Starting your career as a software developer can be as exciting as it is daunting. Looking back on my journey, there are things I wish I had known when I was just starting. Here’s a collection of advice, lessons, and resources to help you navigate the early stages of your career and accelerate your growth as a developer.
1. It’s Okay Not to Know Everything
When I started, I felt the pressure to know everything: frameworks, programming languages, tools—you name it. The truth? No one knows it all. The most important skill is knowing how to learn effectively.
Actionable Tips:
- Break problems into smaller, manageable chunks.
- Learn to ask the right questions (Google is your friend, but so are your colleagues).
- Focus on building a strong foundation in core concepts like data structures, algorithms, and clean code principles.

2. Your First Code Won’t Be Perfect, and That’s Fine
As a junior developer, I spent way too much time trying to write "perfect" code. In hindsight, it’s far more important to ship something functional and learn through iteration.
Actionable Tips:
- Focus on writing code that works first, then optimize later.
- Embrace code reviews as learning opportunities, not criticisms.

- Clean Code by Robert C. Martin

- The Importance of Code Reviews: A Guide to Better Software Development (Dev.to)
3. Communication is Key
Technical skills are important, but your ability to communicate and collaborate with your team is just as critical. Learn to explain your thought process clearly, whether you’re in a meeting or writing documentation.
Actionable Tips:
- Practice writing concise, clear commit messages.
- Don't hesitate to ask for clarification when requirements or feedback are unclear.
- Always explain the why behind your decisions during discussions.

4. Learn to Manage Technical Debt Early
In the rush to deliver features, it’s easy to accumulate technical debt. Early in my career, I ignored it, thinking it wasn’t my responsibility. Big mistake. Learning to recognize and manage it is a skill that will set you apart.
Actionable Tips:
- Regularly refactor code as part of your workflow.
- Understand the trade-offs between speed and maintainability.
- Advocate for writing tests to catch bugs early.

- Refactoring by Martin Fowler
- Understanding Technical Debt (Atlassian)
5. Build Projects Outside of Work
Your job might not always expose you to cutting-edge tools or give you the chance to experiment. Side projects are a great way to grow and show initiative.
Actionable Tips:
- Build something you're passionate about—this will keep you motivated.
- Share your work on GitHub or personal blogs.
- Try to contribute to open-source projects to gain real-world experience.

6. Impostor Syndrome is Normal
As a junior developer, it’s easy to feel like you don’t belong. Guess what? Even senior developers experience impostor syndrome! The key is to not let it hold you back.
Actionable Tips:
- Celebrate small wins—every problem solved is progress.
- Remember: You’re hired because you bring value, even as a learner.
- Focus on progress, not perfection.
? Resource:
- How to Overcome Impostor Syndrome as a Developer
7. Focus on Problem-Solving, Not Just Syntax
Memorizing syntax is not the goal; understanding how to solve problems is far more important. Tools and frameworks will change, but problem-solving skills will always remain relevant.
Actionable Tips:
- Practice solving coding challenges (but balance it with building real-world apps).
- Always ask why you’re solving a problem a certain way.
- Understand the trade-offs of different approaches.

Final Thoughts
Your early years as a developer are an opportunity to explore, make mistakes, and grow. Be curious, stay persistent, and remember: even the most experienced engineers were once beginners.

Create multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
