Sunith Senthil K

Software Engineer | Backend, Cloud Infrastructure, DevOps, Observability

Bengaluru, India

Hi, I’m Sunith, a software engineer focused on backend systems, cloud infrastructure, DevOps, and observability.

My work has involved building production systems, automation workflows, deployment pipelines, and monitoring platforms at Oracle.

I have worked across Python, Django, React, Kubernetes, Helm, Jenkins, Redis, Celery, Grafana, Prometheus, and Oracle Cloud Infrastructure.

I care about reliability, clarity, and engineering workflows that help teams move faster with fewer operational bottlenecks.

This site brings together my experience, projects, technical skills, and writing in one place.

About

Backend, cloud, and platform engineering focus

My experience spans production engineering work at Oracle across backend systems, automation, CI/CD modernization, observability, and cloud-native infrastructure. I have worked on production systems involving incident monitoring, workflow automation, deployment modernization, and observability for large-scale internal platforms. My work focuses on building reliable systems, automating repetitive workflows, improving developer productivity, and working across backend, infrastructure, and cloud-native technologies.

The work is centered on reliability, automation, developer productivity, and cloud-native systems. That includes backend services, CI/CD modernization, observability dashboards, alerting workflows, and infrastructure-oriented tooling for production teams.
