Hands-on software engineer with architectural responsibility. Professional experience across Kotlin, Python, Clojure, Elixir, and TypeScript/JavaScript, proficient in C++ and with working familiarity in Rust.

Experienced with PostgreSQL and MongoDB, as well as event-driven and pub-sub architectures.
Strong grounding in algorithms, software architecture, and the full software development lifecycle, applying practices such as domain-driven design, test- and behaviour-driven development, and infrastructure as code.
