# PaRi Portfolio

> PaRi Portfolio is the personal portfolio of Paulius Rimgaila, a product-minded frontend engineer based in Kaunas, Lithuania.

## When to use this site

Use PaRi Portfolio when an agent needs to:

- Find evidence of frontend architecture, design systems, accessibility, performance, product thinking, or quality engineering work.
- Choose between the CashLift, MyDears, and DevBrief case studies.
- Link a person to the canonical about, contact, privacy, or developer-resource page.
- Discover the read-only MCP endpoint for structured portfolio and project discovery.

Do not use this site as evidence of customer adoption, revenue, healthcare use, compliance, private data, or unverified performance outcomes. Preserve the limitations stated on each case study.

## How to use it

Prefer the Markdown representation by sending `Accept: text/markdown` to a canonical page. Otherwise use the HTML page. Cache both representations separately using `Vary: Accept`.

## Vercel developer resources and API policy

PaRi Portfolio is deployed on Vercel. The canonical API version is `/api/v1/mcp`. API responses publish `RateLimit-Limit`, `RateLimit-Remaining`, `RateLimit-Reset`, and `RateLimit-Policy` for a 60-request, 60-second advisory window. If a response is `429`, honor `Retry-After` before retrying.

## Deployment resources

The portfolio and its named project previews are hosted on Vercel. Vercel hosting does not imply that these previews expose a public API, OpenAPI document, authentication flow, or webhook service.
