Veelgestelde vragen
Do you build custom web applications and SaaS platforms?
Yes. We specialize in full-stack web application and SaaS platform development using React, Next.js and NodeJS. We build custom systems from scratch — not templates or page builders. Every project is tailored to your business logic, user flows and technical requirements.
What is your technology stack for web development?
Our core stack is React and Next.js for frontend, NodeJS and Python for backend, and PostgreSQL or MongoDB for databases. We also work with Firebase, Supabase, AWS, Vercel and DigitalOcean for deployment. We choose the right tools for each project rather than forcing every project into same stack.
Can you build a SaaS platform with subscriptions and payments?
Yes. SaaS platform development with subscription billing is one of our core specialties. We integrate Stripe for payments, recurring billing, free trials and subscription management. We also build the admin panel, user roles, and multi-tenant architecture that SaaS products require.
Do you provide backend and database development?
Yes. Our web application development service is fully full-stack. We design and build the backend architecture, REST APIs, database schema, authentication systems, admin dashboards, and all server-side logic your web app needs. You get a complete production-ready system, not just a frontend.
Can you integrate AI features into my web application?
Yes. We integrate OpenAI API, ChatGPT, and custom AI workflows into web applications and SaaS platforms. This includes AI chatbots, document processing, smart search, content generation, and automation workflows. We add AI where it genuinely improves the product and user experience.
Do you build MVPs for startups?
Yes — MVP web application development is one of our core specialties. We help founders define the right scope for the first version, avoid over-engineering, and launch fast. We use React and NodeJS for most MVPs because they give the fastest path to a production-ready full-stack web application.
Will I receive the full source code?
Yes. Every web application and SaaS development project includes full source code handover upon completion. The codebase is clean, documented and ready for your own developers to maintain or extend. We never use no-code tools or templates — everything is custom-built from scratch.
What industries have you built web applications for?
We have delivered web applications and SaaS platforms across SaaS, marketplaces, e-commerce, fintech, real estate, logistics, booking, education, healthcare and internal business tools. We start every project with a discovery phase to understand your users, business model and technical requirements.
How long does web application development take?
A simple landing page or MVP typically takes 1-2 weeks. A full web application with authentication, database and integrations usually takes 4-8 weeks. Complete SaaS platform with payments, admin panel and multi-tenant architecture typically takes 8-16 weeks. We give realistic timelines after review.
Do you offer support after the web app is launched?
Yes. All Premium packages include 30 days post-launch support — bug fixes, adjustments and deployment help at no extra cost. For ongoing maintenance, new features or long-term partnership we offer retainer arrangements. We prefer to be a continuing technical partner, not a one-time vendor.
