Freelance developerLisbon
2 clients at a time, never 3. Most come from the last one.
Senior engineerTidewater Freight, Rotterdam
Owned search and the shipment API. Left the on-call doc better than I found it.
DeveloperPaper Lantern, a 6-person studio
Built 31 sites for shops and clinics, and learnt to ask what they were for.
How I work
- I ask for the number first. If nobody can name one, we find it before I write code.
- You get a working link on day 5, and a new one every Friday after.
- The handover doc is written as I go, not in the last week.
- You hear back the same day. That is why there are only 2 of you.
Keep the tab. Or send an email.
Tell me the number you want to move and who is asking. I reply the same day, from Lisbon time.
