What I'm looking for

I seek a role building scalable backend and AI-integrated systems on a collaborative team, with opportunities to lead architecture, improve reliability, and work with modern microservices and MLOps tooling.

I am an experienced backend engineer with 8+ years building scalable, high-performance systems and AI-integrated platforms. I specialize in Node.js and NestJS, and I design robust data pipelines, real-time ingestion, and service architectures for analytics and advertising products.

I've led migrations between time-series databases (VictoriaMetrics to QuestDB), implemented Kafka and RabbitMQ-based messaging with dead-letter handling, and optimized CPU-intensive tasks with worker threads. I contributed to AI-related services using Go microservices and integrations with Vertex AI and RAG-based systems.

I deploy and operate services with Docker, Kubernetes, and GitLab CI/CD, and I prioritize maintainability and type safety through rewrites to NestJS and TypeScript. I'm motivated to join innovative teams that build scalable systems and AI-driven solutions.
