OVERVIEW
Context
The engagement began before an implementation approach had been selected. I worked from business and operational requirements through system and data-flow mapping, architecture, implementation planning, hands-on development, testing, documentation, production readiness, and delivery.
PROBLEM
What had to be solved
Brokerage back-office, accounting, and banking systems held related financial and operational data but were not designed as one workflow. Required transfers, reconciliation checks, and reporting data depended on disconnected or manual operational steps. Some records needed to move in one direction, while others needed to be compared; treating every requirement as the same synchronization task would have been incorrect.
CONSTRAINTS
System boundaries
- The existing systems and their operational responsibilities had to remain in place; the integration had to work across those boundaries rather than replace them with one shared data store.
- Financial records had to be validated before downstream use, with failed or incomplete processing made visible rather than silently accepted.
MY RESPONSIBILITY
Technical Consultant · Solution / Integration Architect
- Analyzed business and operational requirements, then mapped the participating systems, interfaces, data ownership, and required flow directions.
- Evaluated technical options and risks, defined the solution and integration architecture, and turned those decisions into an implementation plan.
- Developed the integration services and required processing, then owned testing, production readiness, technical and operational documentation, and delivery.

ENGINEERING CHALLENGES
Where the complexity lived
- Mapping different data representations and business rules, then deciding whether each flow required a directional update, a reconciliation comparison, or reporting data.
- Handling invalid input, incomplete processing, and failed runs without allowing an unresolved error to pass silently into a later financial operation.
APPROACH
How the solution was structured
- Specified each flow separately: its source and destination, required fields, execution condition, validation rules, expected result, and failure behavior.
- Implemented only the required direction for each transfer and kept synchronization, reconciliation, and reporting-related processing as distinct operations.
- Tested the defined flows and failure cases before production delivery, then documented system mappings, configuration responsibilities, and operational behavior.
OUTCOME
What the work established
- Delivered integration services, tested flow definitions, and supporting documentation that established repeatable paths for synchronization, reconciliation, and reporting data. For the covered workflows, this reduced reliance on manual transfer without treating every connected system as a bidirectional replica.
