Functions:• team management,• development of the department and partially company strategies,• project development planning,• maintaining critical infrastructure,• software development.Results:• As part of a participation in the architectural department, made a significant contribution to identifying problems with existing systems and developing an architecture of the single company platform.• Plans for the development and stabilization of critical projects have been developed and partially implemented.• Some of the problematic legacy systems have been transferred to a modern tech. stack and architecture. For the exchange data aggregationsystem, this allowed to reduce the time to search for errors in the data from 1-1.5 days to several minutes, as well as significantly reduce the number of system failures.• Detailed documentation has been written for legacy projects.• All the services of the department were found, most of the accesses were restored and detailed diagrams of the systems were built.• Employees who sabotaged teams against past managers were identified and fired.• Friendly and working relations were established with neighboring departments, which deteriorated due to the previous turnover of managers.• Simplified Scrum, KPI metrics and SLA were implemented, also non-toxic working relationships were built within the department.• Clear areas of responsibility for shared projects with other departments have been identified.• The department's focus has shifted to AI. Research was conducted and technical specifications were developed for the first pilot projects.• The areas of responsibility within the department were reallocated in order to eliminate the repeated loss of expertise on projects in the future.Tech. stack:Python, C, JS, TS, Node.js, Django, Asyncio, Ansible, Docker, LXC, ArgoCD, Kubernetes, ChatGPT API, Exchange FAST/FIX/REST API, ELK, PostgreSQL, ORACLE, MongoDB, Bitbucket, Gitlab, Jira, TeamCity, Confluence, UML, C4.

Functions:• assistance in the analysis of project requirements,• researches, • tech. calls with clients,• partial team management,• CI/CD implementation,• software development,• code review,• mentoring.Results:• Became a lead developer on a system for the IFRS 17 standard from the development of an MVP project to the provision of customer support services [Azure, Azure DevOps, Python, TypeScript, Angular, Vue.JS, Node.js, PostgreSQL, Oracle, Flask, Pandas, Numpy, SonarQube].• Communicated with clients.• As part of the research on how to speed up our mathematical engine for calculating IFRS 17 reports, together with actuaries, built a complete formal mathematical model of the engine.• Developed a fuzzy logic parser to analyze debit card transactions [Rust].• Developed a mobile operator DWH analyzer. The client wanted to see the graph of their database, identify internal data flows, as well as irrelevant or unnormalized parts of the database schema. However, the system did not have a test circuit, the storage volume was more than 2 Pb, and all the data processing logic was written in stored procedures, which required non-trivial solutions [Java, Oracle, Matplot].• Conducted research on the possibility of developing a digital double [TS, C++, Node.js].• Developed a documentation classifier based on the LSTM model [Python, Keras].

Functions:• software development.Results:• Designed and developed a business process management system from scratch [C#, ASP.Net, MS SQL Server].• Improved the SMEV 3-based bus [Java, SMEV v3].• Designed and partially developed an Android client for the Olympic Reserves platform [Java, Android].
