About this gig

Looking for a small custom software tool, interactive simulation, automation tool or quality-of-life web app?


I'm a student developer from Switzerland focused on building small, polished and useful software products. I work with modern web technologies such as React, TypeScript, JavaScript and Python to create practical tools that solve real problems.


Examples of what I can build:


  • Interactive simulations and visualizers
  • Custom calculators and converters
  • Quality-of-life tools for repetitive tasks
  • File-processing or data-cleaning tools
  • Small dashboards and internal tools
  • AI-powered utilities and web apps
  • Educational tools and learning software


What you can expect:


  • Clean and modern interface
  • Responsive design for desktop and mobile
  • Well-structured code
  • Clear communication
  • Honest scope estimation
  • Focus on usability and product quality


This gig is best for small to medium-sized tools, prototypes, dashboards, simulations and focused software products.

Hi, I'm Janis, a student developer from Switzerland. I build polished software products and AI-powered tools for learning, simulations, file conversion, dashboards, websites and small automation systems. I focus on turning complex ideas and repetitive workflows into clear, useful and well-designed web applications. I'm early in my journey, but I care deeply about quality and only take on projects where I can deliver something I can stand behind. Beyond client work I explore machine learning, brain-inspired AI and robotics, which helps me stay curious and push my skills forward.
