Unlike a brochure website, a web application lets users log in, manage data and complete workflows. Gamostar is a web app development company building multi-tenant SaaS products, customer and partner portals, booking systems, admin dashboards and internal tools.
Our engineers use React / Next.js, Node.js or Laravel, PostgreSQL / MongoDB and cloud infrastructure, with role-based access, audit logs, APIs, tests and CI/CD. We start with a clear scope and ship in short sprints so you see working software early.
Multi-tenant architecture, subscriptions, billing and usage analytics.
Role-based portals with reports, exports and notifications.
REST / GraphQL APIs and integration with CRM, ERP and payment systems.
AWS / GCP / Azure, Docker, CI/CD and monitoring.
OWASP practices, encryption, SSO and audit trails.
