Web Application Development Services
Most web application work is not greenfield. There is a system that still just about works, a spreadsheet quietly holding a department together, or a product that outgrew the platform it was prototyped on. We build the replacement without stopping the business that depends on the original.
Web Application Development done properly.
Different audiences, different failure modes. What they share is that the interesting problems are behind the interface.
- Customer-Facing & B2C Web Apps
High-traffic products where sign-up, checkout and page weight decide the revenue. Built to hold up on a mid-range phone over a poor connection, because that is the device and network most of your users actually have.
- B2B Web App Development
Portals, dashboards and ordering systems your customers log into. Tenancy, roles, audit trails and reporting are structural decisions here, so they are designed at the start rather than bolted on in the release before go-live.
- WordPress CMS Development
When the requirement genuinely is a marketing site with commerce attached, WordPress is the pragmatic answer. Done well means a maintained theme, a hardened plugin set and a real update path — not a page builder nobody dares touch.
Where this usually goes wrong.
Named up front, because avoiding them is most of the value.
- The legacy system nobody can switch off
A rewrite that needs a big-bang cutover tends never to happen. We plan for both systems to run side by side and for traffic to move across in stages, so a bad week stays reversible.
- Data older than the requirements
Twelve years of records that never quite matched the schema are why migrations slip. Profiling the real rows early costs days; discovering them over a cutover weekend costs the launch.
- Permissions invented one ticket at a time
An access model assembled per request becomes something nobody can reason about, and eventually an incident. Writing it down before the build is a day that saves a quarter.
- Traffic that all arrives at once
A platform proven by five internal testers behaves differently under a launch campaign. Load belongs in the architecture conversation, not the post-mortem.
The engagement, phase by phase.
Every phase is run by senior engineers and ends in something you can see.
Discovery and audit
We read the system you already have — schema, integrations, traffic, and the manual workarounds staff have invented — before proposing anything to replace it.
Architecture and access model
Data model, tenancy, roles and integration boundaries agreed and documented, because these are the decisions that are expensive to revisit.
Design and prototype
Clickable flows for the journeys that carry the business, tested with the people who will use them daily rather than the people who commissioned the project.
Build in vertical slices
Each sprint ships a complete feature, schema through interface, into a staging environment you can log into — so progress is something you use, not a percentage in a report.
Migration rehearsal
Extract, transform and load run repeatedly against copies of production until the dress rehearsal is dull. Then the real cutover is staged, timed and reversible.
Hardening and handover
Load and security testing, monitoring and alerting, runbooks, then repository and documentation handover to whoever operates it next — us or you.
Shipped, and still running today.
Four platforms in production. Two of them we still operate.
- EzGrocery →
An e-commerce platform with live order tracking, payment and SMS gateways, and automated reporting across three Canadian provinces.
- Caterday →
A two-sided marketplace on Angular and Node.js, with admin control over parameters, clients, suppliers and reporting.
- Inverge Journals →
A publishing platform we built and still run — persistent identifiers, harvesting endpoints and an editorial workflow that works.
- Insightful Journals →
A second platform, deliberately isolated from the first, with its production line rebuilt to publish four times as often.
What we build it with.
Chosen per project, and for what your team can maintain afterwards.
Questions we get asked.
Can you replace a legacy system without downtime?
Usually, by running old and new in parallel and moving traffic across in stages instead of flipping a switch late on a Friday. It costs more in planning and far less in recovery. Where a hard cutover genuinely cannot be avoided, we rehearse it against production copies until the timings are boring.
What happens to our existing data?
It comes with you, and it is normally the longest part of the job. We profile the actual rows early rather than the schema documentation, because that is where the surprises live. Migration scripts are written to be re-runnable, so the real cutover is a repeat of something already done a dozen times.
Do you build SaaS products with multi-tenancy?
Yes. Whether tenants are separated by row, by schema or by database is an early architectural decision with consequences for cost, isolation and every compliance conversation you will later have — so it is decided deliberately and written down. Our post on building scalable SaaS covers the trade-offs.
Will we be able to maintain it ourselves?
That is the intent. Conventional framework choices over clever ones, tests that run in your CI, infrastructure defined as code, and documentation written for the engineer who joins after we have gone. The repositories and cloud accounts are yours throughout, not just at the end.
Can you work alongside our in-house developers?
Yes, and it is often the better arrangement. Team extension puts our engineers inside your process and your repositories; a dedicated team runs delivery while your people stay close to it. Both models are described on our services page.
How much does a web application cost?
Scope, integration count and how much of the requirement is already settled drive it — not a rate card. Our consultation page sets out the six factors that move the number most, and a call turns them into a range for your project.
