• Software Developer, Validately (Acquired by UserZoom)

  Jun, 2016 - Jun, 20193 years

  In my role as a Full-Stack Software Developer, I was responsible for developing critical applications. Some of the key projects I led include:

  The design and execution of a remote moderated UX testing tool, employing a React-based frontend, Express/Socket.io driven backend, and a Google Chrome Extension, all written in TypeScript. Praised by both management and customers for reducing the number of unresolved issues, I worked solo on the project before later creating a collaborative team to maintain and extend the functionality of the solution. Our tech stack included Webrtc, TypeScript, Node.js, Express, Socket.io, React, Redux, and Google Cloud Platform.

  Another highlight was the design and creation of an unmoderated UX testing tool, which was a Google Chrome Extension featuring screen recording capabilities. Technologies deployed for the project were TypeScript, MediaRecorder, Node.js, Express, and ffmpeg.

  Additionally, I contributed to various smaller scales yet significant projects, such as the internal logic routing system and the admin dashboard.

• Software Developer, Orbis Investment Advisory Limited

  Aug, 2013 - Sep, 20152 years 1 month

  As a Software Developer at the Quantitative Analysis Department of Orbis Investment Advisory Limited Mutual Fund, I was part of multiple transformative projects.

  Took the lead in designing and implementing a sophisticated analysis tool for quantitative analysts. This tool, used for the backtesting and valuation of alpha models during portfolio construction, was based on Reactive (Rx) and Dataflow Programming principles. Operating as the singular developer in a team of four, the tool was positively received, becoming the primary tool for several analysts.

  In another project, I developed a tool for Portfolio Managers to efficiently manage their portfolios' cash flows. This was a C# application with a WPF user interface and a WCF backend service connected to SQL Server. As the lead implementer in a three-member team, we were able to greatly improve the daily workflow of Portfolio Managers.

  Contributed significantly to the development of a research tool used to identify and gauge the performance of various market themes based on complex user-defined criteria. This was a collaborative project in a team of five.

  Regularly verified and optimized numerous financial models developed by quantitative analysts, using SQL, Matlab, and R.

  Offered reliable support for aged legacy software, primarily developed in Visual Basic 6 and SQL.

• Software Programmer, University of Warsaw

  Oct, 2010 - May, 20121 year 7 months

  As an active participant in the Synat research project, funded by the National Research and Development Center's strategic programme, my contributions were several-fold:

  For my master's thesis, I developed an innovative semantic faceted search engine. This project was meticulously executed using Python and C#, with a PostgreSQL database at its core.

  I co-authored a relational database schema, designed for the efficient storage and query of parsed scientific articles, further enhancing our project's scope.

  I was also involved in gathering, parsing, and preprocessing of scientific data derived from a multitude of sources, playing a key role in data management and understanding.
