I've spent 18+ years working with US-based companies, designing, building, and improving backend systems and production infrastructure.
My focus is solving complex technical problems: understanding what's happening, identifying root causes, and turning business requirements into reliable, scalable systems.
Backend APIs and services, Kafka, asynchronous processing, queues, workers, event-driven architectures, and distributed systems.
AWS architecture and production infrastructure, including experience with Aurora, DynamoDB, SQS, SNS, S3, and CloudFront.
Performance analysis, incident investigation, root cause analysis, monitoring, and observability with Datadog, Grafana, and CloudWatch.
Requirements discovery, technical trade-offs, system design, CI/CD, integrations, and end-to-end engineering from initial concept to working systems.
