I build
the whole
thing.

The business.
The software.
The way it reaches people.

I design the business model, create the brand, build the backend, run acquisition and make the analytics work.

01 / Selected builds

Ideas with
infrastructure.

Each business has its own offer, audience and operating system. Here’s what I built around them.

Business + platform

I built the business and technical systems behind a Los Angeles rental operation, connecting fleet availability and pricing to payment, onboarding and handover.

Owned: Business and product design, renter and operator applications, backend integrations, marketing and analytics.

Inside the build

Customer experience

Vehicle selection, payment-first checkout and resumable onboarding, with pricing, promotions and referrals connected to the trip.

Operating system

Separate renter and operator applications. A Python Model Context Protocol service gives agents public fleet tools and authenticated operator actions.

Measurement & release

Booking-intent reports and backend integrations, with desktop, mobile, payment-flow and access checks before release.

02 / Membership & hospitality↗

Business + platform

I built the business model, brand and technical platform for a private members network, from referral entry to member stays, events and operator workflows.

Owned: Business model, branding and marketing strategy, backend, campaigns, cold email outreach and analytics.

Inside the build

Business & brand

I developed the business model, membership proposition and brand, and shaped the marketing angle around the audience and experience.

Platform

I built the backend and separate member and operator applications around referral applications, human screening and hospitality requests.

Acquisition & analytics

I ran campaigns, implemented cold email outreach and built the analytics layer, connecting acquisition to the membership and operating workflows.

Business + acquisition

I built the business and technical setup around private DJ lessons and music production. The work ran from the business model and brand through the website, backend and customer acquisition.

Owned: Business model, branding, marketing angle and strategy, backend, campaigns, cold email outreach and analytics.

Inside the build

Business & positioning

I designed the business model, created the branding and shaped the lesson offer and marketing angle.

Website & backend

I designed and built the website and backend, connecting the offer to the consultation and acquisition process.

Campaigns & measurement

I developed the marketing strategy, ran campaigns, implemented cold email outreach and built the analytics layer.

04 / People & agents↗

ClawPanel

Product + engineering

I design and build a workspace for people and connected agents to work with the same project context, shared files and knowledge, with permissions tied to the work.

Owned: Product and business design, application and backend engineering, agent delivery and review systems.

Inside the build

Product & backend

I define the workspace, build the application and backend, and connect people and agents to shared project material.

Access & delivery

Project permissions and authenticated connections govern access. I built the delivery system around scoped work, review and acceptance.

Explore the workspace

Public product access is by invitation. I can demonstrate the implementation and explain the technical decisions in a controlled walkthrough.

02 / How I work

The pieces
have to connect.

The offer shapes the product. The product shapes the backend. Acquisition brings people in. Analytics tells you what happens next.

01

Design the business.

Audience, offer, business model and positioning. Decide what people are buying and how the business delivers it.

02

Build the system.

Customer experience, backend, data and operations. My foundation is Python, SQL and cloud platforms, with TypeScript and React in the application layer.

03

Take it to market.

Brand, campaigns, cold email and conversion paths. Build the measurement layer alongside the acquisition work.

I use coding agents in implementation and own the architecture, technical decisions and acceptance of the work.

03 / Data foundation

Built on
enterprise experience.

Data pipelines and advertising reporting at Amagi and Crackle. Analytics, experimentation and implementation quality at Beachbody. Data-platform modernization and marketing operations at ZS for Amgen.
