Enterprise Migration

Legacy Middleware Modernization

Moved a legacy integration platform onto modern middleware without breaking anything downstream.

Lead Integration Engineer IBM ACE · ESQL · SOAP/REST
  • Rebuilt several core services as modular ACE message flows instead of just patching the old ones.
  • Added schema validation and ran the old and new systems side by side to catch mismatches before switching over.
  • Retired the legacy platform once everything downstream kept working without changes.
Regulatory & Compliance

Automated Compliance Screening Integration

Built an automated screening pipeline so compliance checks didn't have to be done by hand.

Integration Developer IBM ACE · API Connect · SQL · Security
  • Connected portal submissions straight to the backend vetting system instead of a manual handoff.
  • Set up authenticated REST endpoints with logging so every check leaves an audit trail.
  • Pulled data in from a few different sources automatically, which cut review time down a lot.
Financial Data

High-Volume Financial Data Ingestion

Built a pipeline to ingest and validate large volumes of financial records without falling behind.

Middleware Developer IBM MQ · ACE · SQL Database · Batch Engine
  • Set up queue clustering to move encrypted batch transfers reliably.
  • Wrote multi-threaded parsing flows so large record volumes still finished inside the SLA window.
  • Added dead-letter handling and reconciliation so nothing got silently dropped.
Secure Integration

Secure Cross-Organization Data Integration

Built secure channels for exchanging data between organizations in real time.

Integration Specialist IBM ACE · mTLS · XML/JSON
  • Helped set up mutual-TLS and signature verification so both sides could trust the connection.
  • Built message flows that worked both synchronously and asynchronously depending on what was needed.
  • Made sure the encryption and non-repudiation requirements were actually met, not just written down.
AML / Screening

Automated AML & Risk Screening Integration

Built a tool to automate Anti-Money Laundering (AML) and risk screening checks.

Integration Developer REST API · Python · SQL
  • Connected to a third-party screening API using custom HMAC-SHA256 authentication.
  • Wrote name-matching and risk-scoring logic to flag entities that needed a closer look.
  • Added audit-trail reporting so past decisions stayed on record.
