01 / Services

Your plans.
The right solution.

Want to be found, simplify your workflows or bring a new idea to life? Together we work out what you really need.

01

Websites

A clear presence that shows who you are and what you offer – so visitors find their way around and can get in touch easily.

  • Company websites & landing pages
  • Made for phone, tablet & desktop
  • Structure, design & build

For your first impression.

02

Web apps

Fewer lists, detours and manual work. An application in the browser that simplifies your workflows and brings the right information together.

  • Client portals & internal tools
  • Dashboards & digital workflows
  • Integration with existing systems

For your everyday work.

03

Custom software

Some ideas don't fit any off-the-shelf solution. I build the features your business needs – from scratch or as an extension of your software.

  • Solutions built to your requirements
  • Interfaces & extensions
  • Maintenance & further development

For your next steps.

02 / About

Hi, I'm
Wellington.

The person behind Santos Systems.
And behind your next project.

I'm a software engineer building websites and software for businesses in Switzerland. What drives me is how a good idea turns into a solution that genuinely helps day to day.

With me, you talk directly to the person building your project. I listen, explain technical questions in plain language and keep you up to date on progress.

Personal in conversation.
Careful in execution.

03 / Working together

From “I have an idea”
to “It works”.

A clear process, short lines of communication and one fixed contact. That's how your project comes together.

  1. Step 1:

    Getting to know

    We talk about your idea, your business and what matters to you.

  2. Step 2:

    Concept

    I make a concrete proposal covering structure, features, effort and approach.

  3. Step 3:

    Build

    I develop your solution. You see progress along the way and can give feedback at any time.

  4. Step 4:

    Handover

    We test together, go live and I show you how to use your solution.

After launch, I'm still there for questions, maintenance and further development.
