Executive Summary
Project overview and engineering context.
Certificate lifecycle automation for discovery, expiration tracking, renewal coordination, and service reliability.
Project Challenge
The operational challenge.
Certificate expirations were tracked manually, creating avoidable outage risk and inconsistent renewal ownership.
Solution Architecture
The engineering response.
Implemented certificate discovery, expiration monitoring, alerting, ownership mapping, and renewal workflows for critical services.

My Role
Engineering role and implementation focus.
SRE / Infrastructure Automation Engineer
- Built certificate discovery across endpoint and DNS inputs.
- Tracked expiration windows and service ownership for monitored endpoints.
- Implemented 30, 15, and 7 day alert checkpoints before certificate expiry.
- Routed renewal visibility to accountable service owners.
- Reduced expiry risk through proactive review cadence.
- Created repeatable renewal coordination workflows for critical services.
Environment & Challenges
Environment, inputs, and technical challenges.
Environment
Environment scope
- Internet-facing and internal service endpoints requiring certificate lifecycle visibility.
- DNS and endpoint discovery inputs used to account for inventory drift.
- Renewal ownership coordinated across infrastructure and service teams.
Challenges
Technical constraints
- Certificate ownership was not continuously maintained across all services.
- Manual tracking created avoidable outage risk near expiration windows.
- Discovery needed to cover both known inventories and live endpoint behavior.
Implementation
How the solution was implemented.
Discovery and tracking
- Built certificate discovery across endpoint and DNS inputs.
- Tracked expiration windows and service ownership for monitored endpoints.
Alerting workflow
- Implemented 30, 15, and 7 day alert checkpoints before certificate expiry.
- Routed renewal visibility to accountable service owners.
Reliability controls
- Reduced expiry risk through proactive review cadence.
- Created repeatable renewal coordination workflows for critical services.
Technologies Used
Tools and platforms.
Core technologies used to design, implement, and demonstrate the project.
Project Impact
Why it mattered.
- Lowered customer-facing outage risk from unmanaged certificate expiration.
- Made renewal ownership visible before urgent escalation windows.
- Improved operational confidence for internet-facing and internal services.
Lessons Learned
What shaped the next build.
- Certificate ownership must be maintained continuously, not only during renewals.
- Discovery should include DNS and endpoint checks because inventories drift.
- Alert timing matters; too early is ignored, too late becomes an incident.
