Hi, I'm Aalok Kumar.

I build software where money and tax have to be right.

Backend engineer at Tinvio, building Jaz, a cloud accounting platform for businesses in Southeast Asia. I don't call a fix done until I can prove it.

About me

How I like to work

I like problems where almost right isn't good enough: a tax filing, a digital signature, a customer's bill.

Since April 2025 I've worked on billing, e-invoicing and tax systems. I like to understand why something broke before I touch it, keep changes small, and call a job done only when I can show it works.

I prove fixes with evidenceEvery fix is reproduced first and checked afterwards.
I trace problems to the real causeVague errors get traced back to where they really start.
I design for failureThings recover on their own and fail loudly, never silently.
I own things after releaseI watch production and follow every issue to the fix.

Let's build something that adds up.

I'm looking for backend and platform roles. Email is the fastest way to reach me, and I'm happy to walk through any project in detail.
