My professional journey is built on solving real-world problems with practical, creative solutions. I've led teams in unfamiliar fields—from preparing robotics teams for competitive tournaments to coordinating projects for the National Confederation of Industry (CNI) in Denver, Colorado, and even achieving international recognition in robotics. More recently, I stepped in as CEO of a startup focused on quantitative research and investment strategy. Over the past 15 years, I have managed diverse projects and teams, always delivering tangible results. I believe that my hands-on experience in problem-solving and project management can directly contribute to improving your business.

CEO on QuantSe - Research from a quantitative finance perspective
Jun 2020 - Present - 4 years 8 months and counting
Brazil · Remote
Languages: Python, JavaScript (the bare minimum to front-end work)
Skills and Tools:
Over the last five years as CEO of this startup, I've been involved in every stage of its life cycle - from the initial challenges, often referred to as the ‘death valley’, to winning the first major clients that have consolidated the sustainability of the business. During this period, I worked side by side with professionals of high technical competence and diverse profiles, which naturally led to moments of impasse and debate about the best way forward. I was responsible for managing tax details, coordinating the projects developed and making strategic decisions in situations where the partners disagreed. Currently, the startup has had two consecutive years (23/24) of positive results and continues to grow.
Fintech
Set 2018 - Jul 2020 - 1 years and 11 months
Brasilia, Distrito Federal, Brazil · in office position
Languages: Python, VisualBasic
Skills and Tools:
In 2018, I was invited to manage a financial market project where I structured the initiative and oversaw key hiring decisions. As the project progressed, I identified discrepancies between planned and actual expenditures and raised these concerns with the business owners. Over time, I recognized that the cost structure of the offered product was unsustainable. Further investigation revealed that unallocated funds were being misused by one of the owners, which eventually led to the project's closure. This experience sharpened my skills in proactive risk management and financial oversight.
SESI - Serviço Social da Indústria
Set 2013 - Abr 2019 - 5 years and 8 months
Brasilia, Distrito Federal, Brazil · in office position
Languages: C++ (arduino), EV3-G
Skills and Tools:
I began at SESI in 2013 as a Competitive Robotics Team Coach, where I applied agile techniques to secure multiple regional championships across Brazil—including a vice-world champion title in England in 2017. Building on these successes, I was promoted to take on larger responsibilities. As a Regional Robotics Sub-operator, I organized the National Robotics Tournament—a three-day event hosting 30–40 teams, 400 students, and 80 coaches—overseeing logistics from judge recruitment to ensuring a smooth experience for over 2,000 visitors. Simultaneously, as the Regional Coordinator for the Midwest Region (Jan 2017 – Apr 2019), I managed projects from concept to execution by defining goals, managing budgets, and keeping teams motivated through methodologies such as Waterfall, Agile, Lean, and Six Sigma alongside SMART and OKRs. These progressive roles solidified my project management skills and my ability to lead diverse teams in high-pressure environments.
CNI - Confederação Nacional da Indústria
Jan 2014 - Mar 2016 - 2 years and 3 months
Brasilia, Distrito Federal, Brazil · in office position
Languages: English
Skills and Tools:
From January 2014 to March 2016, I served as the Regional Project Coordinator for Conexão Mundo at CNI/US-Brazil Connect. I coordinated a selective exchange program where the top 30% of students, identified through a competitive exam, received English immersion training from native speakers—culminating in a two-week exchange trip to the US. In 2016, I led a delegation of 10 students from three Brazilian states to Denver, Colorado, representing key industry bodies. I managed all communications with American coordinators and handled the complete logistics for their visit to Brazil—including air travel, hotel arrangements, domestic transport, and meals—as well as the US trip for the selected students. I also optimized project processes, reducing absenteeism by 80% through improved documentation and new operational procedures.

This portfolio only contains things I've produced for my own study, since some of what I've done is protected by an NDA with other companies.
Recently, I found it challenging to keep up with the wealth of high-quality articles published on platforms like MIT Technology Review. To tackle this, I began converting these articles into podcast episodes, narrated in a conversational style. I then upload them to a Spotify playlist, so I can listen to them anytime, anywhere. This approach helps me absorb dense content in a more accessible format that anyone can understand.Spotfy: TechTalk Insights
I'm unlikely to consider hybrid or on-site positions.
My salary expectations depend on the scope, workload, complexity and level of responsibility of the role. While compensation isn't everything, it should reflect the experience and commitment required to deliver excellence.
Yes, I'm well established in Porto, Portugal, but I'm open to evaluating relocation opportunities if the right fit emerges.
