Common Questions
How do you handle project visibility and communication?
You get a dedicated project Slack channel, weekly video calls, daily asynchronous updates, and full access to the project management board. We assign a dedicated project manager as your single point of contact for all communications.
How do you handle security and data protection?
We build with security best practices from day one: encryption, access control, audit logging, regular backups and data-residency choices. We do not hold formal certifications such as SOC 2 or ISO 27001; if your project needs one, we design to support your own compliance process.
Can you take over an existing codebase?
Yes. We perform a code audit first (1–2 weeks), documenting technical debt, security issues, and architecture problems. We then propose a refactoring roadmap with prioritized improvements and can begin parallel feature development while improving the existing codebase.
What is your development methodology?
We follow Agile/Scrum with 2-week sprints. Each sprint produces working, tested software. You participate in sprint planning, attend demos, and can reprioritize the backlog at any sprint boundary. We use GitHub for code, Linear for project management, and Notion for documentation.
Do you offer ongoing maintenance contracts?
Yes. We offer Engineering-as-a-Service (EaaS) retainer packages ranging from 20 to 160 hours per month. Retainer clients get prioritized response times, dedicated engineering capacity, and proactive monitoring and security patching.
