Curriculum vitae

Overview

I have a broad outlook in the field of IT. I was engaged in both development and analytical work in the fields of intergovernmental information exchange and healthcare. Also I have experience in statistical analysis of medical data, experience in BI development and considerable experience in web development. At the moment, I’m most interested in model-driven development, EDI and data analysis.

At present I finish my PhD thesis on OCL to XPath transformation. I’m trying to prove its correctness using Isabelle HOL.

Experience

March 2013 – Present

Expert of the modelling methodology group

Integrated information system of the Eurasian Economic Union (EAEU)

I participated as a methodologist in one of the largest integration projects in the ex-USSR - Integrated information system of the EAEU. The essence of the project is to simplify the information exchange between authorities of EAEU member states. Over one hundred cross-border common processes were identified. For each process, it was necessary to develop legal normative documentation and implement it in code. The volumes of the documents were to be tens of thousands of pages and a dozen companies had to develop and implement them.

During R&D, we analyzed similar projects (UN/CEFACT, NIEM, WCO DM, etc.) and proposed to develop a methodology for modelling common processes and structures of electronic documents. In a very truncated form it was adopted by the Decision No 63 of the College of the Eurasian Economic Commission at 09.06.2015 “On Methodology of analysis, harmonization and description of common processes under the Eurasian Economic Union”. I developed a part of the methodology and an UML profile (with hundreds of OCL constraints) for the methodology. More than a hundred analysts from a dozen companies in accordance with this methodology developed UML models.

UML models were uploaded into the model repository (eomi.eaeunion.org), in which the normative documents for processes and XML schemas were generated. I participated in the development of the repository as a system analyst. Also, as a business analyst, I participated in the design of some common processes and structures of electronic documents, mainly in the areas of intellectual property, transport control, sanitary and veterinary control, drug circulation, etc.

Also, I trained analysts of UML, OCL, BPMN, XSD, etc., advised them on modelling issues, and controlled the modelling quality. I developed plugins for Rational Software Architect Designer to simplify the work of analysts.

I participated in writing the “Methodology for the development, maintenance and use of code lists and classifiers that are part of the unified system of normative and reference information of the EAEU” (not yet approved). Analyzed code lists used in the EAEU member states, developed some harmonized code lists.

Improved analogue of SWIFT MyStandards for The Central Bank of the Russian Federation

This was my second major project in this company. The Bank of Russia decided to use ISO 20022 for financial messages. One of the main drawbacks of ISO 20022 is that it does not offer a mechanism for formal description of message validation rules. Usually rules are described in natural language and then implemented manually in programming language. We proposed to describe these rules on the formal Object Constraint Language (OCL) and then generate XSLT, Java, and other implementations for the required platforms. This allows one to completely exclude developers from the process of rule development and save significant resources. The idea is mentioned in the Bank of Russia Standard STO BR NPS-1.0-2017 “Financial messages in the NPS. General terms”.

I proposed the idea and developed the translator from UML models with OCL constraints to XSLT or Java code with XPath expressions. I participated as a system analyst in the development of the entire system, wrote technical documentation, assigned tasks for developers.

I wrote a number of articles on the subject of both projects (see Publications section below).

Aug. 2008 – Feb. 2013, Bonum (one of the largest children rehabilitation centers in Russia)

Lead C# developer and project manager

Medical information system

At the time the work began, Bonum already used a number of disparate accounting systems based on FoxPro, MS Access, Delphi. We developed a single database for them (MS SQL), a single engine (C#, DevExpress), transferred most of the existing accounting systems to a new engine, developed a number of new subsystems.

The following modules were implemented: polyclinic, hospital, paid services (cosmetology, stomatology), electronic health record, laboratory, sick list, situational center, contact center, science, publications, HR, purchases, PACS (DCM4CHEE), analytics (SSAS).

I also automated the formation of most of the reporting using OLAP. I implemented OLAP cubes for ambulatory, hospital, and medical follow-up.

Analytical work

I modelled business processes (BPMN, IDEFX, Signavio Oryx, EleWise ELMA):

I helped doctors with statistical data analysis in their dissertation research (SPSS, Statistica, self-written plugin using Excel-DNA).

Also

I developed and maintained information kiosks (C#, WPF) and website www.bonum.info (PHP, Drupal, HTML, CSS). It worked successfully for several years. Unfortunately, now the company lacks its own web-developers, so the site was replaced by a typical solution: with pictures of 200px wide on the screen and 5Mb in size, without forum, etc.

I initiated and leaded the project on the IP telephony implementation (4 distributed offices) and the contact center creation.

I wrote several scientific articles on function cost analysis, balanced scorecard, process modelling, etc. in healthcare.

July 2007 – June 2012, Ural Federal University

Teacher on business process modelling

Jan. 2000 – Dec. 2015, Freelance occasionally

Web developer

I developed and maintained several web-sites. The most interesting project was a news portal of ITAR-TASS Ural. For more than 10 years, it has been a fairly powerful news portal, now it has been combined with the main ITAR-TASS portal. I have a deep understanding of PHP, HTML, CSS, MySQL, JavaScript, Drupal.

Education

Certificate of professional development on venture capital financing

2017, DataCamp
