Custom web applications — built for production.
When a website isn’t enough. We build full-stack web applications — SaaS dashboards, booking platforms, client portals, and internal tools — engineered for real scale with real users.
What we build
Every kind of web application — engineered end to end.
From an MVP you can validate in a month to a full SaaS platform with billing, multi-tenancy, and a production-grade infrastructure stack.
01
SaaS Application Development
Subscription-based products with multi-tenancy, role-based access, billing integration, and an admin panel. Built to onboard real users on day one.
02
Booking & Scheduling Systems
Custom booking engines with live availability, payment collection, calendar sync, automated notifications, and conflict management. Our speciality — we’ve built many.
03
Client Portals & Dashboards
White-labelled portals with role-based access control, document management, reporting, and audit logging. Replace the email inbox with an actual product.
04
Internal Tools & Admin Systems
Replace spreadsheets and Zapier chains with a purpose-built web app. Faster for your team, more reliable, fully owned, and actually fits how you work.
05
REST API & Backend Development
Node.js or Laravel APIs, database design, third-party service integrations, webhook handling, and API documentation. Clean, versioned, and properly tested.
06
Database Architecture
PostgreSQL or MySQL schema design, indexing strategy, query optimisation, migration management, and caching with Redis. Gets you to scale before it becomes a problem.
Technology
A modern, prove full-stack.
No trend-chasing. Every tool in our stack is production-proven, well-maintained, and has a large community. We choose for reliability and developer ergonomics — not hype.

Free scoping · 24hr response
Free project scoping call
A 45-minute discovery call to map your application requirements, technical constraints, integration needs, and the fastest credible path to a working product. We’ll tell you honestly what’s in and out of scope for your budget, and flag the things that tend to blow up web app projects.
Feature list prioritised by value and complexity
Honest scope and timeline estimate
Tech stack recommendation with rationale
Red flags and risk areas identified upfront
Web App Estimate Request
Written breakdown within 24 hours. No pitch call required.
how it works
From discovery call to production app.
Discovery
Map user flows, data model, third-party integrations, auth requirements, and non-functional requirements (performance, uptime, compliance). The detailed brief that prevents scope creep.
Architecture
Database schema, API design, authentication model, infrastructure plan, and deployment strategy. Documented and reviewed before any code is written.
Design
Figma wireframes and full UI design — every screen, every state. Approved before development begins so build is a translation, not an interpretation.
Build
Sprint-based development with working feature demos every 1–2 weeks. Staging environment throughout. You see real progress, not a big reveal at the end.
QA & Security
Automated tests for critical paths, manual QA across browsers and devices, security audit (auth, input validation, injection prevention), and load testing.
Deploy & Scale
Production deployment with CI/CD pipeline, uptime monitoring, error tracking (Sentry), and infrastructure documentation. Zero-downtime deploys from day one.
Pricing
Transparent pricing. No surprises.
Fixed-scope projects with staged milestones. Complex projects scoped after the free discovery call.

FAQ
Questions we hear every week.
What kind of web applications do you build?
Booking and scheduling systems, SaaS dashboards, client portals, CRM tools, inventory management systems, marketplace platforms, internal operations tools, and data reporting apps. If it's a multi-page interactive product with a database behind it — rather than a marketing site — that's a web application and we build it.
Do you handle the backend too, or just the frontend?
Full-stack — one team for everything. We design the database schema, build the API, set up authentication, handle third-party integrations, and build the frontend UI. You get a single point of contact and a codebase that was designed end-to-end, not stitched together by separate teams.
What's your tech stack?
React and Next.js on the frontend, TypeScript throughout. Node.js or Laravel for the backend API depending on the project's needs. PostgreSQL or MySQL for the primary database, Redis for caching and queues. Deployed on Vercel, Railway, or AWS depending on scale and budget. We choose what fits the project — not what we're most comfortable with.
How do you handle authentication and security?
We use NextAuth, Clerk, or Auth0 — proven, well-maintained libraries, not rolled-from-scratch auth. Every app ships with HTTPS, parameterised database queries (no SQL injection), CSRF protection, rate limiting on API routes, input validation on both client and server, and proper environment variable handling. Security is not an add-on.
Can you set up Stripe subscription billing?
Yes. Stripe Billing for subscriptions, usage-based pricing, and invoicing. Includes plan management (upgrade, downgrade, cancel), trial periods, webhook handling for payment events, and a billing portal so customers can manage their own payment methods. We've implemented Stripe billing across multiple SaaS products.
What does handoff look like after the build?
Source code in your Git repository. Deployment documentation covering environment variables, infrastructure, and CI/CD pipeline. A Loom video walkthrough of the codebase for your team or future developers. 30 days of post-launch support included. After that, a retainer or Care Plan is available for ongoing development and maintenance.
