Sectors

Your sector has specific problems. So do the solutions.

I build custom software and guide technology change in traditional and digital companies alike. Pick your sector to see which problems I solve, what I build and how I make the change actually stick.

Pick my sector or tell me your case

Which sector do you work in?

Do not see your sector? Problems look more alike than you think. Tell me how you work.

Two kinds of company, two ways of changing

Traditional company

Established processes, staff with years of craft and tools that "work" even if they cost hours. The challenge is not the technology: it is getting the change adopted.

  • I start with the process that hurts most, not with a big-bang migration.
  • I design with the people who will use it, not for them.
  • Old and new systems coexist until the new one proves its worth.

Modern company

Digital product, young teams and plenty of tools. The challenge is tidying what grew fast and making good technical decisions without slowing the business down.

  • Honest review of architecture, technical debt and risks.
  • Flexible technical leadership, without hiring a full-time CTO.
  • Team practices and documentation that last.

Lawyers, tax advisors, administrative agencies

Law firms and advisory practices

Deadlines, case files and documents scattered across emails, folders and spreadsheets.

Sound familiar?

  • Deadlines depend on someone's memory or a shared calendar.
  • The same brief, report or tax filing is assembled by hand every time.
  • Clients ask «where is my case?» and the answer lives in three different places.
  • Client data is split between the firm's software, Outlook and loose spreadsheets.

What I build

  • Case management with deadline control and automatic reminders.
  • Document and brief generation from templates and data already captured.
  • Client portal with case status and secure document exchange.
  • Internal assistant that answers questions about your own procedures and precedents.

How I manage the change. The firm already has a method. I digitise it as it works today and only change what is unnecessary, so nobody has to learn two ways of working at once.

Tell me about your case

Transport, warehousing, delivery, wholesale

Logistics and distribution

Orders, routes and incidents handled by phone, WhatsApp and spreadsheets.

Sound familiar?

  • Routes are planned by hand and redone every day because of last-minute changes.
  • Warehouse and invoicing do not talk to each other: data is typed twice.
  • Delivery incidents arrive by phone call and get lost.
  • Customers cannot see where their order is without calling.

What I build

  • Route planning by orders, zones and time slots.
  • Driver mobile app: route sheet, signed delivery note and delivery photo.
  • Warehouse management connected to orders and invoicing.
  • Integrations with your ERP, carriers and marketplaces.

How I manage the change. We start with the bottleneck that costs the most (usually routes or delivery notes) and go live quickly, with drivers and warehouse staff testing it from week one.

Tell me about your case

Workshops, factories, made-to-order production

Industry and manufacturing

Production, stock and costs you only see when the month is closed.

Sound familiar?

  • You do not know what an order really costs until it has been delivered.
  • Production orders are passed around on paper or by message.
  • Real stock never matches the system.
  • There is an old ERP nobody dares to switch off.

What I build

  • Production order tracking from a tablet or phone on the shop floor.
  • Stock control, traceability and cost per order.
  • Real-time production dashboards.
  • Connecting or replacing the legacy ERP in phases, without stopping the factory.

How I manage the change. There is no time for long training on the shop floor. Screens are designed with the people who will use them, and migration happens in stages: the old system keeps running until the new one proves itself.

Tell me about your case

HVAC, electrical, maintenance, refurbishment

Installation, construction and technical services

Site visits that end in quotes, certificates and work orders written by hand.

Sound familiar?

  • After every visit someone spends hours writing the quote.
  • Technicians fill in paper work orders that are retyped later.
  • Certificates and legal paperwork are late and full of errors.
  • Nobody remembers when each customer's next inspection is due.

What I build

  • Field app for technicians: visit, photos, materials and customer signature.
  • Quotes and certificates generated from the visit data.
  • Maintenance calendar with automatic customer reminders.
  • Invoicing and profitability tracking per job.

How I manage the change. Technicians decide whether this gets used or not. It is designed for the phone, with gloves on and no signal, and tested with them before anything changes in the office.

Tell me about your case

Online shops, distributors, marketplace sellers

Retail and ecommerce

Catalogue, orders and customer service spread across too many tools.

Sound familiar?

  • Product data is copied by hand between shop, marketplaces and ERP.
  • Photos and product sheets consume days of work.
  • The same customer questions arrive again and again.
  • Sales reports are assembled manually every week.

What I build

  • Catalogue, stock and order synchronisation across channels.
  • Automatic image processing and product data extraction.
  • Chat and assistants for customer service, answering from your catalogue.
  • Sales and margin dashboards that update themselves.

How I manage the change. We automate first what steals the most time and carries the least risk. The team keeps selling meanwhile, and every automation can be switched off if it does not convince.

Tell me about your case

Startups, digital products, growing teams

Tech companies and scale-ups

The product works, but it no longer scales and the team is firefighting.

Sound familiar?

  • Technical debt slows down every new feature.
  • Nobody makes architecture and technology decisions with a business view.
  • The team grows but the development process does not.
  • You depend on one or two people who know everything.

What I build

  • Technical review of the product and a prioritised clean-up plan.
  • Technical leadership by the hour or per project, without a full-time CTO.
  • Order in development process: code review, deployment and quality.
  • Building critical features alongside your team.

How I manage the change. The change here is about culture and method more than tools. I work side by side with your team, leaving behind practices and documentation that outlast my involvement.

    Small, usable deliveries, tested with your team from the start.

Frequently asked questions

My sector is not listed. Can you still help?

Yes. Problems repeat across sectors: manual processes, duplicated data, software that falls short. Tell me how you work and I will tell you honestly whether I can add value.

Do you work with both traditional and tech companies?

Both, and the approach differs. In a traditional company the hard part is getting people to adopt the tool; in a tech company it is tidying what already exists and deciding what to build. I have spent over 20 years in both worlds.

What exactly is technology change management?

Making a change of tools or ways of working actually work in practice: choosing where to start, involving the people who will use it, migrating without stopping operations and leaving your team self-sufficient. The software is the easy part.

Do I have to replace my current systems?

Not necessarily. Often the sensible option is to connect what you have, replace it in phases or leave it as it is. We decide together after I review it.
