One team

from scope to production

Aleksejs · Founder, CEO and AI architect

Step 1 · Design and build

One team builds it. Front to back.

Interface design and full-stack engineering from one team of developers, so nothing gets lost between the screen and the code. Tested, deployed and handed over to you.

The must-haves, the price and what live means, agreed in week 0.

One set of type, colour and components the product and the site both use.

Interface and flows in high fidelity. You see the real product before a line of code.

Front end, back end, API and billing logic, built to a production standard.

Payments, CRM, ERP and messengers wired in, so the product fits your business.

Performance and accessibility checked, then shipped to production in week 4.

Two weeks of support included, then an optional monthly care plan.

Next.js, Supabase, Postgres and Vercel. No proprietary lock-in to buy your way out of.

Why the product matters

Good product touches everything. Not just the website.

How customers sign up, how they pay, how your team runs the business and how investors judge the company. The product carries all of it. Durance designs and builds it as one piece, so every part holds up.

Step 2 · Week 0 to week 4

Four weeks to live. Every week has a job.

No drawn-out discovery and no surprises. Every week has an outcome you can see.

  1. Agree the scope

    WEEK 0

    You sign off the must-haves, what live looks like, and one fixed price before work starts.

  2. Set the system

    WEEK 1

    You approve the type, colour and components that every later screen is built from.

  3. Design every screen

    WEEK 1

    You approve real, clickable screens before the build starts.

  4. Build it

    WEEKS 2-3

    You get a working preview link with front end, back end and data, updated as it grows.

  5. Wire it in

    WEEKS 2-3

    You see your existing tools connected and checked against real data.

  6. Ship and support

    WEEK 4+

    Tested with you, deployed, and handed over with the keys.

Founder's note · Durance.dev

“A senior team designs your screens, writes your code and ships it. I set the architecture and answer for the outcome.”

No account managers, no handoff between agencies, no telephone game. One team of developers that owns the outcome, led by a founder who answers for it.
