I own the path from idea to production.

I turn ambiguous product ideas into production-ready digital products through product judgment, full-stack engineering, and AI-native execution.

  • Laravel
  • Supabase
  • Cloudflare
  • MySQL
  • AI Agents

The difference

Most portfolios show what someone can design or code.

Mine shows how I turn ambiguity into a system that ships.

01 / Selected products

Built around real product behavior.

I care about the logic underneath: discovery, operations, data, admin, mobile behavior, deployment, and what happens when users do something unexpected.

02 / Build Lab 2.0

Give me a problem. Watch the system take shape.

A deterministic, interactive demonstration of how I move from a brief to product architecture, risks, tests, and deployment—without pretending there is an AI API behind it.

Choose a product brief

My default question“What has to be true for this product to keep working after launch?”
PRODUCT SYSTEM / MARKETPLACE Thinking in public
The brief

Start with owned brands, then onboard external shops without rebuilding the product.

Problem

Ownership, inventory, checkout, and operations become tangled as more sellers enter the system.

Assumption

A shared catalogue model can support both owned and partner inventory if ownership rules are explicit from day one.

Decision

Model shops, variants, stock, and order states before investing in storefront polish.

  1. 01Problem

    Multi-shop growth without operational drift

  2. 02User experience

    Shop discovery, filters, variants, checkout

  3. 03Frontend

    Next.js storefront and account flows

  4. 04Backend

    Laravel APIs and Filament operations

  5. 05Data

    MySQL: shops, SKUs, stock, orders

  6. 06AI / automation

    Spec agents, fixtures, regression scenarios

  7. 07QA

    Stock conflicts, roles, failed checkout

  8. 08Deployment

    Cloudflare edge, observe, iterate

Risks I’d surface
  • Seller ownership leaks
  • Variant stock conflicts
  • Order-state ambiguity
Unhappy paths
  • Payment succeeds but stock update fails
  • A seller edits another shop’s product
  • A split order is partially returned
What I’d test first

Run one order with two shops, two variants, and a partial failure through the full operations path.

03 / How I work

AI is leverage. Ownership is the skill.

I use AI across research, architecture, implementation, visual production, debugging, and QA. I remain responsible for the problem, the edge cases, and what reaches production.

  1. 01

    Frame

    Users, constraints, priorities, and the decision the product must make easier.

  2. 02

    Shape

    Flows, information architecture, responsive behavior, and system boundaries.

  3. 03

    Build

    Frontend, backend, data, and integrations—with agents used deliberately.

  4. 04

    Break

    Unhappy paths, accessibility, state transitions, performance, and regression QA.

  5. 05

    Ship

    Deployment, production checks, observation, and the next useful iteration.

04 / Working stack

Full-stack enough to own the journey.

I choose tools in context. The goal is not to force every product into one stack; it is to make sound decisions and carry them through.

01

Frontend

I shape responsive product surfaces, interaction states, and component systems.

  • HTML
  • CSS
  • JavaScript
  • React
  • Next.js
  • Responsive UI
02

Backend & data

I model the rules, identities, records, and workflows beneath the interface.

  • Laravel
  • Filament
  • Supabase
  • MySQL
  • Cloudflare D1
  • APIs
  • Authentication
03

Infrastructure

I take responsibility for the route from local build to a production environment.

  • Cloudflare Workers
  • Cloudflare Pages
  • Vercel
  • DNS & domains
  • Deployment
  • Production QA
04

AI-native workflow

Agents accelerate research, implementation, debugging, and verification. Judgment stays human.

  • Codex
  • ChatGPT
  • Claude
  • Agent orchestration
  • Image generation
  • AI-assisted QA
05 / Visual range

Make it work. Then make it feel finished.

Brand and visual judgment support the product work. They do not replace it.

06 / The journey

I learned products from the physical world before I engineered them in the digital one.

I started around physical products: Textile Engineering, manufacturing, and international B2B commercial operations. Entrepreneurship then exposed me to customers, inventory, conversion, and the business systems behind every useful digital product.

2016—2021

Textile Engineering

Systems thinking, constraints, manufacturing, and production discipline.

Dec 2021—Jul 2024

Experience Group

Junior Executive (Dec 2021–May 2022) → Executive (Jun 2022–Oct 2023) → Senior Executive (Nov 2023–Jul 2024). Promoted twice while coordinating LC Waikiki and New Look accounts, commercial execution, manufacturing timelines, and delivery.

Aug 2024—Present

Entrepreneurship & owned products

Solving my own commerce problems led from storefronts into backend systems, databases, marketplaces, and increasingly complete digital products.

Now

AI Product Engineering

Product judgment, full-stack execution, and AI leverage. As Founder & Product Engineer, I started WARPIX Studio in November 2025 as an independent umbrella for owned products, prototypes, and experiments.

What I’m targeting

Small teams. Hard problems. Real ownership.

Remote-first product teams where business context, AI fluency, and the ability to cross traditional job boundaries are useful.

Got a product problem that needs an owner?

If you’re hiring for a remote product or AI role—or building something where a cross-functional builder would be useful—I’d like to hear about it.
