Hiring Manager
Thoughtworks
Dear Hiring Manager,
Thoughtworks' commitment to delivering high-quality software at speed resonates with the DevOps culture I have built in my own teams. By migrating Tech3pillars Technologies' infrastructure to Azure and implementing a full CI/CD pipeline, we reduced deployment friction from weeks to daily. My experience orchestrating containerized environments and automating infrastructure provisioning positions me to support Thoughtworks' client delivery.
At Tech3pillars Technologies, I architected Kubernetes clusters that serve over 200 microservices while maintaining 99.99% uptime across production environments. Our shift to GitOps with Azure DevOps and Terraform improved change velocity and reduced incident blast radius, allowing feature teams to deploy safely.
Previously, as a Systems Analyst at Elevait Solutions, I partnered with engineers to codify site reliability best practices that reduced downtime by 40% and improved monitoring coverage. Bridging the gap between development and operations is where I thrive, and I appreciate Thoughtworks' focus on pairing delivery with sustainability.
