It has been almost 3 months solid I didn't do any major changes to my Full-stack development endeavor. But luckily, I'm still able to tweak a thing or two here and there on my Portfolio V4 that should be live now. Unfortunately, there are some problem arises in production mode. In development mode (before doing npm run build), everything works just fine. I've tested a bunch of ways to tackle this problem of mine. But till now, no avail. Right now, I'm prioritizing learning the authentication process again. Hopefully, this newest portfolio version 4, could be published before mid of this year.
