Frequently Asked Questions

Everything you need to know about working with us on your system development project.

Project timelines depend on system complexity. Simple websites: 2-4 weeks. Business systems with custom backend: 4-12 weeks. Enterprise platforms with infrastructure setup: 12-24 weeks. Every timeline includes design, development, infrastructure setup, testing, and deployment.

We offer flexible pricing based on project needs: fixed-price for well-defined scopes, time & materials for evolving projects, or dedicated pod retainers for ongoing partnerships. Contact us for a custom quote tailored to your project.

We handle everything end-to-end, but integrate with your internal team when needed. We use your preferred tools (Slack, Notion, Jira, etc.), provide a dedicated project manager, run regular standups, and give you access to real-time progress updates. Think of us as an extension of your in-house team — from design through to infrastructure.

We're stack-agnostic but specialize in React, Next.js, Node.js, and modern frameworks. For design, we work primarily in Figma. We also handle databases (PostgreSQL, MongoDB), headless CMS (Sanity, Contentful), server infrastructure (Nginx, Linux, Docker), CI/CD pipelines, and cloud deployment (AWS, Vercel).

Absolutely. Every system we build comes with a 30-day warranty period for bug fixes. We also offer ongoing infrastructure monitoring, server maintenance, feature development retainers, and performance optimization to ensure your system stays healthy and evolves with your business.
