From Vibe‑coded prototype to dependable product

How we turn a built draft into something your team and customers can trust

The Challenge

Fix‑one‑thing, break‑another: changes in one place silently break another because the code is a patchwork, not a plan.Runaway technical debt: each prompt adds one‑off code; after a few weeks, small tweaks feel risky and slow.Hidden security risks: exposed keys, weak auth, unsafe inputs, no audit trail.No scale path: good demo, but slows and crashes with more users, data, and features.Credit burn & rewrite risk: chasing bugs with prompts eats credits; keep patching and you’ll pay twice later.

Our Approach: Productise, not “just fix bugs”

A disruptive rewrite isn’t always the first move. We keep what’s proven (flows that work), then give the app a backbone—structure, data, security, and a clean way to add features—so changes stop breaking old work.

JDD Agency have a very robust system of project management and a very personable and effective approach to the development process. It is difficult to see where this may be improved.

Solution #1 — Blueprint & Architecture

Map screens, flows, and data. Extract the true business rules. Replace tangled code with small, testable parts and a single style.

Solution #2 — State & Data that don’t fight you

Centralise state, normalise data, version the schema, and add basic migrations. No more phantom resets or duplicate logic.

Solution #3 — Security & Secrets

Move secrets server‑side, validate inputs, lock down auth/roles, add rate limits and an audit trail. Basics that prevent big headaches.

Solution #4 — Integration Surface

Auth, payments, CRM/ERP, files, analytics—all behind stable interfaces so one change doesn’t ripple through the app.

Solution #5 — Observability & CI

Crash/error logging, simple dashboards, and CI checks. We add a few tests where it matters to stop regressions early.

The Outcome: Stability first, then speed

Changes stop breaking old features; regressions drop. Clear structure and data your team can extend. Fewer incidents; faster screens and flows. Security basics in place—and visible. A plan for the next 2–4 weeks that isn’t “try more prompts”.

Is your prototype holding you back?

If you’re stuck in the break‑fix loop, burning credits, or worried about security, it’s costing more than time—it’s costing momentum.

Why JDD

Let’s have a practical, 20‑minute chat about one specific flow that’s causing headaches. No jargon. No hard sell. Just a straightforward plan to make it solid.

If your factory is still losing hours to manual jobs, it isn’t failure — it’s just a sign of low digital maturity. The sooner you tackle it, the faster you win the hours back.
