Frequently Asked Questions

Everything you need to know about working with us. Still have a question? Reach out via the contact form below.

A focused MVP usually takes 4–8 weeks, while a full enterprise platform can span 3–6 months. After a discovery call we provide a detailed sprint plan with clear milestones so you always know what to expect.

We offer flexible support plans including 24/7 monitoring, priority bug fixes, performance optimization, and feature enhancements. Every engagement includes a warranty period after launch, and you can extend support through a tailored monthly retainer.

Yes. We routinely take over legacy codebases, modernize them, and provide ongoing maintenance. We start with a code audit to identify risks and quick wins, then propose a maintenance roadmap that fits your budget and release cadence.

Our core stack is React, Node.js, Express, and MongoDB/PostgreSQL, plus React Native and Flutter for mobile. We also work with AWS, Docker, Kubernetes, and modern AI/ML frameworks. We always recommend the technology that best fits your specific problem.

Pricing is based on scope, complexity, and timeline. We offer both fixed-price engagements for well-defined projects and dedicated-team models for evolving scopes. You receive a transparent quote upfront with no hidden fees, and we track budget weekly.

Security is built in from day one: secure coding standards, dependency scanning, OWASP-aligned reviews, data encryption in transit and at rest, and least-privilege access control. For regulated industries we also support HIPAA, GDPR, and SOC 2 compliance workflows.
