A few spelling errors if you'd like to fix 'em:
"I'm Vinh, a husband, father & programming enthusiast"
"I was lucky to have such a wife."
If you'd like, I can just rewrite the entire page for you.
Your NotyIM service is interesting. I'm building something similar at my current employer.
All the GitHub links on NotyIM's site are broken. Invalid cert at yeo.space, I'm sure you were aware.
Yes, I didn't have time to get to the cert automation yet :D. I promised to myself to do that this weekend.
And thank you so much :).
