How long does it take to build a web app?

A functional prototype (MVP) takes 2 weeks. A full production-ready web app typically takes 4-8 weeks depending on complexity. Enterprise projects are scoped individually. We always agree on timelines before starting.

Do you build mobile apps for both iOS and Android?

Yes. We build cross-platform apps using React Native when it makes sense for budget and timeline, and native apps when performance requirements demand it. Every app goes through our quality process before App Store submission.

What does a Technical SEO Audit include?

A comprehensive analysis covering Core Web Vitals performance, indexing and crawlability, site architecture, semantic HTML structure, mobile usability, security headers, and structured data. You receive a prioritized action plan with estimated impact for each recommendation.

Can you work with our existing website or do we need to rebuild?

Both. We can audit and optimize your existing site, or rebuild it from scratch if the technical debt makes optimization impractical. We always recommend the most cost-effective approach based on your goals and current state.
