I’m a Backend Software Engineer with hands-on production experience in Java Spring Boot, building schema-driven microservices, REST APIs, and multi-tenant backend systems. I focus on reliability, correctness, and security—especially with ACID-compliant transaction design and JWT-based authentication.

At MAQ Software, I developed an automated system to generate Apache Avro schemas from Java JPA entities using annotations, and built a custom Gradle plugin to support schema generation with generic types, field shadowing, and multi-module projects. I also implemented a Spring Boot REST service for schema registration, versioning, and retrieval via Apicurio Registry, extracting field-level relationship metadata from JPA mappings.

In my projects, I built a FinTech wallet service with double-entry ledger architecture and immutable transaction records, resolving double-spending under concurrency using JPA Optimistic Locking. I design idempotent APIs with X-Idempotency-Key and create scalable search and reservation-conflict handling using date-overlap validation, indexing, caching, and rate-limiting.
