Time flies, doesn't it?
My programming journey began in 2012, with my very first C++ internship. Frankly, I had absolutely no idea what I was doing (this hasn't really changed). Nevertheless, I've picked up some lessons along the way.
Disclaimer: There isn't going to be any code whatsoever in this post.
Or whatever you use to communicate with other people at work.
Programming is a team sport. On rare occasions you might see a brilliant product built from scratch by a single person (CodeSandbox is a great example, although Ives has hired a couple of folks lately) but in the vast majority of cases - you need a team.
Communication skills can make or break a project. Don't worry, it's just you and your team, NASA is struggling with that as well.
Soft Professional skills can be more important to a project success than purely technical ones. Who cares if you hire 5 of the best database experts in the world if they refuse to talk to each other and you end up with 5 different instances of MySQL, Aurora and MongoDB.
Most people are happier when they have a sense of purpose. This applies to work as well.
Your goal is to solve problems with code.
If you have a deep understanding of the system you're building/maintaining then you can make decisions outside of pure tech. Is this feature even necessary? What problem does it solve? Can we solve this problem any other way? Do we want to solve this problem in the first place?
This line of thinking is sometimes referred to as business context, but if you want to do your job well, you should not only understand the context, but to be able to shape and influence that. You don't have to have a C-level position in your organisation to influence your product. Or at least - to understand it.
Oh boy. Code review.
We really don't think about it but the act of putting our work out there in public and have it reviewed by multiple other people is a bit unique to our profession. No wonder people can be anxious about the whole experience.
I have personally seen people submitting code reviews when X wasn't in the office, or Y was at a business trip. X was a brilliant programmer but enduring through his code review process was a chore. If you leave 50 nitpicky (is that a word?), unkind comments under a PR of someone who is a junior programmer, you are not proving your superiority as a developer. You are proving that you're not a good human being.
Okay, but what do I do when I see that this feature is completely broken?
Stand up. Reach out to that person in private. Talk to them, find out why they implemented that code this way.
Most people do not want to write bad code. And if they do, they probably are dealing with constraints you're not aware of. They could also not be really good at programming (yet) and it's your opportunity to shine as a mentor.
According to wikipedia:
Murphy's law is an adage or epigram that is typically stated as: "Anything that can go wrong will go wrong".
It's one of those things that are too true. Always assume that something may break when designing a system.
If you're building a login form, assume that people will copy&paste an entire book into the password field.
If you're building a WYSIWYG window, assume that someone will try to break it, and they are likely to succeed.
If you have a database, it will go down at some point. If you haven't tested recovering your database from a backup, it's not a backup.
If you're doing a live demo in front of an audience - make sure that the demo works online, offline, upside down and under water.
The best part of having a senior next to my job title is that I can finally respond to a question saying:
I don't know, never tried that. I'll take a look and I'll get back to you.
When I was a junior, I was terrified of someone figuring out that I'm a fraud. After a couple of years as a developer - if I haven't seen something, it could be that it wasn't relevant till now. Or I just have another cool piece of tech to learn. Lifelong learning is not a buzzphrase in software development, it's the reality.
Or I'm just an incredible fraudster, managing to fool all those people that I can actually do my job. You never know.
Once you go from "I don't know" to "Okay, that was interesting" - share that with someone. Write a blogpost, record a video, do a talk at a company knowledge sharing event or just ... tell someone. If you think that something is obvious to everyone, it's not. Even the most senior people have something to learn from beginners and vice versa.
Teaching is an incredible way of ensuring that you really understand the subject in question.
As the saying goes:
When one teaches, two learn - someone hella smart
What are your lessons learned as a developer?
