What's slowing you down?
Pick the one closest to your situation. You'll see what we'd do first, how long it takes and how we'd work together.
Cloud cost optimization
FinOps, rightsizing and DevOps on AWS and GCP
- Read-only access to your billing and infrastructure
- A ranked list of savings, with the risk of each
- Fix the top three safely, one by one
Six things we do well
One team for the work that keeps your platform fast, affordable and audit-ready.
How a project actually runs
No black box. Each stage ends with something you receive, signed off by the person who built it.
A 30-minute call
You talk to an engineer, not a salesperson. We tell you plainly whether we're a good fit.
Written plan
We study your systems and write down scope, risks and the team.
Working MVP
Weekly demos on your own environment. You see progress every Friday.
Run and improve
Monitoring, fixes and a planned major release each quarter.
Invigorate Healthcare: a vitals tracking and preventive health platform, built on AWS from day one.
We built the web and mobile apps in React and React Native with a Python backend, on a multi-account AWS setup: a shared VPC, ECS Fargate and App Runner pipelines from Bitbucket, and RDS PostgreSQL. The team also got a written coding standards guide.
We build our own products too
The same team that works on client projects runs two products of its own. We use what we learn from running them in every engagement.
Quick commerce for Sivakasi: groceries from local stores, delivered within 6 km. A customer app and a delivery-partner app, built in React Native.See how it works →Industries we know
The people on your project
The team you meet in the first call is the team that writes your code.

Harshitha Jeyarathinam
“Strong architecture is the base for lasting products.”

Jeevittha
“Quality is a habit, not a phase.”

Santhosh
“Code by day. Lift by evening. Grow every day.”

Yalini
“Small steps every day lead to big dreams.”

Soundarya
“Learn by doing. Improve by questioning. Grow by solving.”
Are we a good fit?
We'd rather say no early than waste your time.
- You run real systems on AWS or GCP and want them cheaper, safer or faster
- You want named senior engineers, not a rotating bench
- You can give us access and a decision-maker for weekly check-ins
- You only need the cheapest hourly developers
- You want a big agency with hundreds of people on one account
- You need engineers on-site at your office every day
Start with a 2-week paid pilot
A fixed-price pilot on one real problem. If you continue, the pilot fee is credited to the full project.
Built in Sivakasi
Sivakasi is a town of printers and manufacturers. People here are known for careful, on-time work, and that's how we run software projects too.
A smaller town means lower overheads and a team that stays together for years. You won't meet a new engineer every quarter.
Working hours that overlap with yours
Common questions
Who is Onruyl?
A software engineering company based in Sivakasi, Tamil Nadu, founded by a cloud architect with 12+ years of experience. We focus on cloud cost, DevOps, security and AI engineering.
Which companies do you work with?
Startups and mid-size companies in fintech, healthcare, logistics and e-commerce, in India, the Middle East, the UK and the US.
How do you charge?
Fixed-price audits and pilots, milestone billing for fixed-scope projects, and monthly rates for dedicated engineers. See engagement models for details.
Will the same engineers stay on my project?
Yes. The people you meet on the first call are the people who work on your project, and every deliverable carries their name.
How do you handle security and access?
We start with read-only access, follow least-privilege rules, and sign NDAs and data processing agreements where needed. We follow SOC 2-aligned practices: encryption, audit trails and regular security reviews.
Can you work in our time zone?
Yes. We keep daily overlap with UK and Middle East clients and a fixed evening call window for US clients.
