What I'm looking for

I seek roles where I can modernize backends, improve observability and CI/CD, and build reliable data/ML pipelines within collaborative, performance-focused teams that value automation and measurable SLO-driven outcomes.

I am a senior software engineer focused on delivery speed, reliability, and pragmatic cloud architectures that enable frequent, low-risk releases. I modernize backends and harden data pipelines, shipping production-ready Python, C#/.NET, TypeScript, and AI/ML services with strong CI/CD, testing, and end-to-end observability.

I have led efforts to reduce alert fatigue, accelerate safe deploys, and eliminate on-call churn by implementing OpenTelemetry, Prometheus, Grafana, resilient pipelines, SLOs/SLIs, and standardized runbooks. My work includes building reproducible ETL and ML pipelines, containerized ephemeral dev environments, Terraform infrastructure for multi-cloud provisioning, and observability across Kafka, Redis, and .NET APIs to reduce incidents and improve developer velocity.
