I founded PyesaBoss, a start-up that provides a robust, multi-tenant inventory and sales management system specialized for auto parts and accessories. Targeted at auto-parts shop owners in Apalit, Pampanga, the platform empowers multiple separate businesses to operate on a centralized system featuring flexible subscription tiers. It boasts an advanced inventory matrix for accurate vehicle compatibility tracking, a comprehensive POS system equipped with invoice generation, seamless returns and refunds management, and dedicated public storefronts for each shop. Built with a modern tech stack—including Next.js 16 (App Router), React 19, and PostgreSQL with Prisma ORM—the platform is styled using Tailwind CSS v4 and Shadcn UI. Additionally, the entire system is self-hosted on a private VPS using Dockerized containers to ensure optimal performance and control.
