I’m a Software Developer with production experience in SaaS development, focused on writing clean, scalable code that solves real-world problems. I contributed to MioSalon’s multi-tenant platform, building REST APIs and backend features that serve real users.

In my recent work, I debugged and resolved live production bugs by analyzing server logs and tracing root causes across backend and database layers. I also enhanced modules by adding validations, fixing edge-case failures, improving business logic in Java and PHP, and correcting data integrity issues in MySQL.

Currently, I’m building a production-grade Distributed API Rate Limiting system using Java 17, Spring Boot, and Redis. I designed a sliding window approach with atomic Lua scripts in Redis, enforced limits with both a Spring Filter and a custom @RateLimit AOP annotation, and exposed an Admin REST API for live request counts and reset controls.
