Aleksandra Weber, software engineer
Backend and system architecture: from data model to deployment.

What you get in practice
Backend & system architecture
I design and build the server side of your product: from the data model and API to deployment and maintenance.
- System architecture and data model
- Databases: schema design and migrations
- APIs and endpoints (REST) with documentation
- Authentication, permissions and security
- Integrations: payments, email, third-party APIs, AI
- Deployment: Docker, CI/CD, cloud
Python (FastAPI, Flask) · PHP (Laravel) · Node.js · PostgreSQL · Docker
Mobile & web apps
When you need the whole product, I build the app your users work with on top of the backend.
- Flutter: iOS, Android and web from one codebase
- React and Next.js
- Sign-in, payments and subscriptions
- Release to the App Store and Google Play
I also do
Devices & IoT
Device integrations over Bluetooth Low Energy: reading, sending and presenting data.
AI in products
Language models and automation where they save time for your users or your team.
Website security
Security reviews of websites and web apps, with a report on what to fix.

Book a free 20-min callHow we work
From the first call to a working product in five steps.
Call (20 min, free)
You tell me about the idea and the goal. We check whether and how I can help. No strings attached.
Quote and plan
You get the scope, a timeline and a quote, so you know exactly what we're agreeing on.
Sprints with weekly demos
Every week you see a working version and can give feedback right away.
Launch and release
I deploy the system to the server and publish mobile apps on the App Store and Google Play.
Support and growth
After launch I help maintain the product and keep developing it.
Who I am
I'm a software engineer running a one-person studio. You talk directly to the person who writes the code, with no middlemen.
I specialise in backend and system architecture, and I also build mobile and web apps, so you don't need three people for one project. I know the whole system and I'm responsible for it working as a whole.
Every week you see a working demo, not a progress report. The code and infrastructure access stay yours.
