SERVICE 05 / APIS & PAYMENT SYSTEMS

APIs & payment systems
Connect your product.

Build reliable APIs and payment integrations that connect your product to the services it needs.

THE OPPORTUNITY

Disconnected systems and fragile integrations make everyday product workflows harder to maintain.

I map the data and payment flows, implement the integrations, and test success and failure paths with attention to security and reliability.

Connected services and maintainable payment workflows that support your product.

A good fit for

SaaS businesses and product teams building payment systems or connecting external services.

THE ENGINEERING PROCESS

Clear decisions at every stage of the product lifecycle.

Requirements, users and constraints.

Define the problem, map the key workflows, and agree on what success looks like.

System design, data models and technical decisions.

Choose the foundations, define service boundaries, and plan how the pieces connect.

Frontend, backend, integrations and infrastructure.

Implement the complete workflow, with validation, access control, and clear error handling.

Testing, deployment, monitoring and iteration.

Verify the release, deploy with care, and improve the product as it’s used.
