Hi, I'm Gausul Wara —Backend-Focused Software Developer

I build performance-driven backend systems with strong foundations in system design and distributed system basics. Experienced in developing RESTful APIs, real-time analytics services, and production-ready applications using clean architecture principles.

Recently built a high-performance analytics engine processing 100K+ events/day with database-level aggregation and optimized query indexing. Passionate about writing maintainable, scalable code that performs reliably under load.
