Production Systems
Detailed engineering breakdowns of mission-critical systems. Each case study documents the real-world problem, architectural decisions, trade-offs, and verified production metrics.
Problem: Headless CMS outages risk storefront downtime, while custom database stores lack visual rich-content editors for marketing teams.
Architecture: Architected a bidirectional dual-sync pipeline across Next.js, Sanity CMS, and a zero-latency database failover with DNS email forwarding.
Impact: Achieved 100% storefront uptime through automated database failover with zero-cost custom domain email routing to Gmail.
Problem: Healthcare networks required FDA-approved zero-latency diagnostic medical viewing and bidirectional bridges between legacy HL7 and modern FHIR.
Architecture: Architected FDA-approved C#/VC++ 2D/3D diagnostic viewing software with hospital PACS networking and HL7-to-FHIR transformation bridges.
Impact: Delivered certified FDA-approved diagnostic viewing across desktop and web with reliable clinical PACS transmission.
Problem: Manual candidate resume screening created heavy recruitment backlogs and subjective, inconsistent technical evaluations.
Architecture: Engineered an automated n8n pipeline combining Gemini Flash semantic scoring, Outlook monitoring, and LlamaParse CV attachment extraction.
Impact: Automated mailbox candidate triage end-to-end, slashing candidate screening turnaround by over 80%.
Problem: Substation device configuration required strict compliance with complex IEC61850 international standards and multi-vendor protocols.
Architecture: Engineered an extensible plug-in architecture with a responsive C#/WPF UI, decoupled business logic, and MongoDB document persistence.
Impact: Standardized configuration workflows under IEC61850 with zero-friction hardware extensibility and high-throughput data access.
Problem: Electrical grid engineers required real-time analysis of immense historical phasor and SCADA datasets without UI thread lockup.
Architecture: Architected high-performance WPF MVVM desktop UI and migrated core capabilities to containerized cloud microservices via Helm charts.
Impact: Delivered real-time phasor visualization with +30% deployment agility and client on-site invitation (USA) for UX excellence.
