Over a year ago, I lost my job due to the Covid-19 pandemic. This was a blessing in misfortune.

Exactly one year ago, I was working part-time as a tutor while studying.

During this time, my income was just above minimum wage, just enough to cover expenses like food and gas.

I lost my job during the pandemic and was told I could only return to tutoring after the nationwide lockdown was lifted.

After that, I suddenly realized that I had a lot of free time. I no longer had to take college classes. And I lost my job.

I took this opportunity to learn data science on my own.

And by using the data science knowledge I learned to create multiple streams of income, I was able to triple my salary in just over a year.

How I tripled my income:

1. Data Science Jobs

I managed to get into a data science internship that turned into a full-time job offer.

According to Selvaraj’s June 2020 Medium post, ” Data Science Projects Get Jobs, ” he was hired as an intern at one of Asia’s largest telecommunications companies before completing his degree in data science. rice field. The decisive factor in the hiring was the portfolio of data science projects that he independently worked on . See also the AINOW translation article, “Honestly , Online Courses Won’t Make You a Data Scientist
” for the importance of independent data science projects .

There are two benefits to taking a full-time job in data science.

(First) The compensation I get from data science work is not a big part of my income, but I like it because it’s stable.

And (second) learn something new every day. Developing communication skills when talking to people across different teams, building and scaling machine learning models to work with large datasets, and thinking of different techniques to improve customer journeys. there is

The most appealing thing about this job is that unlike freelancers, you can’t choose which project you’re in charge of.

You have no choice but to learn in a day or two or finish the project even if you don’t know how to do it.

Most of the time I complete the task and come home learning something new.

Also, because of my introverted personality, I was not good at communicating with people and making presentations at team meetings.

In my work as a data scientist, I often present model insights and collect business requirements from clients, so even if I am not good at communication, I had no choice but to carry out my work.

However, thanks to that, my communication skills have improved dramatically over the past year.

2. Data Science Blog

In my spare time (usually evenings and weekends), I write for data science .

Selvaraj’s articles on data science can be found on his Medium articles page . He usually posts about 3-4 times a month.

I started by writing articles about the projects I was involved in to strengthen my portfolio.

I love to create, and my articles have become a way to share my journey of becoming a data scientist with others. When I started writing articles, I had no friends to study with, and no one who was interested in data science like me.

I wrote this article to document my progress and connect with a community of like-minded people with similar goals.

As I was writing the article, I realized that my article would add value to those who were on their way to becoming data scientists like me.

As I continued to write articles, what started as a hobby turned into an income.

By simply writing about my experiences and posting them online, I was able to earn passive income.

Now a Top Writer on Technology and Artificial Intelligence at Medium , this was more than I could have imagined.

3. Affiliate Marketing

Since I started learning data science on my own, I’ve been sharing links to courses I’m taking on Medium and LinkedIn.

However, I only recently encountered affiliates.

Affiliate marketing allows you to share courses you enjoy with others. If someone clicks on a course link you share, you get a small percentage of the course fee they pay.

I haven’t made a lot of money as an affiliate yet, but that’s mainly because I’m picky about the courses I promote.

I’ve taken almost every course they advertise, and I’ve thoroughly researched and compiled the rest of the material I haven’t taken.

That’s why affiliates are such a small source of income, but I’m adding them to this list nonetheless.

4. Freelance

Last year I was looking for a way to make money online.

I desperately needed a new source of income, so I was researching sites like Fiverr and Upwork to see if I could take on some gig work.

(*Translation Note 3) Fiverr is a gigwork brokerage platform founded in Israel in 2010. In 2019, it went public on the New York Stock Exchange. Upwork is a freelance platform founded in the United States in 1998. Over 12 million freelancers and 5 million clients signed up in 2017, and went public in 2018.

But these platforms are so competitive that I didn’t feel like I fit into any of these sites’ categories.

After studying data science, I realized that there is a fairly large market for freelance data scientists.

There are many companies out there that don’t need an entire data science team and hire people on a contract basis to build and implement models for them.

I’m currently working on a one-off machine learning project for a client and I’ve learned a lot from it.

There are also offers from publishers and tech sites to write freelance data science articles.

All of my clients read my articles and LinkedIn posts and contacted me. That’s why writing data science articles on Medium and building a social media following is a great idea.

More recently, I’ve also started offering consultation sessions for people looking to learn data science or enter the industry, which is another source of income for me. . Again, most of my clients come from my LinkedIn profile and Medium posts.

(*Translation Note 4) DDIChat , which provides a service that matches clients who want to consult experts with experts, has a page to apply for Selvaraj’s consultation . The page contains the following introductory text:
Getting a data science job without a master’s degree and no experience is difficult, but not impossible.
If you’re new to the data industry and confused by the various career options, unsure how to start learning data science, or want to get into a data science job, join me for a DDIChat session. can be booked.
By the way, Mr. Selvaraj’s consultation costs $30 per 30 minutes.
(*Translation Note 5) For information on undertaking data science work as a freelancer, see AINOW’s translated article, ” 7 Types of Gig Work You Can Do as a Freelance Data Scientist “.


Losing my tutoring job due to Covid-19 was one of the best things that happened to me.

I found myself stuck for a long time not knowing what to do in the future. Losing my job at that time gave me some free time to reflect, learn, and decide what I really wanted to do.

Of course, I was fortunate to have survived unemployed for so long and had the opportunity to learn the skills necessary to actually become a data scientist.

Learning and learning how to code was one of the best decisions I’ve ever made in my life.
