Hello beings of the universe, 🖖

My name is Mariana Meireles[she/her]. Welcome to my professional website with sprinkles of personal me.

I'm a software engineer @Anaconda, a subject matter expert on the "Ethos of open science" @NASA and an activist for ethical open source, animal liberation, leveraging democracy through open democracy practices, combating disinformation in the Web and empowering people to overcome poverty using education, land redistribution coupled with permaculture and local integration techniques and offering OSS opportunities through internships and mentoring.

I'm doing lots of Python, Javascript and WASM lately and I'm very excited about the impact we can make on education and the democratization of software through the PyScript project. I have an non exhaustive list of tech pet projects. I'm also thinking and researching a lot about OSS and FOSS: the history, the different organizations that emerged out of these social structures and their social implications. Some of this work is under NASA (and will be released to the public later on 2022) but sometimes I add some notes in this document too.

I'm a Jupyter distinguished contributor and a member of the Jupyter Widgets steering council, where I sometimes help with outreach, code and general decision making. I'm also part of the NumFOCUS DISC committee where I'm trying to implement an open source internship program similar to Outreachy but mostly focused on the Global South.

I'm driven by meaning and I find a lot of significance and love in open/libre software and the internet and I love to work with it. The concept of liberating knowledge and nurturing cultural and scientific development deeply resonates with many of my personal goals and working towards making the digital world more accessible and comfortable for all is a very fulfilling mission to me. I'm recently also very interested in forms of governance and organization and how we can use these theories to leverage people out of poverty. Currently trying to combine these two passions. 🙂

If you're interested in talking to me about any of the things you spot here in this website, please feel free to reach out, check the Community session or schedule a call with me.

If you're a recruiter looking to get in touch with me please check the requisites and have a sit in the waiting room. I'll come talk to you as soon as I can.

Feel free to look around!

I'm in these places, but really, just send me an email or better yet, let's meet IRL!

I'm available for an asynchronous chat here mariana@psychonautgirl.space and for a synchronous one here.


I found out the way I learn the best is by having the support of a community. Do you want to learn something together? Just shoot me a message with your availability and what you'd like to tackle together.

Social injustice fighting

How can you make a difference?


For absurd legal reasons, doctors in Germany are not allowed to post factual information on abortions on their websites. Other websites are allowed to post this information, though. Frag Den Staat is currently providing resources on the subject in German, English and Turkish.

Be excellent to each other.
