Full-stack developer · Zagreb · 5+ years
Curiospective turns a messy set of options into one clear, well-built solution — web apps, APIs and mobile apps that ship and keep running. Word origin“Perspective” comes from the Latin perspicere — to look through. Which is exactly what a lens is for.
Your problem → my part FactEach eye has a blind spot where the optic nerve leaves it. You don’t see a hole — your brain quietly fills it in.

Projects I helped build

Built compliance-automation and report-builder features in the Rails platform, used by clients in 10+ countries.
An all-in-one agency management platform — projects, time tracking, budgets and billing — used by agencies and consultancies to run a profitable business.
Worked on the invoicing team: features for generating and managing invoices and automating billing, so finance teams spend less time on manual work.

How I work — a small puzzle
Every project starts as a knot. Your turn: grab the options A–E and move them until no lines cross. Every knot you put in its place reveals a little more about how I work.
Questions first. Who is it for, what already exists, what is actually needed — every idea gets a line.
Weigh the real options and move each one to where it belongs until nothing crosses. That’s most of the work.
Commit to the one that fits, build it properly and ship it to production — then keep it running.
About
I'm Ivan, a full-stack developer from Zagreb with 5+ years of production software behind me — across fintech, logistics, compliance automation and field-operations SaaS. Curiospective is how I work independently with teams who want clean code and clear thinking. HistoryAround 1415 in Florence, Brunelleschi used a painted panel, a peephole and a mirror to demonstrate linear perspective — and changed how we draw space.
Off the keyboard: semi-professional jiu jitsu athlete, happiest outdoors, and always up for a game — or a good problem to chew on.

How we can work together FactYour eyes jump around three times every second. Your brain edits out the blur, so you never notice.
A clear scope, timeline and price agreed before we start. Best for new products, MVPs and well-defined features.
Hourly or a monthly retainer for teams that need a dependable developer on their product for the long run.
