Outsourced Development Team
Full-stack development that ships as fast as your roadmap demands.
Our frontend, backend, and QA engineers build production-ready features, integrate your stack, and ship on schedule, backed by Doublle’s AI OS for faster iteration without cutting corners on code quality.
From first sprint to final deployment, on one flat monthly plan.
Trusted by product and engineering teams worldwide.
From fast-growing startups to enterprise leaders, teams choose Doublle for full-stack development they can ship with confidence.
Why development matters
Slow builds don't just miss deadlines, they cost you
A delayed release or a buggy handoff isn't a small thing, it's the reason your competitors launch first, your customers churn before renewal, and your roadmap slips quarter after quarter. Every sprint lost to hiring, onboarding, or context-switching is a sprint your product doesn't move forward.
Most in-house teams are stretched thin, and development capacity is often the first constraint when scope grows faster than headcount. That's where a dedicated outsourced development team keeps your product shipping without pulling your core engineers off the roadmap.

Is this for you
Built for product teams who need shipped code, not another hire
Early-Stage Startups
Founders racing to ship an MVP before the next funding conversation, without runway for a full-time engineering hire.
Enterprise Teams
Enterprise teams that need extra engineering bandwidth during a platform migration, integration, or major release.
Stack Gaps
Teams missing in-house expertise in a specific language, framework, or legacy system that's blocking a project.
Overloaded Teams
In-house developers stretched across too many sprints, with technical debt piling up as a result.
For every digital touchpoint
Your next build, shipped faster, and for less than you're paying now.
We built Doublle around one idea: pair real engineers with a proprietary AI OS, and the result isn't just faster output, it's fewer bugs, cleaner architecture, and code that holds up for the people who matter most, your users and your business.
Book a demoeCommerce
Storefronts engineered for peak traffic, secure checkout, and inventory that syncs in real time. Our backend handles the transactions and scale, our frontend handles the experience, not just a design that looks good on launch day.
Mobile apps
Native iOS and Android builds that ship on schedule and pass app store review the first time. Every release goes through full QA before it reaches your users, so nothing scales into a rewrite six months in.
Web apps
Full-stack applications with clean, documented architecture your in-house team can actually extend. Frontend and backend built together from day one, not stitched together after the fact.
Websites
Fast, reliable builds with clean code underneath and QA baked into every release. Delivered without the agency overhead or the multi-week production queue.
Built for excellence
A development partner built for results - faster ship speed, fewer defects
Real numbers from real development engagements, not projections.

What's included
Everything your product needs to actually ship
From the first sprint to a fully deployed release, everything your product needs to work right and stay stable.
End-to-end Web & Mobile Development
From architecture to deployed product, we build complete web and mobile solutions focused on performance, scalability, and long-term maintainability.
Bug Fixes and Performance Optimization
Improving speed, stability, and reliability through targeted fixes or broader refactors.
Technical Consulting
Senior engineers provide strategic input across the build lifecycle to surface risks and challenge assumptions before they become costly.
Codebase Architecture and System Design
Build or restructure the technical foundation that drives consistency and scalability as your product grows.
Code and Architecture Audit
Assess your current codebase to identify technical debt, security gaps, and a clear foundation for smarter engineering decisions.
MVP Development and Prototyping
We support fast-moving teams with MVP build cycles to enable faster validation, stakeholder buy-in, and time to launch.
Prototyping and Technical Validation
Working prototypes and fast iteration cycles to test feasibility before full development, reducing risk and wasted engineering hours.
Our difference
Why product teams chooseDoublle for Development
Architecture-first builds
We start with how your system needs to scale, not just what the feature needs to do today, so every build holds up under real load and real users.
Sprint-based delivery
Structured sprints and reusable code components keep your project on a predictable timeline while adapting to changing scope.
A dedicated engineering team
Choose to work directly with the same developers throughout your engagement, so technical context never gets lost between sprints.
Deploy-ready handoff
Every release ships with documentation, tests, and clean commits, so your in-house team can maintain and extend it without guesswork.
Flexible project scope
From a singlefeature to a full rebuild
A bug fix and a full platform migration are different projects, and we scope them differently.
Whether you need a focused feature build or a ground-up rebuild, we scope our plan and approach around what you actually need, not a fixed package.
OUR PROCESS
From brief todeployed product
No black box. You'll know exactly who's working on your project and what happens at every stage.
[1]
Discovery and technical audit
We review your codebase, architecture, and requirements, identifying constraints before any planning starts.
[2]
Team assignment
You're matched with a specialized frontend, backend, or full-stack engineer, based on your stack and project complexity.
[3]
Technical consulting
Our engineers review your requirements and advise on the right approach, so the build sticks to your goals, not the easiest shortcut.
[4]
Sprint planning and scoping
We map features and dependencies before any code starts, so the build follows a plan, not guesswork.
[5]
Development and testing
Features get built in structured sprints with continuous testing, so you can review working functionality before final delivery.
[6]
Handoff and deployment
You get organized documentation, clean commits, and tests, so your engineering team can maintain and extend it without back-and-forth.
[7]
Post-launch monitoring
Track how the build performs in production and refine for speed, stability, and scale as real usage grows.

Frequently asked questions
Frontend, backend, full-stack, and mobile app development, along with QA and testing, based on your project scope and defined sprints.
Both. We can integrate with and extend an existing codebase, or build a new product from scratch, depending on what you need.
We work across the modern web stack and match the tooling to your project rather than forcing every build into one framework. - Frontend: React, Next.js, TypeScript, and Tailwind CSS for fast, production-grade interfaces. - Backend & data: Node.js, and databases like PostgreSQL / Supabase for secure, scalable APIs. - Websites & CMS: Webflow, Shopify, WordPress, and Framer when you need a marketing site that's easy to update. - Integrations: payments, auth, email, analytics, and the third-party tools your product depends on. If you already have a stack, our experts plug into it. If you're starting fresh, we recommend the setup that best fits your goals, timeline, and budget — and build it launch-ready.
Every release goes through structured testing before delivery, so features are validated before they reach your users, not after.
You get organized documentation, clean commits, and code your in-house team can maintain and extend without guesswork.
Yes. We can slot into your existing sprints and workflows, or run independently and hand off at agreed checkpoints, whichever fits your team.
You're never on your own — while you're subscribed, we'll fix anything that's not quite right. Just flag it, we jump on it straight away.
