Web Application Development
Full-stack web applications built with modern technology, designed for scale, and engineered to last.
A web application is not a website. It is software that runs in the browser — complex, interactive, and critical to your business. Whether you are building a SaaS platform, a customer portal, an e-commerce system, or a specialized business tool, the quality of the engineering determines whether your product delights users or frustrates them.
We build custom web applications for businesses that have outgrown off-the-shelf solutions. Our stack — React with Next.js on the frontend, Node.js with TypeScript on the backend, PostgreSQL for data — is chosen for reliability, performance, and the depth of the available talent pool. No exotic frameworks that make hiring difficult, no bleeding-edge tools that break on updates.
Every project is built with the same standards: type safety throughout, comprehensive testing, automated deployments, and documentation that makes the codebase accessible to any competent developer.
What You Get
Full-Stack Development
React frontend + Node.js backend + PostgreSQL database — a cohesive application built by a single team with consistent patterns and shared TypeScript types.
Authentication & Multi-Tenancy
Secure user management with Clerk or Auth0, role-based access control, organization/team structures, and data isolation for multi-tenant SaaS applications.
Payment & Billing
Stripe integration for subscriptions, usage-based billing, one-time payments, invoicing, and customer portal — handling the full billing lifecycle.
Transactional Email
Automated emails for onboarding, notifications, receipts, and alerts using SendGrid or Resend with templated, branded email designs.
Admin & Back-Office
Administrative interfaces for managing users, content, configurations, and business operations — built alongside the customer-facing application.
Performance & SEO
Server-side rendering, image optimization, code splitting, and Core Web Vitals optimization for applications that need to be fast and discoverable.
Our Technology Stack
We use a consistent, modern technology stack across all web application projects. The frontend is React with Next.js, providing server-side rendering for SEO and performance, file-based routing for simplicity, and API routes for backend-for-frontend patterns. Styling is done with Tailwind CSS for rapid, consistent UI development.
The backend runs on Node.js with TypeScript, using Fastify or Express for HTTP handling and Prisma for database access. PostgreSQL is our default database, chosen for its reliability, feature set (JSON, full-text search, GIS), and the maturity of its tooling. Redis handles caching, sessions, and job queues.
This stack is not chosen because it is trendy — it is chosen because it works at scale, has excellent developer tooling, a massive talent pool for future hiring, and has been battle-tested across thousands of production applications.
Building for Scale from Day One
Premature optimization is a real problem, but so is premature architecture. We design applications to handle 10x your current load without architectural changes — not because you will need it tomorrow, but because the cost of building it right from the start is marginal compared to the cost of a rushed re-architecture later.
This means: stateless application servers that can scale horizontally, database schemas designed with proper indexes and query patterns in mind, background job processing for anything that takes more than 200ms, and caching at the appropriate layers. These patterns add minimal development time but provide enormous breathing room as your application grows.
For SaaS applications specifically, we implement multi-tenancy patterns, subscription management, usage tracking, and feature flagging as foundational infrastructure — not afterthoughts that need to be retrofitted later.
Quality Assurance and Ongoing Support
Every web application we build has a comprehensive QA process. Automated tests (unit, integration, and end-to-end with Playwright) run on every pull request. Before launch, we conduct accessibility audits (WCAG 2.1 AA), performance audits (Core Web Vitals in green), security reviews (OWASP top 10), and cross-browser testing. After launch, we monitor error rates with Sentry and set up alerting for anomalies.
Launching a web application is the beginning, not the end. The most successful products iterate continuously based on user feedback, usage data, and business requirements. We offer ongoing development retainers for feature development, bug fixes, and performance optimization. For teams that want to bring development in-house after launch, we provide thorough handoff documentation and onboarding sessions for your development team.
