Hey community! I’m an Advanced Associate Software Engineer at Accenture and just discovered this platform today through Hacktoberfest 2026. I'm always excited to talk about system design, backend architecture, and developer tooling. If you have any favorite repos participating this year or community spaces to follow, feel free to drop them below. Happy hacking!
What Open Source Has Taught Me So Far I started contributing to open source because I wanted to learn how real projects are built outside of tutorials. Over time, I got comfortable working with technologies like React, Node.js, TypeScript, MongoDB, Next.js, and REST APIs. But the biggest learning didn't come from the technologies themselves. It came from reading someone else's code, understanding an existing codebase, opening issues, reviewing pull requests, fixing bugs, and learning how to communicate with other developers.

A user loads a year of minute candles, zooms out to see the whole period, then downloads a CSV. The file should retain the selected resolution even if the chart has to combine candles to draw that view.

Each can make a different decision about how much data it needs. Those decisions should remain visible to the user.
