About Me
I am a Mobile and Frontend Engineer focused on building practical, reliable applications. My main experience is with Flutter and Dart for cross-platform mobile development, alongside frontend development and backend engineering.
I also work in Bitcoin and Lightning, where I am developing my skills in Rust and Go and learning from real-world open-source projects. I enjoy working across the product stack, from user interfaces and mobile applications to APIs and financial systems.
I am currently involved in products across mobile, web, fintech, and Bitcoin. I care about writing maintainable code, understanding the systems I work on, and building software that solves real problems.
Bitcoin and Lightning are a major part of my current engineering direction. I am building practical experience with Bitcoin wallets, Lightning payments, UTXOs, Rust, Go, and open-source codebases.
I am a Btrust Builders alumnus and have participated in Rust-focused Bitcoin learning. My current interests include Lightning infrastructure, wallet development, Bitcoin developer tools, and contributing to open-source projects.
