CURRENT PROJECTS / ORACLEFEB 2025 → PRESENT · SENIOR DEVOPS ENGINEER (SRE)
Four platforms.
Production responsibility.
My current Oracle work spans ECP, ECP-RT, OSDMC and ICON—connecting infrastructure code, controlled delivery and day-to-day reliability.
PERSONAL ENGINEERING SCOPE
Develop and review Terraform, Python, Bash and GitLab CI/CD code. Automate provisioning and OKE lifecycle operations with OCI Resource Manager across multi-region, multi-tenant platforms.
01 / CONNECTIVITYORACLE
ECP
Cloud platform & IoT connectivity
Infrastructure automation and operational support for a platform that connects cloud services with real-world devices.
- Provisioning and OKE lifecycle automation using Terraform, Python and Bash.
- Infrastructure and deployment-code development and review.
- IoT connectivity troubleshooting, including jitter and packet-loss analysis across carrier and satellite networks.
Explore implementation, operations & ownership ↗
Platform implementation
I develop Terraform, Python and Bash automation for provisioning and OKE lifecycle management. My work includes reviewing infrastructure and delivery code for multi-region, multi-tenant environments; application-code changes remain with the relevant developers.
Connectivity investigation
I troubleshoot ECP IoT connectivity across carrier and satellite networks and automate jitter and packet-loss analysis. The focus is on distinguishing network behavior from cloud or workload symptoms, rather than treating every failure as a deployment issue.
Real-time service support
I deploy LiveKit and troubleshoot WebRTC across ECP and ECP-RT. This complements the infrastructure work with service-level investigation.
Release qualification & lifecycle operations
Execute release qualification across cloud services, infrastructure components and edge artifacts, combining pipeline dry runs with tenant-lifecycle validation to prepare changes for controlled promotion.
Database change operations
Carry out procedure-led database migration and credential-rotation operations alongside platform image upgrades. Validate release prerequisites through health analysis, credential-expiry checks and monitoring-rule maintenance, coordinating application-level changes with the relevant owners.
02 / REAL-TIME SERVICESORACLE
ECP-RT
Real-time communications & release operations
Production delivery and qualification alongside hands-on LiveKit and WebRTC deployment and troubleshooting.
- Execute platform releases and upgrades across environments.
- Perform post-upgrade activation and qualification checks; coordinate defect resolution.
- Deploy LiveKit and investigate real-time communication behavior.
Explore implementation, operations & ownership ↗
Deployment execution
I participate in platform deployments and upgrades across environments, with responsibility for release execution and qualification. Release completion includes qualification, not simply a successful pipeline status.
Qualification and coordination
Post-upgrade activation checks and qualification tasks expose integration issues that require coordination with product engineering. I investigate failures and work with developers on defect resolution in partnership with the application owners.
Media-service operations
I deploy LiveKit and troubleshoot WebRTC behavior. Jitter and packet-loss analysis connects the user-facing communication symptom to the underlying network and service evidence.
Maintenance beyond feature releases
Execute patch upgrades and multi-region production deployments, verify scheduled OCI compute maintenance, and carry releases through post-upgrade activation qualification. Connect infrastructure lifecycle work with service readiness rather than treating pipeline completion as the end of a release.
03 / SERVICE OPERATIONSORACLE
OSDMC
Platform automation & operational monitoring
Cloud infrastructure engineering backed by recurring monitoring checks and production-service investigation.
- Provisioning and OKE lifecycle work within the four-platform infrastructure scope.
- Verify detection-rule status as part of operational monitoring.
- Handle service alerts, including identity-service connectivity investigation.
Explore implementation, operations & ownership ↗
Infrastructure contribution
Develop and review infrastructure and deployment automation using Terraform, Python, Bash and OCI Resource Manager, supporting provisioning and OKE lifecycle operations within the shared platform-engineering remit.
Monitoring and daily operations
Verify detection rules as part of recurring service operations, complementing dashboards with checks on the monitoring controls that support incident detection.
Incident investigation
Investigate identity-service connectivity alerts, correlate the available operational evidence and coordinate recovery with the relevant service owners.
Tenant capacity & change validation
Perform tenant storage-capacity changes with pre-change validation, tenant-status checks and post-change verification. Bring the same controlled execution discipline to capacity operations as to service releases.
Identity integration troubleshooting
Investigate partner-token generation failures and identity-service connectivity alerts, using operational evidence to narrow the affected integration and coordinate the next recovery action.
04 / PLATFORM ENGINEERINGORACLE
ICON
Infrastructure code & Kubernetes lifecycle
One of the four platforms covered by my current Oracle infrastructure and deployment engineering responsibilities.
- Develop Terraform, Python and Bash provisioning automation.
- Support OKE lifecycle management through OCI Resource Manager.
- Build and review infrastructure and GitLab CI/CD pipeline code for multi-region, multi-tenant platforms.
Explore implementation, operations & ownership ↗
Provisioning automation
Contribute Terraform, Python and Bash automation to repeatable platform provisioning through OCI Resource Manager, with infrastructure changes represented and reviewed as code.
Kubernetes lifecycle
Support OKE lifecycle management within a multi-platform engineering remit, applying infrastructure and deployment expertise to the Kubernetes environment while collaborating with application owners.
Delivery-code ownership
Build and review infrastructure and GitLab CI/CD pipeline code for multi-region, multi-tenant platforms, connecting provisioning workflows with repeatable delivery practices.
ENGINEERING DEPTH / SHARED ORACLE RESPONSIBILITIES
What I build, review and operate.
Eight areas of hands-on work behind the four platforms. Shared responsibilities across my Oracle role, from infrastructure implementation and design review to release execution and production recovery.
01Architecture & change review
Review the changes that cross system boundaries.
I review Terraform changes, pipeline approvals, IAM boundaries and schema migrations as part of OCI DevOps and Shepherd delivery. Custom promotion gates validate architecture integrations and detect configuration drift between staging, pre-production and production.
- Infrastructure and deployment-code review, with explicit environment context.
- IAM and schema-change checks before production promotion.
- Coordination with application owners where a change crosses team boundaries.
Focus: infrastructure design review, deployment engineering and integration readiness.
02Infrastructure automation
Turn provisioning and lifecycle work into code.
I develop Terraform, Python and Bash automation with OCI Resource Manager for platform provisioning and OKE lifecycle management across ECP, ECP-RT, OSDMC and ICON.
- Maintain repeatable infrastructure and deployment workflows for multi-region, multi-tenant platforms.
- Build and review the code that drives platform operations.
- Use the same engineering discipline for lifecycle work as for initial provisioning.
Deliverables: provisioning automation, infrastructure changes and Kubernetes lifecycle workflows.
03CI/CD & release execution
Carry a change from review to controlled promotion.
I build reusable GitLab CI/CD templates and shared libraries with security scans, linting and compliance checks. I own OCI DevOps and Shepherd production deployment and upgrade responsibilities within my role.
- Use promotion gates to validate integration assumptions and configuration consistency.
- Use Prometheus and OpenTelemetry health signals to validate deployments and trigger rollback.
- Coordinate release activities within approved change windows.
Deliverables: reusable GitLab templates, shared libraries and controlled promotion workflows.
04Release qualification
Test integrations and schema changes before calling a release complete.
I build Playwright-based Release Qualification automation and coordinate defect resolution. The work links release execution to integration behavior and schema-change validation.
- Automate repeatable qualification checks using Playwright.
- Investigate qualification failures and coordinate application fixes with developers.
- Complete releases within approved change windows.
Deliverables: RQ automation, qualification findings and coordinated release completion.
05Observability & service health
Make uptime, reliability and cloud cost visible.
I build Streamlit uptime and cloud-cost dashboards, Grafana SLO/SLI monitoring, and OpenSearch/Kibana threshold monitors with Slack webhooks.
- Use SLO and SLI views to connect service health to reliability targets.
- Bring logs, metrics and deployment-health signals into operational investigations.
- Make uptime and cost information accessible through focused dashboards.
Reported result: threshold monitoring and webhook alerting reduced detection time by 45%.
06AI-assisted SRE
Accelerate investigation while retaining human judgment.
I engineered an OpenSearch and Prometheus MCP correlation server with the SRE team and built custom Codex diagnostic workflows. I also built an AI review agent for infrastructure and deployment changes.
- Correlate log and metric evidence to support incident triage.
- Automate environment health reporting and paging; operate GenAI services.
- Keep human approval before production promotion and validate production actions.
Reported results: at least 75% less triage time and 50% less initial response time.
07Disaster recovery
Exercise recovery procedures, not just document them.
I standardized multi-region disaster-recovery runbooks and failover tests, validating replication and recovery across OCI block storage and Oracle AI Autonomous Databases.
- Maintain operational standard procedures and methods of procedure.
- Validate replication and recovery through failover testing.
- Coordinate recovery work across the relevant service and infrastructure owners.
Deliverables: DR runbooks, failover tests and operational procedures.
08On-call & cross-team execution
Own the operational thread through investigation and recovery.
I lead on-call incident, change and problem management. Telemetry correlation and cross-stack root-cause analysis connect the immediate response with longer-term operational improvement.
- Investigate across infrastructure, deployment and service layers.
- Coordinate application-code changes with developers while owning infrastructure and deployment work.
- Use operational findings to improve procedures and subsequent change execution.
Reported results: MTTD down 50%, MTTR down 30%, and incidents resolved within SLA improving from approximately 82% to 99%.
