Portafolio

Created a function in R to do data calculation using packages like data.table, lubridate, and dplyr.

R Code for Data Manipulation

The task involved getting geocoded address from the regular address and finding the distance between them.

Analyzing Data based on Geolocation

Preview of dashboards created using Excel and Excel VBA.

It uses:

Excel Dashboards

I have been working as Freelancer across multiple marketplaces. The images here represent the statistics from one such marketplace of freelancers.

On this platform, users post their Excel issues (problems with formulas, VBA, Excel Solver, Graphs, Data Analysis) and the expert (i.e. freelancers) bid for the problem to solve. Till now, I have solved such 338 sessions (as of March-2019) since I joined in the second half of December 2018.

I have received some amazing comments from the users which helps me to focus on freelancing.

Project for Abhishek M. -- 20/08/06 17:52:22

This was an extension of an earlier project that Abhishek completed to include additional calculations to the existing data set. Coding was done in python. The project was completed on time and the coding was accurate. Very happy with the work. Thank you.
