Open source packages
for PHP teams.
Queue autoscaling, system metrics, PHP-FPM monitoring, health checks, and more. Built because I needed them, maintained because others do too.

A zero-runtime-dependency DNS toolkit for PHP. Speaks the wire protocol over raw sockets to read answers straight from a zone authoritative nameservers, plus domain verification, DNSSEC validation and intoDNS-style diagnostics.
Prometheus exporter for PHP-FPM. Collects metrics from FPM pools, opcache, and Laravel queues via FastCGI. Multi-site support.
PID 1 process manager for Docker containers. Handles signal forwarding, zombie reaping, PHP-FPM auto-tuning, health checks, and Prometheus metrics.
A gateway-agnostic billing engine for Laravel: catalog, subscriptions, real-time usage metering with hard limits, a double-entry ledger, wallets and credits, invoicing and pricing. The framework peer to laravel-id.
The DNS toolkit for Laravel: authoritative lookups, domain-ownership verification, DNSSEC validation and intoDNS-style diagnostics, exposed through a facade, Artisan commands and validation rules.
A Laravel-native auth and identity framework you bind into your own app. Central login, enterprise SSO (SAML/OIDC), SCIM directory sync, RBAC, billing-fed entitlements and a tamper-evident audit trail, all interface-driven and deny-by-default.

How Hard Can US Sales Tax Be
I was building a billing engine, so I had to handle tax. The EU was hard but knowable. Then I looked at the US and said the sentence that sits right at the peak of the Dunning-Kruger curve. What came out the other side was not tax logic, it was an ETL pipeline against forty government websites.
One Identity Layer Instead of Five
Every product needs login, organizations, roles, SSO and an audit trail. I had built that more than once, a little differently each time. Identity is the last thing you want five diverging copies of, so it became laravel-id: a contract-driven auth and identity framework for Laravel.
The Code We Kept Rewriting
SSRF guards, risk scoring, jurisdiction lookups, DNS reads. The same logic was already in production across several projects, written fresh each time and tuned to each one. Maintaining five copies stopped making sense, so I pulled each into a single open source package.
Let's build something
that lasts.
