About Me

Iā€™m a backend engineer passionate about building scalable, high-performance systems that combine clean architecture with cloud-native technologies. My favorite work lies at the intersection of performance, reliability, and simplicity ā€” creating backend solutions that are not only powerful but also thoughtfully engineered.

Currently, I'm a Senior Software Engineer specializing in Java, Kubernetes, and enterprise integration systems. I focus on developing microservices and backend infrastructures that deliver seamless performance under high load, ensuring reliability, scalability, and maintainability.

In the past, I've had the opportunity to work across a wide range of environments ā€” from high-load banking systems to startup projects and cloud-native solutions. I've also built internal tools for code quality automation, improving engineering workflows and enhancing development efficiency.

In my spare time, I enjoy learning new technologies, refining my personal projects, and sharpening my engineering skills. Outside of coding, Iā€™m passionate about playing golf in the summer, hitting the slopes for skiing in the winter, and starting my mornings with a strong espresso. I'm always energized by the challenge of building faster, more reliable, and elegantly designed systems.

Projects

Logix ā€” High-Performance Log Ingestion & Validation Platform

A real-time log collection, strict JSON Schema validation, and routing platform. Prevents invalid, unstructured data from reaching search indexes by enforcing schema contracts at the entry point. Handles 20K+ events/sec with guaranteed delivery (WAL + retry/DLQ). Single-tenant architecture with full fault isolation.

Key contributions: Designed three-service architecture, built ingestor (HTTP ingestion, JSON Schema validation, WAL fallback) and sink (continuous consumer, batch indexing, retry/DLQ pipeline), unified config system, Docker Compose sandbox, Helm chart, CI/CD pipeline, load testing (2.6M events, zero data loss), 48 unit tests, full documentation.
