Portfolio

2020 I was one of the author's for the paper Edge Matching with Inequalities, Triangles,Unknown Shape, and Two Players, in computational complexity.

2019 - My master's of engineering thesis in Boolean Satisfiability, supervised by Erik Demaine.

2019 -

A tool to scrape Brazilian Science Olympiad Websites for their news.

2018-2019 I organized the class 6.S092 twice while at MIT. It was an IAP class (1 month long in January), using CATSOOP to teach people the basics of algorithms.

2018- Org mode to blog exporter. Converts each header to a different file. This blog was written using it!

2018- Copy and paste HTML, Images or file lists into orgmode.

2018- Proof of concept that it is possible, in a reasonable time, to test the solvability of linear networks by calculating the Groebner basis of the linear network ideal.

It implements an algorithm described on An Algebraic Approach to Network Coding by Ralf Koetter, Member, IEEE, and Muriel Médard, Senior Member, IEEE.

2017- One of the photographers for the Yaoi on Fire performance of the MIT spinning arts club.

2017- For the class Intro to Making at MIT, my friends and I built an Electric Skateboard.

2017- An experimental text based game inspired by “the space under the window”, and by “A Dark Room”.

The user interacts with the text, and the text is written and rewritten based on the interaction with the user.

The game is unfinished, and theres is only about 1 minute of gameplay at the moment.

2017- Created ad campaigns for the Lazuli Motel website I previously created with a tight budget. For about $1 a day for 3 months, it brought approximately 80 extra visitor to the website per day. The average time spent per user on the website was 3 minutes.

It was not possible to analyze exactly how many clients the ad campaign brought to the business, but given how many times the business got contacted by phone during the ad campaign it seems that the campaign was fairly successful.

2017- I took HDR pictures from the rooms of Lazuli Motel in Botuca, SP, Brazil, and created a website for it, using Hugo as a static website generator.

The website was intended to be accessed on 3g networks, so the image quality and sizes were chosen in such a way to improve the user experience, and it is also a single page website in order to not reload already loaded information, and if the user's network fails, they can still continue to see the information that has already been loaded.

2016- A simple command line tool to download images from the imagenet dataset while storing them with humanreadable names and ignoring images that are too small.

2016- My friends and I built a 30x60 pixels led panel, using Ws2812b strips. I programmed the led panel graphics using Python, in a way that makes it easy to combine patterns and functions into new patterns.

2015- We built Cocoabot, a robot capable of finding cubes on a field and stacking them by color. Cocoabot had around 10.000 lines of C++11 code, split in 10 threads, running in an Intel Edison.

I was responsible for integrating the modules, writing the skeleton code for the threads, designing the state machine and the motor-controllers code, debugging the code with GDB and finding memory leaks. Documented on tinyurl.com/cocoabot.

2013- Designed and built an L-shaped wooden loft for me and my roommate during my first month at MIT. The loft was very stable and at one moment had over 6 people on top of it jumping and moving to confirm its stability.

2013- Undergraduate Researcher contribution to the paper "Seeing around corners with a mobile phone? Synthetic aperture audio imaging", in the Camera Culture group in the Media Lab.

2012- Study guide for the International Linguistics Olympiad, in pt-br. I wrote it as I was preparing to take part in IOL 2012 in Slovenia, in order the following Brazilian teams to prepare for IOL.

2012- Translation of the 2012 IPhO formula sheet from English to Portuguese, with minor edits to examples to make some concepts easier to understand.

2012- A text based game inspired by “the space under the window”, written in inform 7.

The user interacts with the text, and the text is written and rewritten based on the interaction with the user.

2019- The game was ported to javascript and now supports click instead of writing a_game_from_the_past.html

2012-2015. Youtube channel to spread information about Brazilian Science Olympiads. We interviewed participants of science competitions.

2012-2015 Besides organizing my own personal website about science competitions, I helped other 10 students create and spread their blogs about their science competition experiences. I dare say it was a huge success and many students commented on our blogs saying we provided inspirations to them to take part in science competitions.

2012- 2013. Personal blog with stories about the time when I took part in Science Olympiads. At its peak, it received 50 unique visitors per day and top posts had a few dozen comments. It was created as a way to debunk myths about science olympiads as well as their competitors, as well as a way to stimulate people to take part in science olympiads, specially those from smaller towns around Brazil.
I was originally from a small town and I didn't know how other people prepared for science competitions, since no one was taking part on them in my hometown. Through my blog I tried to provide a way to help people in similar situations.
Some of the readers of the blog were later selected to represent Brazil on IBO, IPhO and IOAA, which was awesome.
There was a problem with the wordpress database and the website went offline after a few years without being maintained; now we have a snapshot of how it was so others can still access it.

2009- now. First Brazilian website to help high school students and teachers to participate in Science Olympiads.
Used to have ∼500 visits per day.
Made with wordpress.org, migrated to jekyll in 2016 after a problem with the wordpress website. Dozens of volunteers have helped with the website, helping provide material, write news and find information about the competitions.

It was cited by the largest Brazilian newspaper in 2012, tinyurl.com/ocientificas.
