You will get a AI SaaS MVP with Next.js, FastAPI & OpenAI
Project details
Most freelancers hand you a prototype. I hand you a product.
I specialize in building AI-powered SaaS applications that are fully production-ready, not just functional demos, but real software with clean architecture, scalable databases, secure authentication, and live deployments that can handle actual users from day one.
What sets this apart is the full-stack AI integration. I don't bolt on a basic ChatGPT API call and call it "AI." I architect proper AI layers using OpenAI, LangChain, or RAG pipelines that are actually connected to your data, your users, and your business logic.
Every project includes a scoping session before any code is written, so we align on architecture early and avoid costly rebuilds later. You get regular progress updates, a staging environment to review, a proper handover, a full GitHub repo, documentation, and a walkthrough call.
I've worked across SaaS tools, internal dashboards, and AI-driven platforms using Next.js, FastAPI, PostgreSQL, Stripe, and AWS/Vercel. Whether you're a founder validating an idea or a business ready to build seriously, this project gets you from zero to launched.
Clean code. Real AI. Built to scale.

I’m Arslan, a full-stack developer partnered with Devbox Technologies, with 8+ years of experience building AI systems, automation workflows, and scalable software products.
Most developers can set up a chatbot.
Most automation specialists can build a workflow.
Very few can do both and then build the actual software product around it.
That is what I do.
I am a full-stack developer and AI engineer with 8+ years of experience.
I build AI agents, chatbots, voice agents, and automation systems and when the job needs a custom web application or SaaS product behind it, I build that too.
One hire. Full delivery.
