About xymgsb1
I am a full-stack developer with experience building SaaS-style web applications, admin systems, CRM platforms, and backend APIs. My current projects include a front-end/back-end separated SaaS CRM Admin System built with React, TypeScript, Vite, Ant Design, Zustand, Node.js, Express, Zod, and Prisma Schema. The system covers customer management, orders, contracts, payments, users, roles, permission templates, and notifications. I can work across frontend, backend, API design, database modeling, and system architecture. I also have experience with C#, C, Linux environments, and low-level/network-related development. I am interested in collaborating with founders, solo builders, and teams who need reliable technical execution for SaaS products, internal tools, dashboards, admin panels, CRM systems, and backend services.
