7 Warning Signs That Reveal an Amateur Programmer (And How to Fix Them)

Massive Code Commits

Developers who submit large chunks of code in a single pull request make code review painful, cause merge conflicts, and delay feedback. The recommended practice is to break changes into small, functional commits and submit them daily.

Make small, daily commits.

Avoid committing code that fails to compile or breaks the build.

Poorly Written Code

Inexperienced developers often produce messy, hard‑to‑read code spread across the codebase, making it feel like navigating a maze. Before coding, they should fully understand the requirements, sketch simple diagrams, and design the solution on paper.

Understand the feature clearly before coding and ask questions.

Write clean, elegant code that teammates can read.

Working on Multiple Tasks Simultaneously

Novice developers may start a task without clarifying requirements, begin coding immediately, and juggle several unrelated features at once, leading to low output and wasted team time.

Focus on completing small tasks; break work into manageable pieces and prioritize.

Finish one task before starting another.

Arrogance

Arrogant developers reject constructive criticism, view feedback as a personal attack, and resist learning from others, which hampers their growth and damages team dynamics.

Stay humble and treat others politely.

Respect everyone, even when disagreements arise.

Failure to Learn from Mistakes

Developers who ignore feedback miss opportunities for improvement. A healthy feedback loop helps identify blind spots and encourages continuous learning.

Maintain a positive attitude toward feedback; consider acceptance calmly.

Learn from errors; lifelong learning keeps you strong.

Handling Personal Matters During Work Hours

Some team members browse social media, shop online, or trade stocks during work time, reducing their productivity and affecting the whole team.

Avoid personal activities during work; request leave if you must be away for hours.

Use breaks for social media, food delivery, or stock trading.

Blindly Chasing Tech Trends

Inexperienced developers often jump onto every new technology without applying it to real projects, turning learning into vanity rather than practical skill building.

Invest time in technologies that are truly useful for your work or projects.

Practice what you learn from tutorials rather than just following them.

Conclusion

Unprofessional habits lower both individual and team efficiency, causing missed career opportunities. Recognizing and eliminating these behaviors is essential for becoming a competent, successful software engineer.
