Web Apps Development.
We design and codeup fast, secure web applications: SaaS products, customer portals, dashboards and marketplaces. They work in any browser, scale with your users and stay simple for your team to change.
CodeUp | Web Apps Development
Every kind of web product, built properly.
Whether it is your first release or the next version of a product with paying customers, we build with the structure to grow from the start.
Multi-tenant products with workspaces, roles, subscription billing, usage limits and an admin console, designed so one codebase serves every customer safely.
Secure areas where customers view orders, download documents, raise tickets and pay invoices, without calling or emailing your team.
Live reporting and analytics interfaces with filters, drill-downs and exports, built on fast queries rather than slow page loads.
Listings, search, bookings, messaging and split payments that connect buyers and sellers with trust and clear fees.
Back-office systems that replace spreadsheets: approvals, inventory, CRM-style records and reporting, with audit trails.
The right shape for your product.
Early choices decide how easy a product is to grow. We explain the options in plain language and recommend the simplest one that will last.
Server-rendered app
Pages are built on the server, so they load quickly and can be read by search engines.
Public products, marketplaces, anything that needs SEO
Single-page app
The browser loads once, then updates instantly as people work.
Dashboards, editors and tools used behind a login
Progressive web app
A web app that installs to the home screen, works offline and sends notifications.
Field teams and apps that must work with a weak connection
Modular monolith
One deployable application, organized in clear internal modules.
Most new products: simple to run and easy to change
Services and queues
Separate services and background workers for heavy or independent work.
Large platforms, heavy processing and high traffic
The parts every real product needs.
Built, tested and documented, so your launch is not waiting on plumbing.
Sign-in and permissions
Email, social and single sign-on, two-factor authentication and role-based access that decides who sees each page and record.
Billing and subscriptions
Stripe checkout, plans, trials, invoices, tax and webhooks that keep your database in step with what was charged.
Real-time updates
Live notifications, collaboration and activity feeds over WebSockets, so screens stay current without refreshing.
Search and reporting
Fast full-text search, saved filters, exports and scheduled reports built on well-designed queries.
APIs and integrations
Documented REST or GraphQL APIs, webhooks and connections to your CRM, accounting, email and analytics tools.
Email and file handling
Transactional email, secure uploads, image processing and long-running jobs handled in the background.
Start from scratch, or from what you have.
New product build
From idea to a live product. We scope the first release, design the screens, build in weekly increments and launch.
- MVPs and SaaS platforms
- Portals and marketplaces
- Internal tools and dashboards
Modernize and rebuild
Move a slow, fragile or outdated web app onto a modern foundation in stages, keeping the old version live until each part is ready.
- Legacy PHP, .NET or jQuery apps
- Single-page apps to server rendering
- Performance and security remediation
Dedicated team
Senior engineers and a designer who join your roadmap, work in your repository and follow your process.
- Monthly retainer for new features
- Code and architecture reviews
- Maintenance and upgrades
Code you will not be afraid to change.
Every project follows the same checks, whatever its size.
TypeScript throughout
Types run from the database to the button, so mistakes show up in the editor and not in production.
Automated testing
Unit and end-to-end tests run on every pull request, so releases are routine and not risky.
Core Web Vitals
We measure loading speed, responsiveness and layout stability before launch and after every release.
Security by design
Input validation, protected routes, secrets kept out of code and regular checks against the OWASP Top 10.
Accessibility
Semantic markup, keyboard navigation and sufficient contrast, checked against WCAG as part of the build.
Observability
Error tracking, logs and uptime alerts from day one, so we hear about a problem before your customers do.
Something you can click, every week.
Discover
We agree on users, goals and the smallest release worth shipping, and write the scope down.
Design
Flows and interactive prototypes tested with real users before any engineering starts.
Build
Weekly releases to a live preview link, so you see working features and decide what comes next.
Launch and grow
Go-live, monitoring, documentation and a team walkthrough. Support continues if you want it.
