What I Wish I Knew as a Junior Developer: Advice from a Senior Engineer

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.

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.

• 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.

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.
