Flutter cross-platform delivery
Product interfaces, interaction implementation, state management and release preparation across iOS and Android.
Build Ledger
I turn unclear requirements into products that can ship and keep evolving.
I’m 王雄皓 (Hoa), a product-minded developer. I use Flutter for cross-platform experiences, then add the Node.js and WeChat layers a working product actually needs.
What I build
Taking a small-to-medium product from concept to a shippable version
Node.js backend completion
The minimum viable APIs, admin tools and delivery path so a product doesn't stop at a frontend prototype.
From requirements to release
I work best when scope definition, technical decisions and delivery milestones stay on a single, clear track.
Tools and independent product work
I keep building small, real tools — using actual usage scenarios rather than concept packaging to validate direction.

The project below represents work I'm still operating and iterating on. The remaining projects have been archived and are kept as historical build records for judgment and review — they do not represent active operations.

The Official Account turns confusing situations into actionable steps; the Mini Program then helps users organize material, check privacy and preserve an evidence timeline.

What I'm better suited for
Projects where my approach fits best
Zero-to-one lightweight products
When you need a verifiable, shippable first version fast — without overbuilding infrastructure first.
Tightening and refactoring existing products
When pages multiply, direction blurs and technical debt piles up — I help restructure before deciding what to build next.
Where technical and product judgment meet
When you need more than code — someone who can discuss boundaries, pace and delivery trade-offs alongside implementation.
