Lemon 🍋

Lemon 🍋

With a lifelong passion for the weirdness of the internet and a day job as a development lead for whoever hired him, Lemon spends his professional time making websites for money and his free time making websites for no money.

He's created a number of stupid things for the internet, like all the games on kinda.fun, the wikiHow guessing game damn.dog, the Google Autocomplete game idiots.win, and a bunch of other things of questionable use. He also hosts a podcast that looks at some of the internet's weirder subcultures. It is not safe for your work, unless you work somewhere really cool.

Pradeep Sharma

Pradeep Sharma

Pradeep is as old as the internet but he didn’t have reliable access to the electricity or the internet until he entered IIT Roorkee where he studied electronics and programming. His interest in programming grew more after his work as a Computer Science Researcher at L3S Research Center (Germany) and Sabanci University (Istanbul). His newfound passion and early successes propelled him into a career as a developer.

Throughout his 14+ years of career, Pradeep developed applications in diverse domains such as dev productivity, privacy, neural search, authentication, NLP, cryptography, data engineering, etc.

Pradeep founded two startups, authored a book, and published #OpenSourceDiscovery newsletter. For 8 years, Pradeep developed and maintained his key project - Developer Diary, a cross-platform productivity tool for developers. This long-term commitment provided him with deep insights into the evolution of various engineering and community functions. Leveraging these insights, he guided various Open Source organizations to create category-leading developer tools and foster thriving, engaged developer communities.

As a late bloomer in tech from a small town, he witnessed how the internet empowered developers from remote areas to transform their lives. This inspired him to found Invide, an invitation-only community for developers from underserved regions. Drawing from his own journey, the initiative helped over 15000 experienced developers with resources he once lacked.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2025

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2025. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
