What technologies do you use for custom web applications? We work with modern frameworks such as React, Next.js, Angular, and Astro, choosing the stack based on performance, maintainability, and integration needs. Can you integrate existing databases or legacy systems? Yes. We can connect existing MySQL, PostgreSQL, legacy, and modern database systems, or help migrate and modernize the data layer. How secure are the applications? Security is planned into the build with authentication, permissions, encryption patterns, validation, and secure coding practices. Can you connect third-party APIs? Yes. We integrate payment gateways, CRMs, ecommerce tools, marketing platforms, analytics systems, and other APIs that support the workflow. Do you develop mobile apps? Yes. We build iOS, Android, and cross-platform mobile apps using technologies such as Flutter and React Native when they fit the project. How much does a custom app cost? Pricing depends on scope, complexity, integrations, workflows, and required support. We define a practical scope before recommending a build path. ## More of our services. ![Website route system connecting content, ecommerce, and conversion paths](https://www.micromarketing.dev/images/optimized/ai-og-image-480.webp)Site layer ### Website Development Fast, responsive, conversion-first websites that connect to your app and integration layer.
