Project details

You will get a real, working web app — not a prototype that dies on your laptop.

I build on Google Firebase: Firestore for the database, Firebase Authentication for login, Cloud Functions for server-side logic, and Firebase Hosting, so your app is live on the internet the day it's delivered.

Everything is created inside your own Google account. You own the project, the data and the source code from day one — no lock-in, and any Firebase developer can pick it up later.

One thing most cheap Firebase apps get wrong: they ship with open database rules, which means anyone who finds the endpoint can read or overwrite your data. Every package here includes written Firestore security rules, tested against real read and write attempts before delivery.

I've shipped production apps that businesses use daily — a booking and quoting platform for a safari operator, a financial analysis tool, and a member portal for a sports club.

About Marco

Marco M.Status: Offline
Full-Stack & AI Engineer | React, TypeScript, LLM, Google Cloud
Milan, Italy - 8:18 pm local time
I'm a full-stack developer specialized in AI-powered applications. I build web apps, booking engines, custom CMS platforms and AI solutions (LLM integrations, RAG pipelines, intelligent automation) with React, TypeScript, Firebase and Google Cloud.

I work across the whole stack: React frontends, Node.js or Python backends, everything deployed on GCP.

I don't overcomplicate things.
APIs should be reliable and straightforward.
Interfaces should be fast and easy to use.
AI should solve real problems, not be a gimmick.
Infrastructure should scale without becoming a nightmare to maintain or a money pit to run.

Over the years I've built booking systems, document analysis pipelines with LLMs, data aggregation platforms and automation tools so I'm used to adapting to different domains quickly.

If you have something running and need it improved, want to add AI capabilities to an existing product, or you're starting from scratch, I can help you move forward without adding unnecessary complexity.
