What I'm looking for

I seek backend or cloud-focused roles where I can build scalable Java services, optimize databases, and automate reliable AWS infrastructure within a collaborative, performance-driven team.

I am a senior backend developer with nearly 8 years of commercial experience building scalable Java services, optimizing databases, and automating cloud infrastructure. I currently develop high-quality code and automate AWS infrastructure at Sonar in Geneva.

My background includes contributing to high-load banking systems at Tinkoff and large-scale retail projects at Magnit, where I worked across the full SDLC, implemented REST APIs, and performed PL/SQL and schema optimization. I have hands-on experience with Java 17/21, Spring, Micronaut, Oracle, PostgreSQL, and NoSQL databases.

I prioritize reliable infrastructure and efficient deployments, having managed AWS services (RDS, DynamoDB, Lambda, ECS, SQS, SNS, EventBridge), built CI/CD pipelines with GitHub Actions, and supported IaC and legacy Python services. I bring a pragmatic, performance-focused approach to backend engineering.
