@sibusisomsibiya
I build and operate cloud-native APIs, data pipelines, and web applications on AWS.
South AfricaWhat I'm looking for
I'm building Python backend services, REST APIs, and operational data pipelines at Totalityworks. I integrate OpenAI and Anthropic Claude APIs with structured outputs, streaming, rate limiting, and error retries.
Previously, I built scalable FastAPI services and ETL workflows at Clientele, and delivered Spring Boot and FastAPI microservices at NovatecSA. My work includes AWS deployments, Docker, GitHub Actions CI/CD, CloudWatch monitoring, and production incident support.
I've also developed Angular and Java Spring Boot features at Shaper, supported production platforms at Absa, and worked with Python data pipelines at ExploreAI. I enjoy building observable, tested services that reliably support real users and operational teams.
