What I'm looking for

I want to build production web, mobile, and AI systems in a remote-first environment with flexible hours. I enjoy collaborating across time zones and delivering end-to-end features with strong reliability, testing, and observability.

I’m a full-stack software engineer with 3 years of professional experience building production web, mobile, and AI systems across telehealth and consumer platforms. I work remote-first with flexible hours, and I’m comfortable collaborating across time zones.

I’m strong across React Native, React, and Node.js/Bun, and I enjoy shipping end-to-end features that connect user-facing apps to reliable backends. In my current role, I built a Bun + Hono multi-agent conversational AI service on AWS Lambda with streaming responses and Pinecone vector retrieval, using OpenAI/Anthropic/Gemini APIs.

I also focus on performance and data reliability—designing database schemas and optimizing queries, with testing and observability in agile sprints. Previously, I implemented APIs, data models, and integrations with Node.js/NestJS/Flutter, deployed on AWS/DigitalOcean via Docker and GitLab CI/CD, and improved an AI art recommendation engine using vector embeddings.
