Selected Engineering Experience

Strengthening application security across distributed legacy platforms and high-velocity engineering teams.

Conducted comprehensive threat modeling, established zero-trust architectural boundaries, and integrated automated security scanning into CI/CD pipelines. (OAuth2/OIDC centralized identity, API Gateways, container security, and infrastructure as code.)

Eliminated critical vulnerability backlogs and instituted verifiable security guardrails without degrading release velocity.

Architecting a reliable data pipeline to ingest, validate, and report critical financial compliance data under strict deadlines.

Engineered an event-driven integration architecture separating ingestion, validation rules engines, and auditable reporting layers. (.NET Core microservices, Azure Service Bus, SQL Server temporal tables, and automated reconciliations.)

Achieved 100% regulatory audit compliance with deterministic data verification and zero manual intervention.

Overcoming hallucination and security risks while enabling thousands of staff to query complex technical documentation and policy files.

Built a private, domain-bounded Retrieval-Augmented Generation (RAG) system with strict role-based access controls and deterministic source citations. (Vector embeddings, hybrid lexical/semantic search, local and cloud LLM routing, and strict audit logging.)

Reduced query resolution time from hours to seconds while maintaining full data isolation and governance.

Unifying fragmented inventory, financial, and operational software across disparate business units.

Designed a unified service layer and domain model to synchronize disparate legacy data sources in real-time. (C#/.NET backends, RESTful APIs, transactional message queues, and resilient retry patterns.)

Eliminated manual cross-system data entry errors and provided leadership with single-pane-of-glass operational visibility.
