Alex Guppy
Mariusz is a strong lead developer who cares about the quality of the product with a long-term view for the business. He has detailed business experience with Swaps/Bonds RFQ flow, along with his technical experience. He will notice the smallest details on GUI design and recommend features in ways that are not always expected but often welcomed. Good fun to work with and hope to work together again soon.

Mariusz is a very talented Agile developer who has a wealth of experience in the industry. He has worked as a contractor for me and his attitude and commitment have been exceptional. Mariusz was initially taken on as a senior agile developer but when we lost the Technical architect, Mariusz stepped in and took the reins with a commitment that is rare to see in a contractor. Mariusz is a great team player and injects some great humour and team work into the team. I would definitely recommend him to work with.

Project: Orion – A Risk and P&L analysis and aggregation tool. (WPF 4.0, DevExpress)Orion is a reporting tool used by users from Rates, Exotics and Hybrids in front office, middle office and product control. Currently we are also taking the Flow business and the DCU desk on board. It provides:- Fast server-side slice and dice operations on very large data sets,- Management of workflow between Front, Middle Office and Product Control,- Flexible design to allow new reports and data sources to be quickly added,- High level of visibility linking data availability to report status.When I joined the Orion developers’ team, the Orion user interface was written in WinForms and CAB. Since then I have not only migrated existing functionalities to WPF and MEF, but also I have introduced many new features. I have been working closely with Orion users to recognise and gather any new requirements, necessary to implement the desired functionalities. To develop new graphical user interface I have used MVVM and TDD patterns. To ensure that the GUI, during long-running operations, is always responsive, I have also used task parallel library. I have taken the full advantage of third party components created by DevExpress. • Achievements/Improvements made: WPF (4.0), DevExpress WPF controls(Pivot Grid, Data Grid, Docking and Layout Controls, Bar Manager, Charting), MEF, TPL, Expression Blend, Memory Profiler, Performance Profiler, Coherence (POF), Fitnesse.

Old legacy server side component was rewritten using DDD and SOA architecture which provide stateless WCF services. During that time I was also involved in mentoring developers by helping them to better understand Agile and TDD, showing more efficient ways of writing a code (Design Patterns, Refactoring etc). I was also responsible for the design and implementation of the High Availability architecture, which had a SQL Cluster, load balanced application layer serviced by a distributed application cluster to provide automatic fail over to disaster recovery side.• Achievements/Improvements made: WCF, DDD, TTD, SOA, MS SQL 2008, Windows Forms, TFS, Design Patterns.
