Bohdan Antoniak

Middle Test Automation Engineer

Summary of I have 4 years of experience as a Test Automation Engineer working
Qualifications with Python and C#.

I’ve worked on UI and API automation – developing test frameworks,
writing and maintaining test scripts, optimizing code, and integrating
with CI/CD pipelines. I also created performance tests using JMeter
(including WebSocket support) and custom Java plugins, integrated with
Azure DevOps.

I have experience with SQL Server, including writing stored procedures
for data comparison between systems.

In a previous role, I wrote Python-based tests to verify FedRAMP
compliance. This involved mock HTTP/HTTPS/DNS servers, Dockerized
test environments, and validation of TLS (v1.2/1.3) and DNSSEC usage.

Most recently, I developed UI tests using Python and Playwright,
covering end-to-end scenarios, cross-browser checks, and CI integration
for continuous frontend validation.

Splunk App that collects and analyses network test results data
Project Description App for Splunk enables organizations to collect and analyze network
test results data, Event and Activity logs. Integrated with Splunk, it
provides visibility into the health and performance of IT systems,
applications, and network endpoints. The App also offers pre-built
dashboards for easy analysis. This helps operational teams monitor
performance, troubleshoot issues, and optimize both infrastructure and
end-user experiences.

Project Role Test Automation Engineer
Responsibilities • Design and develop automated test scripts to validate the
functionality of the Splunk-integrated application.
• Perform manual testing of features related to network test data,
event logs, and activity log ingestion to ensure quality before
automation.
• Build and maintain automated test frameworks and regression test
suites to ensure the reliability of dashboards and analytics features.

Fedramp certification of software that analyze networks
Project Description It is a software that analyzes the performance of local and wide area
networks, servers and applications. The product includes elements of
network tomography for loss and latency, route analytics to visualize
BGP advertisements, DNS monitoring, VoIP monitoring, website
monitoring for HTTP and HTTPS and SNMP device polling.

For Fedramp certification it is critical to ensure that software
communication with backend services is secured by Fedramp
encryption libraries, and software refuse any other non-secure
connections.

Freight/Parcel audit and payment system migration from SQL
Server to Decisions low code platform
Project Description It is a SQL Server based application for customers that allows to have
complete visibility into every detail of Freight/Parcel transportation
spend. Project was focused on migration client specific logic from SQL
Server procedures to Decisions low code platform. It decreases time of
developing client change requests, implementation of new client logic
and make customer support process more flexible.

Involvement Duration 1 year
Project Role Test Automation Engineer
Responsibilities • Analyze client specific requirements and write tests cases in Azure
DevOps.
• Perform comparison testing using SQL Server by running client
specific comparison procedures. It evaluates differences between
results of SQL Server procedures and Decisions low code platform
results.
• Maintain and develop comparison SQL Server procedures for each
new client migration.
• Analyze differences found by comparison procedures, report issues in
Azure DevOps.
• Develop client specific regression tests using C# to ensure that
already migrated logic has not been affected.

Desktop tax reporting system migration to cloud
Project Description Designed desktop program for UK tax reporting was determined to be
moved to the cloud (Azure DevOps). Testing activities were focused on
writing automated tests for Web-UI/backend parts to ensure that web-
application functionalities are the same as in designed desktop
application.

Performance tests were developed using JMeter and SiteSpeed in order
to validate performance degradation.

Web-application is designed to provide tax professionals with complete
control over the preparation and management of the end-to-end
compliance process; from the raw data collection to the completion of
the corporation tax computation, and e-filing submission.
