Responsibilities
Conduct forensic-level analysis of the existing ACCIS legacy platform, including undocumented PowerBuilder code, embedded business rules, hard-coded eligibility thresholds, historical payment calculations, and exception handling logic accumulated over multiple decades
Reconstruct implicit system behavior by analyzing source code, database schemas, triggers, stored procedures, batch jobs, scheduler logic, and historical defect records
Produce exhaustive functional and technical documentation that captures both intended and emergent system behaviors, including edge cases that only manifest under rare policy, enrollment, or payment conditions
Serve simultaneously as Senior Business Analyst and hands-on technical contributor within the legacy and modernization environments
Independently create, modify, and debug SQL queries, and database objects as needed to confirm system behavior and support requirement validation
Participate directly in the troubleshooting of modernization components (e.g., .NET Core services, REST APIs, Angular components) to ensure exact functional parity with legacy logic
Translate business and regulatory requirements into both formal documentation and executable technical implementations
Develop highly granular business, functional, non-functional, and technical requirements that preserve legacy parity while enabling incremental modernization
Translate complex regulatory language, policy manuals, and operational practices into system-enforceable rules
Author requirements that explicitly map legacy ACCIS logic to future-state architectures, including one-to-one, one-to-many, and many-to-one functional transformations
Independently validate requirements against live production behavior to ensure no deviation from existing eligibility, enrollment, or payment outcomes
Simultaneously ensure strict regulatory compliance, audit readiness, and policy fidelity while meeting aggressive delivery timelines that may require expedited releases and limited regression windows
Balance competing directives to modernize functionality while maintaining absolute backward compatibility, even when such directives introduce technical or operational contradictions
Absorb and resolve conflicting guidance from policy authorities, auditors, business leadership, and technical teams without delaying delivery or increasing production risk
Design and maintain exhaustive test scenarios, test cases, and acceptance criteria derived directly from legacy system behavior
Coordinate parallel QA and UAT efforts across legacy and modernized platforms, ensuring identical outputs under identical inputs
Personally validate high-risk scenarios involving financial disbursements, retroactive adjustments, recoupments, provider rate changes, and eligibility recalculations
Ensure zero disruption to childcare subsidy payments, eligibility determinations, and compliance reporting throughout all releases
Analyze system data and operational outputs to identify inefficiencies, inconsistencies, and technical debt embedded in the legacy environment
Develop management-level reports that clearly articulate risks, dependencies, and downstream impacts of system changes
Recommend modernization approaches that balance technical feasibility, regulatory risk, budgetary constraints, and operational readiness
