Open-source CLI that generates fake data and structured mock payloads for development, QA, UI demos, dashboards, and CMS prototyping. Built around three commands (generate, config, fill) with strict Zod validation, configurable catalogs, and fully offline execution, so no data leaves your machine.

• Designed a subcommand API (generate, config, fill) with aliases and a default generate command for fast everyday use

• Generates 20+ data types across identity, network, numeric, content, and persona outputs

• Added a fill command with dry-run mode for reusable payloads in scripts and CI pipelines

• Built local config management with field toggles and custom catalogs

• Enforced type-safe contracts and strict input validation with Zod on every command

Web learning platform that turns structured content into interactive study sessions: topic summaries, memory aids, and quizzes. It starts with DGT Class B driving-theory prep and is built to expand into other subjects. Not an official DGT guide.

• Architected a modular Astro, TypeScript, and Tailwind CSS app built to grow into new learning domains

• Designed a normalized JSON content model for topics, mnemonics, exam tips, and question banks

• Built responsive, accessible study and quiz interfaces for desktop and mobile

• Mapped content to reusable UI patterns, so new topics ship without new components

• Built a reusable, accessible component system with automated checks in Biome and GitHub Actions
