Software Development
Web Application Development for Products and Internal Systems
Web app development from one senior team. We design, build and run SaaS products, MVPs, dashboards and internal tools on a stack your own team can take over.
- A working first version in your hands early
- One team across frontend, backend and cloud
- Documented code and infrastructure you own
- A release process that keeps working after launch
Overview
A web application is software your customers or staff use in a browser to get real work done. It has accounts, permissions, data that must stay correct, payments or integrations behind it, and a release process that has to keep working after launch. The screens are the visible part. The data model, the API and the infrastructure decide whether the product holds up.

Capabilities
What we build
SaaS products
Multi-tenant products with accounts, roles, subscription billing and the admin tools needed to run them.
MVPs and first versions
A focused first release that real users can complete a job with, built on a foundation that lasts.
Dashboards and internal tools
Operational software that replaces spreadsheets and manual steps for your own team.
Customer-facing platforms
Booking, ordering, marketplace and account systems that customers use directly.
Integrations and payments
Stripe billing, CRMs, ERPs, email and messaging providers connected reliably to your application.
Modernization
Step by step replacement of an aging system, with data migrated safely and no long freeze on features.
Why Dude Lemon
Why teams choose us as their web development company
You work directly with the senior engineers building your product. They scope the work in writing, show working software early, and make the architecture decisions with you instead of around you. One team owns the frontend, backend and infrastructure, which removes the integration gaps that slow most projects down.
From MVP to a product people pay for
In web app development, a first version should prove the idea with the smallest set of features that real users can complete a job with. We help you choose that set, build it on a foundation that will not need to be thrown away, and put it in front of users quickly. Accounts, permissions and the data model are designed properly from the start, because those are the parts that are expensive to change later.
How we work
A clear path from idea to production.
Discovery and scope
We learn the business goal, the users and the constraints, then write a plan with scope, architecture and a realistic timeline.
.01Design and data model
We design the key screens and the data model together, so what you approve is what gets built.
.02Build in milestones
We ship working software in stages, starting with the highest-value flow, and you review each stage on a live environment.
.03Harden and launch
We add tests, monitoring, backups and security controls, then launch on production infrastructure.
.04Operate and grow
We support the product after launch with new features, performance work and on-call cover on a retainer.
.05React and Next.js, Node.js and TypeScript, PostgreSQL, AWS, Stripe billing, Multi-tenant architecture, Automated testing, CI/CD
Engagement and pricing
Custom pricing, based on project scope.
Every project is scoped individually. After a short discovery call you receive a clear written estimate, with no obligation. The engagement types below show how we usually structure the work.
First version
A focused release that proves the product with real users.
- Accounts and core workflow
- Production deployment
- Documented codebase
Full product
A complete application with billing, roles and integrations.
- Subscription billing
- Roles and permissions
- Third-party integrations
- Monitoring and backups
Ongoing engineering
A dedicated team that keeps building and running the product.
- Monthly feature releases
- Performance and security work
- On-call support
Web Application Development FAQ
Frequently asked questions.
Anything we have not answered here, ask us directly. A senior engineer replies.
Contact usWhat is the difference between a website and a web application?
A website mainly presents information. A web application lets signed-in users do work: manage an account, place orders, run reports or collaborate. Web applications need a data model, an API, permissions and a release process, which is why they are engineered differently from a marketing site.
Which technologies do you build web applications with?
Our default stack is React and Next.js on the frontend, Node.js and TypeScript on the backend, PostgreSQL for data, and AWS for hosting. It is widely used, well documented and easy to hire for, so your own team can take the product over.
Can you build an MVP first and grow it later?
Yes. We scope a first version around the smallest set of features that lets real users complete a job, and we build it on the same standards as a mature product. That way it can grow into the full product without a rebuild.
Can you take over an existing web application?
Yes. We start with a code and infrastructure review, fix the most serious risks first, and then improve the system in stages while it stays in service. We recommend a rebuild only when the existing code cannot support what you need.
Who owns the code?
You do. The code, the infrastructure and the documentation are yours, in your own repositories and cloud accounts.
How much does a web application cost?
It depends on scope: the number of user roles, the workflows, the integrations and the compliance needs. After a short discovery call we send a written estimate with a fixed scope, so you know the cost before work begins.
