Services: Four ways to work together

Fromprototypetoproduction.

I take AI-built apps to production and build the software that’s missing. Every offer has scope, timeline and price agreed before we start.

Four offers.
One step at a time.

01

Your AI-built app, taken to production

Founders, startups and SMEs who built an app with Lovable, Bolt, Replit or similar tools. It works in a demo, but it isn’t ready for real users, real data and payments.

Step 1 — Audit72 hours · €450Step 2 — Fix & Launch1–3 weeks · from €2,000
Problem

AI tools get you to an app that looks finished very quickly. Underneath there’s often data anyone can reach, API keys exposed in the code, webhooks and payments nobody verified, no backups and no monitoring. The first real user, or the first error, becomes a serious problem.

  • Audit: security and stability review, a written report with issues ranked by severity, and a fixed-price quote to fix them
  • Data protection (database access rules, e.g. Row Level Security on Supabase) and safe key handling
  • Verification of webhooks, payments and external integrations
  • Staging and production environments, domain, backups and monitoring
  • 30 days of warranty after release
02

Business System

Companies of 5 to 100 people in professional and technical services, construction, distribution, manufacturing. Where the operational work runs on Excel, PDFs and email.

Timeline3–5 weeksPrice€3,000–6,000
Problem

A core process (quotes, orders, document handling, onboarding, reporting) is held together by hand across spreadsheets and inboxes. It costs hours every week, produces errors, and doesn’t scale. Off-the-shelf systems don’t cover that exact piece.

  • Process discovery with the people who actually run it, scope approved in writing
  • Data model and database (PostgreSQL / Supabase)
  • Web application with authentication, roles and permissions
  • API integration with 1–2 systems already in use, if available
  • Dashboard, team training and 30 days of bug fixing
03

Custom Software

Companies bringing a new digital product or a client-facing platform to market. Founders with an MVP to validate (including one built with AI tools that needs rebuilding on solid foundations), or agencies that have won a project beyond their technical capacity.

Timeline6–10 weeksPrice€6,000–12,000+
Problem

There’s no software on the market that does what’s needed. It has to be built from scratch, on an architecture that holds up as you grow instead of needing a rewrite in a year.

  • Extended discovery: requirements, user stories, MVP boundary
  • Architecture and data model documented before any code is written
  • Full-stack development: roles, permissions, core features, admin panel
  • Integrations with payments, email, storage, AI providers
  • Tests on critical flows, separate staging and production, monitoring
  • 60 days of bug fixing after launch
04

Website

B2B SMEs, professional practices and service companies with a dated site, or a first project alongside a new agency partner.

Timeline2–3 weeksPrice€1,500–3,000
Problem

The site doesn’t reflect what the company actually is, doesn’t generate qualified enquiries, and every edit depends on someone else. Credibility is lost in front of clients worth far more than the site.

  • Discovery and architecture: goals, sitemap, content structure
  • Bespoke design, not a recoloured template
  • Next.js development: performance, technical SEO, accessibility
  • Deploy, domain, analytics and 30 days of bug fixing after launch
After delivery

The system is yours. With every project I propose a maintenance plan, from €200 to €500 a month depending on the project: updates, backups, monitoring and fixes if something breaks. You can take it or leave it, but it’s already there in the quote.

How I work

Not every problem
needs software.

Get in touch if

Probably not if

  • Software already exists that does 90% of what you need. I’ll tell you, and save you the project.
  • You’re looking for branding, campaigns or social media.
  • The process changes every week and nobody has decided yet how it should work.
  • You’re looking for a developer at an hourly or daily rate: I only work per project, at a fixed price.

Let’s work

together
