Web Apps & Custom Development

When off-the-shelf software stops fitting, we build the web app that does — fast, secure, and shaped around how you actually work.

Some problems do not have a plugin. When your workflow is the product, when the dashboard your team lives in is glued together from five tools that half-talk to each other, you need software built for the job. We design and develop custom web apps — portals, internal tools, booking systems, SaaS products, data-heavy dashboards — that load fast, scale cleanly, and bend to your process instead of bending it to theirs.

What's included

What you get

Discovery and technical scoping: user flows, data model, and a written spec you sign off before a line of code is written

Custom front end tuned for speed — interactive interfaces that stay under a 2s load even with heavy data

Back-end, database, and API work: secure auth, role-based access, and clean integrations with the tools you already use

Third-party and payment integrations — Stripe, CRMs, accounting, shipping, whatever your stack needs to talk to

Testing, accessibility checks, and staging review so you see and approve the real thing before launch

Post-launch care: monitoring, fixes, and a documented handover so nothing lives only in our heads

How we work

Our approach

No mystery, no busywork — a clear sequence that gets you a result you can measure.

01

Scope before code

We start with the problem, not the framework. A short discovery phase maps your users, your data, and the one or two outcomes that justify the build. You get a written spec, a flow diagram, and a fixed scope — so everyone knows what 'done' looks like before estimates turn into invoices.

02

Build in working slices

We ship the app in functional pieces, not one big reveal at the end. You see a real, clickable version early and review progress every week. That keeps the build honest, surfaces wrong turns while they're cheap to fix, and means the thing we hand over is the thing you actually asked for.

03

Engineered for speed and scale

Performance is a build decision, not a polish step. We choose the stack for the load, lazy-load what isn't needed yet, index the database properly, and cache where it counts. The result is an app that feels instant on day one and still does at ten times the traffic.

04

Launch, measure, maintain

We deploy to a staging environment first, test under real conditions, then go live with monitoring in place. After launch you get documentation, code you own outright, and a care plan if you want one — so the app keeps running fast and secure long after handover.

FAQ

Questions, answered

How long does a custom web app take to build?
It depends on scope, but a clear pattern holds. A focused internal tool or portal typically runs 6–10 weeks. A larger product with payments, multiple user roles, and integrations runs 12–20 weeks. We give you a phased timeline after discovery, with weekly check-ins so you always know where the build stands — no silence followed by a surprise.
How do you price custom development?
We scope first, then quote. Once discovery defines the spec, you get a fixed price for that scope so there are no open-ended hourly bills. If the project is genuinely exploratory, we'll propose a discovery phase as a small fixed-fee piece on its own, so you can decide on the full build with real information in hand.
What do we need to provide to get started?
Less than you'd think. We need access to anything the app must connect to — your CRM, payment account, existing data — plus one decision-maker who can answer questions and sign off on each phase. If you have wireframes or a feature list, great; if you have a problem and no plan, that's what discovery is for.
How do you measure whether the app actually works?
Against the outcomes we agreed in scope, not vanity metrics. That might be load time under 2 seconds, a task that took 20 minutes now taking 2, fewer support tickets, or a clean conversion path. We instrument the app so those numbers are visible, then review them with you after launch — and fix what the data tells us to.
