Web App Development for SaaS, Dashboards & Platforms

A website primarily displays information (marketing sites, blogs, portfolios). A web application is interactive — users authenticate, manage data, collaborate, and perform complex workflows (think Notion, Slack, Trello, or Stripe Dashboard). We specialize in building web applications with rich functionality and complex business logic.

We use React and Next.js for the frontend, Node.js with Express or tRPC for the backend, PostgreSQL for relational databases, Redis for caching and real-time features, and AWS or Vercel for cloud infrastructure. We deploy with CI/CD pipelines using GitHub Actions.

Yes. We have extensive experience building multi-tenant SaaS platforms with subscription billing (Stripe), user management with role-based access control, team workspaces, usage-based metering, admin dashboards, and analytics. We handle everything from architecture design to production deployment.

A simple web app takes 2–3 months. A full SaaS platform typically takes 4–8 months. Complex enterprise applications with multiple integrations may take 8–12 months. We recommend starting with an MVP of core features, launching, and iterating based on real user feedback.

A simple web app costs $25,000–$50,000. A mid-complexity SaaS platform ranges from $50,000–$120,000. Enterprise web applications start at $100,000+. Costs depend on feature complexity, integrations, security requirements, and whether you need design services. We provide transparent estimates after discovery.

We implement industry-standard authentication using OAuth 2.0, JWT tokens, and secure session management. We support SSO (SAML, OpenID Connect), multi-factor authentication (2FA), role-based access control (RBAC), and API rate limiting. All data is encrypted in transit (TLS) and at rest. We follow OWASP security guidelines throughout development.

Yes. We implement real-time functionality using WebSockets (Socket.io or native WS), Server-Sent Events, or polling depending on the use case. Common implementations include live notifications, collaborative editing, real-time dashboards, chat systems, and presence indicators.

Absolutely. We regularly integrate with payment processors (Stripe, PayPal), email services (SendGrid, Resend), cloud storage (AWS S3), analytics (Mixpanel, Amplitude), CRMs (HubSpot, Salesforce), and dozens of other APIs. We build robust integration layers with error handling, retry logic, and webhook processing.

For most projects, we recommend starting with a well-structured monolith. It is simpler to develop, deploy, and debug. Microservices add significant complexity (distributed systems, service mesh, inter-service communication) and are only justified for very large teams (50+ developers) or specific scaling requirements. You can always extract services later.

We optimize at every layer: database query optimization with proper indexing, Redis caching for frequently accessed data, CDN for static assets, connection pooling, lazy loading and code splitting on the frontend, efficient server-side rendering, and horizontal scaling with load balancing. We load test before launch to identify bottlenecks.

Yes. We offer maintenance packages that include bug fixes, performance monitoring, security updates, dependency upgrades, database maintenance, and feature development. Web applications require ongoing attention — new browser versions, security patches, growing data volumes, and evolving user needs all require regular maintenance.

Yes. We regularly migrate legacy applications (PHP, jQuery, Angular.js) to modern stacks (React, Next.js, Node.js). We can do incremental migration (strangler fig pattern) or full rewrites depending on codebase condition. We assess the existing system, plan the migration strategy, and execute with minimal disruption to your users.
