View ResumeAbout
As a seasoned full-stack architect specializing in domain-specific platform development, I design and implement complex, multi-tenant systems that solve real industry problems. My background combines enterprise experience (Form Health, Dassault Systèmes, Bose, Cengage) with interdisciplinary education—BS in Business Administration (International Business, Finance) and MLA in Digital Media Design from Harvard Extension School.
Currently, I'm architecting Knokr—a platform ecosystem addressing data fragmentation in the music industry. The system demonstrates sophisticated application architecture: a shared PostgreSQL infrastructure with pgvector extensions powering four interconnected applications (Base, Orchestra, Lineups, Nuncio). Each serves distinct purposes while feeding a unified data model, enabling rapid experimentation in isolated environments before integrating proven features into the core platform.
Key technical implementations include a Database-Driven Routing Engine where URLs are defined in the database rather than file paths, enabling non-technical users to create pages without deployments. AI Integration at Scale using Claude API for festival lineup extraction from posters, processing hundreds of artists per festival in near real-time. Vector Search and Graph Intelligence built with OpenAI embeddings, pgvector, Node2Vec algorithms, and Louvain scene detection. Performance Architecture achieving 90-95% latency reduction through Redis caching strategies, with comprehensive testing (2,300+ tests with Vitest, Playwright, Testcontainers).
I excel at iterative architecture development—building experimental platforms that share infrastructure with production systems, validating features before integration. This methodology reduces risk while maintaining velocity. Whether architecting multi-tenant systems with strict data isolation, implementing AI-powered extraction pipelines, or designing graph-based discovery algorithms, I focus on platforms that scale technically while solving meaningful domain problems.

Knokr
A festival discovery and social platform that consolidates lineup data, schedules, and artist information across 1,400+ festivals and 50,000+ artists into a single searchable interface — replacing the fragmented experience of browsing dozens of individual festival websites. Features AI-powered lineup extraction from festival posters using Claude Vision API, semantic search with pgvector embeddings, a dream lineup builder with drag-and-drop organization, and a conversational recommendation engine for personalized festival comparisons. Beyond discovery, the platform connects festival attendees with each other, enabling social coordination around shared lineups and events. Evolved from an earlier Python-based extraction tool through multiple architectural iterations, with features validated through standalone experimental platforms before integration.

Knokr Base
The administrative backbone of the Knokr ecosystem — a multi-tenant back office managing the full lifecycle of data across 50,000+ artists and 1,400+ festivals. Handles image uploading and processing, festival metadata, lineup and schedule management, and artist profiles including show and festival histories. Implements comparison models for surfacing similar artists and festivals using graph-based relationships and vector similarity. Features database-driven routing that lets pages be created from the database rather than the filesystem, a five-tier permission system for multi-tenant access control, and vector search powered by OpenAI embeddings. Shares a PostgreSQL infrastructure with Knokr, enabling both applications to operate against a unified data model while serving distinct audiences — public discovery and internal data management.

Demo — awaiting final content and visual design
A turnkey festival website exploring PayloadCMS as a white-label foundation for festival organizers. Built for a client's one-day festival, the project started from Payload's stock website template (blog + 4 basic blocks) and required substantial rework — 24 custom block components, a complete S3 media system replacing Payload's broken upload pipeline, live database integration pulling lineup, schedule, and venue data from Knokr's shared PostgreSQL infrastructure, interactive Leaflet venue maps, and a brand-specific design system. The experiment validated both the value of the Knokr data layer for powering external sites and the limitations of adapting a generic CMS for domain-specific use cases — informing the architecture for purpose-built festival site tooling. 232 TypeScript files, multi-database architecture, deployed to Railway.

Knokr Predictor
Ongoing development
A festival lineup prediction system that generates probable artist bookings for upcoming festival editions using Knokr's music discovery graph. Queries 3.3M pre-computed artist co-occurrence edges weighted across eight signal types (shared festivals, shared venues, band members, local/national scene overlap), combined with Louvain community detection scoring and genre-depth multipliers to rank candidates against a festival's existing lineup profile. Features automatic similar festival discovery, weighted random sampling with square-root flattening for variety, confidence tiering, and per-artist contributing factor breakdowns. Python prediction engine (FastAPI, asyncpg) communicating with a Next.js frontend via Redis queue, both reading from the shared Knokr PostgreSQL database. Deployed to Railway.

Orchestra
Live — no longer under active development
A focused experiment in mapping artist relationships within the music industry. Enables users to search across 50,000+ artists and contribute band member connections through a curated submission process, building primary, secondary, and tertiary relationship networks. Built as a standalone platform to rapidly test community-driven data contribution workflows and graph-based artist discovery — learnings that directly informed the comparison models and artist relationship features in Knokr Base.

An open event curation platform built to test AI-powered data extraction and public content distribution at speed. Users create and share unlimited event lists with AI-assisted tour date extraction from images, embeddable widgets, and export formats including JSON-LD, iCal, and RSS feeds. Served as a proving ground for the image extraction pipeline and structured data patterns later adopted in Knokr's lineup extraction system.

Knokr — Earlier Iterations
No longer under active development
The original Knokr platform: a frontend for social music discovery, a back office supporting festival scheduling from single-day showcases to multi-day, multi-city, multi-stage events with 100+ artists, and KnokrFetch — a Python-based scraping system that pulled event data from Bandsintown, Songkick, and Seated alongside custom parsers for Wix, WordPress, Squarespace, and bespoke sites. These earlier builds established the domain model, data acquisition patterns, and scheduling complexity that the current Knokr and Knokr Base architecture is built on.
