Working in this sector

Financial products and advice can require specific authorization; use synthetic portfolio data, obtain written system access, and leave investment, credit, insurance, legal, and compliance decisions with appropriately qualified owners.

Skills that make the work valuable

  • Consent lifecycle integration
  • Bank data normalization
  • Financial event traceability
  • Authorized integration test design

Build proof, not just a list

Build a mock banking connector using synthetic accounts, covering expired consent, duplicate transactions, unavailable institutions, and clearly documented data-handling assumptions.

How to price this work as a freelancer

Define institutions, authorized APIs, consent flows, test cases, and support; exclude access to unapproved accounts. Agree the inputs, deliverable, review rounds, and acceptance criteria before quoting. Include preparation, specialist review, equipment or licensing costs, and handover time where relevant. Price ongoing support separately from the initial engagement.

Start with the income you need to replace

Required hourly rate = (target salary + benefits budget + annual business expenses) ÷ (annual billable hours × share of revenue retained after fees).

For illustration, $100/hour × 25 billable hours/week × 48 working weeks = $120,000 revenue. After $20,000 in business expenses, that leaves $100,000 profit before personal taxes. Replacing a $100,000 salary plus $15,000 in benefits under those assumptions takes $112.50/hour, with no percentage fees.

These are editable planning assumptions, not rates surveyed for open banking engineer work. Your personal taxes, location, contract terms, and workload still affect the comparison.

Compare the actual role scope, supervision, benefits, working hours, and access to tools with the cited occupation reference.

Running a freelance business

Independent specialists must price discovery, authorized access, synthetic testing, documentation, review gates, insurance, and ongoing support rather than treating financial workflows as ordinary configuration.
