brief> "custom web app, startup-decacorn quality, built with ai"

Decacorn-qualitywebapps,builtbytwo.

Two people, both veterans of decacorn tech startups — GoPay and the wider Gojek ecosystem — now building custom webapps with AI in the loop. Designed by hand, drafted by a model, owned by you.

Start a brief See how we work

What we build

Four kinds of software. Nothing off the shelf.

Internal tools

Admin panels, dashboards and workflow screens that replace the spreadsheet your company runs on.

Client portals

The part of your product customers log into: accounts, documents, billing, support.

AI-native products

Applications where the model is the feature — drafting, classifying, answering, grounded in your own data.

Rescues and rebuilds

Stalled codebases taken over, or prototypes rebuilt properly before they outgrow you.

Selected work

Shipped, running, named with permission.

Soulbox

Booking and reservation system with integrated payment gateway — from search to paid confirmation.

Wallex

A custom AI agent for compliance workflows: transaction pre-screening before it reaches an analyst.

JHS

Custom backoffice webapp for a construction company — projects, documents and site operations in one place.

PLN Pusertif

Visitor registration management webapp integrated with existing biometric door hardware.

How we work

The same four steps on every project.

Brief

One call, one page. We write down what the software must do — and what it must not.

Drawing

We sketch the interface and the data model first. You approve a drawing, not a slide deck.

Build

A model drafts the routine code. We review every line and build the hard parts ourselves.

Run

We deploy, watch production, and hand over a codebase your next developer can read.

The model drafts. We take responsibility for every line that ships.

Founders

Two people. You work with both of us.

Ais

Engineering & growth

Ais owns architecture and the hard parts. Fifteen years of fintech and platforms: four at GoPay ending as engineering manager, Head of Technology at Amartha, and AI engineering at Wallex. Production-grade is the only grade.

Treats the model like a junior engineer with perfect recall and no taste — useful for a first draft, never for the last mile. Every line gets reviewed before it ships.

Yoga

Product & UX

Yoga owns the drawing: the brief, the interface, the data behind both. Product lead at GoToko; product manager at GoPay across Singapore, Vietnam and Thailand — KYC flows, wallet rails, merchant onboarding at scale.

Started as a developer, moved through QA into product, so every drawing knows what the build can afford. If a screen needs training to understand, it goes back to the drawing board.

Still hands-on with AI: recent hackathon prototypes went from idea to working demo in hours.

Latest activity

Mostly hackathons lately.
