    #43 Elena Coazzoli (Lingvano): One Codebase, Three Platforms, 4 Million Users - With a Team of Five?

    Season 2 Episode #24: Elena Coazzoli went from studying radiology in Italy to leading product for a 4-million-user sign language learning app with an integrated team of five covering product, engineering, design and data, with no separate departments.We get into why gamification and spaced repetition both failed when tested, what makes sign language fundamentally different to teach through an app, and the discovery that over half of Lingvano's learners can't find anyone to practice with. Elena also shares how AI is shifting what engineers actually focus on, and what working alongside deaf colleagues taught her about accessibility far beyond screens. 🔔 Follow TestDevLab for more technology & software related content: LinkedIn: https://www.linkedin.com/company/testdevlab/ Facebook: https://www.facebook.com/TestDevLab/ Instagram: https://www.instagram.com/testdevlablv/#TechEffect

    #42 Adrián Bolonio (Kununu): No ARIA Is Better Than Bad ARIA - And AI Is Making It Worse

    Season 2 Episode #23: Adrián Bolonio picked accessibility as a conference talk topic almost at random. It became a career-defining commitment that took him from Willhaben to GitHub, where he built the platform's first accessibility settings, to Miro, where he turned a visual canvas into audio with footsteps and trash can sounds.We explore why the same accessibility issues top the WebAim survey every year and nobody fixes them, how to convince leadership to prioritise accessibility under shipping pressure, and why AI is simultaneously helping and hurting the cause. Adrián also shares what it takes to build accessibility into design systems rather than bolt it on, and why no ARIA is always better than bad ARIA.You can learn more about Adrián on his website: https://www.adrianbolonio.com/en 🔔 Follow TestDevLab for more technology & software related content: LinkedIn: https://www.linkedin.com/company/testdevlab/ Facebook: https://www.facebook.com/TestDevLab/ Instagram: https://www.instagram.com/testdevlablv/#TechEffect

    #41 Jan Daniel Sulaiman (1NCE): He Detects Network Outages Before the Operator Even Knows

    Season 2 Episode #22: What happens when a kid whose only goal was to become his dad's boss accidentally falls into IoT through a missing sensor reading? Jan Daniel Sulaiman, VP of Global IoT Solutions at 1NCE, shares how he helped build a global connectivity platform from a single room with fewer than 20 people.We explore what it takes to operate 15 million connections across 175 countries, why 1NCE built custom network probes that detect outages before the local operator does, and how the platform evolved from basic connectivity to device-level awareness. We also dig into where AI is already delivering real value in IoT and the big question Jan is watching: is AI truly transformative like electricity, or will it go through the classic hype cycle like everything else? 🔔 Follow TestDevLab for more technology & software related content: LinkedIn: https://www.linkedin.com/company/testdevlab/ Facebook: https://www.facebook.com/TestDevLab/ Instagram: https://www.instagram.com/testdevlablv/#TechEffect

    #40 Ergo Esken (Microsoft): The Hardware and Science Behind Sounding Good on a Call

    Season 2 Episode #21: What happens when a hi-fi hobbyist who was manufacturing driver's licenses gets a tip from his brother about a new audio lab being built at Skype? Ergo Esken, Principal Software Engineering Manager at Microsoft, shares how that moment launched nearly two decades of ensuring the call quality millions of people take for granted every day.We explore why getting hardware right still matters more than most people realise, how design teams wanting thinner devices force engineers into impossible tradeoffs, and what it actually looks like to test a call using head and torso simulators in anechoic chambers. We also dig into why users blame the platform, not the device, how you write test specs for ML features that behave differently every time, and why algorithms will happily calculate numbers from completely scrambled audio that only a human can catch. 👉 Hit "Follow" on our podcast page to receive updates on future episodes of "Tech Effect," where we bring you the latest news, trends, and expert insights from the world of technology.

    #39 Dennis Thisner (Rebtel): Code First, AI Second - Why Knowing the Basics Matters More Than Ever

    Season 2 Episode #20: Dennis Thisner quit his first job out of pride, called his mom to brag, and realized he had no plan. A friend's tip and some truly terrible bug reports later, he was a QA engineer. Ten years on, he's built quality processes from the ground up across gaming, enterprise SaaS, agency work, and now telecom at Rebtel.We explore what it takes to build QA where none exists, why developer buy-in is the hardest first step, and why he tells his team to code first and use AI second. Dennis also shares where test automation is heading when you can just hand AI your test cases, and why quality has less to do with attention to detail and more to do with the atmosphere around your team.You can check out Dennis's work on his GitHub: https://github.com/dthisner 👉 Hit "Follow" on our podcast page to receive updates on future episodes of "Tech Effect," where we bring you the latest news, trends, and expert insights from the world of technology.

That decision launched a 17-year journey across fintech, insurance, gaming, and cybersecurity, each teaching him something different about quality.
