Build an Idempotent Order API with Python and SQLite
Build a Python order API that survives a lost response and concurrent retries. Run the SQLite example, inspect saved orders and test conflicting keys.
ENGINEERING SERVICES
Build the customer workflow, backend and operating foundation for your next release.
Build the customer workflow, backend and operating foundation for your next release. We define the user, the information they need and the action they should be able to complete. The first release is scoped around a visible outcome that your team can review.
The delivery scope can include a customer-controlled repository, module and API documentation, sample configuration without secrets, migrations, test fixtures and a recorded handover. Third-party components retain their own licenses; ownership and reuse rights for custom work are agreed in writing.
I bring more than a decade in development and can take responsibility across the application stack. I lead the technical work directly. When design, QA or additional implementation capacity is useful, we agree collaborator roles and access as part of the project.
Pricing and delivery dates follow a review of scope, integrations and dependencies. A public blueprint is a starting point for that discussion, not an off-the-shelf package or a fixed delivery promise. Ongoing maintenance, hosting and external-service costs are scoped separately.
