What I do
I help teams ship safer software through secure architecture reviews, source code review, vulnerability validation, threat modeling, and CI/CD-integrated security automation.
I’m Luis Rodriguez Castro, an AppSec engineer focused on building scalable security systems, automating vulnerability management, and helping teams ship secure software without slowing down.
I work at the intersection of software engineering and security, with a bias toward building useful things instead of just filing tickets.
I help teams ship safer software through secure architecture reviews, source code review, vulnerability validation, threat modeling, and CI/CD-integrated security automation.
I care about security that scales. That usually means reducing manual work, designing clear controls, and giving developers guardrails that are easy to adopt.
AppSec, offensive security, low-level security, threat modeling, secure tooling, cloud architecture, and learning how systems actually work under the hood.
A practical mix of security engineering, software development, and cloud knowledge.
Built automation to process security findings, reduce manual triage, and route remediation work more efficiently.
Designed scalable scanning workflows using AWS services and automated domain discovery to keep targets fresh.
Worked on a CLI tool using Go to help security teams manage vulnerabilities, track remediation progress, and generate reports for stakeholders.
Performed STRIDE-based analysis for modern application and tokenization architectures, mapping threats to actionable mitigations.
Performed application security efforts with an emphasis on practical controls, architecture review, secure code review, vulnerability management, tool development and secure engineering collaboration.
Built and maintained security tooling in Python, Node.js and Go, performed source code reviews, validated findings, and contributed to scalable security processes across engineering teams.
Expanding into the Cloud with AWS and IAC-based infrastructure, deeper secure design work with threat modeling, exploring low-level security concepts to better understand how to secure complex systems and AI security topics as they evolve.
