Summary
FAQs
How do you ensure the security of financial transactions?
Security is my priority. I implement enterprise-grade standards including JWT for authentication, Role-Based Access Control (RBAC), and end-to-end data encryption. I also ensure all payment integrations (Stripe, Paystack) follow PCI-DSS best practices, ensuring sensitive data never touches our servers directly.
Will the platform be scalable if we grow quickly?
Yes. I architect systems using Node.js and NestJS, which are designed for high concurrency. This is the same architecture I used for Vendyz, which successfully scaled to over 6,000 active users and millions in transaction volume without performance degradation.
Is the Landing Page and Platform SEO-friendly?
Absolutely. I build the frontend using Next.js, which utilizes Server-Side Rendering (SSR). This ensures that Google and other search engines can crawl and index your content immediately—a significant advantage over standard React apps.
Do you provide support after the project is launched
Yes, I offer a standard 2-week hypercare period post-launch to fix any immediate bugs. For ongoing maintenance or feature updates, we can discuss a separate retainer agreement to ensure your platform runs smoothly.
Do I need to have the design ready?
Ideally, yes. I specialize in translating high-fidelity designs (Figma/Adobe XD) into pixel-perfect code. However, if you don't have a designer, I can build a clean, modern interface using professional UI systems like Tailwind UI to get you to market fast.
