02 — APPS & PORTALS

Mobile-first portals,
native apps when justified.

Client and patient portals built mobile-first, where most people actually arrive. Native iOS and Android when the product genuinely demands it — never as a reflex.

  • Mobile-first client and patient portals
  • Intake, scheduling, and document collection on mobile
  • Native iOS — Swift and SwiftUI
  • Native Android — Kotlin and Jetpack Compose
  • Cross-platform — React Native or Flutter, when it fits
  • App Store and Play Store launch support
  • Swift
  • Kotlin
  • React Native
  • Flutter

03 — WORKFLOWS & PLATFORMS

Intake, documents, dashboards —
the workflows behind the brand.

Intake and booking flows, secure document collection, admin dashboards, and full multi-tenant SaaS foundations when the work warrants it. Planned in from day one so the operational software grows with the business, not around it.

  • Intake forms and appointment request flows
  • Secure document collection and review workflows
  • Admin dashboards and internal workflow software
  • Auth, billing, and role-based access — Clerk, Auth0, Supabase, Stripe
  • Postgres and multi-tenant data modeling
  • Security-minded architecture with audit-aware foundations
  • Postgres
  • Stripe
  • Clerk
  • Vercel
  • AWS
  • Node

04 — AI AUTOMATION & FOLLOW-UPS

AI workflows that
actually save time.

AI flows that fit how your team actually works — retrieval over your documents, agents that do real work, and reminders and follow-ups that replace the spreadsheet someone is still updating every Monday morning.

  • Reminders, follow-ups, and re-engagement systems
  • Retrieval — pgvector, Pinecone, or Weaviate
  • Agents — Claude, GPT, and tool-use workflows
  • Automations — n8n, Make, and custom orchestration
  • Internal dashboards with AI summaries
  • Human-in-the-loop guardrails by default
  • Claude
  • OpenAI
  • LangChain
  • n8n
  • Make

Integrates with

  • Notion
  • Slack
  • HubSpot
  • Salesforce
  • Zapier
  • Make
  • n8n

ENGAGEMENTS

Choose the shape of the build.

Engagements are scoped around the system you need — launch site, mobile portal, or workflow platform. Pricing is shared after a short strategy call, once we understand what you are actually building.

  • SPRINT

    Focused build sprint

    Best for a launch site, a portal slice, or a high-leverage workflow improvement.

    A focused engagement for teams that need a sharp plan, a clean launch, or a specific system shipped without dragging scope for months.

    • Discovery and technical direction
    • One focused website, portal, or workflow slice
    • Design and engineering execution
    • Launch support and handoff notes
    Plan a sprint →
  • BUILD

    Full front-office build

    Best for the full build — website, portal or app, intake, documents, and dashboards.

    A complete build partnership for service businesses that need product thinking, engineering depth, and launch discipline in one place.

    • Product strategy and architecture
    • Premium interface design
    • Full-stack implementation across web, mobile, and workflows
    • QA, accessibility, and production launch support
    • Post-launch iteration plan
    Scope the build →
  • CUSTOM

    Custom partnership

    Best for multi-location brands, complex systems, and long-term product support.

    For teams with unusual constraints, legacy systems, multiple stakeholders, or a roadmap that needs disciplined execution over time.

    • Custom roadmap and phased delivery
    • Architecture review and risk planning
    • Integrations, automation, and internal tooling
    • Ongoing product and engineering support
