Sobre este Serviço

Need a web app built around your workflow? I can develop a React interface and a Python FastAPI backend for dashboards, internal tools and focused MVP features.


We start by defining the screens, data and user actions your app needs. You receive source code and setup instructions, with the features and testing agreed before development.


Depending on the package, the scope can include:

- Responsive React screens

- FastAPI endpoints and database integration

- Form validation and error handling

- A documented handover


Each package covers a clearly defined feature set. Hosting, paid APIs, third-party subscriptions, complex payment flows and ongoing maintenance are quoted separately. Authentication is included only when explicitly scoped.


Send me your brief, sketches or existing repository before ordering so I can confirm the right scope and delivery time.

I help turn technical ideas into working software and prototypes. I lead ONIT, a small engineering studio covering React and FastAPI web apps, Arduino and ESP32 firmware, Siemens PLC programming, and Fusion 360 CAD. Our workshop includes 3D printing, CNC and electronics equipment, so hardware validation can be planned when suitable equipment is available. Tell me what you want to build, your current setup and your deadline. We will define the deliverables, testing approach and scope before work begins.
