01 — About

Software that earns its keep.

I am Arun Babu, a web developer and software enthusiast from Kerala by way of Mumbai. I have worked across product companies, a development cell and a large enterprise, which taught me to value both the code and the people who depend on it.

5+ Years in application development
5,000 Daily banking data transfers supported
99.5% Platform uptime maintained at TCS
24 Public repositories on GitHub

How I got here

I started with PHP full-stack work at the SIES SDC Cell while studying in Mumbai, then spent nearly three years at Tata Consultancy Services building integrations and keeping a banking data platform healthy. Later, at Manappuram Finance, I worked on moving an internal application from .NET to FlutterFlow.

Since 2025 I have been building independently: Symmetry, a medical research platform, a 3D GIS of Kerala and smaller experiments around AI assistants and developer tooling. I am open to backend, full-stack and integration roles in Bengaluru, Mumbai, Pune, Kochi or remote.

Backend Full-stack Integration Open source
01

Write for the next reader

Code should be well structured and readable. Small, independent and modular pieces are easier to test, change and hand over.

02

Ship with confidence

Testing is not optional. I aim for secure, robust services that fail gracefully instead of crashing, and I automate the checks that catch problems early.

03

Build for real people

Agile delivery, sensible backward compatibility and clear interfaces matter. The best automation is the one that removes a manual chore from someone's day.

02 — Experience

Where I have worked.

Five and a half years across enterprise integration, application modernisation and independent product work.
