PromptVault - reusable team prompts with reversible PII masking
The challenge
Teams put their best ChatGPT and Claude prompts in private notes. Knowledge disappears, non-technical users cannot run complex prompts safely, and sensitive data leaks into LLM providers.
What I built
PromptVault turns ad-hoc prompts into internal tools: variables become forms, ContextPacks keep tone and glossary consistent, and Privacy Shield masks sensitive values before the prompt reaches an LLM.
It is the pragmatic version of GenAI governance: keep the productivity gain, remove the accidental data leak, and make prompts reusable by the whole team.
Key engineering points
Auto-generated forms from prompt variables for non-technical users.
Reversible PII masking before OpenAI / Claude / Gemini calls.
Shared API for Blazor Web, Chrome extension and VS Code extension.
Workspace, seat and billing foundations for B2B usage.
Similar technical risk?
I can help scope the risk, architecture and first deliverable.
A 30-minute first call is enough to see whether I am the right profile for the problem.

A system like this one to build? Let's talk.
I take on critical technical work — from scoping to production, no debt or lock-in once it's handed over. Fastest way to see if it fits: a 30-minute call.
I reply within 24h — often sooner.
