Web Development Questions

Everything you need to know before building with Rincetech.

What technologies do you use for web development?

We build with modern, production-proven stacks: React, Next.js, and TypeScript on the frontend; Node.js, Python (Django/FastAPI), and microservices on the backend; PostgreSQL, MongoDB, and Redis for data; and AWS, Vercel, or Docker/Kubernetes for hosting. We pick the right stack for your goals, budget, and scale.

How long does it take to build a web application?

A marketing website typically takes 2 to 4 weeks, while a full-stack web app or SaaS product usually takes 6 to 16 weeks depending on features. We work in agile sprints with weekly demos so you see progress continuously and can adjust scope as we go.

Do you provide ongoing maintenance and support?

Yes. We offer flexible maintenance retainers covering security updates, performance monitoring, bug fixes, new features, and uptime support so your application stays fast, secure, and reliable long after launch.

Can you build SEO-friendly, high-performance sites?

Absolutely. We build with clean code, server-side rendering, image optimization, and Core Web Vitals best practices — and our in-house digital marketing team can take it from launch to the top of Google.

Do you build mobile apps too?

Yes. We build cross-platform mobile apps with React Native and Flutter, plus installable Progressive Web Apps (PWAs) that work offline and feel native — all sharing one codebase and backend with your web platform.
