I've built and deployed serverless REST APIs at AzubiAfrica using AWS Lambda, API Gateway, DynamoDB, AWS SAM, and GitHub Actions. My event registration API runs at $0 within the AWS Free Tier and includes automated validation, unit testing, OIDC-based CI/CD, and CloudWatch monitoring.

I also delivered a serverless task management API with full CRUD functionality, troubleshooting Lambda proxy integration and IAM permission issues to restore end-to-end operations. For a multi-tier AWS deployment, I designed a four-tier architecture using EC2, S3, CloudFront, ALB, ACM, IAM, and CloudWatch, while automating releases from hours to minutes.

Alongside cloud engineering, I review and quality-assure AI annotation work at Trustscale.ai, maintaining a 98% QA pass rate across 50–100 tasks weekly. Previously at Invisible Technologies, I audited AI-generated responses, standardized annotation guidance, and helped prevent potential downstream model failures.

I'm grounded in AWS cloud computing, AI, Python, Linux, CI/CD, security, observability, and practical troubleshooting. My background in biodata analytics and computational genomics also strengthens my analytical approach to building reliable systems.
