Learning is a prerequisite to thriving in tech due to the speed at which the industry is evolving. There is always something new to learn.

Once you stop learning, you start dying — Albert Einstein

Search efficiently

As a developer, you will use search engines very often and a majority of search engines offer advanced features. See tips and infographics

Development IDEs

IDEs such as IntelliJ, Atom come with shortcuts, plugins and features aimed to increase your productivity. Invest a little time to learn how to best use an IDE.

Learn Linux

Installing Ubuntu natively, using VirtualBox or Windows Subsystem for Linux is a piece of cake. Linux/Unix knowledge is a huge plus.

Learn Git

Git is one of the most popular code versioning tool. I suggest start Git-ing as early as possible with your projects and assignments. A great way to learn Git is through documentation, article and maybe this interactive online resource.

Teach Yourself

It is a fact that your program of study does not prepare you for real world regardless of university’s ranking, depth of the curriculum or caliber of the professors. Nowadays there is no shortage of learning materials both offline and online.

crunchzilla is a step by step how to code games for beginners. My favourite Youtube channels are Derek Banas, LearnCode Academy, FreeCodeCamp and CodingTech. Finally, a listing of open courseware on EDX, Stanford Online, and MIT OpenCourseWare that you could learn from.

Learn at least one language concretely

At university, I studied C Programming for 2 years from Basics to Advanced Data Structure. It helped build a strong programming foundation and every other language become a mere change of syntax, terminology and structure.

Focus on Simplicity

You will be surprised how in-demand simplicity is when it comes to coding and no one admires code that is complex, hard to understand and maintain.

Simplicity is a prerequisite for reliability. — Edsger W. Dijkstra

Coding Standards Matter

It is very common for code to migrate from one dev to another over it is lifespan. It's critical to follow a commonly adopted coding guidelines to ensure that the code is easy to understand, extend and maintain. Click the image below to read my article on Java Coding Best Practices.


Learn Design Patterns

Similar to coding standards, knowledge of design patterns help you architect close to immortal systems (ok maybe not immortal, but you get the point).

Listen to tech podcasts

Podcast are great ways to broaden your technical knowledge when commuting, walking, driving and so on. I would highly recommend checking out the Software Engineering Daily podcast.

Communities & Profiles

Communities are where you network with like minded professionals, learn and give back.


Creating a profile allow you to setup your own repos, follow inspiring contributors, appreciate others work by staring their repository, and most importantly contribute back to the open source projects. Here is my GitHub profile.

How to contribute? You can report a bug, write documentation, answer questions, fix issues and create new features.

It’s worth-mentioning that, employers favour open source contributors.


StackOverflow is the largest Software Development Q&A website. A SO profile is good to have. See Rob’s comment on its significance in interviews.

  • Ask difficult & meaningful questions
  • Answer questions
  • Upvote useful questions/answers


A LinkedIn profile is the first step towards building your online presence.

  • Build your professional network
  • Subscribe to updates from companies & influencers
  • Explore jobs, write and read posts

Similarly, AngelList and IndieHackers, Reddit are great communities to be a member of. See my profile below for my profiles.

Developing a few habits early on would greatly help you down the road. I highly recommend reading The Power of Habit by Charles Duhigg.

  1. Tech is a fast-paced industry. Stay up to date with social networks & sites such as slashdot & techcrunch.

  2. Don’t be shy! Ask for advice from those with expertise

  3. Always plan and solve the problem in paper and then write the code. This is very powerful.

  4. Write code that aligns with industry adopted coding standards. Start writing tests early for assignments, projects.

  5. Develop a habit of solving puzzles/challenges on regular basis. This will serve you dearly whether it’s interview, your job, side project, etc.

  6. Whiteboarding skill never let you down whether it is interview, on the job. Probably one of the most overlooked skill.

  7. Understand how much time you have in your hand and use it wisely. Do the math, calendar block tomorrow and use RescueTime/Toggl if you are comfortable with their Privacy Policy.

  8. Protect your identity by reading privacy policies, terms of services, using VPN & Encryption, password manager, enabling 2FA, and so on.

Socializing & Networking

There are many benefits to networking and socializing such as

  • Build your professional network
  • Get inspired and inspire others
  • Learn about the dev communities, jobs, mentoring, volunteering, etc
  • Find your co-founders and project partners
  • Improve your soft skills i.e. speaking, active listening, and so on.

We are well past the era of one man army, it is all about teamwork now. Get to know people of all expertise i.e. legal, finance, sales, marketing and so on. It will come handy in the future be it side projects, change industry, etc.

If you find networking difficult, I recommend reading self help books i.e. Quiet: The Power of Introverts in a World That Can’t Stop Talking and there is a ton of tips and advice on internet.

Follow Influencers & Companies

Put social networks into good use. Follow people and companies that inspire and remind you of your dreams and goals. I use social networks to

Side Projects

Act on your ideas. The chances that someone else is thinking about it is very high.

  • Pick that great idea and do a feasibility and market research
  • Connect with your professional network to find partners & co-founders
  • Work in your free time while maintaining a healthy work/life balance & don’t forget to see the idea through completion


As a Software Developer you will be constantly learning and researching. Give yourself the habit of reading the documentation first and if that did not help then search for other learning materials such as examples, tutorials, etc.

Error Messages

Don’t be disappointed when you come across an error message. Learn What is it about? When does it happen? and How to handle it gracefully?

Choose the right Company

Recently, I came across this article by Brenn where he explains the benefits of working for a Product vs Consulting company — Might help decide your next career/internship option.

SEO Yourself

Have you ever googled yourself? Is your personal information safe? Is your public information easily accessible? Use the magic of search engine to achieve your objectives whether it’s sharing wisdom, promoting your brand, attracting followers, or spreading awareness.

Things you should avoid

It takes time to build and remove habits.

Do not give up easily

There are different cues that lead to giving up. As a software developer you will easily come across

  • Annoying issues
  • Poor legacy code
  • Learning other languages, tools, and domain knowledge
  • Working with people who have different coding habits, opinion, etc

It is generally a good habit not to give up and keep trying but, don’t be stubborn and understand when is the right time to let go and move on.

When it comes to coding, if you are on the verge of giving up, try following

  • Take a break and come back later or the next day
  • Try solving it on paper
  • Ask for help from those with expertise

Do not copy assignments

When I started my computer science degree, the first C programming assignment was “Write a program that computes x^n (x to power of n) using + (plus) and — (minus) operators where x and n are integers provided by the user”.

It took me a long time with no access to internet to find a solution on paper. I learned not to give up and keep trying and the future assignments become easier and easier.

Do not fall for social network addiction

Believe it or not, a majority of social networks are powered by algorithms that have one goal — Increase the ROI for the company using your time.

Do not lose hope, you are smarter than you think

Lastly, feeling hopeless and worried is going to be a frequent visitor and you will have to learn how to deal with it. Here are a few points in your defense

  • Don’t let knowledge gap make you worry or hopeless — see article below
  • Don’t be intimidated by those who are better — You will get there
  • Don’t lose hope for not knowing everything i.e. AI, Machine Learning, Blockchain, etc — you will learn them eventually

Dan Abramov, one of the developers I follow is the co-creator of famous Redux framework wrote the following article that I consider a great read.

Thanks for writing it up. It all looks well, but I think this remark made me chuckle a bit Work in your free time. If you work in your free time then that free time is not free anymore. I thought the idea of work is to buy back some of your personal time to do no work. My experience tells me to take your free time and sometimes do nothing, go for a walk, don't take any podcasts/books with yourself but just sit down under a tree, relax and listen to the surrounding. Talk to your close ones, strangers and sometimes just engage in mindless conversations. Your mind requires time to recuparate from processing and high intensive load. Otherwise you will burn yourself out. But feel free to ignore my remark, this is how I deal with my stubbornness to let go.

Thank you kamilliano for pointing it out. I strongly agree with you on that front whether it's to do with burn out or plain simple enjoy life. A healthy balance of work and life is definitely important.

When I wrote the article, I was with the mindset that, just like work, socializing, fun, exercise are also important and if any time left then it's free time but, I suppose it could be interpreted in different ways and I could have been more clearer.

I will update the line to make it clear.

I agree. Maybe the sentiment should be "learn in your free time if you want to ". It shouldn't be a requirement. It can be a slippery slope for overworking or fatigue. For juniors/recent graduates it's worth asking how much time the company would provision for learning, and what kind of learning. If a company isn't offering learning time/resources for you to learn (courses, conferences, etc) they shouldn't be hiring a junior.

Also learning linux is not needed if your machine is unix based 😛

These are some well thought out points and a well written article! And I do agree that you have to let go of some free time to be able stay up to date with every change happening in the world of technology! 👌

But again.. Let your brain recharge is almost as important to be honest 😛
