Опыт работы
- backend go developerИюль 2022 — Январь 2023 (7 месяцев)
• Developing and debugging services.
• Supporting and monitoring existing microservices.
PostgreSQL • Golang • Kubernetes • Apache Kafka • Grafana • GitLab • gRPC • Graylog • Jira - Skyrex (OOO Иммерсиум)МоскваPython Backend developerИюнь 2020 — Январь 2022 (1 год и 8 месяцев)
• Prototyped and developed from scratch processing of complex deals interacting with stock.
• Optimised requests to external API’s by caching system which allowed to double number of users.
• Implemented from scratch custom accounts managing system and administration tools.
• Migrated from raw SQL to ORM and migrated from Flask to FastAPI, to speed up delivery.
• Improved performance of services using asynchronous approach (FastAPI) by 30%.• Rewrote application to 4 services from monolith for easy scaling and distribution.
• Designed and implemented architectural solution that helped to expand potential customers in 10 times.
• Developed tools and scripts for tracking health of services, that decreased problem-solving time.
Tools: Python3.8 ( Flask, FastAPI, Aiohttp, SqlAlchemy ORM, Aiogram, Alembic, SQLite, RabbitMQ )
