HARIOM SINGHDevOps Engineer Portfolio
I'm Hariom Singh, a DevOps & Cloud Engineer and Project Engineering Lead at Saarthix. I hosted and run the whole Saarthix platform on my own: edge, load balancers, API gateways, Kubernetes, CI/CD and observability. I built it to be reliable and to cost as little as possible.

From commit to production.
Every push runs through a pipeline: lint, test, scan, build, push, deploy, verify. It rolls back automatically if anything fails. Press the button to run it.
Production-grade, startup budget.
I kept monthly spend as low as possible without dropping reliability. These are the main areas I optimized.
- 01Right-sized compute, with ARM/Graviton and spot capacity where it fits
- 02Self-hosted Nginx/Kong gateway instead of paid managed gateways
- 03CDN caching at the edge, which cut origin egress
- 04Container bin-packing and autoscaling down to the floor
- 05Self-managed open-source observability (Prometheus, Grafana, Loki)
- 06Tags and budgets with alerts, so cost is tracked like any other SLO

The Saarthix journey.
From the first commit to a production platform run by one person, in six steps.
Build
Spring Boot microservices and a React frontend, built with deployment in mind from day one.
Containerize
Multi-stage Docker images and one compose file, so every environment is identical.
Automate
Terraform for the infrastructure and a CI/CD pipeline that tests, scans and ships on every push.
Expose
CDN + WAF at the edge, an L7 load balancer, and an API gateway as the single front door.
Orchestrate
Kubernetes with autoscaling, self-healing pods and Prometheus/Grafana on everything.
Harden & Optimize
Least-privilege IAM, secrets in Vault, ARM/spot compute: secure, at the lowest possible cost.
From shipping features
to running the platform.
I started out writing the product. Then I took over everything it runs on. Now I want to do that full time, building platforms that are secure, observable, automated and cheap to run.
Project Engineer Lead
- Led full-stack product engineering (Spring Boot + React)
- Owned the architecture and technical decisions
- Mentored the team, ran sprints and code reviews
- Took the product from idea to production
DevOps / Cloud / SRE
- Hosted and run the entire Saarthix production stack
- Load balancers, API gateways, reverse proxies, TLS
- CI/CD pipelines with security scanning built in
- Observability, incident response, cost engineering
🛡️ DevSecOps
CI/CD with security built in: scanning containers, secrets and Kubernetes, tuning the WAF, IAM governance and compliance guardrails.
☁️ Cloud Engineering
Secure, low-cost cloud environments on AWS and GCP: landing zones, networking, IAM, migrations and right-sizing compute.
📈 Site Reliability
Keeping systems up with Kubernetes, observability stacks, incident handling, root cause analysis and automation that removes repetitive work.
🤖 Infra Automation
Terraform, Ansible playbooks and Bash, Go and Python tooling that turn manual ops work into one command.
Let's build
something reliable.
I'm open to DevOps, Cloud, SRE and Platform Engineering roles where reliability, security and automation matter.
