Need a real web app, not another spreadsheet and e-mail chain?

I build complete web apps in Python: a fast FastAPI backend, a PostgreSQL database and a clean, responsive web interface your team can use from day one. Secure sign-in, roles and automated tests come built in.

This is for you if • You want an MVP to test your idea with real users • Your team runs a process on spreadsheets and e-mail and needs a proper internal tool • You need an admin panel or a dashboard over your own data • You have an API and need a web interface on top of it, or the other way round

What you receive • A FastAPI backend: REST API, input validation, clear error messages and interactive API docs • A PostgreSQL database with migrations, so future changes are safe to roll out • A clean, responsive web interface (pages, forms, tables and dashboards) built with HTML, CSS and JavaScript • Secure sign-in: hashed passwords, short-lived tokens, and roles and permissions for your team • Automated tests, a Docker setup that runs the same everywhere, and a setup guide • The full source code, yours to keep

Options you can add • Accounts and security: two-factor sign-in, passkeys, single sign-on (OIDC) and an audit log • Teams: organisations, roles, permissions and invitations • Data: CSV and Excel import and export, file uploads and search • Integrations: Stripe payments, e-mail notifications and third-party APIs • Background jobs: scheduled tasks, generated reports and alerts • AI features: a chat assistant or document Q&A with OpenAI or Claude • Deployment: Docker on your server or cloud, behind HTTPS

You describe what the app should do, who will use it and which pages you need.

I send a written plan: pages, data model, roles, and what's in and out. Nothing starts until you approve it.

I build in small steps and share a working preview as I go.

You test it with your real use cases and I fix what you find.

You receive the code, the guide and a walkthrough, and I help you deploy it.

Proof you can check NexusFlow, my open-source business automation platform: FastAPI, PostgreSQL with row-level security, a framework-free web console under a strict security policy, passkeys, two-factor and single sign-on, five roles and 38 permissions, with 2,561 automated tests at 90% coverage. https://github.com/mojtaba-py-code/fastapi-postgres-ai-automation-platform

AI Document Assistant, a web app where teams upload and search their documents: FastAPI, PostgreSQL with pgvector, a single-page web interface for non-technical users and five roles, with 1,746 automated tests. https://github.com/mojtaba-py-code/ai-document-assistant

Not included React, Vue or Django front ends (I build with FastAPI and plain HTML, CSS and JavaScript), native mobile apps, logo or brand design, and hosting or domain fees (paid directly by you).
