Key Achievements:● Developed a universal connector for interaction with managed systems. The interaction is configured using a flexible configuration and is carried out by a technical support service. This completely freed developers from the need to create and configure separate connectors for each of the integrated systems● Developed a universal mock service for testing and debugging the universal connector. The mock service allows you to simulate the behaviour of managed systems and is flexibly configured. This removes the need to wait for the appearance of a real API and debug in accordance with the agreed specification. It also facilitates the work of QA engineers, saving them from manually simulating responses from managed systems● Developed a universal data loader for managed systems that do not have an API. It accepts excel files with data in a consistent format, parses them and saves them to the system. This completely freed developers from the need to create separate data loaders for each of the integrated systems and liberated technical support services from the need to manually load data. ● Developed an open segment of the system that allows you to access publicly available data outside the company network. It is based on the same software as in the closed segment but here it doesn't operate with private data. This allowed top management to view reports and requests outside the company network● Ensured proper documentation was recorded for all developed features

Key Achievements:● Decompiled artefacts and brought the codebase of the project into working condition, since the previous vendor did not transfer the source codes● Integrated the Portal of Moscow Government with the services of a Single Personal Account and a Multiservice Сentre Providing State Services for the purpose of exchanging the personal data of users

Key Achievements:● Assessed the main functionality with selenium tests, which made it possible to reduce the labour costs of QA engineers

Key Achievements:● Developed incorporate Android application for the review of individual development plans and vacations● Developed backend service for the mobile application● Developed Interactive Voice Menu to inform customers of their financial statement using IVR Avaya Orchestration Designer technology
