Software Integration & Verification Engineer

NOKIA
JUNE 2020 - PRESENT

Works as an Integration & Verification Engineer in product or technology program under Agile SW development. Accountable for quality, accuracy, and timely delivery of own output. Responsible for his contribution to the success of the SW development team through teamwork and high quality of performance.

  • Analyzing system concepts and complex product and system features,
  • Performs activities in SW development verification including, but not limited to:
    Feature Testing, Regression Testing, Performance Testing and Stability Testing,
  • Test planning, test case design and test case coding
    (including effort estimation and work planning),
  • Test environment planning, building, integration and maintenance,
  • Creates automated test suites and scripts for the product,
  • Reporting test results into tools and generation of test reports,
  • Writing defect reports and verifying corrections,
  • Collaboration with the stake holders (system specification team & SW developers)
    and support to other testers and developers,
  • Review requirements and participates on the early stages of specification creation, provide specification solutions based on the current code,

Deputy Manager of Electronic Assembly Department

EBS INK-JET SYSTEMS POLAND
OCTOBER 2019 - JUNE 2020

Being Deputy Manager of Electronic Assembly Department I perform the duties of a manager during his absence. Additionally I respond to synchronization of technological and production operations, controlling the production plan in consultation with the main manager. In addition at my work I deal with:

  • monitoring of reflow and THT soldering processes,
  • monitoring of production statuses and proper response to occuring irregularities,
  • creating testers and technological equipment to streamline production along with full documentation,
  • training and deployment of new employees

Electronics Test Engineer

EBS INK-JET SYSTEMS POLAND
OCTOBER 2017 - OCTOBER 2019

Being Electronics Test Engineer I participate in the design and implementation of production testers. I create workplace instructions and documentation for testing electronics components in cooperation with the construction department. In addition, at my work I deal with:

  • Installing the proper software versions,
  • Conducting functional tests and measurements of selected components,
  • Localizing the damage and the repairing of electronics components,
  • Analysis of damage causes and their elimination from the production process,
  • Keeping of damage statistics

Education

ACADEMIC CAREER

MASTER DEGREE IN SCIENCE

UNIVERSITY OF SCIENCE AND TECHNOLOGY IN WROCŁAW
FACULTY: MICROSYSTEM ELECTRONICS AND PHOTONICS
SUBJECT: ELECTRONICS AND TELECOMMUNICATION
Studies realized in English
GRADUATED IN 2017
Thesis title:
"Comparison of the effect of temperature on the parameters of optoelectronics MSM photodetector constructed on different types of AIIIBV layers"
The purpose of this work was to dermine the dependence of temperature effect on the MSM photodetector parameters contructed on different types of AIIIBV layers.
There are three basic parts of the diploma thesis: a theoretical analysis including the description of light absorption and AIIIBV materials, the temperature influence on specific semiconductors parameters and Schottky barrier height of metal - semiconductor junction. The first part of diploma thesis include also the description of the MSM photodetector along with its basic parameters. The next part describes the measurement setup, the measurement methodology and the tested structures. The final part of the work is the presentation, analysis and interpretation of the obtained measurements and results.

ELECTRONICS ENGINEER

UNIVERSITY OF SCIENCE AND TECHNOLOGY IN WROCŁAW
FACULTY: MICROSYSTEM ELECTRONICS AND PHOTONICS
SUBJECT: ELECTRONICS AND TELECOMMUNICATION
GRADUATED IN 2016
Thesis title:
"Design of technology of ohmic contacts to n-type InGaAs layers"
The contact pads are performed from various metals with appropriate properties. When designing and producing a device, a series of measurements, experiments should be made. The question is how to improve specific parameters. The optimal implementation of the technological process of creating ohmic contacts is time-consuming and difficult to perform. Improving one parameter it is possible to deteriorate another one. In the first part of diploma thesis InGaAs semiconductor is described. Its material properties and applications in today's electronics. Next part describes electrical parameters of ohmic contacts with short description of how to measure it. The definition of the specific contact resistivity ρc and the TLM (Transmission Line Measurement) method of measuring the test structures will be given. Next chapter presents the method of test structure preparation and how technical parameters (metal type, temperature, time of the heating process) influence on the quality of contact. The final part of the work is the presentation, analysis and interpretation of the obtained measurements and results.

FRONTEND

SELF-EDUCATION & HOBBY

I am a creative person who likes to play the piano or guitar in my free time. The thing that connects the scientist mind with the artistic soul is frontend development! The possibility of creating certain forms, shapes, giving them colors and animations while maintaining programming logic. This is why frontend is my hobby!

  • Good knowledge of programming: JavaScript (ES6), jQuery
  • Good knowledge of technology and tools: HMTL5, CSS3, SCSS/Sass, Bootstrap
  • Basic knowledge of AJAX and RESTful API
  • Understanding of Single Page Application and Responsive Web Design
  • Basic knowledge of React, Redux, npm, Webpack, Babel, Git, GitHub, Node.js, Express, MongoDB
