Coach HQ
Problem it solves
A role-based coaching platform with fine-grained permissions for admin, coach, content creator, and presenter — covering expert drills with HLS streaming, AI-assisted lesson plans and playlists, webinars, subscriptions, vouchers, and invoice billing.
Overview
Coach HQ is a sports coaching platform built around a single dashboard whose UI — sidebar, actions, and features — resolves from role-based access plus fine-grained permissions for admin, coach, content creator, and presenter. Superadmins run the catalog and operations layer: expert drills (video, PDF, or YouTube) that convert to streaming-ready m3u8 with multi-quality, multi-audio, and multi-caption support; thumbnail picking from video frames; AI analysis that drafts the drill form; premium/free and private/community publishing; lesson plans by week and day with optional AI authoring for admins; playlists; member/non-member webinars with presenters, sharing, cancellation, and recording delivery; coach and creator management; taxonomy; subscription plans and vouchers; transactions and subscribers; newsletters; contact and plan enquiries; roles, permissions, and sidebar configuration; FAQs; app versions; OpenAI API usage; and invoices. Coaches and content creators work inside the same product on their drills, the content library, playlists, manual lesson plans, and Stripe card or pay-by-invoice subscriptions.
I built this as a Full Stack Software Developer at Plex Bit Infosystems (Jan 2026 - Present).
Architecture and technical approach
Video drills convert to HLS (m3u8) for multi-quality playback with multi-audio and multi-caption tracks. AI assists admins with drill form fill, lesson plans, playlists, webinar copy, and final quizzes. Coaches subscribe with Stripe card payments or pay-by-invoice — unpaid invoices revoke access after 30 days unless an admin marks them paid.
Implementation used Next.js, TypeScript, Tailwind CSS, Shadcn UI, Stripe, HLS / m3u8 streaming, OpenAI, Role-based access control, and Fine-grained permissions. The same names appear on the skills page.

Challenges and solutions
Every sidebar item, button, and feature had to resolve from roles and fine-grained permissions, not just the API. Streaming uploads needed m3u8 conversion with multi-quality, multi-audio, and multi-caption support alongside PDF and YouTube sources. AI had to fill drill forms and help build lesson plans and playlists for admins only, while coaches still got full manual authoring. Subscriptions also had to support Stripe card checkout and pay-by-invoice with a 30-day unpaid revoke path that admins can mark paid.
