Online: 2025 Tech Conferences

DeveloperWeek
Online and in-person
February 11 – 13

DeveloperWeek is one of the most popular tech conferences in the country. This two-day event is for software developers, development teams, managers, and industry leaders. While you can attend the conference in person in the San Francisco Bay area, it’s also available online. This year’s agenda includes a hackathon, workshops, conference speakers, and networking opportunities.

International JavaScript Conference
Online and in-person
May 12 – 15

JavaScript is one of the most popular coding languages in the world. This conference, hosted in London but available to online attendees, covers frameworks, performance, and best practices for coding with JavaScript. If you’re involved in building dynamic, interactive web applications (or wish to be), this is an ideal conference for you.

Conf42 Events
Online
February 6, 20, March 20, and more

Conf42 is a conference and event-focused organization that hosts a variety of engaging discussions throughout the year. On February 6th, they’ll cover Python; on the 20th, they’ll cover Chaos Engineering; on March 20th, they’ll cover Large Language Models (LLMs), and the list goes on in 2025. By subscribing to the Conf42 platform, users get access to live online events, podcasts, and more.

The Chaos Engineering event is particularly interesting. Chaos engineering is the practice of intentionally placing faults into a system to test its resiliency. The goal is to identify potential weaknesses and correct issues before the system is active. This one-day event focuses on practical chaos engineering strategies and helps build systems that thrive under any condition.

Women in Tech Conference
Online and in-person
Various satellite locations
May 20 – 22

The hybrid conference attracts women in tech, underrepresented groups, and allies from around the world with an interactive platform featuring live educational and training content, keynotes, panels, workshops, and networking.

In-Person: 2025 Tech Conferences

PyCon US
Pittsburgh, PA
May 14 -22

As a current or aspiring software engineer, you might use Python as a tool in your day-to-day work and learning. It’s used to build websites, create software, automate tasks, and perform data analysis, and it’s among the most popular languages in the world. Python users who want to interact with other professionals and build their Python knowledge should consider PyCon US, hosted in Pittsburgh, PA. This is a long event, with nine days of tutorials, presentations, conferences, and a job fair.

LeadDev
New York City
October 15 -16

This is a great event for tech managers, leaders, and entrepreneurs. It’s also useful for beginner coders who want to learn more about the industry and someday become a leader in the field. While other conferences have workshops that dive into the fine details of programming, this conference takes a larger view. Speakers and workshops focus on issues like creating a more effective coding team or managing techniques to generate creativity.

React Miami
Miami, FL
April 17 – 18

If you want an early spring escape to sunny southern Florida, all while building your tech and coding skills, this is an event for you. React Miami features more than 25 talks from tech experts and encourages “next-level networking” through an opening party and other gatherings. This conference is uniquely focused on React, a JavaScript library used to build interfaces and single-page applications. Learning React makes a JavaScript programmer even more efficient and allows for dynamic, fast-paced coding.
