Projects:1. Services for verifications:• Development and support of flow verificationsTechnologies: Golang, PostgreSQL, Redis, Docker, Kubernetes

Projects:1. Service for A/B testing: • Implemented the trust metric for A/B tests • Improved performance sampling data (validation, algorithm, queries) in average from 30 s. to 5 s. • Optimized site tree building (validation, algorithm, queries). Reduced time by about 2-5 times2. Elements constructor for website: • Implemented the notification system for first setup of script to client website • Implemented collector of elements errors on… Show more Projects:1.

Projects:1. Anti-fraud service: • Created a subsystem for customer risk assessment - client scoring • Optimized data lake (structure, queries, indexes) and reduce average response time from 100 s. to 2 s. • Improved performance (restructuring, partitioning, indexes) of several critical SQL-queries in 2-6 times • Implemented point blocking of the client • Wrote a library for checking status of all necessary external servicesTechnologies: Python,… Show more Projects:1.

Service for calculation client scoring - risk assessment: • Designed all necessary components of system • Implemented some components of system (adapters, caching, workers, API) • Implemented deferred and batch work for heavy data processing • Integrated service with anti-fraudTechnologies: Python, aiohttp, RabbitMQ, Redis, PostgreSQL, Kafka, Docker, Docker-compose Show less

Projects:1. “SCEF” (Service Capability Exposure Function): • Implemented python script for convenient separating tests logs • Added new features in custom library for testing • Created new functional tests for new product featuresTechnologies: Python, Bash, Robot Framework, pytest, Docker, Ansible
