Mentoring
Large applications eventually accumulate complexity: legacy code, slow builds, performance problems, architectural compromises and difficult product requirements. This is the kind of environment I enjoy working in.
I design, build and improve complex production applications. My strongest expertise is frontend engineering, but I am comfortable working across the stack when a problem requires it.
I actively use coding agents in day-to-day engineering work — from codebase exploration and implementation to refactoring, debugging and review. I also helped introduce Claude Code and agent-based workflows within my development team.
Long-term work on performance, build tooling, dependency modernization and developer experience in a large production application.
Gradual migration of a large production interface from a legacy iframe/Vue architecture to Nuxt without stopping ongoing product development.
Development of a new research methodology across data structures, backend logic, validation and a complex interactive frontend.
