Hi, I'm pSacramento!

I’m an independent researcher focused on Bitcoin, privacy, digital payment systems and digital freedom.

I was born in South America, and I now work in the public sector in a Central European country, advancing the digitalization of payment systems for government offices.

On my free time I'm most of the time reading, writing or building software with AI.

Professional Experience

My professional background began in UX design, where I worked on digital products and user experiences for global companies. That experience taught me how to connect research, usability, systems thinking, and real-world user needs.

Over time, my work expanded beyond design into research, especially in areas where technology and human freedom intersect.

Academic Background

I bring an academic background that combines both the social sciences and technical understanding. This combination has shaped the way I approach my work, inspiring curiosity about people, systems, and human behavior, as well as the interplay between technical infrastructures and social impact.

My Relationship With Bitcoin

I’ve been involved with Bitcoin since 2020, and it has had a profound impact on my life. It pushed me to grow in SO MANY areas, both personally and professionally. Most importantly, it gave me a new lens through which to think about technology, responsibility and the future.

Over time, it became clear to me that Bitcoin has a chance of becoming a foundational part of the future of money and freedom in the digital age.

I want to play my part in making this future a reality.

Funded Projects and Research

My work has been supported by the Human Rights Foundation’s Bitcoin Development Fund two different times. Through that support, I contributed to the Open Source projects and carried out research projects such as my work on Brazil’s Pix system and the lessons it offers for Bitcoin and digital payments.

These opportunities allowed me to combine research, writing, and product thinking in projects that aim to strengthen freedom technology and improve understanding around money, privacy, and infrastructure.

Hackathons and public speaking

I write and speak about Bitcoin, privacy, digital payments, AI and digital freedom.

2026

At the Freedom Tech Summit in Prague, I presented Privacy as Infrastructure: What Brazil's Pix Teaches the World. The talk was based on my research into Brazil's Pix payment system and what it can teach us about privacy in digital payments. The talk with Nick Anthony afterwards was the highlight of the event for me!

I also took part in AI Hack for Freedom II in Nashville. I worked on a project focused on transnational repression against Chinese dissidents.

2024

I presented at dev/hack/day in Prague, where I shared my work with other developers and people working on Bitcoin projects.
