Like many in this world, I too strongly believe that one of the single most entities that changes the complete foothold of an organization in the competing global market is 'data'. Data is the one that provides information to business to take informed decisions. In addition, data is the one that dictates organizations to course correct the path towards the right future along with details on what happened until yesterday and what is happening today.
Throughout my career(and not bored of it yet), I have been in the data space building scalable and robust enterprise data solutions related to data warehousing and data mining, corporate reporting and analytics. In addition to that, there are other qualities of mine that come free with me:
- Leader with conviction and a programmer at heart
- Quick learner of the business situations and agile in developing solutions
Specialties: Client Relation building ▪ Resource Management ▪ Data mining and Corporate Reporting ▪ Capacity Planning and Project management ▪ ETL and Data warehousing ▪ Budgeting ▪ Change management ▪ Process Improvement ▪ Peer Reviews and Business Writing ▪ Team building and leadership ▪ Business Intelligence ▪ Master Data Management ▪ Analytics
Data and Analytics @ My contribution and role specifically in Walmart is all about "data" - from capturing to processing to mining to presenting.
I had the opportunity to lead the efforts to build our enterprise data warehouse and reporting platform from near scratch. The platform catered to business for several months with respect to providing information on what happened until yesterday and to an extent on what is happening currently.
With changing times, there was a constant dearth on why only a portion of customer activity on the website leads to effective transactions (sales). On that aspect, I was directly responsible to build and enhance our data platform that provides actionable insights to the business along with intelligence that could be fed back to the site to customize the experience that is suitable to the customers that shop which results in better customer engagement via personalization and product recommendations. It is made possible by incorporating semi-structured and part unstructured data, and then further mine it to determine behavior, trends and patterns from the customer activity (Omniture raw data and weblogs) and tie it to the structured transactional data which helps to draw parallel between customer shopping behavior and customer purchase behavior.
All of it with the data quality that is acceptable to be consumable to a greater degree.
