Technical Overview
Senior Cyber Security Engineer focused on the full data protection stack - DLP, data classification, data discovery, and CASB. I design and operate large-scale endpoint and network DLP environments, map vendor product requirements to real capabilities, and build the operational layer around them: PoC plans, fit analysis, classification policy design, administrator enablement, field-driven product validation, and product advisory for organizations evaluating data protection technologies. I work across the infrastructure that carries this data: Windows/Linux servers, Active Directory, MongoDB, ElasticSearch, FortiGate, and packet-level network analysis.
Professional Experience
Feb 2023 - Present
Senior Cyber Security Engineer
CRYPTTECH - Cyber Security / Artificial Intelligence
- Deployed and operated enterprise endpoint and network DLP environments; configured classification and discovery policies across large-scale deployments covering multiple data categories and enforcement paths.
- Designed and tuned ICAP inspection flows and Secure Mail Gateway policy logic; reduced noise by refining classification rules and policy enforcement paths based on packet and log evidence.
- Built PoC validation frameworks mapping vendor DLP requirements to production capabilities; delivered fit analysis and trade-off documentation used in multiple product evaluations.
- Continuously validated product behavior in customer-like environments; reproduced bugs, documented impact, and opened Jira issues for development teams with logs, packet evidence, and clear reproduction steps.
- Operated ElasticSearch and MongoDB clusters supporting security data platforms; used query and log analysis for real-time security event correlation across Windows and Linux environments.
- Prepared administrator training materials, technical documentation, and automation scripts (Bash, PowerShell, Python) to standardize repeatable operations.
