Common Questions
Frequently Asked Questions
Answers to common questions US companies ask when considering offshore React development.
How does timezone overlap work with your India-based team?
Our React engineers adjust their schedules to provide 4-6 hours of daily overlap with both EST (9 AM - 1 PM EST) and PST (6 AM - 2 PM PST). We start our workday at 6:30 PM IST to align with your morning/mid-day. This enables real-time communication via Slack, daily standups during your business hours, live code reviews, and instant responses to urgent issues. For non-overlapping hours, we work asynchronously with detailed PR descriptions, Loom videos, and comprehensive end-of-day summaries so you wake up to progress, not blockers.
How much can we save compared to hiring US-based React developers?
US companies typically save 40-60% compared to domestic hiring costs. A senior React engineer in San Francisco or New York costs $120K-$180K annually (plus benefits, equity, office space). With Cloudzies, you access the same caliber of talent—5-10 years of experience, strong English communication, expertise in Next.js, TypeScript, and modern React patterns—at $50K-$80K per year. For a team of 4 React engineers, you're saving $200K-$400K annually while maintaining enterprise-grade quality, security compliance, and transparent communication.
How do you protect our intellectual property?
We provide US-enforceable NDAs drafted by legal counsel familiar with US intellectual property law. All code, designs, and documentation created by our team transfer to you immediately upon creation—100% ownership from day one. We use secure development environments with VPN access, encrypted communication channels, and strict access controls. For enterprise clients, we maintain SOC 2 Type II awareness and can work within your security infrastructure (SSO, 2FA, audit logs). Our contracts include non-compete and IP assignment clauses ensuring your product remains exclusively yours.
Can your developers join our existing US team's workflow?
Absolutely. Our React engineers integrate seamlessly into US development teams. We use your preferred tools—Jira, Linear, Asana for project management; GitHub, GitLab, or Bitbucket for code collaboration; Slack or Microsoft Teams for communication; Figma for design handoff. Your developers attend your daily standups, participate in sprint planning and retrospectives, follow your coding standards and Git workflows, and receive tasks through your existing ticketing system. You manage our team just like in-house employees—the only difference is location and cost.
What communication tools do you use?
We adapt to your existing communication stack. For real-time messaging, we use Slack, Microsoft Teams, or Discord. For video calls, we're proficient with Zoom, Google Meet, or Microsoft Teams. For async updates, we provide Loom screen recordings, detailed Slack summaries, and comprehensive PR descriptions on GitHub/GitLab. Our engineers have high-speed fiber internet (100+ Mbps) ensuring smooth video calls and screen sharing. We maintain professional English communication—both written and spoken—with clear documentation, structured updates, and proactive status reports.
Do you work with US startups or only enterprises?
We work with both. 60% of our US clients are startups (pre-seed to Series B), including companies backed by Y Combinator, Techstars, Sequoia, and Accel. We understand the urgency, resource constraints, and pivot-friendly approach startups require. We've delivered MVPs in 6-8 weeks for pre-seed companies, scaled post-funding teams from 2 to 10 engineers, and supported Series A startups through rapid growth. For enterprises, we provide SOC 2 compliance, multi-team coordination, legacy modernization, and formal change management processes. Whether you're a 3-person startup or a 1000-person company, we tailor our process to your maturity level.
