A mix of custom systems and landing pages I've shipped: marketing sites, billing platforms, digital media, internal tools, e-commerce and podcasts. Different stacks, same goal — code that ships and stays.

Workflow

AI-augmented engineering.

Claude Code is my daily collaborator. Not a replacement for judgement — a tool that removes friction between an idea, production code, and the docs that ship with it. Custom skills, SEO audits, code reviews, refactors: all orchestrated from the terminal.

How I use it

Every task type has its own slash-skill: a template with a checklist, criteria and style that lives in .claude/skills. I invoke /seo-audit to review landing pages, /frontend-design to rework a section, /copywriting to kill AI slop. Result: short iterations, clearer decisions, zero context lost between sessions.
