At Prelinko, I build REST APIs for content management, analytics, payments, and email campaigns. I also design PostgreSQL schemas and migrations, and implemented authenticated access with NextAuth v5, Prisma, and bcrypt.
At TAAN's Biobac project, I developed bank-operation import and reconciliation workflows using Spring Boot, JPA/Hibernate, and PostgreSQL. I implemented file parsing and transaction classification, and corrected account-mapping and lifecycle edge cases.
At Grid Dynamics, I designed and implemented Java 17+ and Spring Boot microservices for distributed production systems. I developed REST and gRPC APIs, added unit and integration tests, and supported Kubernetes deployments through GitHub Actions CI/CD.
My earlier work at Grid Dynamics included reactive services for voice and workflow automation, as well as enterprise applications using Spring, Quarkus, GraphQL, and BigQuery. I also delivered Java backend features for freelance clients and hold the Google Cloud Certified - Professional Cloud Architect certification.
