BACKEND × OFFENSIVE SECURITY
Build systems.
Understand their limits.
I build systems at EPEC and focus on offensive security: investigating vulnerabilities, connecting findings and understanding their impact.

From archive to process: research into infostealers and evasion, presented at GISSIC.
About the talkLab research presented at the 5th GISSIC Cybersecurity Conference. A practical look at infostealers, evasion techniques and the abuse of legitimate processes.
Road to HackerTechBackend & Software Engineer at EPEC. Systems connecting devices, data and people.
CURRENTLY IN DEVELOPMENT
Architecture and development of a platform bringing together data acquisition, processing and analyser operations.
From database design to service integration.
System architecture and development connecting data acquisition, persistence and an operational interface. A multi-layer solution for managing analysers and providing visibility into readings and system health. System and database architecture, backend development and service integration. The work spans resilient measurement collection, asynchronous processing and an authenticated interface for managing devices and querying data. The focus is service continuity, traceability and maintainable architecture.
A web platform for exploring energy consumption and efficiency, correlating measurements and identifying patterns and anomalies.
A backend service that automates meter queries, retrieves readings and sends responses back to the management system.
A web application tracking meter queries, timestamps and responses for operational traceability.
A tool that compares information across sources and highlights inconsistencies between systems.
Three personal projects exploring software, automation and networks.
A desktop application for managing customers, suppliers and stock in a clothing store.
Image capture, processing and interaction with an Android instance through ADB.
A Python daemon that records Internet interruptions and generates outage statistics.
Skills connecting my software engineering experience with my work in security.
System and database design, APIs, service integration and asynchronous processing.
Scripting, information analysis and tools to automate tasks and identify inconsistencies.
Reconnaissance, vulnerability analysis and attack chains in labs, practice machines and CTF competitions.
Documenting findings, presenting research and collaborating on technical experiences for the community.
I’m Mateo/r4ch. Backend development is my starting point; offensive security is my direction. I’m interested in finding vulnerabilities, understanding how they connect and communicating their impact. I practise in labs and competitions, and share what I learn through talks and technical experiences.
