About

Professional summary

I am an AI-native software engineer with 15 years of experience building and shipping web and mobile products.

Since 2024, I have been focused on production AI work, including conversational interfaces, RAG pipelines, and streaming LLM features. I enjoy taking ambiguous problems from idea to shipped product and measuring the impact of what I build.

I work primarily with React, TypeScript, and Node.js, and I use AI tooling daily to accelerate development and delivery. I have experience designing end-to-end systems that combine product thinking, engineering execution, and practical AI integration.

My background includes marketplace flows, payments, subscriptions, authentication, shared component libraries, and observability with tools like Datadog and Sentry. I have also built AI-powered applications used in public safety and other production environments.

I have led and contributed to frontend, mobile, and full-stack initiatives across consumer, enterprise, and internal products. My experience includes native iOS, Flutter, hybrid mobile apps, REST APIs, GraphQL, and monorepo-based development.

I value ownership, clear communication, and shipping reliable software. I am comfortable working remotely, collaborating asynchronously, and mentoring through code review and technical guidance.
