Hagolf
Golf scoring for societies and friends
Score a hole for a four-ball in under a minute, even with no signal. Keep a league running with your friends and walk off the 18th with a poster for the group chat.
Now testing Have a Gander, movie taste shared with friends
Hagworks is the one-person software company of Maurits van ’t Hag. I design, build and run my own web and mobile apps, and take on projects for others: custom software, data analysis and smarter workflows.
01 The apps
Each app has its own home, its own support address and the same care. One is out in the world, two are on the bench.

Knows your taste. Settles movie night.
Rate what you watch in two taps. It learns what you love, tells you what you’ll make of a film before you press play, and helps you and your friends pick one.
Hungry, grumpy, and no idea what to eat?
Works out what you’re actually in the mood for, then helps with the next question: cook it yourself, or go out for it.
02 Approach
No growth hacks, no dark patterns. Software that does one job well and keeps doing it.
No ad networks, no tracking pixels. Each app keeps what it needs to work and nothing more, and says so in plain language.
Offline-first where it matters. Hagolf scores a full round on a course with no signal and catches up when it finds one.
The person who designed it answers the support mail. Every app has its own support address, and it lands with me.
Plain, fast web technology on Cloudflare’s network. Small pages, quick loads and few moving parts to break.
03 Work
Apps, data and the processes around them. The same tools and standards as my own apps, for your project.
Installable, fast and usable offline. One codebase for phone and desktop.
iOS and Android from one React Native codebase, through to the store listing.
Spreadsheets, exports and databases turned into clear answers, reports and dashboards you can act on.
Find where the hours go, then cut the copy-paste and manual steps with automation and small tools.
Landing pages and company sites like this one: quick, accessible, no cookie banner needed.
Domains, email, sign-in and hosting on Cloudflare and Google Workspace, done properly.

Hagworks is my company: one person who designs, builds and looks after software. I started it to give my own apps a proper home, with their own domains, support addresses and legal pages, and the same standard applies to the work I do for others.
Based in the Netherlands, working in English and Dutch.
