About

I’m a hands-on security practitioner with experience across IR, threat hunting, IAM, and cloud hardening. My toolkit spans SIEM, EDR/XDR, and automation with Python/PowerShell. I enjoy turning noisy telemetry into action, and building pipelines that make secure the default.

  • Security Operations: IR, Threat Hunting, Log Analysis, Vuln Mgmt, Phishing Analysis
  • EDR/XDR: CrowdStrike, SentinelOne, Carbon Black
  • Automation: SOAR playbooks, Python scripting

Experience

Tata Consultancy Services (TCS) · Cybersecurity Analyst (Virtual Simulation)

Jun 2025
  • Improved access security posture by partnering with IAM consultants to define policy baselines, enabling cleaner role design and fewer exceptions.
  • Increased audit readiness by mapping IAM controls to compliance requirements (e.g., ISO 27001), producing clear implementable procedures.
  • Accelerated provisioning reviews by documenting identity governance workflows and decision trees for common scenarios.

AIG · Cybersecurity Threat Analyst (Virtual Experience Program)

Jun 2025
  • Raised threat visibility by triaging simulated alerts against CISA advisories, improving signal-to-noise for analyst review.
  • Strengthened remediation guidance by summarizing CVEs with business impact, helping teams prioritize patch actions.
  • Reduced ransomware drill recovery time by scripting a Python utility to test encrypted-zip recovery paths.

Deloitte · Cybersecurity Consultant (Virtual Simulation)

Jun 2025
  • Accelerated incident scoping by analyzing web logs to surface suspicious behavior patterns during a breach simulation.
  • Improved containment recommendations by isolating likely root causes and articulating response options.
  • Standardized decision-making by aligning actions to NIST guidance during tabletop exercises.

Mastercard · Security Awareness Analyst (Virtual Simulation)

Jun 2025
  • Lowered phishing exposure by assessing threat vectors and identifying vulnerable user cohorts.
  • Increased training effectiveness by designing role-based awareness modules for targeted teams.
  • Improved enterprise cyber hygiene by recommending actionable controls and behavioral nudges.

CloudNext Technologies · Secure Software & Cloud Engineer

Dec 2021 — Mar 2024 · Hyderabad, India
  • Safeguarded patient data by implementing secure coding (validation, encryption, OAuth/JWT, API security), achieving HIPAA/GDPR compliance across all app modules.
  • Reduced security incidents by 25% by configuring IAM roles, firewall rules, and multi‑cloud monitoring across AWS, Azure, and GCP.
  • Cut deployment misconfigurations by 40% by establishing a DevSecOps pipeline with automated scanning and secrets management.
  • Eliminated high‑risk flaws pre‑release by proactively testing, patching, and verifying remediation before production cutovers.
  • Enabled a 30% increase in user adoption while maintaining strict data protection by co‑designing secure telehealth workflows.
