I build scalable Java and Kotlin microservices for customer-facing products and distributed ledger applications.
What I'm looking for
I'm building scalable Java 21+ services and RESTful APIs at simpleshow, helping users worldwide create customized explanatory videos from text scripts.
I work daily with Spring Boot, Hibernate, MySQL, Postgres, DynamoDB, Elasticsearch, Redis, and Kafka to support event-driven services. I also deploy and maintain containerized services with Docker and Kubernetes, backed by unit and integration tests.
Previously at INDUSTRIA, I designed distributed ledger applications with Corda and built Kotlin, Spring Boot, and Kafka microservices for enterprise-focused deeptech work. I contributed through code reviews, Agile delivery, and close collaboration with product owners, designers, QA, and developers.
I've also co-founded CareerHub, where I owned the development process, built the backend, guided frontend delivery, and handled AWS deployment and architecture decisions.
