George Mukha

Development and implementation of all testing processes within a product consisting of 6 microservices handling financial calculations. Concurrently, I held the position of QA profession leader, where my responsibilities extended to technical practices across the entire company's QA team.

Responsibilities

• Development and implementation of functional and non-functional test scenarios
• Implementation and expansion of load testing to product teams
• Implementation of product processes and technical practices within the development department
• Development of an automated QA AI service/Development of a QA Backend service
• Release approval

Results

• Developed a QA AI service focused on writing test case scenarios, which reduced testing time from 1 week or more
• Implemented API coverage from zero to 98%, which resulted in a reduction in production errors and a 12-fold reduction in the company's regulatory fine costs
• Implemented load testing, which enabled the timely detection of over 500-times increases in request execution time and prevented SLA misses
• Automated smoke test launches based on triggers in development repositories, reducing the development team's dependence on the testing team
• Expanded the practice of load testing within the department, enabling us to understand during the development phase whether the product is capable of meeting non-functional requirements and fixing issues before production
• Implemented the 3 Amigo product practice, which reduced the number of acceptance bugs by a factor of 4

Launching all testing processes from scratch (manual and automated) within an edtech product, specifically an asynchronous educational platform. QA team: 3 people.

Responsibilities

• Developing and implementing functional test scenarios (UI, API)
• Creating a testing framework from scratch (Kotlin/Java)
• Integrating testing processes into development stages
• Approving releases

Results

• Building testing processes from scratch, improving the quality of the entire product and user satisfaction
• Implementing API coverage with automated tests from zero to 100%, reducing testing time by tens of times compared to manual testing
• Developing WEB UI automated tests for mobile devices, tablets, and personal computers, which also reduced testing time by tens of times compared to manual testing
• Led the onboarding and training of two QA trainees, resulting in each QA being promoted to junior level

Testing (manual and automated) of a mobile banking app.

Responsibilities

• Conducting regression testing of chat support and notifications
• Writing automated tests (JavaScript, TypeScript)

Development and deployment of QA backend services, ensuring the quality of the platform for high-frequency trading (HFT) in cryptocurrencies and traditional finance.

Results

• Developed a proxy service to intercept incoming and outgoing messages via FIX, gRPC, WebSocket, and HTTP protocols from the trading platform to trading exchanges. The service can modify requests/responses, simulate delays and channel blocking, and simultaneously work with multiple exchanges
• Implemented a service for creating a queue for automated tests to interact with specific exchanges to avoid cross-trading
• Developed and stabilized automated tests for market data gateways, execution gateways, and trading robots
