Frequently Asked Questions

How quickly can we start?

I am available to start within 48 hours after we finalize the agreement. Since I operate under a US-based LLC with C2C or UK Outside of IR35 contracts ready, there are no delays in legal paperwork or compliance. Just book a quick call, and we can outline the scope of work, sign the contract, and begin development almost immediately.

How do payments work?

I accept payments via ACH, Wise, and Stripe, ensuring secure and traceable transactions. All payments are processed through my US-based/UK-Based Bank business account, eliminating any concerns about international transfers. I work with Net 15 or Net 30 payment terms, depending on the contract, so your finance team can handle invoicing smoothly.

What happens if we need to scale up development?

I offer flexible C2C contracts that allow startups to scale engagement as needed. Whether you require 20, 30, or 40+ hours per week, I can adjust my availability to match your project’s growth. Additionally, I work with efficient development workflows, meaning you can onboard me quickly and get immediate results without any delays.

Can we start with a test project?

Yes! I offer a risk-free 20-hour paid trial, allowing you to assess my skills, speed, and communication before committing to a long-term engagement. This way, you can see firsthand how I integrate with your team, deliver high-quality code, and contribute to your startup’s success—without any long-term obligation. If you’re satisfied, we can move forward with a standard contract for ongoing collaboration.

Are you legally allowed to work with US companies?

Yes, I operate as a fully registered US LLC with an EIN and IRS compliance, making it easy for any US company to contract my services. Unlike offshore freelancers, I provide a legally binding C2C contract, ensuring compliance with US/UK business regulations. This means no W-2 requirements, no employment risks, and no tax complications for your company.

Why should we choose you instead of an agency or offshore developer?

Unlike agencies, I offer direct, one-on-one collaboration without middlemen, delays, or inflated costs. Compared to offshore developers, I provide real-time availability in US/UK time zones, clear communication, and a legally secure business structure—all at a competitive rate without sacrificing quality. With 17+ years of experience, I specialize in building scalable applications, optimizing APIs, and helping startups create investor-ready technology.
