How long does it take to build a website?
Timeline depends on the project scope. A basic website can be completed in 2-4 weeks, while more complex custom applications may take 8-12 weeks or longer. We'll provide a realistic timeline during our initial consultation and keep you updated throughout the entire development process.
Do you offer ongoing maintenance and support?
Yes! We offer ongoing maintenance packages including updates, security monitoring, backups, and technical support. Many of our clients stay with us long-term because we build genuine relationships. We're always just a phone call or email away when you need help.
Can you redesign my existing website?
Absolutely! We work with clients to modernize outdated websites, improve user experience, boost performance, and add new features. Whether it's a complete rebuild or strategic updates, we'll assess your current site and recommend the best approach for your goals and budget.
What technologies do you work with?
We specialize in modern web technologies including React, Next.js, WordPress, Shopify, WooCommerce, Node.js, Python, and various databases (MySQL, PostgreSQL, MongoDB). We choose the right technology stack based on your specific needs, not what's trendy or easiest for us.
Will my website be mobile-friendly?
Yes, every website we build is fully responsive and optimized for all devices — mobile, tablet, and desktop. With most web traffic coming from mobile devices, we design with a mobile-first approach to ensure your site looks great and performs well on every screen size.
