FAQ
Should I message you before placing an order?
Yes, always. Messaging first allows me to understand your architecture, goals, and constraints, and propose the best technical solution for your project.
Is long-term support available after delivery?
Yes. I offer ongoing maintenance, scaling support, and feature expansion, especially for startups and SaaS products that evolve over time.
Do you handle backend architecture for mobile apps as well?
Yes. I design and build scalable backend systems and REST APIs for mobile applications, ensuring secure authentication, performance optimization, and clean API contracts.
Can you help with system architecture and technical design?
Yes. I actively help with system architecture, database design, API structure, and scalability planning. This includes deciding monolith vs micro-services, data flow, authentication strategies, and cloud-ready architecture.
Can you build MVPs that can scale later into a SaaS product?
Absolutely. I design MVPs with future scalability in mind, so your product can grow without costly rewrites. This includes clean separation of concerns, modular APIs, and database schemas that support growth.
Can you improve or refactor an existing system?
Yes. I can review, refactor, and redesign existing systems to improve performance, security, and maintainability. This includes restructuring APIs, optimizing databases, and improving overall architecture.
How involved are you in technical decision-making?
Very involved. I work as a technical partner, helping you make informed decisions around architecture, performance, cost, and long-term growth—not just writing code.
Do you help with deployment and cloud setup?
Yes. I handle production deployment using AWS, Docker, and CI/CD pipelines, ensuring your system is secure, scalable, and ready for real users.
Do you only work with MERN stack projects?
No. I work with Node.js–based architectures, including MERN, PERN, NestJS, Express, and custom stacks. I choose technologies based on your product needs, scalability goals, and long-term maintainability—not limitations.
