Web Applications: Custom SaaS, CRM & ERP
Complex web applications built to scale. CRM systems, ERP platforms, SaaS products, admin dashboards, client portals, we architect and build the tools your business needs to operate efficiently. Our applications handle thousands of concurrent users, process real-time data and integrate with third-party APIs. We use React for responsive frontends, Node.js for scalable backends, and PostgreSQL for reliable data storage.
What we do
How we work
System Architecture & Planning
We design scalable architectures using microservices patterns, RESTful APIs and event-driven communication. Database schema design with proper indexing, relationships and query optimization. Authentication and authorization with JWT tokens, role-based access control (RBAC) and multi-tenancy support. Infrastructure planning with Docker containerization, load balancing and horizontal scaling strategies. Security-first approach with input validation, SQL injection prevention and XSS protection.
Frontend Development
React-based single-page applications with real-time data updates via WebSockets. Complex data visualization with Chart.js and D3.js, dashboards, reports, analytics and KPI tracking. Form management with validation, multi-step wizards and file uploads. State management with React Context or Redux for complex application state. Responsive layouts that work on desktop, tablet and mobile. Dark mode support and accessibility compliance.
Backend & API Development
Node.js and Express APIs with PostgreSQL, battle-tested, performant and maintainable. RESTful endpoint design with proper HTTP methods, status codes and error handling. Database migrations and seeding for version-controlled schema changes. Background job processing with Bull queues for email sending, report generation and data processing. Third-party integrations: payment gateways, email services, SMS, cloud storage, Google APIs, social login. Comprehensive API documentation with Swagger/OpenAPI.
DevOps, Testing & Deployment
Docker containerization for consistent development and production environments. CI/CD pipelines with automated testing, linting and deployment. Zero-downtime deployments with rolling updates. Automated database backups with offsite storage. Server monitoring with uptime alerts, error tracking and performance metrics. Staging environments for safe testing before production. Load testing to verify performance under expected traffic. Post-deployment monitoring and rapid incident response.
Full Web Development: From Idea to Live App
End-to-end web development for companies that need more than a website: custom web application development, integrations with existing systems, internal portals and automations. We work as a partner web developer, not a one-off vendor, from the first wireframe to the live app and its maintenance.
