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.
Products
Cbox ID, Telemetry, Billing, Cortex, Status and Assistant. Run them yourself where they are open source, or let us host them.

Has been writing code and running servers since 2000. Built the CMS and Kubernetes infrastructure behind TV2's regional news sites, co-founded a drone inspection startup used by national railway operators, and now makes open source packages for PHP teams. These tools exist because I needed them.

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.
PID 1 process manager for Docker containers. Handles signal forwarding, zombie reaping, PHP-FPM auto-tuning, health checks, and Prometheus metrics.
Durable, multi-step operations for Laravel. Track a deploy, a provisioning run or an import as a first-class record with a strict state machine, per-step progress, idempotent retries and a stall sweep, instead of a black-box job.
Postal mail server integration for Laravel: a typed multi-server send transport, verified webhooks for delivery, bounce, open, click and DNS events, inbound email and an idempotent per-message status store.
Queue monitoring and metrics for Laravel. Job execution times, success rates, failure patterns, worker health, and Prometheus export.
Queue visibility without Horizon or Redis. Track every job on any driver with per-job CPU, memory, retry chains, replay, and a terminal dashboard.

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.
Why I Built a Collector-Free Telemetry Package for Laravel
Sentry and Nightwatch showed green while customers saw errors. Nothing ever threw, and sampling dropped exactly the requests that mattered. That incident, collector fatigue on Kubernetes, and a family of packages that all needed metrics became "Telemetry for Laravel".
Let's build something
that lasts.
