Do You Collectively Decide What Data Science Problems To Work On Or How Do You Decide That
As I mentioned, the data science problems we focus on are very close to society so we focus on few business domains which we call – HEARTS
H – Healthcare
T – Transportation
S – Smart city
These are the primary focus areas. At the same time horizontally we cut across with respect to the technology with natural language processing , computer vision, speech technology to some extent IoT and robotics as well which we like to call embedded intelligence where we try to embed the machine learning or deep algorithm itself in the hardware side as well. Then we have collaborated with multiple governments including the Government of India, State Governments of Telangana, and West Bengal. We are also working with multiple academia such as IIIT Hyderabad, IIT Kharagpur, ISB Hyderabad.
When you started off there was really nothing defined called data science yet it was analytics broadly. What has changed from then to now when it is suddenly cool data science is very much in demand? How have data science job roles changed?
So the biggest transformation in your experience has been this scale-up of processing power, hardware, data science, and machine learning libraries and interfaces and APIs?

Going Freelance As A Data Scientist
Although most people who study data science are looking for full-time employment with an established company or startup, its worth remembering that data science skills afford you the opportunity to work as a freelancer.
Its not uncommon that companies have data science work, but not enough of it to justify hiring a full-time data scientist. Its also not uncommon for companies with a new interest in data science to hire a data science consultant and work through a few freelance projects before committing to permanent data science hires. And of course, even companies with established data science teams may need extra help from time to time. These are all potential clients for a freelance data scientist or data science consultant.
Advantages of Freelancing
You can make more money. Depending on the client and the project, a data scientist with a full suite of skills (like someone whos gone through most of our Data Scientist path can charge rates of $100 to $200 per hour or even more. Often, youll be able to make more while working fewer hours per week than you might as a salaried employee.
You decide what you do. Early in your freelance career, you may not have a lot of choice in what projects you take. But once youve established yourself as a reliable and skilled freelancer, youre likely to find you have the freedom to pick and choose the projects or companies you work with.

I see two other answers where they advise you to switch to analytics if you like it. I would like to point out a few realities to you so that you know what they all assumed you have. I assume you have some experience under your belt in finance.
Learn Some New Programming Languages
Most data analysts get by with a solid understanding of Python. Data scientists usually add the programming language R to their arsenal, too. Check out someintroductory tutorials for R, or advance your Python skills by building applications in your spare time. Whatever you do, challenge yourselfyoull learn best by experimenting and making mistakes. Aim to upskill in other technical areas as well, for instance by playing around with distributed computing or statistical tools.

Do You Have Experience In Data
We regularly encounter talented business intelligence professionals looking to land their first data science role. They are often frustrated by the perceived lack of opportunities for them. A lot of them feel that their role is repetitive, or they just need to perform whatever has been asked of them.
They actually miss the fact that they are closer to data science opportunities than any other professional out there!
Why transition into data science in easier for a Business Intelligence professional:
Business Intelligence professionals hold a massive advantage over almost anyone trying to transition into data science because of the following reasons:
- BI professionals already have access to data scientists in various projects
- Existing know-how of how to manage and handle data
- BI professionals have the business context and they work closely with businesses
- They have experience with basic data exploration steps as very often business asks for these in addition to the reports they use.
In other words, these folks work in the first half of a data science project. Thats already more industry experience than most aspiring data scientists!
Develop Your Math And Model Building Skills
As a data analyst, you will be extracting, munging, and visualizing data to aid business decisions. Though mathematical logic is involved in the analysis part, its not heavy math. Data analysts are usually inclined towards the minimal requirement of mathematics while data science requires a strong mathematical foundation.
As a data scientist, you will have to write algorithms from scratch requiring an in-depth understanding of linear algebra and calculus so advanced math is an absolute necessity to understand how a machine learning algorithm works and behaves. Having a strong mathematical base helps understand the nature of the machine learning model and how it can be tweaked to improve its accuracy. Even if you are using the predefined libraries, it is essential to understand the calculations that are being performed behind the scenes before you can actually apply them to the actual business problem.
Apart from making maths your friend, you will need to enhance your model building skills by working with your peers and other data scientists to solve challenging business problems. This will help you explore your model building skills and evaluate them.
