Next.js development and custom AI builds for dashboards, client portals and product platforms
When a product needs logins, live data and logic of its own, a website builder runs out of room. Desses designs and builds the real thing in Next.js and React, with design and development in one flow, so nothing gets approximated on the way from the Figma file into the finished product.

From product direction to a shipped build, moving through scope, architecture, interface and launch across six structured weeks
Product goals, designs and technical requirements turn into a working Next.js application your team can launch, maintain and extend. Six weeks is the usual shape, grouped into four steps. Every step closes with something you can look at.
01. Technical Direction
You get a fixed price before a single line of code exists.
Desses goes through the product, the goals, the designs, the data, the integrations, and what the build has to support six months after launch. Most of this step is questions, and the sharp ones are usually about the parts you haven't decided yet. What comes out is a scope you can hold someone to, with a number attached.
02. Architecture and interface
The expensive decisions get made while they're still cheap, and by the end you're clicking through real screens.
Data model, routes, authentication and component structure come first, because these are the choices that cost an afternoon now and a fortnight in month three. The repo and deployment pipeline get set up in the same pass, so everything after this is visible on a live URL. Design and frontend then run together, which means there's no stage where a static frame gets handed over and quietly changes shape on the way into code.
03. Product logic
The states nobody demos are the ones that decide whether it feels finished.
Roles, permissions, edge cases. Loading, empty, error, partial. A product that only works in the happy path is a prototype with good lighting, and this is the step where that gap closes. Validation, error copy and permission boundaries get written here rather than patched in after a user finds them.
04. Integrations, launch and handover
Every connection gets a failure path, and you leave with the repo, the deployment and the documentation.
Payments, model endpoints, internal APIs, webhooks, CMS. The connecting is the fast part. The work is in rate limits, retries, timeouts, and what a user actually sees on screen when a third party is down at 2am. Integrations are where most products break first, so the QA pass lands here too. Then it ships. Deployed on your infrastructure, repo in your organisation, no licence tied to Desses. A walkthrough call covers how it's put together and where to change what, followed by written handover notes. The standard those notes are written to is simple: a developer who has never met me should be able to pick it up and ship a feature without asking a question.

Frontend architecture
Routes, components, layouts and states planned before the build turns into a pile of one-off files.
React components
A reusable set covering pages, dashboards, product flows and custom interfaces, so feature two costs less than feature one.
API and AI integrations
The frontend connected to APIs, auth, CMS, payments, model endpoints and product data, with the failure paths handled.
Product logic
Custom flows, user states, roles, permissions and interactions built around how the product is actually used.
Performance and technical SEO
Fast loading, clean semantic structure, responsive layouts, and the schema and heading discipline that gets a product read by AI answer engines.
Developer handover
A Next.js setup your team can read, maintain and extend. Organised files, written notes, no dependency on Desses.
Custom builds need more than working code
A prototype proves the idea. A product needs clearer flows, safer logic, better states, and fewer surprises when real users touch it. Six things go into every build.

One studio, seamlessly connecting design and development so nothing gets lost between the drawing and the finished product
Most product quality dies in the gap between the designer and the developer. At Desses there's no gap, because it's the same person on both sides. You work directly with me from the first call to the handover.
Design and engineering stay in one head
A messy MVP is rarely only a design problem or only a code problem. Flows, components, logic, data and implementation get looked at together, because they arrive together.
Products people trust
Unclear buttons, no feedback when something works, broken screens, inconsistent design, logic that falls over. These are what make software feel unfinished, and they're the first things a dev-only team drops when the deadline tightens.
Only what needs rebuilding gets rebuilt
Some parts get redesigned. Some get properly rebuilt in React or Next.js. Most of it usually stays. Throwing away working code is expensive and rarely necessary.

Not sure which plan fits yet?
That’s okay. Everything you need to know before choosing a plan
How does the subscription work?
You subscribe to a monthly plan and submit requests through a shared workflow (Slack + Notion). Requests are handled one at a time, with clear turnaround times depending on the plan. Simple, focused, and predictable.
What kind of requests can I submit?
Anything across product design, UX and UI, AI platforms, portals and automations, and Framer development. From landing pages and flows to client portals, dashboards, components, and improvements to what you already run.
How fast will I receive updates?
• Growth plan: updates every ~48 hours • Startup plan: updates every ~24 hours More complex requests may take longer, but you’ll always see steady progress.
Is there a limit to how many requests I can make?
You can submit as many requests as you want. They’re delivered one by one, so focus stays high and quality doesn’t drop.
What if I only need you for a short time?
That’s fine. You can pause or cancel your subscription anytime. No long-term commitment — use it when you need it, pause when you don’t.
What if I don’t like the direction?
No stress. We iterate together. Feedback is part of the process, and we refine until the result feels right and works for your goals.
Who will I work with?
You work directly with Oskar, the founder. No outsourcing, no handovers. One point of contact, full ownership, and clear communication throughout.
How do we communicate?
Whatever works best: Slack, Notion, Loom, or short calls when needed. The goal is clarity, not meetings for the sake of meetings.
What is the Fast Turnaround option?
A focused, project-based engagement to deliver a specific outcome — like a landing page, feature, or website refresh — from UX to final Framer build.
Is Fast Turnaround better than a subscription?
It depends. • Choose Fast Turnaround if you have one clear goal and want it shipped fast. • Choose a Subscription if you expect ongoing work, iteration, or growth. If you’re unsure, we’ll figure it out together.
Can Fast Turnaround turn into a subscription?
Yes. Many projects start focused and then move into a subscription for iteration and growth.
If you want to start a project, explore a collaboration, or simply talk things through — this is the easiest place to begin.
