Hi, I'm Peterson Oaikhenah 👋

Senior Software Engineer | Backend, Cloud, Data & AI Systems


About me

I design and build scalable backend systems, data pipelines, AI agent workflows, and cloud-native architectures that support high-performance products and analytics platforms.

I have 8+ years of experience across backend engineering, cloud operations, distributed systems, serverless architecture, DevOps, and data platforms. My work often sits where product reliability, infrastructure, automation, and business-critical data meet.

  • Build REST and GraphQL APIs, microservices, event-driven systems, and serverless workloads.
  • Design and operate AWS-based systems using Lambda, ECS/Fargate, Glue, Airflow, DynamoDB, S3, IAM, CloudWatch, Terraform, and CI/CD.
  • Develop data and ML workflows for segmentation, recommendations, analytics, and operational reporting.
  • Improve reliability through observability, alerting, performance profiling, production support, and incident follow-through.
  • Use AI-assisted engineering and agent workflows to speed up debugging, testing, code review, and delivery.

What I focus on

  • Backend engineering with Python, Node.js, TypeScript, and Go.
  • Cloud-native systems on AWS.
  • Data engineering, workflow orchestration, and analytics pipelines.
  • AI agent workflows, LLM evaluation, and production reliability.
  • Serverless systems, distributed architecture, and DevOps automation.
  • Technical writing for backend, cloud, and AWS builders.
