Using Excel played a key role in all of my previous positions. I used Excel on a daily basis to prepare various analyses as part of my work.
I have several years of experience creating and interpreting pivot tables and performing data operations using the VLOOKUP and HLOOKUP functions.
I used Excel to prepare data for input into ERP systems like SAP.
My experience in this area includes converting large amounts of data from Excel format into CSV files, as well as creating Excel files from CSV and TXT files using the Text-to-Column feature.
I used IBM SPSS for a short time for testing purposes.
I started learning SQL in 2022. Since then, I have created databases for both personal use and web development.
I have used SQL for websites that allow user logins, as well for databases designed to generate custom reports.
I have been working with the SAP FI module since 2011. In the FI module, I performed tasks related to master data.
This includes the regular reconciliation of SAP FI customer line items data (FBL5N transaction) with other systems.
I was also responsible for reconciling customer invoices compared to SAP data.
Thanks to my background in economics and accounting, I am able to interpret the accounting implications of the business events represented by transactions in SAP FI. I can also assist in the creation of process flowcharts.
I have gained work experience with FI and CO modules in SAP. I have a total of more than 7 years of experience with SAP.
I began learning HTML and CSS for personal development in 2020.
Since 2021, I have a presence on the Internet with websites I created myself, typically blogs.
John Duckett's book: HTML & CSS - Design and Build Websites helped me master HTML and CSS for frontend development.
As for more advanced CSS, I have learnt a lot from Ben Frain's book: Responsive Web Design with HTML5 and CSS.
For the Bootstrap framework, I took a course on coursera.org, this online course was Responsive Web Design by University of London.
I started to learn the backend part of web development as well - Robin Nison's book: Learning PHP, MySQL & JavaScript is of great help.
I am also creating websites with the help of the CMS system WordPress.
