Professional Journey

Java Backend Engineer

Recruitment Platform API • Notification Platform
  • Designed and delivered Recruitment Platform API on Java 21 + Spring Boot, covering JWT authentication, role-based access control, recruiter-owned companies, vacancy publishing, candidate applications, and recruiter review workflows.
  • Built Notification Platform as a separate backend system for template management, notification creation, dispatch and cancel flows, delivery-attempt history, and ownership-aware operator, manager, and admin access rules.
  • Structured both services around clear REST boundaries, validation rules, and predictable business logic so the APIs stayed understandable as the workflows became more detailed.
  • Implemented PostgreSQL persistence with Flyway migrations, Swagger-documented endpoints, and backend modules that are easy to run, inspect, and continue extending.
  • Used Spring Security and JWT flows to keep protected actions explicit, secure, and aligned with real product rules instead of scattered access checks.
  • Worked with Docker, Compose, and backend testing tools to keep the services closer to production-style engineering rather than toy demo APIs.

Kotlin Multiplatform Developer

Cross-Platform Product Work
  • Built Android product flows with close attention to state handling, lifecycle behavior, and implementation quality, then carried the same rigor into shared Kotlin code.
  • Used Kotlin Multiplatform to move business logic out of duplicated client implementations and into cleaner reusable modules with clearer ownership.
  • Worked on architecture decisions that improved consistency between mobile surfaces and reduced maintenance overhead across shared product behavior.
  • Strengthened my understanding of domain boundaries, shared logic design, and how implementation decisions affect maintainability across platforms.
  • That foundation shaped how I now approach backend systems: clear contracts, predictable state, and business logic that remains understandable over time.
