• Build backend services that handle large-scale data requests securely and reliably.
• Develop reproducible, recoverable pipelines for large genomic inputs.
• Write parsing and transformation logic for third-party vendor outputs.
• Harden pipelines against failures so they recover without manual intervention.
• Optimize pipeline performance as data volume grows.
• Design PostgreSQL schemas and data models for genomic and health data.
• Architect AWS infrastructure using infrastructure-as-code (CDK or CloudFormation).
• Set up secure storage systems for sensitive healthcare data.
• Collaborate with the frontend engineer on deployment workflows.
