Heapcon

The lights dimmed, the first talk began, and just like that Heapcon 2025 Day 1 was in motion. ⚡ ️ What followed was a full day of ideas, learning, and honest conversations. We saw people swap insights between sessions and reconnect with old teammates. The sponsor booths were packed, not just with swag, but with real discussions and problem-solving. It was a day fueled by curiosity, generosity, and a shared love for building better things. And that was only Day 1. 💚 #heapcon2025 #heapspace #techconference #devcommunity

Year after year, Heapcon brings us together, and each time we leave amazed by this community and how curious, connected, and full of energy it is. It’s not just the talks that matter. It’s the little moments like the hallway conversations that spark new ideas, the coffee breaks that turn into collaborations, the quiet corners where someone finds exactly the connection they needed. Our sponsors, with their genuine passion for technology and community, make these experiences richer and more meaningful. But it’s the attendees who truly light up the space with their questions, stories, and willingness to share. And behind the scenes, our volunteers and organizers make sure these moments can happen, often quietly, often without anyone noticing. Heapcon 2025 may be over, but the energy stays with us. Thank you to everyone who came, contributed, and made this community stronger. Can’t wait to see what stories we create together next. 🚀 #heapcon2025 #techcommunity #heapspace #techevent

“Did you get enough sleep?” Usually the first question we ask each other on the second day of the conference. 😄 What happens next depends on who’s asking. Guests exchange notes on which talks they’re heading to next and when they’ll have time to catch up, while we go over the plan with volunteers, making sure everything runs smoothly. And that’s how we start a new Heapcon day. Some Heapspacers like to say that people come to conferences more for the people than for the talks. “I ran into a college friend, we haven’t seen each other in years!” “My former teammate is here!!!” “For me, Heapcon feels like a high school reunion.” "I didn’t attend many talks, I spent most of the time talking. That’s why I came." We hear that every year. And maybe that’s what it’s all about. Catching up with your old friends and finding someone new. Talks are that little extra? What do you think? :D

Over the past year, we’ve organized two meetups with Nordeus focused on management topics. Last year, the first one explored “Managing High-Performing Engineering Teams: How Superstars Make or Break the Team.” Our audience clearly loves these discussions on leadership and team management so it was only natural to continue the conversation at Heapcon. At Heapcon, the panel “𝗠𝗮𝗻𝗮𝗴𝗶𝗻𝗴 𝗛𝗶𝗴𝗵-𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗶𝗻𝗴 𝗧𝗲𝗮𝗺𝘀: 𝗕𝗮𝗹𝗮𝗻𝗰𝗶𝗻𝗴 𝗖𝗮𝗿𝗲𝗲𝗿 𝗚𝗿𝗼𝘄𝘁𝗵 𝘄𝗶𝘁𝗵 𝗕𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗥𝗲𝘀𝘂𝗹𝘁𝘀” explored what it takes to build and lead high-performing engineering teams in times of growth, from balancing individual career development with business goals. Engineering Managers shared their experiences on how to achieve results without losing sight of people. 𝗞𝗲𝘆 𝘁𝗮𝗸𝗲𝗮𝘄𝗮𝘆𝘀: - Give direction, not GPS. People should feel comfortable navigating on their own. - Face-to-face time builds trust faster. Even gaming together helps understand people. - Culture matters, it must exist and be refreshed constantly. - Too many stars can hurt performance. Balance beats brilliance. - Accountability culture is the most important. Sometimes the structure needs to change if the team isn’t working well. - Deliver negative feedback in private, positive in the way people prefer. - Capability means learning, practicing, and polishing skills. - Managers should create opportunities, but individuals should also find them for themselves. - Teach people how to learn. It builds efficiency and trust. - Feedback should come from care, be timely, and show what good looks like - Don’t chase the old vibes. Understand when your team enters a new phase and adapt - Give ownership. Make new people feel the product is theirs - Show vulnerability to your team. You don’t need to know it all Well, that’s enough for a LinkedIn post. For the rest, you’ll have to wait until the video is up on YouTube. ;)

Oh, another thing we never change — Dejan Bosanac. At some point, you just stop counting and let yourself be carried away. Because, as we said before, good things shouldn’t be changed. :) Over the years, Bosanac has covered a wide range of topics, always bringing something exciting to the stage. This year, he spoke about “𝗔𝗹𝗹 𝘆𝗼𝘂 𝘄𝗮𝗻𝘁𝗲𝗱 𝘁𝗼 𝗸𝗻𝗼𝘄 𝗮𝗯𝗼𝘂𝘁 𝘀𝗼𝗳𝘁𝘄𝗮𝗿𝗲 𝘃𝘂𝗹𝗻𝗲𝗿𝗮𝗯𝗶𝗹𝗶𝘁𝗶𝗲𝘀 𝗯𝘂𝘁 𝘄𝗲𝗿𝗲 𝘁𝗼𝗼 𝗯𝘂𝘀𝘆 𝘁𝗼 𝗹𝗼𝗼𝗸 𝗶𝗻𝘁𝗼". Vulnerability discovery is one of the crucial aspects of software supply chain security. During the session, he explored which components in our software projects are affected by certain vulnerabilities, whether they are exploitable, and how severe the exploits could be. Participants got a behind-the-scenes look at software vulnerability management, where the data comes from, the formats in which it is exchanged, and how to use it effectively. We hope you enjoyed the talk! :) Until next year!

They say you shouldn’t change a good thing, and we couldn’t agree more. That’s why we’re sticking with the amazing dRumble band for the second year in a row, as well as Ties van de Ven for the fourth. 🙂 The theater is very dark, and the day has just begun. Heapcon attendees have just finished their morning coffee and decided to join us at Madlenianum. So we thought - let’s wake them up with a rhythm they won’t forget. The dRumble ensemble was founded in 2016 by Aleksandar Radulović, a timpanist with the Belgrade Philharmonic, out of a desire to bring something fresh and unseen to the percussion scene. The group is made up of academically trained musicians who decided to play on everything but traditional percussion instruments. dRumble is known for turning everyday waste into extraordinary music: cans, pipes, plastic and metal barrels, computers, bits of tech junk. Anything that can make a sound has become their trademark. Their sound pushes the boundaries between improvisation, performance, and pure adrenaline. Every show is a mix of groove, energy, and chaos that somehow makes perfect sense. They’ve set a new standard for percussion performance while inspiring younger musicians to explore, take risks, and play beyond the limits of what’s considered “allowed.” Because rhythm isn’t about the gear, it’s about attitude. And that attitude makes dRumble one of the most exciting acts on the local scene. Over the past six months, they’ve been working hard on a new project that blends percussion with a dance-techno vibe. At Heapcon 2025, they premiered a piece written especially for this moment, a perfect blend of percussion and dance-techno sound. Sound has never been neglected — though the same can’t always be said for their social media. 😄 With a burst of rhythm and energy, we’re opening the 10th anniversary edition of Heapcon. Once known as VoxxedDays Belgrade, and now proudly Heapcon, officially began! 🚀
