Technical AssignmentThere is a file with a sequence consisting only of 0 and 1.It is necessary to analyze this sequence and try to find any patterns that will allow predicting the next symbol better than random guessing.At the same time, the task is not to learn to predict each subsequent symbol. If it turns out that this is impossible, it is sufficient to find such repeating patterns or states of the sequence after which the probability of the next symbol is significantly higher than 50%.For example, if after a certain combination of symbols the next symbol is equal to 1 in 70–80% of cases, then such a pattern is already of interest, even if it occurs not very often.The main task is to find any patterns that can be used to achieve a positive mathematical expectation.The evaluation rules are very simple:correct prediction — +1 point;incorrect prediction — −1 point.The ultimate goal is to build a model or find a rule that will have a positive mathematical expectation over the long term, meaning the sum of correct predictions should exceed the sum of incorrect ones.The performer independently chooses the research methods. These can be statistical methods, searching for repeating patterns, machine learning, neural networks, or any other approaches. It is not necessary to limit oneself to standard methods — any ideas that can help discover patterns are welcome.As a result of the work, it is necessary to provide:a description of the found patterns (if any);a description of the methods used;results of testing the model or found patterns;prediction accuracy;final result according to the evaluation system (+1 for correct prediction, -1 for incorrect);source code of the research.

C# / .NET WPF Developer – Completion of Migration of a Large Invoicing Program RAFSOFT.NET Sp. z o.o. is looking for a C# / .NET developer to complete the rewriting of a large, long-standing invoicing program to a new technology.

Scope of Work: completion of the migration of a large desktop application to C# / .NET, recreation of the functionality of the old program in the new version, maintaining as identical logic of operation, appearance, and handling as possible, working with DevExpress components, analyzing existing code and comparing the operation of the old and new versions of the program, fixing bugs, completing missing functions, and testing the application, collaborating on the final preparation of the program for deployment. Requirements: very good knowledge of C# and .NET, experience in creating desktop applications for Windows, knowledge of WPF or WinForms, experience with DevExpress or similar UI component libraries, ability to analyze a large existing project, accuracy and patience in reproducing existing functionality, ability to test one's own changes, very good ability to use AI tools supporting programming, code analysis, refactoring, and testing. Preferred: experience with legacy projects, knowledge of or previous work with Visual Basic 6.0, experience in migrating applications from older technologies to C# / .NET, knowledge of issues related to invoicing, accounting, JPK, or KSeF, experience working with large business applications. Who We Are Looking For: We are looking for a self-sufficient, precise, and technically experienced person who can enter an existing project, understand its logic, and consistently bring it to completion. In this project, it is very important not only to write new code but also to faithfully reproduce the operation of the old program — both in terms of functionality and appearance as well as handling. We also require proficiency in using AI tools in daily programming work. We are looking for someone who can use AI practically: for code analysis, bug finding, speeding up migration, creating tests, and organizing the project.

Project Meta Implement Viber integration without using third-party CRM systems. All work with messages should be done directly in our internal CRM based on BAS / 1C 8.3.Current System BAS / 1C 8.3 Custom configuration "Customer Service" Database of over 40,000 subscribersRequired Implementation Integration through an official Viber Business provider (TurboSMS, GMS Worldwide, or another agreed service). The button "Write to Viber" in the subscriber card. Sending messages directly from BAS. Receiving incoming messages via Webhook. Automatic linking of messages to the subscriber by phone number. Complete preservation of correspondence history in the subscriber card. Displaying the time, message status, and the manager who responded. Simultaneous work of multiple managers. Message templates for quick responses. Assistance with setting up the Viber provider, API keys, and Webhook. Transfer of all source code and settings after the work is completed.Acceptance Conditions The work is considered completed after successful testing of all functions on the working database and transfer of the source code.Guarantee 1 month warranty for fixing bugs related to the implemented functionality. Further modifications are carried out by separate agreement.Result After the project is completed, managers should be able to fully work with Viber directly in BAS: write to clients, receive responses, view correspondence history, and communicate without using third-party CRMs. All source code, modifications, API keys, and settings will be transferred to the client after the project is completed.
