About

Backend engineer with 3+ years building distributed systems across Java and Kotlin. Full backend stack — REST APIs, async messaging with Kafka and AWS SQS/SNS, reactive services with WebFlux, cloud deployments, and containerised workloads. Spring Boot for rich ecosystems, Quarkus/Ktor for lightweight services — right tool for the job. Currently exploring AI engineering: local LLMs, RAG pipelines, and agent patterns.
