I Built My Very Own Password Manager https://t.co/njAdazCgLu via @YouTube

[Sparsh Jain @SplinterSword1]

I rebuilt a password manager — this time with the goal of creating something people could realistically trust, not just a demo.
Biggest lesson:
Auth is just the door, sessions and key management are the real security model.
Built with client-side encryption

Good engineering isn’t always about making a feature work.

It’s also about understanding:

Performance, scaling impact of your code and how it is going to affect your users in the long run.

[Sparsh Jain @SplinterSword1]

I recently worked on a PR to add curve support for custom shapes in a graph editor (Meshery/Kanvas) that uses Cytoscape.js.

What started as a feature quickly turned into a deep lesson on performance, rendering, and knowing when not to ship. 👇

[Sparsh Jain @SplinterSword1]

The realization:

Supporting curves by converting them into polygons is technically correct — but performance-hostile in Canvas-based graph engines.

This becomes a foot-gun when exposed to users.
