Founder & Developer — subscription website platform for Oregon trade businesses (free build, $297/mo, no contract)

Integrated Stripe subscription billing and built automated GitHub Actions pipelines to manage pricing, discount codes, and API credentials safely — least-privilege keys, every change verified against the live account before it takes effect.
Architected the backend on serverless cloud functions and cloud data storage; built and maintain 25+ automated deployment and quality-control pipelines covering testing, data validation, commercially-licensed photo/video sourcing and compliance, and live-site verification.
Built a companion sales toolkit (mobile-first cold-call console, offline-capable notes sync, traffic-analytics dashboard), plus PROSPECT (lead-generation: business search, website audits, owner lookups) and WATCHTOWER (keyword monitoring across classifieds, forums and RSS with digest alerts).
