FAQ

Frequently Asked Questions

How long does it take to build a web application?
Timelines vary based on complexity. A simple MVP takes 4-8 weeks, while a full enterprise platform can take 3-6 months. We provide a detailed timeline during the discovery phase.
What technologies do you recommend?
We recommend technologies based on your specific needs. For most projects, we use React or Next.js for frontend, Django or Node.js for backend, and PostgreSQL for the database. We choose the best stack for your use case.
Do you provide ongoing maintenance?
Yes. We offer maintenance packages that include bug fixes, security updates, performance optimization, and feature additions. Most clients choose our monthly retainer for continuous support.
Can you work with our existing codebase?
Absolutely. We can audit your existing code, identify issues, and gradually improve or refactor it. We also handle migrations from legacy systems to modern frameworks.
How do you ensure security?
Security is built into every stage. We follow OWASP guidelines, implement encryption, perform regular security audits, and run penetration testing before deployment.
What about post-launch support?
We provide 30 days of free post-launch support for any critical issues. After that, we offer monthly maintenance plans or on-demand support as needed.
