What I'm looking for

I’m looking for a senior backend role where I can build cloud-native distributed systems and high-throughput data pipelines, with strong reliability/observability. I want to mentor others and apply AI/ML integration to drive data-driven products.

I’m a Senior Software Engineer with 8+ years of experience designing and building scalable backend systems, distributed microservices, and data-intensive platforms. I focus on performance, reliability, and systems scalability—especially in high-throughput environments.

In my recent roles, I’ve engineered distributed data ingestion and asynchronous processing pipelines in Golang, using event-driven architecture with Kafka and Go workers to improve throughput and reduce latency. I design microservices that support real-time data transformation and routing across multiple services, backed by automated testing and observability.

I also bring strong data engineering and analytics expertise: building ETL/ELT workflows, stream and batch processing pipelines, and analytical data models in ClickHouse and PostgreSQL. I’m experienced integrating caching and buffering with Redis to improve system responsiveness and end-to-end processing behavior.

To keep systems future-ready, I integrate AI/ML services using Python (FastAPI, PyTorch) for capabilities like data classification and enrichment. I’m equally committed to clean architecture and mentoring, helping engineers adopt modern backend practices, concurrency patterns, and maintainable service design.
