Frequently Asked Questions
Clear answers regarding our software engineering standards, IP ownership, sprint velocity, and SLA guarantees.
Next.js 16 App Router provides unrivaled SEO performance, sub-second Core Web Vitals, and streaming SSR for web platforms. Flutter allows us to build native-fidelity iOS and Android mobile apps from a single codebase with local SQLite caching, biometric security, and 60fps animations.
A typical MVP project takes 4 to 8 weeks from technical discovery to production release. Larger enterprise platforms with complex microservices span 8 to 16 weeks, organized into transparent 2-week agile sprints with bi-weekly staging demos.
You own 100% of the source code, design assets, database schemas, cloud infrastructure, and intellectual property. All Git repositories and cloud credentials are transferred directly to your organization upon milestone sign-offs. There is zero vendor lock-in.
Connected Hood is our flagship PropTech platform serving gated communities and property managers. It combines AI multilingual notices, biometric gate security, automated maintenance billing, and resident helpdesk management with 99.9% uptime SLA.
We offer two flexible models: Fixed-Scope Milestone Pricing (ideal for well-defined MVPs and product launches) and Dedicated Agile Engineering Squads (ideal for scaling companies requiring continuous sprint velocity and dedicated senior engineers).
All software architectures follow OWASP Top 10 guidelines, role-based access control (RBAC), end-to-end TLS 1.3 encryption, secure database parameterization, and strict secret isolation in compliance with modern data privacy standards.
