Python & backend systems
The APIs, databases and automations behind your web or mobile app: built in FastAPI or Express on MongoDB or MySQL, with scraping and automation where you need it, and deployed on AWS with Docker, PM2 and Nginx.
What is it?
The backend is the part of a product that users never see: the API, the database and the jobs that run in the background, such as scraping, automation and reports.
Why use it?
One clean API lets your web app, mobile app, AI features and automations share the same data and rules, so nothing is built twice.
How I build it
- APIs in FastAPI (Python) or Express (Node.js and TypeScript).
- MongoDB or MySQL for storage.
- Scraping and browser automation with Selenium and Puppeteer.
- Deployed on AWS with Docker, PM2 and Nginx.
Why hire me?
I have built backends for web and mobile apps in FastAPI, Express and Spring Boot, and freelanced on Upwork since June 2016.
