What I'm looking for

I seek backend/cloud-focused roles where I can design scalable, observable systems, optimize performance, and integrate ML features within agile, collaborative teams.

I'm an experienced Senior Software Engineer with 8+ years of experience, specializing in Golang and Python, with deep expertise in event-driven systems, distributed architectures, and real-time data processing at scale with production-grade infrastructure.

I design and operate high-throughput systems using Kafka, gRPC/REST/GraphQL, and AWS infrastructure. My background includes years of production experience with Java, which gave me a solid foundation in design patterns, clean architecture, and building reliable services. I also work hands-on with React.js, bridging backend and frontend to deliver complete features and collaborate effectively across teams.

In distributed systems, I focus on Kubernetes, CI/CD, observability, and data-intensive workloads across PostgreSQL, MongoDB, and other SQL/NoSQL databases. In the AI/LLM space, I build end-to-end systems, from data pipelines and context management to multi-model orchestration, evaluation (Langfuse), and real-time streaming, always with scalability, cost, and reliability in mind.

I value simplicity, ownership, and solving real problems at scale.
