Denver Contact Improv

Website, technical SEO and client-run editing

Michael Bernal teaches Contact Improvisation in Denver. I designed and built his site and its sister site, Art of Living CI: ten pages, a page for each class series, a beginner’s guide, and an FAQ in his own words. Both are static Next.js exports, so they load from a CDN with no server to maintain.

The search work is on every page rather than bolted on: titles and descriptions written from the phrases people type, canonical URLs, structured data for the business, the FAQ and the guide, a sitemap, and sharing cards. The sister site points its canonicals at the main domain so the two never compete. The full list is under SEO methods.

Michael updates the site himself through a private chat I built for him. He previews every change on a staging host, and nothing reaches production until he asks for it.

Rivr

A federated coordination platform, and the site that explains it

Rivr is a social coordination network: events, groups, offerings, jobs and a shared map, with governance and a treasury for the groups that need them. I lead its technology, product and infrastructure.

It is federated. A hub connects sovereign person and group instances that keep their own data, and peers trade signed events instead of trusting one central database. An assistant inside the app works through the same permissions as the person it acts for.

I built Rivr’s permission-aware assistant architecture to combine subjective knowledge graphs, episodic memory, semantic retrieval and document intelligence into a working model specific to each person’s context. Its inference path uses JEV Sys 1 for fast routing and classification, LLM-backed NLP Sys 2 for deeper reasoning, and deterministic validation before natural language becomes correctly placed Rivr tasks, decisions, knowledge and workflows.

The XR experience lets you travel from a globe into Boulder and explore nearby activity and project work as spatial cards.

The landing site at rivr.social is static HTML that I ported from Squarespace and serve from the same infrastructure. This site is published from my own Rivr instance, which is why the homepage can list live objects from it.

Social post planner

Post design, scheduling and delivery, automated

A planner for whoever runs a group’s social accounts. A post starts as a photo and a caption; the planner shows where it will sit on the profile and how the platform will frame it, because a grid that lies about framing is worse than no grid.

Once a time is set, a publishing run delivers the post to each destination and records what happened per channel. A post can land on one platform and fail on another, and the person sees which, along with whether the fix is a new token or a different post.

Each account is reached with a token its owner pastes in. Tokens are encrypted at rest, checked against the platform the moment they are saved, and never written to a log or an error message.

Credentials and account ownership

A written protocol for who holds the keys

A small site still touches a registrar, DNS, a host, a code repository and usually an AI subscription. If those sit in the developer’s accounts, the client does not own their own website. I write down who owns each one and how it reaches the client before anything is deployed.

The protocol covers where secrets live, how narrowly each credential is scoped, how DNS moves without breaking mail, what to do when something leaks, and the order of the final handoff. The order matters: new credentials are proven to work before the old ones are revoked.

The Riverside

Systems integration, admin APIs and the front ends on top

The Riverside is an events venue in Boulder. Over four years there I integrated point-of-sale, payroll, shift management, product production and venue booking into one connected operational system, replacing disconnected manual tracking.

The backbone is a set of Cloudflare Workers on one domain. Webhooks from the booking and scheduling tools land in the shared record within seconds. A public events site builds itself from that record, sells tickets through Stripe, and writes each sale and guestbook entry back against the event.

I also built much of the current public-facing websites for The Riverside and The Coffee Stand, connecting the venue, café and events experience online.

On top of the data sit the pieces people touch: the events pages, a guestbook, a shift checklist for staff, and Rivertree, an app that turned the venue’s points-for-tasks model into software.

OneBoulder

Community app and local coordination

OneBoulder brought profiles, events, local discovery and participation into one place for the Boulder community. My work on the app and its supporting systems shaped how people could find each other and organize around shared activity.
