Danijel Kostic Stockholm
I’m Danijel. I work with digital business, technology and AI in Stockholm, and I build things on the side, mostly to find out how they work. This is where those projects live — along with the thinking behind them, and the gravel roads, forests and records that keep the rest in proportion.
Building things. Exploring ideas. Staying curious.

Science-based bike fitting, made usable.
An independent cycling project that turns biomechanics, bike geometry and tyre physics into tools riders can actually use — a guided bike fit, a searchable bike database with fit scores, and a tyre pressure calculator.

03Concept · AI / Autonomous research
An autonomous engine for human curiosity.
An autonomous research agent that would keep a living map of how ideas in AI, technology and science connect — following its own questions, noticing early signals, and showing how the map changes over time.

04Concept
Conversational commerce, grounded in what a store actually knows.
An AI-powered conversational commerce project exploring how intelligent chat can improve product discovery and the customer experience in online stores — grounded in each store's own products and knowledge.
05 Independent experiments
Not demos: each of these works, here, on this site. One good tool beats six unfinished ones.
31 ideas, interests and projects, joined by 52 connections — and 9 threads that walk through them, from the saddle to software.
