• Built the developer platform for an AI presentation product: the MCP server, the public API and the generation UX.

• Architected and shipped the hosted MCP server: a production TypeScript service exposing 8 tools that let Claude and ChatGPT generate presentations, with WorkOS OAuth, JWT auth and async polling, deployed on AWS ECS via Docker and CI/CD.

• Designed and built the first public REST API with API-key and OAuth auth, presentation generation, templates and S3 presigned-URL attachments.

• Authored and published the n8n community node to npm and n8n's official directory, passing n8n's strict-mode security review.

• Drove submissions to the Anthropic MCP directory and the OpenAI ChatGPT app directory, including tool annotations, domain verification and CORS and security setup.

• Built a Next.js reference app on Vercel demonstrating real-time generation over the public API, and authored the public developer docs.

• Architected and built the complete frontend for a platform that creates and manages promotional campaigns.

• Led a codebase refactor that improved maintainability, scalability and development velocity.

• Integrated and optimized backend API connections with efficient data fetching and error handling.

• Improved UX with a consistent design system, accessibility standards and performance optimizations.

• Built voice agents that pick up the phone for restaurants and clinics.

• Fixed callers getting cut off mid-sentence by splitting turn detection into two profiles: a 0.5 threshold with 450ms trailing silence during the call, and a stricter 0.8 with 700ms during the greeting. Line noise on pickup stopped counting as speech.

• Built an ambience mixer that blends a restaurant background bed into the outbound stream at 20ms mu-law frames with crossfade, level-clamped so it never sits on top of the speech.

• Cut latency on live calls by moving to smaller speech models, then reverted when word accuracy dropped.

• Started the medical receptionist product from its first commit and built the clinic flow end to end, down to a Telnyx SIP trunk into ElevenLabs with inbound and outbound calls working.
