My Portfolio
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?
Full-cycle development: UI/UX implementation, Frontend (Next.js), Backend (Node.js), DB architecture, API integrations, and secure Auth. You get clean, documented code and a deployment-ready environment on AWS/Vercel.
Do you provide post-launch support?
Yes, I offer a 30-day support period to fix any technical issues. For long-term maintenance or new features, we can discuss a monthly retainer or milestone-based updates.
What’s NOT included?
Legal compliance (GDPR), content writing, and marketing/SEO services are not included. Third-party fees (AWS, Stripe, Domain) are the client's responsibility. My focus is strictly on technical execution and architecture.
Which tech stack do you recommend?
I recommend Next.js (React) for frontend and Node.js with PostgreSQL/Supabase for backend. This stack provides the best balance of speed, SEO, and high scalability for modern SaaS platforms.
Can you migrate my existing platform?
Yes. I have extensive experience in refactoring and migration. I can move your legacy system to a modern stack (Next.js/Node.js) without data loss or disrupting your current user base.
How do you handle security?
I implement JWT/OAuth 2.0, role-based access control (RBAC), and data encryption. I protect your SaaS against SQL injection and XSS vulnerabilities, ensuring your users' data is handled by industry standards.
Can you integrate AI features?
Absolutely. I can integrate OpenAI (ChatGPT), Anthropic, or custom AI models via APIs to add features like automated content generation, data analysis, or intelligent chatbots.
Will I own the source code?
Yes, 100% ownership. Once the project is completed, you own all intellectual property rights. I will provide the GitHub repository and all necessary technical documentation.
How do we start?
Message me first. I’ll need your requirements, features list, and wireframes (if any). We’ll have a quick chat to align on goals and tech details before I start development.
