Being a solo developer accelerates learning but can create blind spots in the long term. Lack of feedback, missing code reviews, and limited technical discussions can introduce quality risks. In this article, we explore the advantages, risks, and solutions of working as a solo developer with real-world examples.
Being the only developer on a project is something many developers experience at different stages of their careers. This is especially common in startups, small teams, or early-stage products. From the outside, this situation often looks advantageous. You make all the technical decisions, development moves faster, and you gain experience across a wide range of technical areas.
Working as a solo developer is indeed very educational in the short term. However, it also brings some risks that are harder to notice in the long run. The most important one is the lack of feedback. Because software development is not just about writing code, it is also a process shaped by discussion, collaboration, and different perspectives.
When you work alone, this process naturally disappears.
When you're the only developer, all responsibility falls on you. From frontend development to backend architecture, from performance optimization to deployment processes, you are forced to make decisions in every area. This naturally pushes you to learn faster.
Imagine being the only developer in a small project. You design the backend API, decide the frontend state management approach, and solve performance issues yourself. During this process, you inevitably start making architectural decisions.
This situation is especially valuable in certain stages of your career. You gain experience across multiple areas and start seeing the system as a whole. You gradually move from being someone who just writes code to someone who thinks about the product.
However, alongside this rapid growth, an invisible problem begins to emerge.
The biggest missing piece when working as a solo developer is feedback. There is no one reviewing your code. There is no teammate to discuss architectural decisions with. As a result, you start evaluating your code only from your own perspective.
This gradually creates technical blind spots.
For example, imagine you choose Context API for state management in a project. As the project grows, performance issues begin to appear. If there were another experienced developer on the team, this decision might have been discussed early and a different approach could have been chosen.
But as a solo developer, these decisions often continue without being questioned.
Another example is folder structure. At the beginning of a project, a simple structure may seem sufficient. However, as the project grows, this structure becomes harder to maintain. In team environments, this is usually noticed early and refactored. When working alone, these changes are often delayed.
This leads to growing technical debt over time.
Code review is not only about finding bugs. It also improves readability, strengthens architecture, ensures consistency, and encourages knowledge sharing.
For example, imagine writing a function like this:
The code works. However, in a team environment, someone might suggest:
"Would it be more readable if we split this into smaller functions?"
Or another developer might suggest a performance improvement.
When working alone, these kinds of improvements rarely happen. Because if the code works, it is often considered sufficient.
Over time, this quietly reduces code quality.
Technical discussions in good teams are extremely valuable. These discussions often start with small decisions but significantly improve a developer’s perspective.
For example:
"Should this component be reusable or page-specific?"
"Do we really need memoization here?"
"Should this logic be extracted into a custom hook?"
These discussions improve not only the code but also the developer.
When working alone, these discussions disappear. Over time, this may lead to repeating the same patterns and solutions.
As a solo developer, you may gradually build your own comfort zone. A specific folder structure, a familiar architecture pattern, or a preferred state management approach.
When a new developer joins a team, they often question these decisions. But when working alone, this questioning rarely happens.
This can slow down technical growth.
Even if you are a solo developer, there are still ways to get feedback. Contributing to open source projects, sharing technical articles, and engaging with developer communities can be very helpful.
For example, when you share a technical article, you may receive feedback from other developers. Sometimes these comments can be as valuable as team code reviews.
Contributing to open source projects is also highly beneficial. When you open a pull request, other developers review your code and provide feedback.
These interactions reduce technical blind spots and make your growth more sustainable.
Being a solo developer accelerates growth in the short term. However, in the long term, lack of feedback can create technical blind spots. Software development may look like an individual activity, but in reality, it grows through collaboration.
Great developers don’t improve only by writing code — they improve through different perspectives and feedback.
Even if you work alone, creating environments where you can receive feedback is important.
Because great code is rarely the product of a single perspective.
