Worst thing you've seen another dev do? Here is another.

Early into our eCommerce venture, we experienced the normal growing pains.

Part of the learning process was realizing in web development, you should only access data resources on an as-needed basis.

One business object on it's creation would populate db lookups, initialize business rule engines (calling the db), etc.

Initially, this design was fine, no one noticed anything until business started to grow and started to cause problems in other systems (classic scaling problems)

VP wanted a review of the code and recommendations before throwing hardware at the problem (which they already started to do).

Over a month, I started making some aggressive changes by streamlining SQL, moving initialization, and refactoring like a mad man.

Over all page loads were not really affected, but the back-end resources were almost back to pre-eCommerce levels.

The main web developer at the time was not amused and fought my changes as much as she could.

Couple months later the CEO was speaking to everyone about his experience at a trade show when another CEO was complementing him on the changes to our web site.
The site was must faster, pages loaded without any glitches, checkout actually worked the first time, etc.
CEO wanted to thank everyone involved etc..and so on.

About a week later the VP handed out 'Thank You' certificates for the entire web team (only 4 at the time, I was on another team). I was noticeably excluded (not that I cared about a stupid piece of paper, but they also got a pizza lunch...I was much more pissed about that). My boss went to find out what was going on.

MyBoss: "Well, turned out 'Sally' did make all the web site performance improvements."
Me: "Where have you been the past 3 months? 'Sally' is the one who fought all my improvements. All my improvements are still in the production code."
MyBoss: "I'm just the messenger. What would you like me to do? I can buy you a pizza if you want. The team already reviewed the code and they are the ones who gave her the credit."
Me: "That's crap. My comments are all over that code base. I put my initials, date, what I did, why, and what was improved. I put the actual performance improvement numbers in the code!"
MyBoss: "Yea? Weird. That is what 'Tom' said why 'Sally' was put in for a promotion. For her due diligence for documenting the improvements."
Me:"What!? No. Look...lets look at the code"

Open up the file...there it was...*her* initials...the date, what changed, performance improvement numbers, etc.

WTF!

I opened version control and saw that she made one change, the day *after* the CEO thanked everyone and replaced my initials with hers.

She knew the other devs would only look at the current code to see who made the improvements (not bother to look at the code-differences)

MyBoss: "Wow...that's dirty. Best to move on and forget about it. Let them have their little party. Let us grown ups keeping doing the important things."

Does most memorable in a bad way count? 🤔

He left almost 2 years ago..or even more.. left a bunch of bugs and logical fuckups for me to fix.. some already fixed, some still lingering there..

I want to not blame him for everything, since we lack proper code review protocols and all.. but I've asked on several occasions if he understands the problem and what must be done..and the answer was always yes..results, after I got time to check up on him, the code he wrote was most probably copy pasted from stack overflow or somewhere else.. butchered in any and every way possible..

And of course already checked in to TFS.. along with bunch of files that were not even changed (he didn't bother to check that and exclude them) + a bunch of files from other projects... Told him to not do that on several occasions too, but he still managed to fuck things up this way.. leaving all the uncommented debugger; crap and alerts in the js files..

On one occasion I was working on new GUI..api part I already finished..got the order from above to delegate this to him as it is not much he can fuck up so I could focus on more important & complex stuff..
Maybe additional 4h of work + testing for everything..
I show him the prepared files, one controller, one view..explained what parts of code goes where etc.. a little short of writing everything myself.. Ask if he understands what needs to be done & how and told him if he has any problems/questions to ask me asap..
Said he understood what needs to be done.. after a day or two he asks me why something is not workig as expected.. I check the files, correct initialization was commented out and all the code was stuffed in the view file.. Took him another day to move the code to proper files.. Not sure about the possible bugs left there as the client later decided that they will not be using this..

I later found out that years of C# experience on his CV was actually a school course.. he didn't even know why the changes on api are not showing up..because he didn't know that he has to build the code..

I mean, if he was honest when asked about experience with .net, we would've taken a month or two to just explain everything from the start..

But as he didn't and based on his CV (much more experience with .net than me) and 'I understand everything' attitude from the start I assumed he knows WTF was he doing..

Boy was I wrong..

He was also more interested in how much I get payed and if I have a company phone etc..than actually doing his job.. I fucking hate chit chat, and this..well.. he didn't get the hints that this is in no way appropriate to ask.. I've told him that if he has problems with his pay and bonuses that he should talk to the management and not me about this..and that I'm only interested in his actual work and progress..

So yeah, I'll definitely be remembering this guy till the day I die..

I don't understand how my managers suddenly forgot that my "down weeks" we're due to technical debt I inherited. The whole on boarding hasn't been in my favor. I've stayed at work everyday til long after work hours, digging through code, trying to get JIRA tickets done, encountering issues specific to our code base that no one would ever discover on their own without docs/help from the original dev. The whole time, I was told that they know what's going on and apologize. I constantly expressed that plenty of what we were doing was building on antipatterns. They acknowledged. When a ticket wasn't done, they always knew the very specific reason and I wasn't faulted. 6 months in, I receive a great annual review. 7 months in? I receive an email titled "Performance Discussion," detailing 4 of those incidents where a ticket was pushed back -- with inaccurate depictions of what actually went down. They actually wrote that I didn't communicate. One part of the report expressed that there were "bugs found in production due to inadequate test coverage." WTF!! Everything made it past code review and QA. What are you talking about?? In fact, the person who wrote that merged my code in each time!!!! Insane!! Anyway, Q2 is partly about cleaning up technical debt, which is a responsibility I have been vested (fantastic). I've deleted about 800 lines of code in the last 2 weeks and added plenty of doc strings. Two of the most important modules our application works from are about 1000 lines of JavaScript each without any comments/docs. I'm changing that, but I don't know if my managers truly know the significance. Someone was recently promoted to my position but manually wrote out a sorting algorithm (specified numeric indexes and all); didn't do shit to earn it but breathe. And while they get more and more praise and responsibility, I'm over here stuck trying to prove myself and live up to why I assume they hired me. It's ridiculous. I love the company, but I'm not getting any sleep and I'm stressed out. It's only been about 7 months and I've been doing everything I can. Why is this happening? What am I doing wrong? I've been developing a recurring (physical) headache and ticks. My heart/chest area sometimes feels like it's lifting weights. I sound like an idiot, pushing so hard for a company that isn't mine, but I take so much pride in being in this position, and I'm so set on proving myself this early in my career (I'm 25).

Made a mistake in scrapping project, realized it AFTER it spent 3 days running, now I relaunched it (corrected) with 4 times more workers to meet the deadline

I can't help it sounding bitter..
If you work some amount of time in tech it's unavoidable that you automatically pick up skills that help you to deal with a lot of shit. Some stuff you pick up is useful beyond those problems that shouldn't even exist in the first place but lots of things you pick up over time are about fixing or at least somehow dealing or enduring stuff that shouldn't be like that in the first place.
Fine. Let's be honest, it's just reality that this is quite helpful.

But why are there, especially in the frontend, so many devs, that confuse this with progress or actual advancement in their craft. It's not. It's something that's probably useful but you get that for free once you manage to somehow get into the industry. Those skills accumulate over time, no matter what, as long as you manage to somehow constantly keep a job.
But improving in the craft you chose isn't about somehow being able to deal with things despite everything. That's fine but I feel like the huge costs of keeping things going despite some all the atrocities that arose form not even considering there could be anything to improve on as soon as your code runs. If you receive critic in a code review, the first thing coming back is some lame excuse or even a counter attack, when you just should say thank you and if you don't agree at all, maybe you need to invest more time to understand and if there's some critic that's actually not useful or base don wrong assumptions, still keep in mind it's coming from somebody that invested time to read your code gather some thoughts about it and write them down for you review. So be aware of the investment behind every review of your code.
Especially for the frontend getting something to run is a incredibly low bar and not at all where you can tell yourself you did code.
Some hard truth from frontend developer to frontend developer:
Everybody with two months of experience is able to build mostly anything expected on the job. No matter if junior or senior.
So why aren't you looking for ways to find where your code is isn't as good as it could be.

Whatever money you earn on top of your junior colleagues should make you feel obligated to understand that you need to invest time and the necessary humbleness and awareness of your own weaknesses or knowledge gaps.
Looking at code, that compiles, runs and even provides the complete functionality of the user story and still feeling the needs do be stuff you don't know how to do it at the moment.

I feel like we've gotten to a point, where there are so few skilled developer, that have worked at a place that told them certain things matter a lot Whatever makes a Senior a Senior is to a big part about the questions you ask yourself about the code you wrote if if's running without any problems at all.
It's quite easy to implement whatever functionality for everybody across all experience levels but one of your most important responsibilities. Wherever you are considered/payed above junior level, the work that makes you a senior is about learning where you have been wrong looking back at your code matters (like everything).

Sorry but I just didn't finde a way to write this down in a more positive and optimistic manner.

And while it might be easy to think I'm just enjoying to attack (former) colleaues thing that makes me sad the most is that this is not only about us, it's also about the countless juniors, that struggle to get a food in the door.
To me it's not about talent nor do I believe that people wouldn't be able to change.
Sometimes I'm incredibly disappointed in many frontend colleagues. It's not about your skill or anything. It's a matter of having the right attitude.
It's about Looking for things you need to work in (in your code). And investing time while always staying humble enough to learn and iterate on things. It's about looking at you
Ar code and looking for things you didn't solve properly.

Never forget, whenever there's a job listing that's fording those crazy amount of work experience in years, or somebody giving up after repeatedly getting rejected it might also be on the code you write and the attitude that 's keeping you looking for things that show how awesome you are instead of investing work into understanding where you lack certain skills, invest into getting to know about the things you currently don't know yet.
If you, like me, work in a European country and gathered some years of industry experience in your CV you will be payed a good amount of money compared to many hard working professions in other industries. And don't forget, you're also getting payed significantly more than the colleagues that just started at their first job.
No reason to feel guilty but maybe you should feel like forcing yourself to look for whatever aspect of your work is the weakest.

There's so many colleagues, especially in the frontend that just suck while they could be better just by gaining awareness that there code isn't perfect.
