FAQ
Do you work alone or as part of an agency?
I work strictly as an independent solo developer. This ensures you communicate directly with the person writing your code, resulting in zero miscommunications, faster delivery, and a dedicated focus on your MERN stack project.
Can you really fix my Node.js or React bug in 24 hours?
Yes! My Basic package is specifically designed for emergency troubleshooting. If you provide clear error logs and source code access, I prioritize your task to get your application running smoothly within a day
Will the code be scalable and easy to maintain?
Absolutely. I prioritize "clean-code" architecture. I write modular, well-commented, and scalable React and Node.js code so your application can easily grow and be maintained in the future.
Can you integrate complex APIs and payment processors?
Yes, I have extensive experience securely integrating third-party APIs, payment processors, CRMs, and custom webhooks into custom MERN applications.
How do we start a custom web application project?
Send me a message with your project requirements or designs. We will discuss the architecture, database schema (MongoDB), and timeline before starting to ensure we are 100% aligned.
