Working as a Platform Engineer on Codurance’s AI Interviewer project, implementing AI improvements impacting millions of users worldwide. Leveraged AWS Lambda, RDS, SQS, and S3 to deliver high-impact solutions integrating with large language models. Collaborated with a multidisciplinary team of 20+ professionals including 5 site reliability engineers. Utilized Python 2.7/3.1, Gitlab CI/CD, MySQL, and Pyramid framework. Planned and implemented OS migration and fail2ban to enhance security, managing VPC security with public/private subnets for EKS, ECS, and RDS. Scaled backend to 12–20k requests/minute with 99.92% availability and 38% reduction in P95 latency. Managed IAM configurations reducing unnecessary privileges and users by ~20%. Delivered 15–20 deploys/week with 97% pipeline success rate. Implemented observability reducing MTTR by 80%. Achieved cost savings through autoscaling, off-hours shutdown, S3 lifecycle policies, and CDN implementation increasing availability from ~95% to 99%. Enhanced security with Docker multi-layer builds and scanning in CI/CD. Created Datadog dashboards reducing support requests by 30% and improved tracing reducing RCA time by ~10%.

Enhanced infrastructure as code (IaC) for an Ethereum-based blockchain project. Analyzed and applied security best practices to IaC and CI/CD pipelines. Developed automation solutions and ensured quality in development processes. Implemented database proxy layer for blockchain microservice, updated Cloudformation code, automated secrets creation, and created fine-grained roles. Achieved 100% adoption of spot instances for batch jobs reducing compute costs by 22%. Reduced logs and CI costs by 30% and 20% respectively. Increased security posture by reviewing IAM access privileges.

Collaborated with a team of 20+ developers on cloud and database migration, cost-saving (FinOps) and security (SecOps) strategies. Supported development and production clusters, implemented security best practices, enhanced networking layer security with service mesh/proxy design, improved observability with ElasticSearch, and conducted load testing. Managed CI/CD pipelines with Docker scanning tools. Handled network monitoring with 200+ tickets/quarter and ~95% CSAT. Achieved ~25% compute cost reduction through rightsizing and ~20% EC2 cost reduction via Savings Plans. Reduced image storage costs by ~70% with registry cleanup policies. Implemented Docker scanning tools like Trivy, enhanced disaster recovery with Kubernetes and Helm, and improved software availability with Cloudflare CDN. Managed database connections and IAM with least privilege.

Worked in a Scrum team of 5 to maintain and improve a system for mapping investment opportunities in construction projects. Managed Kubernetes cluster and a Flask microservice. Delivered observability stack and CI/CD pipelines improving SDLC. Optimized security by implementing SSO with Keycloak, setting coding standards, and creating testing environments. Automated user management and login with Keycloak SSO.
