Integrated security checks (e.g., static code analysis and vulnerability scanning) within the pipeline, ensuring secure and compliant deployments.
Containerization & Orchestration: Containerized multiple applications using Docker and managed them with Kubernetes. Enforced container image security policies (e.g., scanning images for vulnerabilities via JFrog Xray) to ensure a secure runtime environment while achieving high availability and fault tolerance.
Infrastructure Automaton: Automated infrastructure provisioning using Terraform and Ansible with strict role-based access controls (RBAC), ensuring secure and consistent deployments while reducing manual errors.
Cross-Team Collaboration: Partnered with development teams to embed DevSecOps practices, enabling secure integration of features and fostering a culture of shared ownership and accountability.
Service Reliability Standards: Defined and implemented service-level objectives (SLOs) and indicators (SLIs) to measure, monitor, and report system reliability and security compliance, aligning with SLA requirements.

Monitoring & Observability: Deployed and configured monitoring and logging tools

(Dynatrace, Splunk) with enhanced anomaly detection capabilities. Integrated audit trails and system event tracking to improve incident response and forensic analysis.

Incident Management Transience: Migrated 24/7 on-call schedules from PagerDuty to Xmatters, improving alert workflows and integrating incident management with root cause analysis (RCA) documentation.
On-Call Support: Proactively monitored systems and mitigated security vulnerabilities during 24/7 on-call rotations, ensuring system reliability and adherence to security protocols.
Security Enhancements: Strengthened system security by implementing identity and access management (IAM) best practices, monitoring privileged access, enforcing network security controls (e.g., Security Groups, NACLs), and conducing regular vulnerability scans and assessments.

HouseHappy - Portland, OR
DevOps/SRE

Task Automaton: Automated repetitive dev tasks (e.g., backups, security patches) at scale using Functions and Python scripts, reducing manual intervention and minimizing operational risks.
Operations Scripting: Developed Bash and Python scripts to automate tasks while embedding runtime security checks, improving system reliability and reducing attack surfaces.
Service-Level Standards: Defined and enforced SLAs, SLOs, and SLIs, integrating security metrics into reliability standards to ensure compliance with industry and organizational policies. • Incident Management & Uptime: Monitored systems for anomalies using advanced monitoring tools (Prometheus, Grafana, Splunk) and implemented automated incident responses, achieving consistent uptime and minimizing security breaches.
Cloud Resource Management: Conducted a full inventory of AWS and DigitalOcean resources, incorporating them into Terraform for security management and auditing.

Established secure IaC practices by enforcing environment segregation and encryption policies.

Capacity Planning: Evaluated system performance metrics to forecast demand and prevent bottlenecks. Integrated autoscaling policies to maintain both performance and secure workloads under varying loads.

On-Call Support: Responded to incidents during 24/7 on-call rotations, addressing performance issues and mitigating security risks. Conducted post-incident reviews to ensure corrective actions were implemented securely.
Configuration Management: Automated configuration processes with Ansible, embedding compliance checks for secure server provisioning and maintenance.
Maintained thorough system documentation, including security configurations and troubleshooting workflows, enabling efficient knowledge transfer and secure handovers.
Monitoring & Observability: Integrated observability tools (Prometheus, Splunk, Dynatrace) with security alerting features to enhance visibility into application performance, security incidents, and system health, reducing MTTR and improving proactive detection.
