    Handle - Portfolio Builder Platform

    A multi-tenant portfolio platform where anyone can sign up, build a professional portfolio and publish it at handleprofile.tech/username. Built end to end and running in production with real users. Users can add experience, education, projects, skills, certifications, testimonials and links, upload a photo, resume and project images, reorder everything with drag and drop, and choose the order of sections on their public page. Each page can be styled with 8 color themes, 4 font pairings and light or dark mode, and prints cleanly as a resume. Every public page also has an AI chat (Gemini API) where visitors can ask questions and get answers based only on that profile, with guardrails against prompt injection, a fallback model, and daily rate limits per account and per hashed IP. Built with Next.js App Router and Server Actions, with ownership checks inside every database query, input validation, a single source of truth for what is public, SEO (sitemap, link-preview images) and a mobile-first dashboard. Released through a QA process with bug tickets, Vercel Analytics and a beta feedback loop.
