This is a submission for the 2026 WeCoded Challenge: Echoes of Experience
One Sentence From My Senior Engineer Changed How I Think About Software
When I first started working as a developer, my knowledge was everywhere.
Some notes were in notebooks.
Some were in sticky notes.
Some were in screenshots.
Some were buried inside ChatGPT conversations.
And when I needed to remember how something worked… I had to search through chaos.
At the time, I thought this was normal. I was learning fast, solving problems, writing code, fixing bugs. I believed the important part was simply getting things to work.
Then one small comment from my senior engineer changed how I think about development.
The Moment I Realized Something Was Missing
One day my senior reviewed how I tracked development information and said something simple:
“Your notes are scattered.”
It wasn’t criticism in a harsh way. It was more like an observation from someone who had spent 20 years designing systems and architectures.
I started paying attention to how she worked.
Everything she did had structure.
Documentation.
Functional specifications.
Technical notes.
System flow explanations.
When she needed to revisit something months later, she didn’t search randomly.
She knew exactly where the information lived.
That moment made me realize something important.
Being a developer is not just about writing code.
It’s about building systems that your future self and your team can understand.
Learning to Think Like an Engineer
As a junior developer, most of my energy went into solving immediate problems:
• Why is this API failing?
• Why is the database returning this value?
• Why is this UI component breaking?
But experienced engineers think differently.
They think about:
• traceability
• documentation
• architecture decisions
• long-term maintainability
I started reorganizing everything.
Instead of scattered notes, I began structuring information by:
Development tasks
System flows
Backend services
Frontend behaviors
Database logic
Even ideas from debugging sessions or conversations with colleagues were captured and categorized.
Slowly, things started to change.
When I returned to a problem weeks later, I could understand it immediately.
A Quiet Skill Many Developers Ignore
Something I noticed while working in tech is that documentation is often underestimated.
Many developers focus only on writing code.
But good documentation does something powerful.
It turns knowledge into something shareable and reusable.
It helps teammates understand decisions.
It helps future developers maintain systems.
And most importantly, it helps you grow faster, because you can see patterns in your own learning.
What This Means for Underrepresented Developers
For many of us entering tech without traditional guidance, we often learn through trial and error.
We pick up skills piece by piece.
But mentorship — even small moments of guidance — can change everything.
One sentence from a senior engineer made me rethink how I approach my entire workflow.
Not because she gave a lecture.
But because she demonstrated what experience looks like in practice.
The Lesson I Carry Forward
Today, I still make mistakes.
I still get stuck debugging.
I still ask questions.
But one thing changed permanently.
I no longer see development as just writing code.
I see it as building systems of knowledge.
And sometimes the biggest growth in your career doesn't come from a complex algorithm or a new framework.
Sometimes it comes from a simple moment when someone more experienced quietly shows you a better way to think.
And you decide to learn from it.
If you're early in your developer journey, here's something I wish someone told me earlier:
Write code, yes.
But also write down why the code exists.
Your future self will thank you.

That's why I often imitate how companies submit their PR's in my solo projects. The reason is for documentation. You also nailed it right. Every time I forgot how to do something I know I've already done in the past, I can simply look up my PR's and commit messages to guide me again. It helps a lot and saves me time.
That’s such a good approach. I’ve started realizing the same thing recently.
Treating PRs and commit messages as documentation really helps “future me” a lot 😄 Especially when revisiting logic I haven’t touched in a while, it saves so much time compared to re-understanding everything from scratch.
Excellent, this is one of the most overlooked or under appreciated skills in development. It can help onboard new team members, and get them up to speed with the code base no matter their level of experience. What type of systems do you use? (e.g., GitHub, Confluence, Obsidian, AppFlowy, Google Docs, etc..)
Totally agree. it’s one of those skills that doesn’t look “technical” at first but makes a huge difference for team productivity and onboarding.
In our team, we mainly rely on Confluence and SharePoint for structured documentation, while code and workflow are managed through Bitbucket.
For my personal workflow, I keep things a bit more flexible, I use Google Keep for quick notes and ideas, and Obsidian when I need to organize deeper understanding (like connecting concepts, flows, or debugging insights).
I’ve found that having both “official” documentation and personal notes really helps especially when trying to understand complex systems faster or explain them to others.
I will recommend Obsidian. I have tried a lot of different ways to do this, but Obsidian just clicked. And when I say 'a lot', I mean a ton.
Thanks for this
This is so relatable.
Just curious what tool you used later on organising your notes? Should help me get the right tool for doing this.
Thank you
Hey! Glad you found it relatable 😊
For our team’s official documentation, we mainly use SharePoint and Confluence, and we manage workflows/code via Bitbucket.
But for my personal notes, I keep it simple. I use Google Keep for quick thoughts and daily stuff.
When things get more complex or structured, I’ve started using Obsidian (someone recommended it here actually 😄), and I really like it. It gives a much clearer structure, especially when linking ideas together and organizing bigger concepts.
I think it depends on your style, quick capture vs deeper thinking. I kind of use both depending on the situation 👍
The story and the information it contains are very useful.
Thank youuuu
Loved this, thank you!
heheh thank youuu. I followed u btw. love your post & project
