A cloud-based editor, integrated into the Camunda platform, enables users to model, digitize, and transform their business processes using standards like BPMN, DMN, and RPA. Thousands of users utilize this application daily, be it with the free SaaS or extended on-premise version.

I worked with designers, product managers, and fellow developers to properly plan, scope, break down, implement, test, and ship new features and improve and refactor the existing codebase.

Providing code reviews, performing QAs, and receiving/giving mentoring sessions were also part of my role, making for a diverse work environment and load.

Vitra VCS
It is a modern replacement for an outdated extranet—it eases customer interactions and allows for more transparent and digestible documentation, provides essential resources, and serves as a first entry point for new clients.

This was the first actual project I built using Node.js and Express.js shortly after finishing my apprenticeship. After getting the green light from management, I planned, scoped, designed, implemented, and maintained the website independently.

Though I built this website in 2016, it remains mostly unchanged to this day and is used heavily by clients and the team.

Institute del Ambiente
A Jekyll-based website for a Dominican institute that I was working for. During my first year of being a volunteer, I took responsibility for designing, developing, and maintaining a completely new web experience for the institute to attract country-wide attention for funding and finding new students.

Simple Translator
An open-source JavaScript library that makes translations easy and painless.

Initially, I wrote a blog post on Medium about the topic and publishing the source code in the process. Once I noticed a growing interest from the community, I quickly expanded the scope and added new features, improved the API, and fixed bugs—making it a fully featured library available on NPM.

A React-based shopping list app that's optimized for mobile devices. This was a fun side-project, allowing me to dig into TypeScript and some concepts around it. The app is available for free online and can be used by anyone interested.

Leo-Club Weil am Rhein
This website was built for a local club of engaged, young volunteers who strive to do good for other people. As part of this club, I took care of crafting and maintaining a website to attract more public interest and to document our activities.

It is based on Gatsby, utilizing a custom theme powered by Markdown content. Hosting is done through Netlify's CDN for rapid loading performance. The source code is available on GitHub.
