    Jana Kurtić, Agile Coach u Bosch-u. Jana je generalista u glavi, agilista u srcu. Posle raznih ,,ekskurzija" iz oblasti digitalnog marketinga, HR-a, razvoja softvera i preduzetništva, svoje mesto pronalazi u Agilnoj metodologiji, sa fokusom na razvoj agilnog načina razmišljanja i implementaciju agilnih metodologija. Ipak, njen krajnji cilj je specifičan: želi da osnaži timove i organizacije do te mere da njena uloga postane suvišna.

    Teme:

    1. Agilnost kreirana oko ljudi, ne oko JIRA tiketa
    2. Sprint je mrtav. Kako da prilagodimo način rada potrebama tima/biznisa?
    3. Flow vs. Friction: Šta nas zapravo koči u procesu rada?

    Teme:

    1. AI u svakodnevnom radu
    2. AI i kreativnost - inspiracija ili prečica?
    3. AI Agenti — šta su i zašto svi o njima pričaju

    Kako je zamišljen Unconference?

    Unconference događaj je osmišljen tako da su gosti aktivni učesnici u diskusiji.
    Umesto predavača koji pričaju dok vi slušate, imamo moderatore koji predlažu nekoliko tema, a vi glasate za one koje vas najviše zanimaju.

    Teme koje dobiju najviše glasova obrađuju se u manjim grupama koje su podeljene u različite prostorije. Ukoliko vreme i raspoloženje grupe dozvole, može biti obrađeno i više tema od jednog moderatora, a očekivano trajanje unconferenca je 60-90min.
    Možete da menjate grupe i moderatore između tema, da uskočite gde god vam je razgovor zanimljiviji. Ideja je da svi zajedno delimo iskustva, razmenjujemo ideje i čujemo različite perspektive.

    Vidimo se!

    Mutation Testing in the Age of AI-Generated Code

    100% test coverage doesn’t mean your code is safe.

    Join us on April 23 at 19h at the Startit Center for a talk “Mutation Testing in the Age of AI-Generated Code” by Dmitrii Suroviagin, Lead Software Engineer at EPAM, one of Heapspace’s partner companies.

    Doors open at 18:30. Talk starts at 19:00.
    *Please note that this event is in English!
    ----------
    Mutation Testing in the Age of AI-Generated Code
    speaker: Dmitrii Suroviagin, Lead Software Engineer @EPAM

    Most teams track code coverage. Some even celebrate 100%.
    But coverage only tells you which lines were executed, not whether your tests would catch a real bug.

    Mutation testing flips the perspective. Instead of measuring how much code runs, it intentionally introduces small faults into your code and checks whether your tests detect them. If they don’t, your test suite may be weaker than it looks.

    In this talk, I’ll start with a short, practical introduction to mutation testing and why it matters. Then we’ll look at how to apply it in JavaScript and TypeScript projects using modern tooling. I’ll share real-world lessons from running mutation testing in production libraries — including performance challenges, CI strategies, and how to avoid turning it into an expensive vanity metric.

    Finally, we’ll discuss why mutation testing becomes even more important in the era of AI-assisted development. When AI agents generate code and tests for us, how do we know they are actually robust? Mutation testing might be the missing feedback loop.
