Frequently Asked Questions About San Francisco Web Application Development

Our core full-stack stack centers on React and Next.js (App Router, Server Components) for reactive, SEO-ready frontends, coupled with Laravel (PHP 8.3+) or Node.js/TypeScript for robust, secure backends. For data storage, we utilize PostgreSQL, MySQL, and Redis, deployed on AWS, Vercel, or modern containerized cloud infrastructure.

You maintain 100% exclusive ownership of all code, database schemas, API architecture, and digital assets. Work is developed directly in your private GitHub or GitLab repositories, governed by standard US-compliant IP assignment and bilateral NDA agreements.

A standard Production MVP typically takes 8 to 12 weeks from technical scoping to staging deployment. We break development into two-week agile sprints featuring user authentication, payment processing (Stripe), role-based permissions, and core domain features, complete with weekly video demos.

Yes. We specialize in legacy system modernization. We incrementally decouple monolithic codebases into modular API services, migrate legacy databases to PostgreSQL/MySQL 8, upgrade deprecated backend versions, and rewrite slow interfaces with modern React frontends without business interruption.

We provide a guaranteed daily synchronous overlap window from 9:00 AM – 1:00 PM Pacific Time (PT). Your founders, product managers, and engineers communicate directly via dedicated Slack channels, Jira/Linear tickets, and interactive sprint retrospectives.

Yes. Every client engagement begins with a standard mutual NDA protecting proprietary business logic. We follow strict US compliance best practices, implementing SOC-2-aligned RBAC access controls, AES-256 database encryption at rest, TLS 1.3 in transit, and secure secret vault management.
