Most agencies staffing a PostgreSQL project add a layer of account management and bench-time cost you never see broken out. Here you talk to the person who will actually write the PostgreSQL code, agree scope with them directly, and pay only for the hours that produce the work.
A profile only appears here after we have checked commercial PostgreSQL track record, looked at real production code the person has shipped, and confirmed they can explain their technical decisions in plain language.
Work booked through this page ranges from a single fixed task — a broken integration, a migration, one feature — to an ongoing part-time arrangement. There is no minimum engagement and no bidding process.
Describe your project with the form above and you will typically see three to five verified PostgreSQL specialists within a couple of hours.
Yes — a large share of the work booked here is a single fixed task, not a long-term contract.
Rates are set by each independent engineer and shown on their profile. You agree scope and price directly with them, with no platform markup.
