About this gig
Welcome to my custom ai saas web app, ai software development as a full stack developer gig.
I am a full stack developer who builds SaaS platforms and AI SaaS web apps from scratch architecture, MVP, and launch so you go from concept to a deployed, production-grade product. Not vibe-coded, not no-code real, scalable engineering.
What I build:
- Full stack web apps and Ai SaaS MVPs (Next.js / React frontend)
- Scalable backends and REST APIs with Python (FastAPI, Django) and Node
- AI integration: chatbots, OpenAI or Claude features, and automation
- Auth, user roles, dashboards, Stripe payments, third-party APIs
- PostgreSQL / MongoDB databases + cloud deployment on AWS, Azure, or GCP
Why Work With Me:
- 5+ years of shipping real production software
- Both JavaScript and Python, so your stack fits the problem
- I use Claude Code daily, so builds land faster and cost you less
- Clear updates, fixed scope, no surprise invoices
You get a deployed, working app, clean documented code, and full ownership built on scalable cloud infrastructure by an engineer who also does DevOps.
I define the exact screens and features up front, so scope, price, and timeline are clear before we start.
Thanks:

I'm an AI engineer, DevOps specialist and full-stack developer with over 5 years building software that runs in production. I design web apps and APIs, add AI where it actually helps (RAG, Claude, OpenAI), and handle the DevOps side: CI/CD, Docker, Kubernetes, and Terraform across AWS, Azure, and GCP.
I've worked on enterprise systems, integration work at a US AI SaaS, and automation across healthcare, pharma, and fintech. I care more about what's reliable than what's trendy, so I'll be honest about whether you actually need AI or just a simpler, cheaper solution that does the job.

FAQ
Can you build a full SaaS with payments and user roles?
Yes — that's the Premium package: auth, user roles, Stripe payments, an admin dashboard, and an AI feature, all deployed with docs.
What tech stack do you use?
Next.js and React on the front end; Python (FastAPI/Django) or Node on the back end; PostgreSQL or MongoDB for data. I'll pick the best fit for your project.
Will the app be deployed and live?
Standard and Premium include cloud deployment (AWS, Azure, or GCP). Basic can be deployed as an extra. You own all code and accounts.
Can you add AI features to my app?
Yes. I integrate chatbots, OpenAI or Claude features, RAG over your content, and automation. It's included in Premium or available as an extra.
Do I get the source code?
Yes. You get full, documented source code and a handover so you or your team can keep building on it.
Can you work on my existing app?
Often yes. Share your repo and stack and I'll assess it, then quote via the right package or a custom offer.
How do you handle unclear requirements?
Just message me your idea. I turn it into a defined list of screens and features, so scope, price, and timeline are clear before you order.
Who owns the final product?
You do — all code, repositories, and accounts are yours on delivery.
