Prompts to Predictable UIs & The evolution of the Rows Grid system - FE.OPO #9

The year is just getting started, and so are we... Join us for our first meetup of the year at Rows for a magical evening of coding and networking!

👋 Join us at the Rows for the Frontend Meetup in Porto to discuss fun things around the web development world, grab a beer, and make some nice connections.
RSVP now in Meetup! Otherwise, you may be stuck on the waitlist 👻

## Schedule:

18:30 - Doors Open

19:00 - Short message from the organizers and welcome to the Frontend.OPO community

19:05 - Welcome from our hosts - Rows

19:10 - From Prompts to Predictable UIs
AI generated UIs are naturally unpredictable. This talk demonstrates practical techniques for turning coding agents into predictable UI builders through feedback loops, MCP servers, skills, and libraries.

Guilherme de Andrade – Senior Frontend Engineer

19:45 - The evolution of the Rows grid system
A deep dive into our transition from a single spreadsheet per screen to a dashboard of multiple interactive elements. We’ll walk through the development strategies and architectural shifts required to scale our spreadsheet product. This will cover subtopics ranging from low-level decisions like our packaging systems to the "nitty-gritty" of virtualizing thousands of cells without compromising on scroll UX.

Hermen Isaias – Lead Software Engineer at Rows
Bruno Pinto – Frontend Lead at Rows

20:15 - Networking
Note: All times in the schedule are an approximation.
