I'm the sole Backend Engineer at CodyUA, building a greenfield FinTech analytics platform with Java 21, Spring Boot, GCP, PostgreSQL, LangChain, and LangGraph. I own architecture, cloud setup, REST APIs, automated testing, and AI-driven data-analysis workflows.

I've delivered high-load distributed services at Favbet Tech, improving observability with ELK and DataDog, resolving performance bottlenecks, and helping maintain 99.9% availability. At SPD Technologies, I built analytics-platform infrastructure, created a Kafka producer tool that accelerated QA cycles by 40%, and streamlined delivery with GitLab CI and Terraform.

My background includes core banking services at Intellias, a modern HR platform for thousands of users at Ciklum, and a workbook platform for testing ML models at NIX Solutions. I also helped build a floral e-commerce platform from scratch, spanning Spring backend services and SEO-friendly React and Next.js interfaces.

I enjoy simplifying complex problems into effective parts, designing durable software architecture, and applying AI where it creates practical product value.
