> port it in less than one day

There's confidence and there's barking mad delusion.

Here's the reality.

I once ported 50k loc from Java to Go. Here are details: https://blog.kowalczyk.info/article/19f2fe97f06a47c3b1f118fd...

Java => Go is easier than JavaScript => Go because languages are more similar. That was a very line-by-line port.

Because I was paid by hour I took detailed notes.

I spent 601 hours to port it.

50k / 601 = 83 lines ported per hour, 665 per 8 hour day, but really 500 per 6 working hours a day. No one does sustained 8 hours of writing code daily.

I would consider that very fast and yet order of magnitude slower than your 5.5 k per day.

10x is not a mis-estimation, it's a full blown delusion.
