Full Stack Web Application Development
React or Next.js on the front end, Node.js or Python behind it, PostgreSQL underneath, deployed to the cloud, and one team responsible for all four layers from kickoff to launch.
Full Stack Development
One Team Builds Your Whole Application
Frontend, backend, database and deployment, built by the same engineers from day one. No handoffs, no integration surprises, no finger-pointing when something breaks.
- React + Node.js
- One Team
- End-to-End
- Fully Documented
The cost of split teams
Why do frontend and backend keep drifting apart?
Most delays and post-launch bugs trace back to the space between separate frontend and backend teams. Put one team in charge of the whole stack, and that space closes.
06 friction points we design out of every build
- 01
Two teams, two sets of assumptions
When the API changes without warning the interface, or the interface assumes data the API never sends, you get bugs that neither team claims. One team building both closes that gap.
- 02
No single owner for the whole system
Split the frontend and backend across two vendors and you get handoffs, blame-shifting and integration failures. One team accountable for the entire stack is accountable for the entire result.
- 03
APIs that do not match what the UI needs
An API designed without the interface in mind over-fetches, under-fetches, or hands back data the client has to reshape at cost. We design the contract from both ends at once.
- 04
End-to-end delivery is hard to find
Frontend shops stop at the API boundary. Backend shops stop at the interface. A team that does both well, and ships a finished product, is genuinely uncommon.
- 05
Integrations fail in the space between specialists
Third-party integrations that touch both layers are where most bugs live. One unified team handles them start to finish, with no handoff risk in between.
- 06
Handoffs slow down every release
Cross-team reviews, waiting on API updates and bugs from misaligned assumptions all add latency without adding value. Fewer handoffs means faster ships.

What we build
Full stack services, one team deep
From SaaS platforms to internal tools, every build is owned end to end, by the people who wrote the code and who will still be here after launch.
SaaS Product Development
From first MVP to a platform that scales: multi-tenant architecture, subscription billing, user management, usage tracking and the admin tools to actually run the business.
API + Frontend Development
We design the backend contract and the frontend interface together, so the data shape fits the screen from day one instead of getting patched after the fact.
Database-Driven Web Applications
Applications built on a schema shaped for the queries your product actually runs, not a generic structure retrofitted once the reporting requirements show up.
Admin Dashboard & Portal Development
Role-based access, data tables, charts and the CRUD screens your team needs daily, built into internal tools and customer portals alike.
Real-time Application Development
Live collaboration tools, streaming dashboards, notifications and chat, built on WebSockets with backend infrastructure sized to hold the connection load.
Customer-Facing Web Application Development
Product-grade applications your customers use every day: fast, accessible, tested on real devices and built to handle the edge cases that actually show up in production.
Internal Tools & Workflow Automation
Custom software that replaces the spreadsheet-and-email workaround: inventory tools, approval workflows, reporting dashboards and the integrations between them.
E-commerce Full Stack
Custom commerce builds for what Shopify and WooCommerce cannot handle: headless storefronts, custom checkout flows, B2B portals and marketplace platforms.
Legacy System Modernization
Migrate off monolithic PHP, aging .NET or an outdated Node.js codebase onto a modern, documented, tested full stack, without stopping the business to do it.
DevOps & Deployment Pipeline
CI/CD pipelines, container orchestration, environment configuration, migration scripts and the infrastructure that makes every release boring and repeatable.
Ongoing Full Stack Maintenance
The team that built it maintains it: updates, security patches, new features and incident response from people who already know every layer of the system.
Why choose us
Built by one team, end to end
When a single team designs, builds and ships the whole system, integration problems disappear and delivery speeds up. These are the standards we hold every full stack engagement to.
Start your project-
One codebase, one team
The same engineers write your frontend and your backend, to the same standards. No handoffs, no integration surprises, no blame gaps between vendors.
-
The contract is designed both ways
We shape the API and the interface together, so the backend returns exactly what the frontend needs, in the shape it needs it, the first time.
-
Fewer handoffs, faster releases
Removing the handoff between separate frontend and backend teams removes the single biggest source of integration delay and post-launch bugs.
-
Architecture we own and stand behind
We make the technology calls, document the reasoning and maintain them. You get a system with a coherent architecture, not one that grew by committee.
-
Tests that cross the whole stack
Unit tests, integration tests and end-to-end tests that cross the frontend-backend boundary, so your suite validates the full system, not just its parts.
-
DevOps built in, not bolted on
Deployment pipelines, environment management and infrastructure-as-code are part of project scope, not an afterthought someone else has to configure later.
-
Scale planned in from day one
We make the scaling decisions early, while they are cheap, instead of after the system is under load, when they are expensive to unwind.
-
One number to call, always
One conversation fixes any problem: a frontend bug, a backend error or a deployment issue. No ticket routing between vendors who each own half the stack.
How we work
Our full stack development process
Eight stages, each with something concrete you can see and sign off on, from the first architecture doc to the monitoring dashboard on launch day.
- 01
Discovery
We map your product goals, user journeys and technical constraints before any design work starts.
- 02
System Design
Architecture, technology choices and the data model, agreed and documented before a line of code is written.
- 03
Database Schema
A schema shaped by normalization, indexing and the query patterns your product will actually run.
- 04
API Development
The backend API built contract-first, with tests, so the frontend always has a stable surface to build against.
- 05
Frontend Build
The interface built against the real API in short cycles, with a working demo you can click through every week.
- 06
Integration & Testing
End-to-end tests that walk the full user journey across frontend, backend and database together.
- 07
Launch
Production deployment through the CI/CD pipeline, with monitoring and a rollback path in place before go-live.
- 08
DevOps & Monitoring
Logging, error tracking, uptime alerts and performance dashboards, configured and documented for your team.
What is included
One team versus two separate teams
The cost of running two separate teams is not just the invoices. It is the integration bugs, the delayed releases and the feature that fell through the gap between teams.
What you get Two separate teams WebNX

API designed with UI in mind
Single point of accountability
No handoff friction between layers
Shared codebase standards
End-to-end test coverage
Integrated CI/CD pipeline

Client words
Trusted by teams building real products
We went from idea to paying customers in fourteen weeks. One team, one set of daily standups, one invoice. The product is clean, fast and our users actually enjoy using it. That is rare.
We had separate frontend and backend agencies before. The integration bugs between them cost us more than hiring a single team would have. We switched to WebNX and shipped the next version in half the time.
They built the patient portal, the admin dashboard and the API that connects them in ten weeks. Everything works together because the same people built everything. We have had zero integration issues since launch.

Questions, answered
Full stack development FAQs
How much does full stack development cost?
It depends on the scope, complexity and functionality required. A focused MVP or internal tool is typically simpler, while a full SaaS product with complex business logic, multi-tenancy and DevOps requires more investment. Every project is scoped and quoted individually before work begins.
What does full stack mean for our project?
Full stack means one team designs, builds and deploys the frontend (what users see), the backend (the APIs and business logic), the database (where data lives) and the deployment infrastructure. You get one team accountable for all of it.
What technologies do you use?
We typically use React or Next.js on the frontend, Node.js or Python on the backend, PostgreSQL or MongoDB for data storage, and AWS or DigitalOcean for hosting. We choose based on your requirements and the team who will maintain the system after we hand over.
Can you take over a project another team started?
Yes. We start with a short paid audit so you get an honest assessment of the existing code before we make any promises. Then we plan whether to extend, refactor or rebuild based on what we find.
How do you keep frontend and backend in sync?
By having the same team build both. We design the API contract at the start with both the frontend and backend requirements in mind, use TypeScript end to end where possible and write integration tests that cross the boundary.
How long does full stack development take?
A focused web application or internal tool takes 6 to 10 weeks. A full SaaS product with multiple user roles, billing and integrations runs 12 to 24 weeks. We provide weekly demos so you see progress throughout.
Do you handle deployment and DevOps?
Yes. CI/CD pipelines, container orchestration, environment variables, database migration scripts and monitoring setup are part of every full stack project scope. You get a production environment that is reproducible and documented.
Do you write tests across the whole stack?
Yes. Unit tests for business logic, component tests for the UI, integration tests for API endpoints and end-to-end tests that run the full user journey. Coverage is agreed at scoping and is a deliverable requirement.
Can you build a SaaS product?
Yes. SaaS development is one of our most common full stack engagements. We handle multi-tenancy, subscription billing (Stripe), user management, usage tracking, admin dashboards and the scalable architecture needed to grow from ten users to ten thousand.
How do you manage scope in a full stack project?
We document scope in a written specification before work begins. Changes go through a clear change request process with a timeline and cost impact assessment. We do not absorb scope creep silently and then surprise you with an overrun.
Do you do ongoing maintenance?
Yes. The same team that built the system maintains it. We offer retainers for ongoing development, security updates, dependency upgrades and incident response. Having the original team on-call is faster than onboarding someone new.
What happens after launch?
We provide documentation, architecture diagrams, a deployment runbook and a handover session. Most clients stay on a maintenance retainer. We are still reachable for the next version, not just during the initial engagement.
