For your business

  1. Paper sheets showing a path with a magnifying glass over a point of attention
    01

    Business diagnosis

    Before writing any code, I sit down with your team and look at how the company works today: where time is lost, where customers slip away and where revenue is left on the table.

    Before
    A feeling that something isn’t working
    After
    A clear plan, with priorities and costs
  2. A paper process connected by threads to a software interface

    Custom software

    I build exactly what your company needs, around the way it already works. No paying for features nobody uses, no bending your team to fit generic software.

    Before
    Generic software that doesn’t fit
    After
    A tool made for your business
  3. A paper clock with tasks being absorbed into a software window

    Fewer hours wasted

    Invoices, emails, reminders, reports and customer replies start happening on their own. Your team drops the repetitive work and focuses on what brings results.

    Before
    Hours every week on manual tasks
    After
    Processes that run themselves
  4. Paper coins gathering into a stack

    Bring in more revenue

    A website that shows up on Google, easy payments and automatic follow-up with every customer at the right moment. More enquiries, more sales and fewer forgotten opportunities.

    Before
    Customers lost along the way
    After
    More enquiries and more sales

What I do

How I work

Every phase ends with something you can use. You always know what’s done, what’s left and what it costs.

  1. 01

    Diagnosis

    I look at how the company works today and where time and money are lost, before talking about technology.

  2. 02

    Proposal

    Scope, timeline and cost agreed in writing, split into phases.

  3. 03

    Build

    Weekly deliveries you can use, not slide decks.

  4. 04

    Launch

    Release, measurement and support once it’s in production.
