I build AI-powered applications and tooling that makes teams faster, applications that hold up, and tools that remove the tedious parts of the job.
I have full professional working proficiency in Chinese (DLPT5 3/3), Finnish at B1 and Swedish at A1. That global perspective translates into frontend work that spans cultures: internationalization, timezone-aware interfaces, and datetime handling that works across regions and calendar systems.

My projects run on shared AI workflows I maintain: repo-level agent instructions, plus skills and subagents for research, test-driven development, code review and commit messages. Linting, formatting, type-checking and tests run as gates in CI and in the agent loop, and the same gates apply to my commits and to anything an agent produced. Nothing ships that I haven’t read.

I treat discoverability as part of the build, not an afterthought.
I target the highest level across every project to make sure the broadest possible audience can use and navigate everything I build.
Frontend architecture, backend services, databases and payments. I work across the stack. Let’s talk.
