Got Questions?

Frequently Asked Questions.

Why do you use Google Firebase exclusively?

Firebase provides unparalleled speed, real-time data synchronization via WebSockets, and enterprise-grade security backed directly by Google Cloud infrastructure. This allows our team to build serverless applications that scale automatically from 10 users to 10 million users without ever needing to rewrite the backend or manage physical servers.

How long does a typical project take?

Timelines vary drastically based on scope. A standard personal portfolio can be deployed in 1-2 weeks. Complex Web Applications, Multi-branch POS systems, or E-commerce platforms typically require 4 to 8 weeks depending on the complexity of the custom logic, cloud functions, and design requirements.

Where are you located?

Our executive headquarters are proudly located on Tratman Ave in the Bronx, New York. We service clients locally across the United States and internationally via our globally distributed development team.

Do you offer post-launch support and maintenance?

Absolutely. Every project we deploy comes with a baseline period of free technical support to ensure a smooth launch. After that period, we offer dedicated maintenance retainers to handle framework updates, security patches, scaling adjustments, and new feature additions.
