/ About Me
Hi, I'm Richard Borges, a back-end engineer and cyber-defence practitioner from Brazil. I architect mission-critical systems and help defend them against advanced persistent threats.
I started coding at 14. By 17, I had joined a corporate Red Team, where I spent five years in offensive security. Today, my work spans cyber defence, incident response, critical-system resilience, and back-end architecture in high-pressure environments. Some operational work is intentionally described at a high level due to confidentiality, safety, and attribution constraints.
I have reinforced back-end architectures in financial-sector environments, aligning systems with zero-trust principles, high availability, and graceful degradation under hostile traffic.
I am also deeply involved in the open-source gaming community, contributing to projects such as CFX.re (FiveM, RedM) and Open.mp. Resilient architecture, clean code, and security-first thinking are not trade-offs. They are the foundation.
Sensitive operational references are available under appropriate confidentiality conditions.

/ Public Impact & Records
A strategic overview of the environments, responsibilities, and public-facing work that define my track record across cyber defence, critical systems, and resilient back-end architecture.
National Critical Infrastructure Defence
Critical Infrastructure Defence
Participation in the defence of national-level critical infrastructure during coordinated hostile activity, with responsibility centred on continuity, stability, and operational resilience in high-pressure conditions.
Advanced Threat Containment & Recovery
Coordinated Cyber Operations
Collaboration with international cyber-security teams to trace and contain targeted corporate asset lockouts, reinforcing visibility, coordinated response, and rapid operational recovery.
Financial-Sector Back-end Architecture
Strategic Back-end Architecture
Architectural reinforcement of back-end systems in financial-sector environments, aligned with zero-trust principles, high availability, and graceful degradation under hostile traffic.
Open-Source Contributions in Gaming Infrastructure
Public Technical Contribution
Long-term contribution to major gaming communities through projects such as CFX.re and Open.mp, supporting infrastructure relied upon at scale by public-facing ecosystems.

My current focus is institutional work, but I remain open to non-profit open-source collaboration.
