I’m a software engineer with over 20 years of experience, including 10+ years with Kotlin and JVM technologies.
Kotlin/JVM tooling, rendering systems, and data and asset processing pipelines.
I created and led KorGE and its Korlibs ecosystem, building modular libraries, Gradle tooling, graphics, media, I/O, serialization, dependency injection, and multiplatform production workflows.
I turn algorithmic and math-heavy problems into maintainable, tested software, and I am looking for a permanent employee role in Spain where I can contribute to one product and team over the long term.
Delivered product-engineering work using Kotlin, TypeScript, Kotlin Multiplatform, CI, testing, and observability. Engagements covered cross-platform rendering, architecture simplification, developer experience, technical mentoring, and end-to-end delivery within the client teams. In a standalone project, deployed a backend with AWS Elastic Beanstalk, used Amazon RDS for the database, ElastiCache for Redis, and Elasticsearch for logs, and delivered static assets through Amazon S3 and CloudFront.

GTAHUB
Principal Engineer · Exclusive contractor
Halved compilation times, enabled full IDE debugging, introduced Datadog and PostHog observability, added traceability for server events and performance problems, simplified build workflows and architecture, and versioned game configuration across multiple servers. Progressively migrated both the Node.js backend and Vue 3 web application from JavaScript to TypeScript, introduced Kotlin coroutines, and documented and taught the resulting practices to the team.
Cut compilation times by 50%, enabled IDE debugging, and mentored developers in Kotlin coroutines
Outcome: Greater team autonomy and faster feature delivery.
