/// 05 How we work together // four steps. no surprises.
step.01

Discover

A short call (or DM thread) to scope the project, the audience, and what success looks like. Honest answers — including whether it's the right project for me.

step.02

Plan

Fixed quote, clear timeline, plain-English brief. No surprise line items, no agency double-speak.

step.03

Design & Build

Iterative builds with previews you can click. Feedback loops are short, code is clean, and the work stays visible end-to-end.

step.04

Launch & Grow

Deploy, instrument, and tune. SEO and analytics wired in so you know what's working — plus aftercare so it stays that way.

Sean rebuilt our site in three weeks and it's quietly outperformed every agency redesign we'd paid for before. Communication was the best part — clear, direct, no jargon.

We went from an idea on a napkin to a real iOS app in the App Store. Sean treats your project like it's his own and pushes back when an idea won't actually serve users.

Our organic traffic tripled in six months and we finally rank for the searches that actually bring customers. Worth every penny — and he explained every change so we learned along the way.

/// 07 Frequently asked // answers, plainly
What does a typical project cost?
It depends on scope, but as a rough guide: simple business websites start in the low four figures, custom builds and e-commerce sit in the mid range, and full app builds are quoted on a per-project basis. Every quote is fixed and itemised before any work starts — no surprises, no hourly drift.
How long does a build take?
A typical business website lands in 2–4 weeks. Custom web builds run 4–8 weeks. Mobile apps are usually 8–16 weeks for an MVP. I only take on a small number of projects at a time, so once we've agreed a start date, your slot is yours.
Do you work with agencies and freelancers?
Yes — I white-label development for design studios and consultants who need senior engineering hands without growing headcount. Discreet, on-brief, on-deadline, and your client never has to know I exist.
Will I own the code and the accounts?
Always. The repository, hosting, domains, analytics and ad accounts are yours from day one. I'll set them up under your ownership and hand over clean access. No vendor lock-in, ever.
What about ongoing support?
Every launch includes a 30-day aftercare window for fixes and small tweaks. Beyond that, I offer monthly retainers for clients who want a steady hand on the wheel — performance monitoring, content updates, SEO maintenance, and small feature work.
Can you take over a half-built project?
Often, yes. I'll review the existing codebase honestly and tell you whether it's worth continuing or rebuilding. If we continue, I document and stabilise what's there before adding anything new.
How do I get started?
DM me on Instagram @codebysean with a few sentences about your project. I'll come back within 24 hours with either a quote, a few clarifying questions, or — if it's not the right fit — an honest pointer to someone who'd serve you better.
