fellow from the team was asked to do the estimate by manager - he said 2 weeks

then manager asked what if we add one more developer - he said, again 2 weeks and maybe add day or two

I was asked same question without knowing that they already asked fellow from the team same question - I said around two weeks, maybe day or two more! XD

as manager was confused and not satisfied with the estimates, goes to our team leader with the same questions - team leader said - 2 and half weeks and if you add one more dev to it, 3 weeks minimum

we didn't know that all of us were asked as manager did that behind our backs, in the end manager learned lesson in greed as we got to stick to team leaders estimate!

also that was very rude of underestimating someone's ability, same manager did had personal bias and frequently mocked us, for example when we said that that we will implement ML for cropping images at the right place (ie. crop part of the image where the face is) on the backend. Response was something like: 'You guys will do the ML? Are you shitting me? You're not /insert FANG company/!'

best team win ever!

second best team win ever is when whole team left the company in matter of weeks

When I saw the U-Boot prompt on the console of a system that we'd developed from scratch all from openly available documentation. When the board was fabricated and brought in for software bring up, it was basically less useful than a brick. It felt awesome giving life to it. We had to configure it and calibrate it. It's extra challenging when you have a lot of analog circuits. Yeah so we didn't win 'against' anyone but that victory stands for itself.

A certain team member left the team

So we're seating in our small dev room where nothing else and no one else can fit in. I'm sitting next to the door so whenever anyone want to get in or out I need to do it first.
It's middle of the day and one of our dev friends. You don't believe what he did.
He fixed bug. So I pushed the red button to signalise that the bug was fixed and at the same time the alarm siren has launched and red lights starts to blink. Next minute couple of strippers wants to enter. Since the room is small they started dancing on our desks. Waitress opens champagne that's pouring on my leg and then I woke up and my dog is pissing on me.

Our project won in a competition organised by my uni

There is no such thing

If a team of two counts, did some hackthebox challenges, wrote some funny scripts, found a way to using nodejs as an attack vector.
Fun

Best dev team win like in a cage fight against managers or something?

Me, myself and I. Dream team

Team Lunch is the best Team Win. Nothing on the project so far
