Shipping backend features without losing the plot

Notes on scopes, boundaries, and the boring parts that keep services healthy.

Most production issues are not missing features — they are unclear boundaries, surprise coupling, and invisible operational load.

A practical checklist

  1. Write the happy path as a sequence diagram (even a rough one).
  2. Name your failure modes — timeouts, partial writes, duplicate events.
  3. Instrument first: structured logs + one metric that proves the feature works.

Example SQL snippet

select id, status, updated_at
from missions
where status = 'active'
order by updated_at desc
limit 50;
