•Strong testing discipline, including Jest unit tests, integration tests with real databases, and microservice testing
•Security-conscious approach to code that may handle real user funds
•Skilled in technical research, evaluating trade-offs, testing hypotheses, and making data-driven architectural decisions
•English proficiency at Upper-Intermediate
•Fluent in Russian
•Technically strong, with an architectural mindset and the ability to consider data flows, failure modes, and long-term maintainability
•Able to defend technical decisions and explain trade-offs to engineers and stakeholders
