FAQ
Why should I message you before ordering?
Backend requirements vary widely. Messaging first helps me understand your product, recommend the right architecture, and ensure the best outcome with no surprises.
What type of backend work do you handle?
I build and maintain scalable backends for SaaS products and web apps, including APIs, databases, authentication systems, payments, and third-party integrations.
Which backend technologies do you use?
I work with Node.js, Express, NestJS, JavaScript/TypeScript, PostgreSQL, MongoDB, MySQL, Supabase, Firebase, REST APIs, GraphQL, and Redis.
Can you work on an existing or live system?
Yes. I frequently audit, fix, refactor, and scale backends that are already in production, including performance and security improvements.
Do you handle authentication and security?
Absolutely. I implement secure authentication, role-based access control, API protection, and best practices to keep your data and users safe.
Can you integrate payments and third-party services?
Yes. I’ve worked with Stripe, webhooks, and many third-party APIs for payments, notifications, analytics, and automation.
Will the backend be scalable and future-proof?
Yes. I design clean architecture from day one so your backend can handle growth without costly rewrites later.
Do you provide documentation and support?
Yes. I deliver clean code, clear documentation, and optional post-delivery support if needed.
How do we get started?
Send me a message describing what you’re building or fixing. I’ll review it and suggest the right backend approach before we begin.
