GENEALOGY ARCHIVAL
SAAS PLATFORM
Multi-tenant genealogy platform combining interactive family trees, historical records, OCR data extraction, intelligent matching, and subscriptions.
Operational Friction
Family history researchers struggle with fragmented archives, incompatible record schemas, and manual transcription bottlenecks when organizing generational lineages.
Engineered Solution
Built a collaborative genealogy SaaS integrating automated historical record fetching, OCR document text extraction, and real-time family tree synchronization.
Architecture & Backend Implementation
Lead Backend Developer: Architected multi-tenant archival schemas, OCR extraction pipelines, and live collaborative graph traversal.
Designed recursive generational graph models and GEDCOM import/export data mapping.
Engineered document text extraction parsing historical certificates and census records.
Implemented Double Metaphone phonetic matching and Levenshtein distance algorithms.
Built Pusher-powered collaborative tree canvas with live node synchronization.
Key System Modules

Technical Deep-Dive & Decisions
Fuzzy Matching & Recursive Graph Traversal on Historical Records
Historical records frequently feature misspelled names, incomplete birth dates, and varying phonetics across decades. Querying deep generational graphs while correlating historical records posed severe performance challenges.
Systematic Resolution
Implemented Double Metaphone phonetic matching combined with Levenshtein distance scoring inside background queue workers, pre-computing record suggestions asynchronously.
Intentional Design Choice
Employed an adjacency list model with indexed path materialized views in MySQL to execute deep ancestor and descendant queries in single round trips.
Prioritization Rationale
Prioritized instantaneous tree rendering in the browser by offloading fuzzy record matching and archive discovery to background queues.
Expanded Application Views
Business & Operational Value
Transformed weeks of manual archive searching into automated background discoveries, connecting historical documents directly to family lineages.
Provided families with an intuitive, real-time collaborative workspace backed by rigorous tenant privacy controls.
