What I'm looking for

I seek senior engineering roles building scalable, API-first and AI-enabled products with strong cross-functional collaboration, observability, and opportunities to improve developer productivity.

I am a senior software engineer specializing in Python full-stack development, cloud-native systems, and AI-enabled data workflows. I design and ship production-grade backend services, SDKs, and integrations that improve developer productivity and customer onboarding.

Across roles at Flatfile, Chronosphere, and Inspiring Apps, I led implementation of AI-driven features, telemetry pipelines, and secure fintech backends—driving large performance gains, cost reductions, and higher adoption. I regularly collaborate with product and UX teams to embed complex logic into user-facing experiences.

I focus on reliability, scalability, and developer ergonomics: building event-driven architectures, observability tooling, and automation that accelerate delivery and reduce operational burden. I bring a results-oriented, cross-functional approach to fast-paced engineering organizations.
