Frequently Asked

Custom Web Application Questions.

What tech stack do you recommend for high-performance web apps?

We primarily build with React 19 / Next.js / TypeScript for dynamic interfaces, combined with Node.js / NestJS / Fastify for backends, and PostgreSQL / Redis for database persistence. For static assets and APIs, we utilize Cloudflare edge caching for blazing-fast global response times.

Can you integrate with our existing ERP, CRM, or legacy databases?

Yes. We engineer resilient REST and GraphQL middleware bridges that seamlessly pull and push data to legacy SQL/Oracle databases, Salesforce, HubSpot, SAP, or proprietary custom APIs with automated error retry mechanisms.

How do you guarantee real-time reactivity and sub-second load speeds?

We implement WebSockets / Server-Sent Events (SSE) for instant live data streaming, optimistic UI client updates, intelligent query caching with TanStack Query, and code-split bundle optimization to ensure sub-second interaction speed.

Are your web applications mobile-responsive and offline-capable?

Every web app we deliver follows a mobile-first responsive design philosophy with fluid touch targets. We can also configure Progressive Web App (PWA) offline caching and IndexedDB storage so users can work uninterrupted even during network drops.

How do you secure API endpoints and customer data?

We adhere to strict OWASP Top 10 security standards, including automated rate limiting, CSRF protection, SQL injection prevention, encrypted HTTP-only JWT sessions, and zero-trust API authorization guards.

Can ASMX refactor or take over an existing codebase?

Yes. We conduct a thorough technical audit of your existing repository, identify security and performance bottlenecks, modernize legacy dependencies, and implement structured test coverage without disrupting your live users.
