What I'm looking for

I’m looking for a role where I can modernize and harden embedded security stacks—PKI, TLS/SSH, OpenSSL/OpenSSH—while driving CVE remediation, compliance, and audit-ready security improvements for carrier-grade systems.

I’m a Senior Embedded Security Engineer with 12+ years in embedded C/C++, Linux system software, and cryptographic security for telecom platforms. At Tata Consultancy Services, I support Ericsson CPP security subsystems on 8200/8300 nodes running OSE RTOS and Embedded Linux, helping deliver hardened carrier-grade infrastructure.

I led OpenSSL 1.0.2d → 3.0.14 modernization across 15+ components, remediating 50+ CVEs, and OpenSSH 8.1p1 → 9.6p1 with 20+ vulnerability fixes while enforcing modern algorithms. I build PKI lifecycle capabilities (X.509, CRL, CMPv2, SCEP, trust-store design), implement TLS/SSH hardening and mutual authentication, and drive compliance through 3GPP security requirements, CVSS 3.1 impact assessments, and SCA-based risk and license checks.
