Here is my schema:

```sql
CREATE TABLE article_to_warehouse (
  article_id   INTEGER
, warehouse_id INTEGER
)
;
```

How do I add a `UNIQUE` constraint?

Beginning of next year I am setting out as an independent software engineering consultant. As such I am interested in hearing from others who have already done something similar! I have been working as a developer and team lead for more than 10 years of which the last 5 have been focused mostly on the .Net stack. Now I want to expand my horizons a bit more, preferably with a new domain or another tech stack.

What are some suggestions/advice you'd give someone just starting down this path? Anything I should avoid doing? Anything I should definitely do? I suppose the specifics will vary a bit by country, but are there some general things I should be thinking about?

Oh, if you happen to have a need for a senior developer/tech lead, give me a ping!
