Work experience

2014 - 2017: Agile Developer and Software consultant at XPeppers
2017 - 2020: Full Stack Developer at Wonderflow
2021 - now: Working as a Software Developer at Casavo

Between 2014 and 2017 in XPeppers I adopted essential agile & eXtreme Programming practices. Learned to write maintainable software, collaborate with my team and ship valuable product increments to the customer.

From 2017 until mid 2020 I worked at Wonderflow, a company based in Amsterdam/Trento, in the customer feedback field providing market-research analysis to businesses. One of the first hires, contributed to creating a solid development team and mentored others.

Currently employed at Casavo, improving the housing experience, one digital step at a time. I'm diving deep into Domain-Driven Design, Event-Sourcing, mainly Elixir and JS, Kotlin and Python.

Collaborations

2021: Worked on The Lean Validation Playbook together with Fightbean and Matteo Cavucci

“Polyglot Fullstacker”

I really like the web, from the UI to the backend.

My main programming languages are JavaScript and Elixir.

Have solid experience with the Node.js runtime, and I am quite productive with vanilla-JS and various libraries and frameworks on the client-side.

Worked on Phoenix backends, built event-driven software systems leveraging the BEAM with Elixir.

I also get things done in Kotlin and Python.

Had the opportunity to work with Java, Ruby (on Rails) and PHP too.

It was also very refreshing and I learned a ton when I experimented with Haskell (FP101 MOOC of Uni Delft), Elm and Go.

Tests, refactoring, clean code? That’s my jam.
docker, nginx, haproxy, continuous integration & deployment? If you like these, I respect you
If I say “JavaScript” and you don’t run away, there’s a high chance we could get along well.

Open-Source Projects

Open-source has been a part of me since the very beginning.

My OSS can be found on my GitHub profile.

Coding in all kinds of tech fields that bring value to me, read IoT, Crypto, Bots, Apps, CLI utilities, Automation of all kinds.

mega-scraper aims to be a simple website scraping tool with proxy support, request blocking and various optimizations.

In April 2020 I made a fast static site generator and called it devblog

At the beginning of 2021 I was very interested in web analytics and self-hosting.
That’s where Minimal analytics was born.

In the field of IoT, I made a watering system with a raspberry pi, camera, temperature and moisture sensors. the communication was handled via telegram and interactive buttons.
With the help of a bot I can water, request a snapshot or video of the garden and a timelapse of the past days.
Most importantly this enables me to water my plants remotely and seeing their current state through an image sent on a private telegram channel.

That was a fun time.

Right now I am probably writing code for
