The journey of a self-taught developer can be both intense and overwhelming. Impostor syndrome often creeps in, causing you to question your skills and accomplishments. Adding to the challenge is the perceived divide between self-taught developers and computer science graduates, with some viewing the self-taught path as less legitimate. Despite these hurdles, many self-taught developers excel and thrive in the industry.
Like many others, I’ve made my fair share of mistakes along the way, and I hope this article helps you avoid the same pitfalls. Let’s explore some common mistakes and how to steer clear of them.
Mistake 1: Neglecting Pre-Coding Observations
Mistake: Inexperienced developers often jump straight into writing code, focusing solely on making it work without considering the bigger picture, such as maintainability, scalability, or how the code integrates with the larger system.
Why It Matters:
Code that works now may become difficult to update, debug, or scale later.
Overlooking the requirements or potential growth of a project can lead to costly refactors or complete rewrites.
How to Improve:
1. Understand Requirements: Before coding, clarify the project’s functional and non-functional requirements (e.g., performance, security, scalability).
2. Plan Your Approach: Design the system architecture, and consider how your code will integrate with existing components.
3. Think Long-Term: Write modular, reusable, and well-documented code to make future changes easier.
Mistake 2: Unorganized Code Changes in Pull Requests
Submitting large, disorganized pull requests (PRs) makes it harder for collaborators to review code and identify bugs or improvements.
Why It Matters:
Reviewing large PRs is time-consuming and error-prone.
Unfocused PRs introduce risks of unintended side effects, making debugging more challenging.
How to Improve:
1. Commit Frequently: Break your work into small, meaningful changes and commit them with descriptive messages.
2. Focus PRs on One Feature or Fix: Avoid combining unrelated changes in a single PR.
3. Test Each Change: Write tests for your code and validate every commit to ensure stability.
4. Use Code Review Tools: Tools like GitHub or GitLab’s PR review features can help manage feedback and discussions efficiently.
Mistake 3: Superficial Knowledge Accumulation
Constantly learning new languages or frameworks without deeply understanding core programming concepts.
Why It Matters:
A shallow understanding leads to a reliance on tutorials and limited problem-solving ability.
Mastering concepts like algorithms, data structures, and design patterns provides transferable skills across languages and frameworks.
How to Improve:
1. Focus on Fundamentals: Spend time mastering topics like object-oriented programming, functional programming, and software design principles.
2. Apply What You Learn: Build projects that challenge you to use your knowledge in real-world scenarios.
3. Depth Over Breadth: Stick with one language or framework until you’re comfortable solving complex problems with it before moving to another.
4. Learn a low-level language like Go/C++/C. Transitioning from a higher-level language like Python can deepen your understanding of fundamental concepts that underpin most programming languages, such as memory management, concurrency, and performance optimization.
Mistake 4: Task Overload and Multitasking
Working on too many tasks at once reduces focus, increases mistakes, and leads to incomplete or poorly implemented solutions.
Why It Matters:
Multitasking splits your attention and hampers productivity.
Prioritization ensures you deliver high-quality work efficiently.
How to Improve:
1. Use Task Management Tools: Tools like Trello, Asana, or Notion can help you prioritize and organize tasks.
2. Follow the One-Task Rule: Focus on completing one task before moving to another.
3. Break Tasks into Subtasks: Divide large tasks into smaller, manageable pieces to track progress and reduce overwhelm.
4. Avoid taking on too many tasks at once. A common challenge among self-taught developers is the desire to tackle multiple tasks simultaneously to demonstrate their competence. However, this often backfires, leading to incomplete or poorly executed work, ultimately making them appear less competent. Focus on quality over quantity to showcase your skills effectively.
Mistake 5: Fear of Criticism
Avoiding code reviews or feedback out of fear of criticism prevents growth and improvement as a developer.
Why It Matters:
Code reviews are an opportunity to learn best practices, identify mistakes, and improve code quality.
Feedback fosters collaboration and ensures consistency in team projects.
How to Improve:
1. Shift Your Mindset: View feedback as a learning opportunity rather than personal criticism.
2. Seek Out Code Reviews: Proactively share your code with peers, mentors, or online communities for constructive feedback.
3. Practice Giving and Receiving Feedback: Engaging in both sides of the review process builds confidence and helps you learn from others’ mistakes.
Conclusion
Self-taught developers often face unique challenges but can overcome them by adopting a mindset of continuous improvement, seeking feedback, and focusing on foundational skills. By addressing these common mistakes, you’ll develop stronger habits that set you up for long-term success in software development.
