    DevOps Engineer @ Talentship

    Own the AWS platform behind dozens of customer-facing production sites — security, cost, reliability, and the migrations in between.

    Platform & migrations

    • Migrated application infrastructure from AWS OpsWorks to Amazon ECS, improving scalability and containerized workload management.
    • Moved domains from Cloudflare to Route 53 + CloudFront with AWS WAF controls for better security and global delivery.
    • Migrated ownership of two production domains with zero downtime.
    • Upgraded a large legacy Jenkins estate (v2.396 → v2.462), closing known security vulnerabilities.
    • Upgraded RDS PostgreSQL (14.10 → 14.15, 16.1 → 16.6), Java 17 → 21 and Tomcat 9 → 10.1 ahead of end-of-support; rotated RDS certificates across production.

    Infrastructure as Code & scale

    • Designed highly available, secure AWS infrastructure with Terraform and Auto Scaling.
    • Built reusable Terraform modules to standardize provisioning across apps and environments.
    • Applied vertical and horizontal scaling strategies for peak-season traffic.
    • Maintained 99.9% availability across 40 production websites.

    Security & cost

    • Rolled out AWS Shield Advanced + WAF against bots, SQL injection, scraping and DDoS.
    • Integrated Trivy and Checkov into security workflows; remediated OS and container-image CVEs.
    • Cut AWS spend by ~16% across 15 accounts through rightsizing, idle-resource cleanup, RIs and Savings Plans.

    AI-assisted operations

    • Built a custom AI Incident Bot that analyzes logs and ops data — 50% faster root-cause analysis.
    • Automated ops workflows and docs with Claude Skills, GitHub Copilot, Python and Shell.
    • Implemented AI guardrails for secure, compliant use of AI tools in engineering.
