FAQ
Why should you choose me?
I offer 10+ years of exp and 50+ successful SaaS projects. Unlike others who build basic prototypes, I architect for long-term scalability, security, and high performance. I build business tools that handle thousands of users from day one.
What’s included?
Depending on the package, I provide full-cycle development: UI/UX implementation, frontend (React/Next.js), backend (Node.js/NestJS), database architecture, API integrations, and secure authentication. Every project includes clean, documented code and a deployment-ready environment.
What’s not included?
My focus is on technical execution and architecture. Therefore, legal compliance (GDPR/Terms of Service), content writing, and paid marketing/SEO services are not included. Also, third-party subscription fees (AWS, Stripe, Domain) are the responsibility of the client.
Which tech stack do you recommend for a new SaaS?
For most modern SaaS products, I recommend Next.js (React) for the frontend and Node.js with PostgreSQL or Supabase for the backend. This stack offers the best balance of development speed, SEO performance, and high scalability.
Can you help me migrate my existing platform to a new stack?
Yes. I have extensive experience in refactoring and migration. I can help you move from legacy systems to a modern stack (like Next.js/Node.js) without losing data or disrupting your current users.
How do you handle SaaS security and data protection?
Security is my top priority. I implement JWT/OAuth 2.0 for authentication, role-based access control (RBAC), data encryption, and protection against common vulnerabilities like SQL injection and XSS. Your users' data will be handled according to industry standards.
Do you provide support and maintenance after the launch?
Absolutely. I offer a 30-day post-launch support period to fix any bugs or technical issues. For long-term maintenance and new feature updates, we can discuss a monthly retainer or milestone-based updates.
Can you integrate AI or machine learning features into my SaaS?
Yes. I can integrate OpenAI (ChatGPT), Anthropic, or custom AI models via APIs to add intelligent features like automated content generation, data analysis, or chatbots to your platform.
Is the code you write "mine" after the project is finished?
Yes, 100%. Once the project is completed and the payment is released, you own full intellectual property rights to the source code. I will provide you with the GitHub repository and all necessary documentation.
How do we start? What do you need from me?
The best way to start is to message me first. I’ll need your project requirements, wireframes (if any), and a list of core features. We will have a quick discovery call or chat to align on the goals before I start the development.
