Below, you’ll find a link to each video along with a summary of the talk. We hope you enjoy and find inspiration in the variety of topics shared!

Developer Productivity & Metrics, presented by Prashant Punjabi:

In the opening talk, Prashant Punjabi explored the complex topic of developer productivity, drawing from an article he authored for the Solution Street newsletter. He opened by highlighting the challenges of measuring productivity effectively, noting that simplistic metrics—like lines of code or number of commits—can be misleading or even counterproductive. Developers may game such metrics, leading to superficial progress while ignoring deeper issues like code quality or maintainability.

Prashant introduced two well-regarded frameworks: the DORA metrics and the SPACE framework. The DORA metrics—developed by Google’s DevOps Research and Assessment group—focus on deployment frequency, lead time for changes, change failure rate, and time to restore service. These are useful for DevOps workflows but only measure productivity from the point of code commit onward. The SPACE framework, created by Microsoft and GitHub researchers, adds a more holistic view by incorporating satisfaction and well-being, performance, activity, communication and collaboration, and efficiency and flow.

He emphasized that developer experience is becoming a key focus in measuring productivity—not just in terms of individual satisfaction or good equipment, but in creating team structures and processes that promote flow, clarity, and quality. As consultants, Prashant encouraged team members to actively improve onboarding materials, share ideas from past experiences, and elevate both their own work and that of the client teams they support.

Crunch Labs Hackpack (Robotics STEM Kits), presented by Ryan Gehl:

Ryan shared his enthusiasm for robotics and STEM education through a presentation on Crunch Labs Hackpack, a subscription-based robotics kit created by YouTube educator and former NASA engineer Mark Rober. Drawing from his own background in robotics—as a graduate student, TA, and mentor—Ryan introduced the Hackpack as an exciting and well-designed entry point for teens and adults interested in hands-on robotics projects. Each box includes detailed instructions and components to build a functional robot, with new kits released monthly.

He highlighted his daughter’s experience with the kits, noting that she completes them independently each month and often shows off the finished projects—many of which are interactive and playful, like the featured card-dealing robot. Ryan demonstrated how the robot identifies players, deals cards for various games like blackjack, and includes basic decision logic. He also gave a brief tour of the Arduino-based code that powers the device, emphasizing how accessible and modifiable it is for beginners and hobbyists alike.

Throughout the talk, Ryan emphasized how tools like Hackpack not only teach coding and electronics, but also inspire creativity and confidence in young learners. He strongly recommended it for anyone with a personal or family interest in STEM, praising both the technical quality of the kits and the broader mission of encouraging hands-on learning.

Regular Expressions 101, presented by Jeff Schuman:

In his talk, Jeff delivered a fast-paced yet accessible primer on regular expressions (regex)—a powerful tool for matching, validating, and manipulating text. He explained that while regex syntax can initially seem intimidating, it becomes an essential and versatile skill once mastered. With examples, he showed how regular expressions can be used to validate user input (like email addresses and zip codes), extract data from logs, and perform complex find-and-replace operations across files or JSON structures.

Jeff walked through common regex syntax and concepts, including character classes (like \d for digits or \w for word characters), anchors (^ for start of string, $ for end), quantifiers (+, *, {n}), and capture groups for extracting and reusing matched data. He demonstrated these ideas in practical contexts using tools like Visual Studio Code and the online regex testing site RegExr, showing how developers can test and refine expressions with live feedback. He also discussed how databases such as PostgreSQL support regex queries, making it a useful skill across the stack.

To wrap up, Jeff encouraged developers to embrace regular expressions not just as a niche tool, but as a core part of their toolkit. He acknowledged that modern AI tools can help generate regex patterns, but reminded the audience that understanding and testing those patterns remains crucial. His message was clear: learning regex pays off in day-to-day development, and it’s well worth the time to build fluency with it.

My Trip to Japan – Tips & Experience, presented by Stephen Charette:

Stephen wrapped up the lightning talks with a personal and practical guide based on his recent trip to Japan during peak cherry blossom season. His presentation blended travel storytelling with helpful tips for anyone considering a similar trip. Starting with logistics, he recommended tools like Skyscanner for affordable flights and Booking.com for accommodations. He highlighted the importance of using Google Maps for navigation—especially for navigating Japan’s extensive train system—and praised Suica card integration in Apple Wallet for seamless subway access.

Stephen detailed his travel route, which started in Tokyo and included stops in Kyoto, Osaka, Himeji, and Kurashiki. He and his group chose a variety of lodging styles—from traditional Japanese homes and modern apartments to hostels and pod hotels—to experience the full cultural range. He also shared insights on common travel challenges, such as Japan’s lack of public trash cans, the need to carry cash and coins, and the value of using luggage forwarding services to avoid carrying bags on crowded trains.

To enhance the travel experience, Stephen recommended a set of useful apps, including language translators like DeepL, restaurant discovery tools like Tabelog, and local convenience tools like Payke for translating product labels. He closed with some lessons learned—like the limits of Duolingo for real-world conversation and the sheer amount of walking involved—and offered to chat with anyone planning a future trip. The talk was both informative and engaging, making international travel feel more approachable and inspiring.

We hope you found this edition of Lightning Talks as engaging and insightful as we did. From developer productivity to travel tips, the range of topics reflected the curiosity, expertise, and creativity that make our company thrive. Thanks to all our speakers for sharing their knowledge!
