Work Experience
DevOps Engineer
2025 - 2026
Yara International - Africa and Asia
- Built and operated a change data capture platform on AWS DMS, running 22 production replication tasks and 44 endpoints across nine countries and streaming around 40 million change records a month from PostgreSQL RDS into an Amazon S3 data lake.
- Prepared 20+ production RDS instances for logical replication with custom parameter groups and WAL limits, rolled out in three-country batches with zero unplanned downtime.
- Led the root cause analysis of a replication slot outage that filled database storage, then added slot-lag and storage alarms that cut detection time from seven hours to under 10 minutes.
- Provisioned Amazon MWAA staging and production environments with Terraform, including private networking, Secrets Manager integration, and a custom HTTPS domain for the Airflow UI.
- Designed a hybrid architecture that offloaded dbt and ML workloads from MWAA workers to AWS Fargate via astronomer-cosmos, projecting around 45% savings in Airflow compute costs.
- Enabled Amazon Bedrock for the data science team with least-privilege IAM for Claude models and guardrails that anonymized 12 PII types in a customer-facing translation pipeline.
