Most people who hire a developer have no idea what's happening until something is "finished". With Dublingoo you see the design before we build it, try every new feature before your customers do, and pay only after you approve each stage. When we're done, everything we made belongs to you.
We ask questions until we understand your business, then write down exactly what will be built.
You click through a realistic mock-up of the app and change anything you don't like, for free.
Every two weeks we show you working features on a private preview site you can try yourself.
We go live, then hand you every file, password and guide, with 30 days of free bug fixes.
If you've worked with an agency before, some of the left-hand column may sound familiar.
One experienced team covering design, building, hosting and support.
Customer portals, dashboards, booking systems and software you sell to other businesses, built to stay fast as you grow.
Multi-tenant architecture, role-based permissions, real-time dashboards. React / Next.js, Node.js, Python, PHP / Laravel, PostgreSQL, Redis.
One app that works on both phones, keeps working with a weak signal, sends notifications, and gets approved by the App Store and Google Play.
Flutter or React Native, offline-first sync, push notification infrastructure, store submission and compliance.
Taking payments, digital wallets, lending and account balances. Built so money is never counted twice and identity checks are handled properly.
Idempotent double-entry ledgers, Stripe / Adyen / Plaid, KYC/AML flows, PCI-DSS scope reduction.
Logo, colours and style guide if you need them, then screens that are easy to use, including for people with disabilities.
User research, Figma design system with tokens shared with the codebase, WCAG 2.1 AA.
Your domain name, email setup, secure hosting, automatic backups and alerts if anything goes down. Updates go live without the site going offline.
AWS / GCP / Azure, Terraform, Docker, GitHub Actions CI/CD, blue/green deploys, Sentry / Datadog monitoring.
Slow, buggy, or left behind by a previous developer? In two weeks we review it and give you a plain-English report on what's wrong and what to fix first.
Code quality and test coverage review, security scan, database query profiling, cloud cost review, remediation roadmap.
We've worked in finance, education, automotive and more. Industries where mistakes are expensive.
Businesses can send and receive money across borders and see every transaction in one place. New customers verify their identity online in minutes instead of days.
We rebuilt a learning system that used to crash during exam week, and gave parents an app to follow attendance, fees and results.
Mechanics get jobs on their phone, even in garages with no signal, and the office sees every job live on one screen.
"[Client quote placeholder: what changed for them, in their own words, ideally about the process and handover, not just the result.]"
"[Client quote placeholder: e.g. how easy it was for their in-house team to take over after launch.]"
Here's a typical project, a website plus a mobile app, week by week. Nothing moves to the next stage until you say so.
We keep three copies of your product. New work starts in the first, you try it in the second, and only what you've approved reaches the third, the one your customers use.
Ephemeral preview environments per pull request, staging mirrors production with sanitised data, GitHub Actions CI/CD with Dependabot / Snyk, immutable release tags, multi-AZ zero-downtime deploys.
Enough that you could hire your own team, switch developers, or show investors exactly what you've built.
A written description of everything the product does, who it's for, and what to build next.
Your logo in every format, brand guide, and the original design files for every screen.
Every line, stored in your company's GitHub account, with automatic tests that catch mistakes.
Diagrams and documents a new developer can read to understand the system quickly.
Step-by-step guides for updates, backups and what to do if something goes wrong.
Recorded tours of every part of the system, plus every password and account handed over in a log.
A sample pack from a real project, with private details removed. It shows exactly the kind of documents and updates you'd receive.
The download link appears right away. We won't add you to a mailing list.
Every project gets a written quote. These are the three ways clients usually start.
Perfect if you're raising money, need board approval, or want to brief your own developers. You get everything needed to build, with us or anyone else.
We take your idea all the way to a live product in the hands of your customers, and hand everything over to you.
We keep your product running smoothly and securely, and add new features as your business grows.
Anything else? Just ask on the call. There are no silly questions.
A free 30-minute call with someone who actually builds products, not a salesperson. We'll tell you honestly whether we're the right fit, roughly what it would cost, and what the first month would look like.
Happy to sign an NDA (a confidentiality agreement) before you share any details.
