feat: build portfolio homepage v1

[proxynth]

Summary

This PR replaces the default Astro starter with the first public version of the Proxynth portfolio, focused on Senior Backend Engineering.

Positioning

• complex backend systems;
• payments and integrations;
• Go and PHP/Laravel;
• reliability, testing and pragmatic architecture;
• hands-on ownership without management;
• looking for an individual contributor role in a product company.

Contents

• recruitment-oriented homepage;
• concise profile and target-work-environment section;
• Payment Sandbox as the main project;
• LaraWebhook as a complementary open-source project;
• detailed case-study pages for both projects;
• technical approach section;
• dark, minimal and responsive design;
• English page metadata and content;
• links to GitHub and public projects.

Public identity

The site uses Proxynth, the GitHub identity, as its visible public name. The portfolio is intentionally centered on the technical work and repositories rather than personal contact details.

Confidentiality

No proprietary DotWorld project is exposed in this public version. Professional work such as Session Keeper remains reserved for private CV and interview discussions.

CI and deployment

• the existing workflow still deploys GitHub Pages from main ;
• a separate workflow validates pull requests with pnpm install --frozen-lockfile and pnpm build.

Scope

The portfolio is intentionally focused on technical content and projects. It is not a contact page, online CV or LinkedIn redirect.
