PROJECTS
Project 1: Web crawler on a specific topic

Description: The following methods were used to implement the task: width search for all internal links on each web
page, search using robots.txt and sitemap.xml files. The list of websites to be processed was obtained using the Google
Custom Search API, data from the database for previously processed websites, and an external file provided by the user.
A headless browser and round-robin algorithm were used to avoid blocking.
Responsibilities:
Create a script to automatically search for websites on a given topic using the Google Custom Search API.
For each website found, utilize a headless browser and round-robin algorithm to avoid server blocking during
scraping.
Download and save the content of all available pages on the website to the database for further analysis using AI.
Implement search using robots.txt and sitemap.xml files for comprehensive data collection.
Containerize the entire scraping process for scalability and portability.
Technology stack:
Ruby, Docker, Docker-compose, Google Custom Search API, MySQL, bash scripts, CLI, Chromium, Nokogiri
 Project 2: Parsing all available information from courtlistener.com
Description:
My task involved parsing and saving 60 million unique dockets to the database efficiently. Despite limitations in API
pagination, I developed a query logic to cover all available data without loss. After discovering a potential solution
involving bulk data downloads, I coordinated with the website development team, leading to a resolution within 1-2
months and allowing for efficient processing of the 180 GB csv file once updated information became available.
Responsibilities:
Developed script to parse and save 60 million unique dockets to the database efficiently.
Implemented automatic weekly document downloads from the site.
Analyzed API filtering system and devised query logic to cover all available data.
Discovered possibility of bulk data download, initiated dialogue with website development team to resume monthly
database dump updates.
Conducted additional research to optimize parsing script.
Technology stack:
CSV, REST API, MySQL.

Project 3: WatchDog
Description:
The project aimed to address data loss incidents in a shared MySQL database by developing a script to monitor
database structure changes. The script, accessing an "approved data schema" and responsible personnel list via
corporate website API requests, notified relevant individuals of any alterations every hour. Implemented within a week,
the tool significantly reduced data loss instances, clarified workflows, and bolstered team focus on development tasks.
Responsibilities:
Developed script to track changes in database structure and generate alert notifications on Slack channel.
Utilized MySQL database; streamlined access by having all developers log in under same account.
Addressed issue of sudden data disappearances, often due to table renaming, by implementing hourly database
structure checks.
Script accessed "approved data schema" and list of responsible persons for each table through corporate website
API.
Reduced incidents of data loss by tenfold within a month, enhancing clarity of critical workflows and allowing
developers to focus on development.
Technology stack:
Ruby, REST API, Slack integration.

Project 4: Class wrapper for AWS S3 Clien to work with Amazon cloud storage.
Description:
Due to the chosen tariff plan for the cloud storage, it became necessary to develop a class wrapper and implement it in
the internal framework of the project so that developers could change the default settings of the AWS S3 client. In
addition, it was necessary to raise an exception when trying to transfer files smaller than 100 MB to the storage. This will
significantly reduce the cost of storing critical information on a third-party resource. Since this class will become part of
the enterprise framework, the Tech Lead asked that it be well documented using YARD. I successfully navigated
through the "rather confusing" AWS S3 SDK documentation, found all the methods required for the framework, and
developed and documented each of them well. In addition, I created textual documentation on the GitHub Wiki in two
languages (English and Russian). As a result, everyone in the development team was able to use the new feature thanks
to clear and understandable instructions.
Responsibilities:
Developed class wrapper to customize AWS S3 client settings within project's internal framework.
Implemented exception handling for file transfers smaller than 100 MB to reduce storage costs.
Ensured comprehensive documentation using YARD, addressing Tech Lead's requirement.
Navigated AWS S3 SDK documentation to identify required methods for the framework.
Created textual documentation in English and Russian on GitHub Wiki.
Enhanced usability for development team with clear instructions.
Technology stack:
AWS S3 SDK for Ruby, YARD, GitHub Wiki.

Project 5: Automating the verification of completed parsing tasks for the QA department
Description:
A significant number of parsing tasks had the same table structure, similar instructions, and the same algorithm for
checking by the QA team. Due to the considerable amount of manual work, checking the quality of each such task
required 4 to 6 hours of intense mental work, including vigilance and attentiveness. I proposed to develop a tool to
automate most of the same type of checks, which would reduce the workload of the QA department and speed up the
checking of this type of task by three times. This ruby script used CLI. After implementing and deploying this tool,
 all a QA team member had to do was run the script, passing it the tag number as a parameter, and 80% of the checks
were performed automatically with instant results. The QA team member could quickly review the results of the check,
make a conclusion whether everything was in order, and could focus on critical manual tests with a clear head. This tool
significantly accelerated the verification of an entire segment of tasks and had a positive impact on the QA department
as a whole.
Responsibilities:
Developed Ruby script using CLI to automate verification of parsing tasks with similar structure.
Reduced QA workload by threefold, saving 4 to 6 hours per task.
Script executed 80% of checks automatically with instant results.
Improved efficiency allowed QA team to focus on critical manual tests.
Technology stack:
CLI, REST API, MySQL.

Description:
The company transitioned to a new software package for asset accounting, necessitating database unification. However,
due to the absence of batch update functionality, manual repetition of operations was required, consuming extensive
human labor across regional centers. Despite being denied direct database access, I leveraged my computer science
expertise to develop and implement an automated clicker script, significantly expediting the task completion process
after hours. This approach enabled our branch to surpass deadlines and optimize resource allocation by minimizing
reliance on manual labor.

PRIVATE ENTREPRENEUR
Ukraine
September 2009 - June 2015

Project: Provision of consulting and related services to a team of designers in the field of water supply, drainage
and sewage systems construction

One of the most significant projects during my entrepreneurial activity was cooperation with a team of design
engineers in the field of construction of complex engineering systems and networks. This team was switching from
manual drawings to computers and needed training. Having a postgraduate diploma in computer graphics (both vector
and raster), my expertise was exactly what they needed. I have been training and supporting these specialists for a long
time, helping them to master all the intricacies of making drawings using computer technology.
In addition, as a subcontractor, I also performed some of the drawings under the supervision of these specialists. This
had 2 positive aspects: I better understood the needs of my clients and clearly saw what skills they needed to learn first,
and they could see by my example how much more efficient their work would be if they made an effort and overcame
this learning curve. A lot of positive feedback and the doubling of the design team's profitability for three quarters in a
row clearly showed that it was a very good and fruitful cooperation.
