I've been building for the web since the late 90s - from KPMG back-office systems and the NY Daily News CMS to out-of-home media platforms at OUTFRONT Media, used by millions of commuters. Today I run The DJ Calendar, an electronic music event discovery platform I founded in 2015: ~1,000 schema.org-rich pages, a custom PHP/MySQL stack, newsletter infrastructure, and zero-dependency tooling I build when the off-the-shelf answers aren't good enough.

I like my software the way I like my sets: no bloat, every element intentional.

A series of small, production-derived repos - each one isolates a single engineering problem from The DJ Calendar and publishes the pattern, not the infrastructure:

• dj-card-preview (https://github.com/bryanhamiltondev/dj-card-preview) - The homepage hover-preview card: a 30-second iTunes audio preview, an 8-bar EQ driven by the real audio frequencies via Web Audio, and a consent-first contract for touch, reduced motion, and conflicts. Live demo included.
• instant-search-index (https://github.com/bryanhamiltondev/instant-search-index) - Instant client-side search from a prebuilt JSON index: scored matching (AND semantics, weighted fields, phrase bonus), a fully ARIA-wired combobox, and keyboard-first navigation. Runs site search across ~1,000 pages with no search server and no library - one file, zero round-trips.
• tour-feed-pipeline (https://github.com/bryanhamiltondev/tour-feed-pipeline) - Bandsintown + Ticketmaster feeds normalized into one row shape, deduped across sources, cached with versioned JSON files, pruned for freshness. CI-tested on PHP 8.1/8.3.
• jsonld-schema-audit (https://github.com/bryanhamiltondev/jsonld-schema-audit) - Zero-dependency PHP CLI that audits JSON-LD structured data: validates required properties per schema.org type, resolves every internal @id reference, and fails CI on regressions. Took The DJ Calendar from hundreds of Rich Results warnings to zero.
• csrf-json-fetch (https://github.com/bryanhamiltondev/csrf-json-fetch) - Hardened vanilla-JS fetch wrapper: CSRF token lifecycle, header+body dual injection, and a strict single-retry-on-expiry policy.
• sri-lazy-loader (https://github.com/bryanhamiltondev/sri-lazy-loader) - Race-safe lazy script loader with Subresource Integrity: concurrent-caller dedupe, pre-existing-tag detection, timeout with cleanup.
• event-calendar-schema (https://github.com/bryanhamiltondev/event-calendar-schema) - MySQL schema and PDO data layer: idempotent event upserts, double opt-in subscribers, query-shaped composite indexes.
• wp-schema-audit (https://github.com/bryanhamiltondev/wp-schema-audit) - WordPress plugin port of the schema auditor: WP-CLI command, admin Tools page, and a CI self-test that asserts both the pass and fail directions against real fixtures.
• next-show-radar (https://github.com/bryanhamiltondev/next-show-radar) - The geolocation-aware tour map from the platform: consent-first geolocation with a documented deny contract (global view + announced fallback), haversine radius fitting, and race-safe Leaflet boot. Pairs with sri-lazy-loader, which brings the map engine in safely.
• eq-visualizer (https://github.com/bryanhamiltondev/eq-visualizer) - The 8-bar sensory equalizer from the homepage cards, extracted as a zero-dependency widget: pure CSS animation, an optional 1 KB injector, and reduced-motion respect built in.
• The DJ Calendar - electronic music event discovery: Leaflet-based city maps, newsletter infra, and a homegrown SEO/schema pipeline.
