I bring that curiosity to solving both technical and client problems.

Over time, I've learned that understanding clients' emotional and business needs is essential to delivering effective solutions, not separate from engineering work.
