We design and build full-stack web applications — customer-facing products, internal tools, and multi-tenant platforms — with React, Next.js, TypeScript, and solid backend APIs. Every engagement covers architecture, accessibility, SEO, observability, and CI/CD so what ships on day one is ready to grow. We optimize for Core Web Vitals, clean domain models, and codebases your team can own. ## Key Capabilities - **Responsive & Accessible UI**: Interfaces that work across devices and meet accessibility standards without sacrificing design quality. - **Performance Engineering**: Fast first paint, efficient data fetching, caching, and Core Web Vitals tuned for real users. - **SEO & Discoverability**: Semantic markup, metadata, structured data, and rendering strategies that search engines can rank. - **Secure by Default**: Auth, authorization, input validation, secrets management, and dependency hygiene built into the stack. ## Technologies We Use React, Next.js, TypeScript, Node.js, PostgreSQL, Redis, GraphQL, REST APIs, Tailwind CSS, Vercel ## Our Approach 1. **Discovery**: Goals, users, constraints, and success metrics 2. **Design**: UX flows, UI, and technical architecture 3. **Development**: Iterative full-stack delivery with CI/CD 4. **Testing**: Automated and exploratory quality gates 5. **Deployment**: Safe production release and observability 6. **Support**: Post-launch fixes, tuning, and growth work ## Budgets of All Sizes We work with budgets across the full range. The team adapts scope, size, and engagement model to what you can spend, without lowering the bar on how we build. - **Enterprise**: Full delivery teams for complex platforms, with the security, compliance, and process rigor large organizations expect. - **Growing Teams**: Flexible engagements that scale with you. Add capacity when you need it, scale back when you don't, without renegotiating from scratch. - **Small Business & Startups**: Lean, focused builds that get the essentials right. We help you trim scope, not quality, so a modest budget still ships a solid product. ## Why This Matters - **Built to Scale**: Architecture that absorbs traffic and team growth without rewrites every year. - **Faster Experiences**: Snappy interfaces that improve conversion, SEO, and user trust. - **Ownable Code**: Clear structure and docs so your team can extend the product with confidence. - **Lower Risk**: Security practices woven into delivery, not a one-off audit at the end. ## Frequently Asked Questions ### What kind of web applications does OOZOU build?
