FAQ
Can you build a complete SaaS or web application?
No. I work with React and Next.js on the frontend, Node.js, Express, NestJS, Python, Django and FastAPI on the backend, and PostgreSQL, MySQL or MongoDB depending on the project.
Can you work on my existing application?
Yes. I can add features, fix bugs, improve performance, refactor code, build APIs, integrate third-party services and continue development on existing applications.
Can you build an MVP for my startup?
Yes. I can help define and build the core functionality needed for a usable MVP. Please message me before ordering because MVP scope varies significantly between projects.
Can you add AI features to my application?
Yes. I can integrate OpenAI, Claude, Gemini, LLM assistants, RAG, document-based AI workflows and other AI-powered features depending on the product requirements.
Can you integrate Stripe or other APIs?
Yes. I work with Stripe, payment systems, REST APIs and third-party services. Complex integrations are scoped separately based on the API and required workflow.
Can you deploy my application?
Yes. I can assist with Docker, VPS servers, Nginx, PM2, AWS, Vercel and other common production environments. Deployment scope depends on your infrastructure.
Which package should I order?
Basic is for one small task, Standard is for a functional full stack module, and Premium is for a larger SaaS/MVP starting scope. Please message me first if you are unsure.
Do I receive the source code?
Yes. Source code for the completed development work is included unless we agree on a different arrangement before starting.
Can you work with me long term?
Yes. I can support ongoing product development, maintenance, new features and technical improvements through custom offers or milestone-based projects.

Ijaz really impressed me with his knowledge. A developer had been working on my site for six month with poor results. Ijaz came in and fixed the malfunctions that was occurring. If you are looking for someone knowledgeable with React JS, Ijaz is the guy for the job!
