During my free time, I often do some experiments, try to bring some ideas to life or I do contribute to existing projects, sometimes on my own, sometimes together with other people. Not all of them see the light of the day, but every single one is important at least in the learning process and to improvement of my skills in different areas. Bellow you can find some examples of projects I previously worked on or am currently working on:

Own Projects


Using GPG is not an easy task for many non-tech savvy users. This leads to people often sharing credentials and secrets through insecure channels such as email and leaving it there is plain text. This tool helps you in situations where you want to receive securely certain information, you just generate a link, share it and anything submitted on that URL is automatically encrypted in the sender’s browser and forwarded to your email.




Small web-based tool that parses PGP public keys and displays several details about them. I built this tool because I regularly needed to inspecting different keys that were shared with me and didn’t want to load them into my “keyring” just to look one or two details.

More info can be found in this blog post.





This project intends to be a huge repository of short sounds (no more than a few seconds) to be used as reactions on on-line conversations or any other purpose where Gifsare used nowadays. Simply said it is something like Giphy but for sounds.

I’ve been part of the team since the beginning and we are still working on making it better and extending it through integrations.



Through my exploration of the Cryptocurrency and Blockchain world, I ended up working a bit with the NEO blockchain and developing some smart-contracts on that platform. For that purpose I used neo-pythonproject and while working with it I found some bugs. That was the beginning of my participation on the City of Zion community.


Small Experiments

Webhook Logger

This tool was developed as a small experiment for a blog post about working with websockets on a Django project. In the end it provided quick and useful functionality so I still keep it up to data. The source is available on Github.




Small DDNS system that makes use of Cloudflare’s Workers and API’s. The main idea was to use workers to overcome the lack of granularity of the permissions one can set for API tokens.

Bundlr’s Opera Extension

At the time when I was an Opera user, some web services that I used didn’t had an official extension to this browser, which led my to have screen space wasted in with bookmarks. Bundlr was one of them (now the service looks partially dead), so I built an extension the used the bookmarklet, that was later the foundation for the official one.

Note: This project is no longer available



This is a simple tool that helps you navigate and read groups of markdown files contained in a given folder on the browser, like you do on Github. This is specially useful for people that store lots of notes in markdown files.




This one wasn’t a specific need, but was born in order to test new technologies. In this case this project lets users create and share public “to-do lists”, that can be edited by several people in real-time, also having a discussion section for each element in the list. Later it was turned into a Firefox OS app as described here. It is no longer running but the code is publicly available.
