Karthik T Python, SQL, Excel/ VBA, Power BI, Access
10 Reviews

A Python, SQL Server, MS Excel/ VBA, Access, Power BI geek for more than a decade now (What !!? Over 1/3 rd of my time so far on this planet punching keys).

Somewhere down the line I developed a penchant for teaching. So, I set sail on a journey as a corporate trainer (where I got the opportunity to rack the brains of my colleagues). Later, for greater satisfaction, thought why not (torture a lot more people) disseminate the little knowledge, imbibed so far, to my far fledged friends. Hence I chose to conduct Online Classes (thanks to Tim Berners-Lee, Bob Kahn and Vint Cerf - hats off to u guys !!) through the trustworthy and transparent website of TeacherOn. Kudos to it's magnificent and magnanimous leader Arun Verma and his delightful and diligent team.
Gracias ! Merci !! Dánke !!!

Now, let's talk business...
W.r.t Python programming, I conduct Online classes consisting of the foundation course, followed by Intermediate and Advanced modules, depending on your specific requirement (Process Automation, Data analysis and visualization, Data Science, Database Management (SQL libraries), Website development, Web scraping, Game development, Microcontrollers, Network Automation).

Database Management System (SQL Server and MS Access) Yes! I also query and annoy databases too.

Excel/ VBA (my bread and butter when incipient) - I specialize in data analysis, data processing and modelling, dashboards, templates and reports, automating tasks, financial modeling.

Power BI - For the fortunate (or unfortunate) souls who wrangle with bigger data - I teach this more sophisticated data analysis and dashboarding tool.

Above all, I am ardent about converging with my fellow species worldwide (obviously online, but would certainly be elated to meet in person also, if invited :-) ) and learning stuff from you too.

Having been a corporate trainer in a Fortune 500 company for over n years, I proclaim and certify myself to have good understanding of business requirements ; ) I teach tools and techniques that, as much as possible, simulate and solve real-world problems.

It's been a fantabulous expedition with Teacheron. I've got opportunities to interact with many awesome people world over... countries in all continents (except Antarctica - hopefully humans will not have to inhabit the penguin's pristine place).

Get onboard, let's embark on a beautiful journey and experience nirvana.. sorry just exaggerating. Long live Captain Bill and Captain Guido !!

My Hearty Thanks to my wonderful comrades for showering so much benevolence on me in the form of stars for my Review. Wish you All the Best for whatever good deeds you pursue.

Proud to be a Global Tutor and associating with all of you splendid personalities.
