Message

At FORNAX ENERGY, I own backend architecture and service delivery for a Smart Grid platform supporting 400,000+ smart meters and billions of telemetry events. I designed REST and gRPC APIs for secure device communication and built Kafka streaming pipelines for real-time telemetry.

I also engineered data models with PostgreSQL, Elasticsearch, and StarRocks, and built fault-tolerant workflows in Temporal to manage commands across field devices. My work includes multi-tenant access control using Keycloak.

At ASA CO, I led backend implementation for fintech and content-processing systems, including an LLM-powered content moderation system. Earlier at NARVAN STARTUP STUDIO, I developed backend services and messaging modules and contributed to refactoring a monolith into microservices.
