Мои компетенции и опыт

I am a Backend Developer with 3+ years of experience. While the majority of my career has focused on Java backend development, I am also highly interested in Python or Go. I can design, code and deploy a service either alone or as part of a team. Have experience maintaining Linux servers, both in personal and professional scope. I also contribute to open-source projects whenever possible.

I have strong knowledge with: Java, Golang, Python, microservices, Spring Boot, Postgresql, Oracle

Projects i participated:

SaluteBot IDE, Sberdevices - IDE for chat-bots

• Optimized chat-bot dialog journals - time to obtain a journal decreased from few minutes to few milliseconds
  Journal subsystem was migrated from PostgreSQL to ClickHouse
• Implemented a conversion report - now chat-bots developers can see bottleneck of scenarios
• Integrated a AI agent system to chat-bot scenario - now AI-agents can solve some out-of-scenario cases
• Spring boot updates, solving hibernate N+1 problems, solving memory leaks, Gitlab pipelines, etc

Ariadna MIS, Reshenie - Medical information system

• Implemented updater-tool for PostgreSQL databases with 10000+ stored PL/SQL procedures - time to update system for one client decreased from one day to one hour.
• Redesigned CI pipelines, migrated CI pipelines to Jenkins, implement custom CI Maven plugin - build process was significantly simplified, got rid of any "secret knowelege".
• Implemented digital signature service - now medical employees can sign documents without physical keys attached to their computers.
• Implemented or supported external system integrations - using REST, SOAP or even FHIR 4. Often with digital signing of messages.
• Solved client problems "in place" - sometimes speaking directly with client technical teams.
• Written technical documentations for support teams.
