Senior🎓
Top SchoolOlha Shekera is a Senior Scala Engineer with 11 years of experience building high-performance, scalable systems using Scala and Java across cloud and stream-processing stacks. She has repeatedly improved throughput and reliability—e.g., moving notification services to event-driven architectures to boost capacity 2.5x and designing a failover engine for critical data layers. Her background spans big data and real-time processing (Flink), microservices frameworks (Play, Quarkus), and AWS-backed platforms, with hands-on experience accelerating map delivery and automated report analysis. She has led small teams and driven cross-functional projects from Netcracker to Intellias, blending algorithmic rigor and practical system design. Notably, she pairs a perfect master’s GPA in Software Systems with a knack for inventing bespoke tooling (MongoDB versioning/migration and dynamic query constructors) that reduced testing and analytics time by multiple factors. Based in Kyiv, she combines deep technical craft with a focus on measurable performance and operational resilience.
