Olaleye Lekan Joseph

I’m a Software Security Engineer (SecOps / DevSecOps) with 3+ years of experience designing and deploying production-ready security tools, hardening web applications, and embedding security into CI/CD pipelines. I translate security research into practical, automated defenses that reduce real deployment risk.

In my work, I’ve designed and shipped 5+ security tools—like a network vulnerability scanner (Nmap + MITRE ATT&CK mapping), log analyzer, password strength analyzer, SSL/TLS certificate checker, and file integrity monitoring using SHA-256/512/MD5. I harden backends with OWASP-compliant input validation, CORS policies, and rate-limiting controls, and I automate SSL/TLS certificate chain verification with expiry monitoring and TLS cipher-suite grading.

I also build secure authentication and API access patterns, leveraging OAuth2/JWT, token rotation, and privilege-separated access control. From threat modeling and code reviews to SAST/DAST scanning and secrets detection in CI/CD, my focus stays on shipping secure systems—supported by OWASP-aligned AppSec practices and cloud security across AWS, Azure, and GCP.
