Custom web development

When a website is not enough and you need the thing to actually work

Booking flows, catalogues with real logic, client dashboards, admin panels, integrations. Design and engineering by the same person, so the interface and the system are never arguing with each other.

  • from $12,000
  • 10–14 weeks
  • First concept in 5 business days
  • Fixed quote before the build

Who this is for

  • A no-code platform has hit its ceiling and you are fighting it instead of using it.
  • Your product needs accounts, roles or a dashboard, not just pages.
  • You have an internal process — bookings, orders, reservations — that lives in spreadsheets and messages.
  • You are pre-seed or seed and need a real MVP in front of users rather than a prototype in a design file.

What you get

  • A Discovery Sprint that produces requirements, architecture, a backlog and a realistic budget range
  • Interface design for the flows that matter, not a deck of screens nobody builds
  • Front-end and back-end development, database, authentication and roles
  • Admin panel for the people who will run this daily
  • API integrations with the systems you already use
  • Testing, monitoring, deployment pipeline and documentation
  • Repository access and code ownership from the first commit
  • Milestone-based delivery: you see working software every two weeks, not at the end

What it does not include

  • Native iOS and Android applications
  • Machine learning and data science work
  • Regulated fintech, medical or payment infrastructure requiring certification
  • 24/7 on-call operations — monitoring and response are covered by a care plan with agreed hours

How it runs

Discovery Sprint

1–2 weeks

Paid, from $900, and credited against the build. Output: requirements, architecture, backlog, prototype and a budget range you can take to anyone — including someone else.

Design

2–3 weeks

The flows that carry the product: sign-up, the core action, the admin view. Designed against real data shapes, not placeholder text.

Build

6–10 weeks

Two-week increments with something working at the end of each. Scope changes are quoted before they are built, never after.

Launch and care

1–2 weeks

Deployment, monitoring, documentation, handover. Then a care plan or continued development, whichever the product needs.

  • Fixed scope and fixed price agreed before the build starts
  • A defined number of revision rounds — no vague “unlimited”
  • 50% deposit on small projects, milestone payments on larger ones
  • Full rights, source files and accounts transfer on final payment

Questions

Why does it start with a paid Discovery Sprint?

Because a fixed price on an undefined product is either padded or wrong. from $900 buys requirements, architecture, a backlog, a prototype and a credible budget range — and it is credited against the build if we continue. If we do not, the documents are still yours.

Can one person really deliver this?

For the scope described here, yes — that is exactly the founder-led model, and it removes the coordination cost that makes agencies expensive. For work that genuinely needs a team, I say so during Discovery and we scope it accordingly rather than stretching a solo timeline.

How is it priced?

Discovery is fixed. The build runs from from $12,000 on milestone payments — you pay against delivered increments, not against a promise. For products that keep evolving, time and materials on two-week sprints is usually more honest than a fixed price.

Who owns the code?

You do, from the start. The repository is in your account or transferred to it, licences are documented, and there is no proprietary layer that only I can maintain. Handing the project to another developer should be boring, not a hostage negotiation.

What technology do you use?

Typically React and Next.js on the front end with Node and Postgres behind it, deployed on managed infrastructure. The stack is chosen for what your team can maintain afterwards, and it is named and justified in the Discovery document before you commit.
