I have 2 year experience in developing web applications in PHP programing language by using Maria DB database and small JavaScript snippets. I started to develop this type web applications since 2020 and created applications for labor time accounting, steel constructions production management, construction inventory rent and small e-seller company warehouse management.
I have 5 years’ experience in the development of Excel VBA programs. I also have 3 years’ experience in the using of C# programming language and I used to combine C# and Excel VBA programs in systems creation.
I achieved Microsoft certification "Software development fundamentals" in 10/2014 (fundamentals of C#, HTML, SQL Server, XML, CSS). My C# programming language knowledge is close to the certificate level (I took Microsoft exam "Programming in C#" in 03/2015 and 04/2015. My score was 681 - passing score 700).
I use Visual Studio latest versions for the Console, WPF, and MVC projects creation. I widely use generic List and HashSet collections and LINQ to Objects what do programs that operates with more than 3 million data rows much faster. I have the experience to work with complex data structures and to use created custom types (classes), multidimensional and jagged arrays, a list of arrays, or an array of lists dependently on input data and required reports structure. Several C# applications were created for data exchange through the internet with suppliers and sales platforms Web API (one application used WCF and data were exchanged in XML format, other used REST-API and data were exchanged in JSON format). One application used Azure Blob Storage for images (images were uploaded from FTP source into Azure Blob Storage folder with GUI name and they becomes available through URL, then after some fixed time the program for safety reasons delete this folder with all images). In applications for work with pdf files (inserting images, additional pages, text, barcodes, hiding some existing text) was used iTextSharp library and for barcodes creation Zen.Barcode library, for faster data reading from Excel files was used ExcelDataReader library and for faster Excel reports formation EPPlus library. I like to be a part of the developers’ community - my StackOverflow account.
I develop Excel VBA and C# applications to a company that sells products through the world’s largest online retailers (Amazon, eBay and other) from 2016 January until 2020 February and maintain these applications now. I develop Excel VBA and C# applications for construction companies’ information systems from 2012 until 2014 and from April 2019 until now.
I have excellent knowledge of accounting and advanced information systems implementation. I was awarded the qualification degree of a Master of Economics (With Excellence – 2005. My master's thesis was about construction companies ERP (Enterprise Resource Planning) systems) and the qualification of an Electronic Technology Engineer (1985). I have 3 years’ experience as an IT department manager (advanced software systems implementations) and 15 years of professional experience in accounting and finance. The combination of economic and technological education and experience allows me quickly to understand production and information technologies and their relationship with economical information which is needed for decision-making.
I have a lot of experience to work in teams and communicate with different level managers and specialists. My English is fluent in the professional fields.
