About Me

I love to innovate, research, brainstorm, architect, prototype, create, and develop awesome things. I'm very curious, and easily intrigued by hard problems and new challenges.

I'm a creative entrepreneur with a solid background in technology; a computer scientist with a broad and strong set of skills, which includes problem solving, product development, product vision, data science/analytics and software architecture. For fun, I design, create, and hack hardware and software projects. I also enjoy playing guitar and drums, writing about tech, storytelling, creating artwork, songwriting, and collecting certain vintage computers.

My first computers were a TK90X (a Sinclair Spectrum Clone) and a Hotbit MSX. I first learned about computing by reading a lot of books and magazines, and by accessing every Bulletin Board Systems (BBS) whose dial-in numbers I could get my hands on. I am pretty sure I was one of the first kids in Brazil to have a modem (with a speed of 300bps) back in 1987.

Work

OnlyBoth Inc.

CTO February 2014 - Present

OnlyBoth analyzes data sets by looking for novel comparative insights and then reporting all findings in English, just as if a human had done the research and written the reports. Its technology combines machine discovery – Artificial Intelligence algorithms that discover humanly-digestible knowledge – with natural language generation (NLG), making insights easy to read and share in perfect English. At OnlyBoth, I designed and created the web application and manage all the AWS infrastructure and web development.

Meaningfy Inc.

Founder February 2012 - February 2014

Meaningfy was a web service that allowed users to track news related to specific companies, products, and industries of interest (think "Google Alerts" on steroids). It was a competitive intelligence web service based on Machine Learning recommendations and user collaboration. It provided teams with an up-to-date, consolidated view of their competitive landscape. The company was accepted into 2 startup accelerators (AlphaLab/IW and IdeaFoundry), raising $50K between them. In addition, it also received a bit of funding from CMU's i6 Agile Innovation System.

Client Testimonials

  • Imagination’s greatest threat is the absence of an inspired and organized mind.

    André Lessa
  • If you don't question why things are what they seem to be, they will just keep being what they've always been. And if you don't question why things only do what they are known to do, then they will never do anything different apart from what they've always done.

    André Lessa
  • Things are only impossible until they're not

  • I have a new theory: Andre's brain does not function like everybody else's. In front of a wall, Andre does not see a wall, he sees an infinite number of cracks, pathways to the other side of the wall.
