Open Source Contributions
shadcn/ui
I created a PR to the shadcn/ui repo that added a new components registry to the ecosystem (lmscn). This is a components registry for interactive learning components you can drop into your LMS app in minutes. This was my first contribution to a major OSS project and taught me a lot about the open-source community.
MikroORM
I create a PR to the MikroORM repo that fixed a crash in SchemaComparator.hasSameDefaultValue when a column's to.default is a non-string value. The method coerces from.default defensively (from.default.toString().toLowerCase()) but calls .toLowerCase() directly on to.default at the two === 'null' guards. When to.default is a number or boolean (a column whose entity default is @Property({ default: 0 }) or @Property({ default: true })), it throws: TypeError: to.default.toLowerCase is not a function. This was a simple but critical two-line fix that I was able to contribute to the MikroORM repo.
Open Mercato
I create a bug report issue to the Open Mercato repo that describes a security finding in the integrations API route. The issue describes a pattern that warrants security attention beyond a simple UI bug. The issue was closed by the maintainer and was folded in the next release.
