TypeScript
TypeScript application experience in this portfolio spans complex retail workflows, payment adapters and commerce integrations. Explicit data shapes and state transitions help organize that application code.
Types plus runtime checks
Compile-time checks help developers catch incompatible changes. They do not validate an external API response or guarantee business correctness on their own. FULCRUM combines typed interfaces with runtime guards, scoped database operations, and regression tests for money and inventory behavior.
What I build with it
- Typed API and domain contracts
- Explicit payment and workflow state models
- Runtime validation at external and persistence boundaries
- Regression coverage for edge cases such as partial payments and preorder rounding

TypeScript application experience: planning a similar project
When an application connects several systems, the useful question is where a changing value first becomes trusted. A typed interface can describe an order, but the application still needs to check the data it receives. For an inherited codebase, identify the external inputs and the business rules that would be costly to break. FULCRUM provides a concrete example of that separation.
