Rajkumar Adepu

I build reliable systems and break them before attackers do.

Production reliability, cloud automation, observability, incident response, and offensive security thinking brought together for infrastructure that stays fast, secure, and recoverable.

Focus Reliability + Security
Mode Hardening Kubernetes ingress...
Response 24/7 incident mindset

Core strengths

Engineering for uptime, velocity, and trust.

01

Site Reliability Engineering

SLOs, alert hygiene, incident command, capacity planning, disaster recovery, and error-budget thinking for systems that keep their promises.

02

DevOps & Platform Automation

CI/CD pipelines, infrastructure as code, container orchestration, release governance, and self-service paths that remove toil from delivery.

03

Cybersecurity Engineering

Secure baselines, identity controls, vulnerability management, logging strategy, cloud posture, and defense-in-depth across modern infrastructure.

04

Ethical Hacking

Recon, web application testing, exploitation labs, reporting, threat modeling, and practical attacker empathy that improves real-world defenses.

Technical stack

Tools I use to ship resilient infrastructure.

Cloud & Infrastructure

AWS Azure Linux Terraform Ansible Docker Kubernetes Nginx

Automation & Delivery

GitHub Actions GitLab CI Jenkins Bash Python Helm Argo CD GitOps

Security & Observability

SIEM Burp Suite Nmap Metasploit Prometheus Grafana ELK Wazuh

Operating method

A practical loop for stronger systems.

I combine reliability habits with adversarial testing: understand the system, observe the weak points, automate the fixes, and keep recovery paths rehearsed.

Detect

Turn logs, metrics, traces, and security events into sharp signals.

Harden

Reduce attack surface and enforce secure infrastructure defaults.

Automate

Replace manual recovery and release steps with repeatable pipelines.

Recover

Practice incident response, rollback, backup, and disaster recovery paths.

Selected project themes

Portfolio pieces that show range.

Observability 01

Kubernetes Reliability Dashboard

Prometheus and Grafana views for pod health, saturation, deployment risk, SLO burn, and noisy-alert cleanup across a container platform.

Kubernetes Prometheus SLOs
Security 02

Zero Trust CI/CD Pipeline

Policy checks, secret scanning, container image validation, signed artifacts, and least-privilege deployment flow for secure releases.

GitOps Trivy OPA
Offense 03

Web App Attack Lab

Ethical hacking lab covering recon, OWASP Top 10 testing, exploitation notes, remediation guidance, and executive-ready reporting.

Burp Suite OWASP Reporting
Automation 04

Incident Response Runbooks

Automated triage scripts, escalation paths, timeline capture, postmortem templates, and recovery commands for faster incident handling.
