PETER KARL GUMAPAC

Founder-side COO / CTO · Product Lead / Product Engineer

Hire me when product, operations, and execution need one owner.

I help founder-led teams turn messy ideas into usable workflows, clean systems, QA discipline, and shipped product without losing operating cadence.

How I support founders

Product, operations, and technology moving under one owner.

For founder-led teams, I sit between strategy and implementation: product judgment, systems design, AI workflows, QA discipline, and operating cadence in one accountable lane.

Founder Operating System Translate founder priorities into workflows, ownership maps, reporting, and the weekly cadence that keeps teams moving. COO layer
Product Strategy & Specs Shape product direction, MVP scope, user flows, PRDs, acceptance criteria, and the handoff from idea to implementation. Product lead
App & Workflow Build Build or guide React, Next.js, automation, integrations, internal tools, dashboards, and AI-assisted operating workflows. CTO layer
QA, UI/UX & Launch Review flows, test implementation, identify friction, tighten edge cases, and keep product quality tied to real users. Ship quality
AI & Automation Ops Use Claude, Codex, ChatGPT, MCP-style workflows, routing logic, and automations only where they remove actual drag. Leverage

AfterStay

Building hospitality product surfaces from operator pain: AfterStay.org, travel.afterstay.org, guest-facing workflows, product positioning, and the system layer behind a stronger post-stay experience.

What I built

  • AfterStay / NestOps as a white-label STR operating layer around task coordination, guest experience, owner workflows, team visibility, and post-stay surfaces.
  • Product strategy, PRD v1.1, Figma brief, competitor comparison, task workspace spec, WebGL landing prototype, dashboard prototype, and travel.afterstay.org.

Hiring signal

  • Shows founder/product judgment grounded in real hospitality operations, not a generic SaaS dashboard idea.
  • Useful when you need someone who can move from positioning to specs to prototype to QA without waiting on a separate team for every step.
COO / CTO · 2023 — Present

Dinbnb / Lev Collection

COO / CTO for a Norway-based STR business, responsible for the operating backbone behind roughly 120 Bergen and Oslo units: PMS/RMS decisions, API workflows, SOPs, owner reporting, revenue visibility, platform cleanup, and team execution.

COO / CTO mandate

  • Translate founder direction into the operating system: priorities, owner map, weekly cadence, SOPs, dashboards, revenue reviews, guest standards, and accountability loops.
  • Own cross-functional execution across guest operations, listings, revenue, maintenance, owner communication, remote teams, and platform decisions across Bergen and Oslo.

Operating stack ownership

  • Shape the stack end to end: Guesty/Mews evaluation, PMS/RMS and OTA workflows, API/data flows, automations, reporting logic, onboarding, escalation paths, QA checks, and team handoffs.
  • Built owner-reporting and quality systems including the LEV Collection Owner Statement Reader, owner communication SOP, listing description system, and performance reports that exposed market-level quality gaps.
Native product · ongoing

ODIN / ODIN Notch

Building and iterating on AI-native productivity surfaces: native app interaction, product feel, QA loops, visual polish, workflow design, and a tool layer that behaves like a real product instead of a demo.

What I build

  • AI-native and native productivity surfaces around fast capture, context-aware actions, quick access, and practical workflow automation.
  • Product feel, visual polish, QA loops, desktop interaction patterns, and implementation details that make the tool feel usable.

Hiring signal

  • Useful for founder-led teams that need someone who can review product UX, debug implementation quality, and still ship hands-on.
  • Combines product judgment with build execution across web, AI, and native-style workflows.
AI workflow systems · ongoing

Systems, Agents & QA

Designing practical AI-assisted workflows with Claude, Codex, ChatGPT, MCP-style integrations, UI/UX review agents, QA agents, routing logic, and automation that supports execution instead of replacing judgment.

AgentsUI/UX review and QA checks
WorkflowsSpecs, routing, SOPs
StackAI, product, operations
ClaudeCodexChatGPTMCP WorkflowsAutomation

What I design

  • Conditional routing, AI-assisted QA, UI/UX review agents, browser QA, operating briefs, SOP logic, and workflow automation.
  • Claude, Codex, ChatGPT, OpenAI, MCP-style flows, Airtable, Zapier, Make, Slack, GitHub, and local app workflows.

Hiring signal

  • AI is the leverage layer, not the headline. I use it to reduce repetitive work, improve review quality, and tighten execution loops.
  • Best for teams that need practical systems, not a pile of disconnected prompts.

Software, AI, and operating stack

Stack I can operate across when product and operations meet.

For founder-led teams, the value is not tool familiarity alone. It is knowing which system should exist, how it should work, and how to make the team actually use it.

Founder system

Vision into execution

Translate founder ideas into positioning, PRDs, MVP scope, operating workflows, accountability rhythms, and measurable execution.

Product build

Specs to shipped UI

Product discovery, Figma briefs, user workflow mapping, React/Next builds, QA loops, and implementation handoff.

AI architecture

Agent-assisted work

Conditional routing, AI agents, QA agents, UI/UX review agents, MCP-style workflows, and automations that reduce repetitive work.

Operating stack

Data flow and visibility

Connect PMS, CRM, revenue, payments, docs, dashboards, Slack, and reporting so leadership sees what is actually happening.

Executive operator

Hands-on leadership

Strategic planning, SOPs, department leads, tech stack cleanup, automation, coaching, and direct implementation when needed.
