FAQ
What kinds of web apps do you build?
Any kind. SaaS products, marketplaces, client portals, dashboards, admin panels and internal tools, with login, payments and a backend. Send me your idea and I'll suggest the right package.
What if you're late or the work isn't as agreed?
You get your money back. We agree on the scope and delivery date before I start. If I miss either, I refund you.
Can you add AI to my existing app?
Yes, if you want it. AI is optional. I can add a chatbot, AI agents, document search or OpenAI/Claude features to a new app or your existing React or Next.js app. For a bigger AI system, see my AI agents gig.
How can you deliver so fast?
I have 9+ years of experience and build with AI coding agents. I review every line myself.
Do you build mobile apps too?
Yes. React Native or native Swift and Kotlin apps for iOS and Android. See my mobile app gig, or message me.
Which tech stack do you use?
React and Next.js with TypeScript on the front end, and Node.js, Python or Go on the backend with PostgreSQL. I pick what fits your project, or work in the stack you already have.
Can you fix or update my existing web app?
Yes. Send me the repo or the link. I fix bugs, add features and improve React, Next.js, Node.js, Python or Go apps without rebuilding what works.
Can you build a full SaaS from scratch?
Yes. Login, teams, billing, admin and deployment. A first version takes 1-3 days and a full SaaS 15-21 days.
