Dhanush P K

Kochi, India Software Engineer · Backend & Infrastructure Résumé ·

I build backend systems for finance.

Payments, lending platforms, and the queues and audit trails they run on.

I am currently at Nav Technologies in Kochi. I work on COLIGO, a multi-tenant lending platform, and on a payment gateway that settles transactions between banks.

Before that I built iOS and web products at Lascade App Studio and on my own.

I studied Computer Science at CUSAT. In my own time I write Go, mostly infrastructure tools for problems I ran into at work.

If you want to talk about backend systems, payments or Go, write to dhanushpk50@gmail.com.
