The Differences Between a Junior, Mid-Level and Senior Developer

Being a junior, mid-level, or senior developer doesn’t solely have to do with the years of programming experience that you have. A junior developer can even be older than a senior developer. It all comes down to skill. This doesn’t mean that a senior developer has to be an expert in everything, but it’s safe to say that senior developers are far more skilled than junior and mid-level developers.

But more than just coding skills differentiate the senior developer from the mid-level and junior developer. So what exactly are the differences?


Obviously the senior developer has far more knowledge than the junior and mid-level developer. Knowing design patterns, architecture, automating testing, performance, security, etc. is a good way for a junior developer to close the knowledge gap with the mid-level and senior developers.

It’s important to know how things in software development should be done. But just knowing all this stuff doesn’t make you a senior developer. Knowledge isn’t the biggest difference between developers—it’s just one of the factors.


Despite what most people think, coding is not about communication with a computer. Coding is about communicating with humans and instructingcomputers. Eventually, code gets compiled and translated to zeroes and ones.

Code has to make sense for other developers that have work with it in the future. A new team that has never seen the code before should be able to open the code and start working on new features or bug fixes. This is where the big difference is between junior and senior developers.

I will leave out the mid-level developer in this comparison because the mid-level developer is kind of a gray area when it comes to coding skills. Obviously, it is somewhere in between the junior and senior. It probably leans more towards the senior side. This mainly has to do with experience, since mid-level developers have probably been through the whole development cycle at least once. They have made a lot of the most simple mistakes and learned from them.

How to sniff out the junior developer?

Junior developers are inexperienced. Some just graduated and are starting their first full-time job. The mindset of a junior developer often is to just make the code work. Working software and good software are considered the same.

Programming straightforward code is hard. And it’s something that junior developers don’t do. Junior developers write fancy code. You can recognize the junior developer by quirky one-liners and overly complex abstractions. This is the junior developer's way of showing off and letting the other developers know how good they can code. And it’s wrong.

Junior developers focus on the computer side of the code at the expense of the human side.

And what about the senior developer?

When looking at the code of a senior developer, you might think: is this all there is? Where’s the rest of the code? A senior developer writes simple, straightforward, and maybe even dumb code. This is one of the biggest qualities that a developer can have when it comes to programming. A senior developer follows the KISS principle: Keep it simple, stupid.

A senior developer thinks about their code in a different way than the junior developer. Code written by a senior developer will be made with maintainability and scalability in mind. This is a totally different mindset than the junior developer has—the senior is thinking about the people who have to work with the code, while the junior is just thinking about making it work for the computer.

More Than Just Coding Skills

Besides coding skills, there are some other factors that can tell you who’s what type of developer.

Junior developers, in general, do the most simple tasks or tasks with low impact. They don’t do any design of architecture. Mid-level developers are not designing solutions either, they just perform tasks. The difference with the junior developer is that they perform those tasks with less supervision as long as they are assigned to relatively routine tasks. Senior developers can develop an application completely on their own.

It doesn’t mean that the senior developer doesn’t have any questions along the way. Every developer has a lot of questions every day and that won’t change. That’s no different for senior developers.

The difference is that senior developers know how to ask the right questions and how these questions get handled. Mid-level developers can ask the right questions when it comes to their relatively routine tasks, but need help on more complex tasks.

The senior developer is never lost and knows how to follow up the question with the right action. This doesn’t mean that a senior developer can’t ask help from other developers. Sometimes the best way is to just ask other developers with experience in that area for help.

The mid-level developer should be able to ask the right questions as well, as long as he doesn’t get assigned highly complicated tasks that require an in-depth level of knowledge.

You shouldn’t expect a junior developer to ask the right questions straight away. Since junior developers are inexperienced, they need guidance from a more experienced developer. The junior developer needs to get provided with the necessary resources or a big push in the right direction.

Getting to the Next Level

We all want to improve ourselves and get better as a developer. But what are the steps that you can take to get to the next level?

Junior to mid-level

Since junior developers are inexperienced, it is important to go through the whole development cycle at least a couple of times. This way you will fall into a lot of traps and learn how to avoid them the next time.

When it comes to coding, you should learn how to write simple code. Think about the next person that is going to work on that piece of code. You should also learn how to debug, since this will give you a better understanding of what’s going on in the process.

Furthermore, you should get familiar with best practices and learn about architecture, performance, security, etc. Close the knowledge gap that is required to get to the mid-level.

Mid-level to senior

Getting from mid-level to senior can be quite hard. Some developers will stay mid-level for the entire length of their career.

Senior developers know what corners can be cut and what corners should never be cut. These are hard-learned lessons by making mistakes in the past.

If you want to get to the senior level, you have to be prepared to take the tasks that no one knows how to fix. You should know more than just how to get the job done.

As a senior developer, your job is also to help the less experienced developers. You are the fallback for other developers when they don’t know how to do something.

And it might not surprise you that senior developers master their tech stack. There is more than just coding skills. Get to know all the tools and applications that are being used within the company that you work for.


The difference between a junior, mid-level, and senior developer isn’t all about years of experience. Sure, it’s safe to say that senior developers are more skilled than junior and mid-level developers. But knowledge is not the most important factor.

Senior developers write easier code and come with a different mindset than junior developers. But it’s about more than just coding skills. Knowing what questions to ask and how to follow up on those questions is essential. And it is something that only the senior developer, with their wealth of experience, knows how to do in all situations.

To grow as a junior developer you should focus on writing simple code and going through multiple development cycles. To get from a mid-level to senior developer you should focus on learning more than just fixing routine tasks. You should be willing to take the hardest tasks and be a master of your tech stack. Another responsibility of a senior developer is to be the fallback for less experienced developers.

I’ll leave you with a quote from Martin Fowler: “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.”

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research


_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.

Developer Career Path: To Become a Team Lead or Stay a Developer?

For a developer, becoming a team leader can be a trap or open up opportunities for creating software. Two years ago, when I was a developer, I was thinking, “I want to be a team leader. It’s so cool, he’s in charge of everything and gets more money. It’s the next step after a senior.” Back then, no one could tell me how wrong I was. I had to find it out myself.

I Got to Be a Team Leader — Twice

I’m naturally very organized. Whatever I do, I try to put things in order, create systems and processes. So I’ve always been inclined to take on more responsibilities than just coding. My first startup job, let’s call it T, was complete chaos in terms of development processes.

Now I probably wouldn’t work in a place like that, but at the time, I enjoyed the vibe. Just imagine it — numerous clients and a team leader who set tasks to the developers in person (and often privately). We would often miss deadlines and had to work late. Once, my boss called and asked me to come back to work at 8 p.m. to finish one feature — all because the deadline was “the next morning.” But at T, we were a family.

We also did everything ourselves — or at least tried to. I’ll never forget how I had to install Ubuntu on a rack server that we got from one of our investors. When I would turn it on, it sounded like a helicopter taking off!

At T, I became a CTO and managed a team of 10 people. So it was my first experience as a team leader.

Then I came to work at D — as a developer. And it was so different in every way when it came to processes.

They employed classic Scrum with sprints, burndown charts, demos, story points, planning, and backlog grooming. I was amazed by the quality of processes, but at first, I was just coding and minding my own business. Then I became friends with the Scrum master. I would ask him lots of questions, and he would willingly answer them and recommend good books.

My favorite was Scrum and XP from the Trenches by Henrik Kniberg. The process at D was based on its methods. As a result, both managers and sellers knew when to expect the result.

Then I joined Skyeng, also as a developer. Unlike my other jobs, it excels at continuous integration with features shipped every day. Within my team, we used a Kanban-like method.

We were also lucky to have our team leader, Petya. At our F2F meetings, we could discuss anything, from missing deadlines to setting up a task tracker. Sometimes I would just give feedback or he would give me advice.

That’s how Petya got to know I’d had some management experience at T and learned Scrum at D.

So one day, he offered me to host a stand-up.
