In-depth technical overviews

Areas of expertise

Detailed technical overviews of the platforms, architectures, and verticals we work in. Each page covers the real stack — not a brochure description but how the infrastructure is actually built, tuned, and operated in production.


Technical overviews

Platform

FreeBSD production infrastructure

Multi-server FreeBSD environments with iocage jails, ZFS, bhyve, pf, Puppet/Hiera, HAProxy, BIND, MariaDB, nginx, and PHP-FPM. The architecture, the tooling, and the diagnostic capability — DTrace and ktrace — that make FreeBSD the right platform for production infrastructure that needs to stay up and be understood when something goes wrong.

Architecture

High availability infrastructure

Dual HAProxy with CARP on bare metal or heartbeat elastic IP failover on AWS. Scalable PHP-FPM pools across redundant hosts. MariaDB primary/replica with zero-downtime promotion. And a Nomad/Consul/pot orchestration stack with dynamic HAProxy node insertion for workloads that need to scale automatically — built and operated on FreeBSD.

Operations

Monitoring & observability

A three-layer mesh: monit for local service recovery with Pushover/Prowl push alerts, collectd feeding Graphite and Grafana for metrics and trending, and multi-geo external validation from Miami, Washington DC, and London with content validation — not just status codes. Custom instrumentation for signals that matter: queue latency, PHP-FPM busyness, Valkey fragmentation, third-party API health, and 1000+ domain certificate and expiry monitoring.

Platform

Linux consulting & Docker

Senior Linux administration for Ubuntu and Debian environments, fleet standardization including two large-scale migrations to FreeBSD, Docker and Podman deployment with Alpine Linux base images, and application integration work — Airbyte, KasmWeb, Pinba, headless Chrome for Puppeteer, and custom stacks. Cross-platform depth from 20 years of FreeBSD applied to Linux environments.

Vertical

PPC & affiliate marketing infrastructure

Infrastructure engineering for performance marketing platforms — PPC, affiliate marketing, price comparison, and lead generation. Redis cluster hourly traffic monitoring, bid management systems, RPC tracking, ETL pipelines to BigQuery, SMS and email delivery with latency circuit breakers, and blended feed management for Google AFS, Yahoo!, Taboola and others. Experience operating platforms generating $30M+ annual revenue.

Case studies

Real problems from production environments — the diagnostic process, the tools, the root cause, and what changed.

Diagnosis GeoIP segfault — the blank page Pingdom never saw Legacy rescue PHP 5 application on failing hardware — iocage jail migration Database engineering Zero-downtime MariaDB migration — tarpipe replication seeding Kernel diagnosis ZFS ARC eviction — Valkey jemalloc fragmentation Diagnosis PHP-FPM deadlock — health checks passing, workers blocked Diagnosis Geographic API latency — TCP stack was idle, application was blocking Database & storage InnoDB stall — ZFS sync write amplification and SLOG Kernel diagnosis Scheduler latency — 100 threads competing for 16 cores
