Hi, I'm

Jesús Osbaldo Ojeda Aké

Backend-Oriented Full Stack Developer

Backend-oriented full stack developer with production experience building authenticated APIs, event-driven systems, and scalable services with Node.js and .NET. I currently lead digital transformation at NR Proyecta, where I designed automation systems and BI dashboards that eliminated 30+ hours of manual work per month. Previously, I led technical decisions for a 4-person team on a healthcare-sector backend system. I'm currently expanding my profile into cybersecurity engineering.

Projects

Some of the projects I've worked on, both production and personal.

Specter EDR

Specter EDR

Completed

EDR (Endpoint Detection and Response) solution built from scratch, where I combine software development and cybersecurity. A Rust agent monitors system processes in real time, applies detection rules (abnormal memory usage, non-whitelisted processes), assigns severity, and streams them to a backend that persists and broadcasts them live to a dashboard. 100% read-only design: it only observes and reports — it never kills processes or modifies the system.
