About this gig
Every time you open a new chat, you're pasting the same brief into ChatGPT or Claude just to get back to where you left off. That means nobody built the prompt - someone typed something that worked once.
I write custom prompts for ChatGPT and Claude, and I build Claude Skills so the working version doesn't disappear when the chat closes. A prompt gets you through today. A Claude Skill remembers your format and rules every time you open Claude, no re-explaining.
I build on the Claude API and MCP daily, so a Claude Skill from me runs the way it's meant to inside your account, not just in a demo.
What you get:
- Custom prompts tuned to your task, tested before delivery
- A working Claude Skill (SKILL.md) built around your real workflow
- Plain documentation your team can actually use
- Before/after comparison on Standard and Premium
If you want five untested prompts fast, there are cheaper gigs for that. This one's for work that still holds up next week.
Tell me your task and I'll tell you straight whether a prompt or a Skill fits. Message me first, or click Order Now.

Your Claude site or app looks great in demo, breaks once someone edits it, no CMS, no live data, no way to update a section without reuploading everything.
I build Claude web apps, landing pages, and MCP integrations that hold up after launch: editable CMS, custom MCP servers for live data, Claude Skill that run the same way every time.
You get a site your team can update, an app pulling real data instead of mockups, fewer emergency fixes. Built production Claude Code sites, MCP servers, and Skills for real launches, not demos.
Send your build, I'll show you what needs fixing, and building.

FAQ
What's the difference between a "custom prompt" and a "Claude Skill"?
A prompt is a single instruction you paste in each time. A Claude Skill is a reusable capability that lives in your Claude account permanently.
Do you work with ChatGPT, Claude, or both?
Both. Custom prompts can be built for either platform.
I already tried building this myself and it didn't work well. Can you fix what I have?
Yes, send what you've already built and I'll test it, tell you what's actually failing, and fix or rebuild it rather than starting over blind.
What do you need from me to get started?
A description of the task or workflow this is for, and 2–3 real examples of what you want the output to look like, if you have any.
Can this scale into an ongoing arrangement?
Yes, Standard and Premium are one-time builds, but if your needs grow (more Skills, more workflows), I'm open to an ongoing retainer for maintenance and additions.
