Developed a Python test automation framework from scratch for the Tatango web interface and ported all tests from the previous JavaScript framework. I extended the test framework to simultaneously test the old web interface in production, the new web interface, the internal API, and the external public API.

Performed the test automation of the machine learning toolkit, which is a part of Alteryx Designer, the Windows desktop software for data science. I used Python, Selenium in CEF mode, and pywinauto for automation. During six months, I built a test suite of more than 200 complex end-to-end test cases from scratch, with an execution time of over 10 hours.

As a software developer, I constructed a Python framework to fulfill the need for the integration and component testing of ROM and RAM applications, with the added complication of CPUs being from multiple vendors.

Test framework details included:
• Server – The issue was that all vendors used a different communication protocol, and usually, only 2 – 3 FPGA boards were available for chip simulations for a team of 10 engineers. I developed a separate server for each vendor. Most servers were written in Python, but some required vendor-specific languages, such as Tcl.
• Test base – Having one suite of test cases and libraries for all vendors and chip types enabled us to perform the same scenario slightly differently if necessary.
• Runner – This was based on keywords assigned to each test case. The run configuration was collecting an appropriate list of tests to run for a given vendor, chip type (simulated or real), and application. It also included or excluded some logical groups of tests, such as those for real chips, while destructive tests were excluded by default. The runner was written as a plugin for nose tests, support, and test reports for a MySQL database.

I used Python, nose, MySQL, and Tcl on this project.

Working as a QA test automation engineer, I developed a test framework in Python to test macOS X desktop applications. I also developed scripts to test two Egnyte applications. One was made to synchronize files with the cloud, and the second, the more advanced one, was supposed to give users the impression that they were editing files directly on the cloud. Both applications were configurable via a web interface.

For the automation of the testing process, this framework provides all the tools to install and uninstall a tested app using AppleScript, configure it using Selenium, and manipulate and generate different types of files. The framework also simulates user experience working with the most popular desktop apps, such as Microsoft Word, Excel, PowerPoint, and Adobe Photoshop. This way, we can properly test how these applications deal with files in the cloud.

I used Python, Selenium, and AppleScript on this project.

Working as an integration engineer on this project, I developed a Bash script to generate JSON configuration files and deploy them together with software into multiple data servers.

The script can be logically divided into two parts:
• Configuration – The service transforms multiple types of configuration files. The validation schema fulfills the requirements for six different STB models for four types of environments in six countries. Each of them supports 3 – 8 different variants for a specific group of customers, dealing with several top-level real-time configuration parameters.
• Deployment – This script needed to cope with the configuration files and software in specific locations, validating if the files hadn't been corrupted.

I used Bash, sed, AWK, jq, JSON, and Secure Copy Protocol (SCP) on this project.

This project aimed to design and produce a series of vandal-proof vending machines that sold candles located in graveyards.

On this project, I was the company owner and primarily responsible for project and line management. I also took part in the functional design process and graphic design. We bought old Coca-Cola vending machines from the US, importing them to Poland via a German company (it was still cheaper to do that than buy directly in Poland). We then removed all the old electronics and replaced the mainboard, coin, and bill selectors with those manufactured by the Taiwanese company ITC. We integrated it with a designed module for battery power and the rest of the existing mechanical parts.

The last phase involved designing and producing the armor to make the machines as vandal and environment-proof as possible and creating the marketing and graphic design, which I did by myself, to make the machines look great.

For my master's thesis, I developed software for the semantic analysis of the content in PDF publications written in English. The software was written in Python using the Natural Language Toolkit (NLTK) library and Qt library for the user interface.

TECHNOLOGIES
Python, NLTK, and Qt.

As a part of my internship as an electronic designer, I designed and developed a device measuring the intensity of light and sending the results to the multimeter via RS232.

TECHNOLOGIES
C, Assembly, and Eagle.

The code that enables you to interpret received and expected responses to provide pertinent information when an assertion fails.

This project's complexity was related to the fact that communication with different devices was done through the same protocol, but the same value for status messages had other meanings. This function allows you to interpret the status message correctly depending on which communication class was used.
