I am a Rust-first fullstack engineer who enjoys owning a product from the database schema to the last pixel. Over the past two years I have designed high-throughput APIs with Actix Web and Tokio, built WebAssembly frontends with Leptos, and deployed everything as containerised services on Linux behind Nginx. I also integrate LLMs (LangChain, OpenAI) into customer-facing workflows, and I care deeply about security: JWT/OAuth, end-to-end encryption, rate limiting and OWASP hygiene are part of my everyday toolkit.
Outside of client work I build things for fun: an end-to-end encrypted chat with WebRTC calling, and a bare-metal x86_64 operating system that boots straight into a calculator.
