HELLO FROM SERBIA

Hi, I'm Nikola.

I build useful things for the real world.

Back-end developer, electronics enthusiast and radio amateur. I like software that solves a problem, runs reliably, and feels good to use.

A LITTLE ABOUT WHAT I DO

01 / About

Curiosity, put to work.

God helps — I'm Nikola Dašić: a dad, a programmer, a HAM radio operator, and a guy with way too many hobbies.

Irregular creatine drinker, Prolom water devotee, chicken farmer, proud Dacia owner, IKEA regular, GNU/Linux supporter, electronics technician, Orthodox Christian, gym devotee who ran his first lap around Ada Ciganlija on 17 August 2026, cured-beef connoisseur, Yandex admirer and cycling buddy.

There's more than one side to my work.

Over the years I've worked with teams on projects in automotive, fintech, healthcare, distributed Web3 systems, and more. What follows is just a selection of my own open-source and free projects as an indie developer, not a catalogue of everything I've built at work.

HOME LAB / RADIO

The lab behind the screen.

The wooden cabin in my backyard houses my home lab and amateur radio gear. I run servers there, experiment with electronics, and host some of the things I build. Part workshop, part server room — definitely not a giant cloud.

02 / Work

Things I've built on my own.

A few independent projects, from everyday tools to hardware experiments.

FEATURED PROJECT · HOME COOKING

Kuvajmo.

Home-cooked food from your neighbours, not from an app.

Someone nearby is already cooking dinner. With Kuvajmo they make a few extra portions, neighbours reserve them ahead, chip in toward the cost and pick the food up themselves. No couriers, no commission, no waste. Native iOS and Android apps, and it all runs on my home lab.

FEATURED PROJECT · PERSONAL FINANCE

Troškomir.

A clearer picture of where your money goes.

I built Troškomir to help people track expenses, budgets, cards and savings in one place. It can scan fiscal receipt QR codes, works offline for everyday tracking, and syncs when a connection returns. It runs on my own home server.
