What I Build For Product Teams
Ship modern web apps — fast UI, reliable APIs, deploy-ready.
Next.js / React interfaces with intentional motion and accessibility.
Auth, data models, and admin flows that hold up in production.
Performance-minded frontends that stay maintainable as features grow.

Without Full-stack
Pretty screens that break when real data and auth arrive
Separate web / mobile / backend owners who never align
AI demos bolted on without product UX or failure paths
Rewrites every time scope moves from MVP to production
With ShiftBOi
UI, API, and data designed as one system from day one
A single full-stack partner across web and mobile surfaces
AI features that ship inside the product loop — with clear handoff
Architecture that grows from prototype to production without a reset
Selected Projects
Vibesaur Extension
Raise a dinosaur from commit quality — not just how often you push. A local-only Cursor / VS Code pet with a living island, stats desk, and star store.
SKNAT
Thai real-estate platform: smart search, maps, and compare for buyers — plus seller & admin tools for listings, leads, and sales in one stack.
Tastesiam
Discover Thai food heritage, communities, and local businesses on the map — with multilingual UX, bookings/commerce, and multi-role operator dashboards.
Seenpi
Turn CCTV into a curated video wall — contributors publish feeds, staff compose layouts, Android TVs show multi-cam walls with weather, social, and ads.
Ship
Artillery-FDC

How the work actually runs
After the selected work, this is the honest close — how the practice runs, what fits, and what is in motion right now. Contact lives in the footer and chat; this page stays about the work.
How I work
Own the loop
UI, API, data, and deploy stay one story — so demos survive real auth, real content, and real edge cases.
Clarity under complexity
Maps, CMS, roles, and AI features only earn a place when the product stays readable for the next person who opens it.
Ship in phases
Prototype → MVP → production without a rewrite tax. Each phase should feel intentional, not disposable.
Good fit
Product builds
New web or mobile products from brief to first production deploy — including the operator tools that keep them alive.
Platform & CMS
Marketing sites, dashboards, and content pipelines where the public surface and the edit loop share one system.
AI inside the product
Assistants, workflows, and LLM features that live in the UX — with clear failure paths, not bolted-on demos.
Not a fit
- Design-only passes with no engineering ownership
- Spec dumps without a product owner in the loop
- AI demos that never touch real product UX
- Rewrites sold as “just a redesign”
In motion
Live notes so the portfolio doesn't pretend everything is finished.
- Building
Selected work that stays editable
Freight brands, owner CMS loops, and product surfaces where the public page and the edit path share one system.
- Shipping
Tools people keep open
Editor pets, map-first ops UIs, and video walls — demos that survive real data instead of dying at the screenshot.
- Exploring
AI inside the product loop
Assistants and workflows that live in the UX with clear failure paths — not a chatbot sticker on a marketing page.
