GSoC 2026 - Week 6

#devjournal #learning #opensource #performance

Week 6 of my Google Summer of Code journey with CircuitVerse (June 29th to July 5th) was arguably the most rewarding week of the summer so far.

🧠 The Power of Elite Code Review

This week, all my mentors dropped reviews on my initial three pull requests. It was the first time I’ve ever experienced code review at this level of depth, and honestly, I learned a lot from the reviews.

My mentors caught edge cases I hadn’t even considered:

⚡ A brilliant architectural idea: Caching the canonical hashes. Instead of recomputing the heavy Weisfeiler-Leman structure and SHA-256 hash every single time a project saves, we can cache the hash of circuits that haven't changed and reuse them.
💡 This caching suggestion completely shifted how I view the project's performance. It opens the door to fast saving pipelines! We decided to slate this optimisation for a dedicated upcoming PR.

🥞 CircuitVerse GSoC contributors' meeting

During our weekly CircuitVerse GSoC contributors' meeting, I shared my progress but also raised a genuine concern: since almost all of my upcoming PR's relies on my initial pull requests being merged, waiting for slow code reviews was starting to bottleneck my timeline.

My mentor, Aboo, dropped an absolute game-changer of a suggestion: Stacked PRs. If you want to know more about it, you can read https://newsletter.pragmaticengineer.com/p/stacked-diffs

⏳ Timeline Extensions & Midterms

My mentors decided to extend my project timeline by two weeks! 🗓️

It gives us plenty of room to run thorough testing, edge-case debugging, and performance polishing. Because of this timeline adjustment, my official GSoC midterm evaluation has also shifted by a week.

🥳 FINALLY... IT MERGED!

There couldn’t have been a better way to close out the week. On the very last day, I opened GitHub and saw the glorious notification: My first pull request as a GSoC contributor was officially merged into main! 😭🎉
