VP Global Finance Technology & Innovation


As documented by John Scott

I have served as Walmart’s vice president of global finance technology and innovation for nearly five years. When you are in a position to lead engineers and technologists, and you are striving to advance the capabilities of a company or a function, you have to understand what is feasible and possible technically. You have to understand how you can apply that technology practically to achieve the outcomes you seek. I wanted to learn more about what data science can do to accomplish such tasks and better understand the capabilities that exist so that I can apply them in other opportunities. I enrolled in Simplilearn’s Professional Certificate Program In Data Science with Purdue University.

The Importance of Upskilling

Life is a learning journey, and you should always look to learn. Everyone has their learning style, and you must stay plugged into what’s happening in the industry. Upskilling is important so that you can apply current learnings to solve business problems that have existed for years. You will have better solutions that way. 

How Upskilling Helps Senior Leadership

As a senior leader, you should know what your weaknesses are, and you should always choose to fill those gaps. Technology has taken a quantum leap in the last five years. There have been many changes, such as the ability to move massive amounts of data, the cloud, sharing computers across different geographies, accessing vast amounts of data, and synthesizing that data into something meaningful quickly. Although you can understand the theoretical component of it at a high level, knowing the actual technology behind it can give you a better framework of what’s possible. Knowing that is what upskilling does for anyone. 

Professionals Need to Stay on Top of Change

Yes, the expectation is that we all should seek opportunities to get better. If you are not improving yourself, you fall further and further behind daily. If you are not going forward, everyone else is leaving you behind. It doesn’t necessarily mean you have to take a year-long program, but the dedication to improve and grow in specific areas is important.

Data Science Can Improve Business Insights 

If you choose to upskill yourself, you already know that there is some deficit. I admit that I needed to upskill. I am in numerous business meetings where we discuss daily challenges. The challenges today are far more complex and require a significant amount of understanding. You have to know how the manipulation or acquisition of data can be applied to a given process. It can improve insights, get financial results, or help make determinations. I realized that data science is one methodology we can apply. It helped me to have that context and understand the process and steps needed to accomplish those goals.

Having a job that you are interested in and one that keeps you enthusiastic is relatively vital to boost work productivity. I did not realize this not until I lost my will to even continue my job. It had become a repetitive task that I no longer was satisfied with. So, that was the time I felt the need to literally upskill and choose another career path. 

The Journey 

I graduated from KCG College of Technology in Mechanical Engineering in 2016. Currently, I work as a Data Scientist at Ford Motor Company and live in Chennai, Tamil Nadu. I started my career by working as a Machine Learning Data Associate at Amazon in 2019. Later in June 2021, I became a Data Science Engineer at VuNet Systems. 

I am skilled in Machine Learning, Statistical Data Analysis, Machine Learning Algorithms, PostgreSQL, Data Analytics, Tableau, Microsoft SQL Server, SQL python, R (Programming Language), and RStudio. While working as a Data Engineer, I developed, built, experimented and maintained databases and large-scale processing systems. 

After nearly working for 4 years in the Machine Learning Data and Data Science Engineer field, I can feel that I am not as passionate as I used to be. As I was not getting any sense of full work satisfaction, I looked for other career opportunities. I am aware that Data Science is a thriving domain with plenty of work opportunities, so I wanted to move my career into the Data Science domain. 

The Simplilearn Course 

I enrolled in the Data Scientist Masters Program offered by Simplilearn to upgrade myself and learn new skills. I also completed Machine Learning Advanced Training and Tableau Desktop 10 Qualified Associate courses to upskill myself. 

Simplilearn’s Data Scientist course was a huge help for me in acquiring the required knowledge and skills, including Data Visualization, Statistical analysis and computing, Processing large data sets, SQL, etc. As my previous career was related to Data Engineering and Machine Learning, it has become easy for me to finish this course.
