Engineering Capabilities

PHP Development, AI Engineering, SEO, and Infrastructure Services

Four disciplines. All in production — each one shipped and operated continuously, not a capability added to a menu.

01 / Software Engineering

Software & SaaS

Operational software where data integrity, uptime, and financial accuracy matter. Custom web applications on typed PHP 8.5 with strict MariaDB schemas. Multi-tenant SaaS platforms with subscription billing and automated invoicing. REST APIs with consistent, documented responses. Android apps that work offline. Every component is zero-framework — no hidden abstractions between your business logic and the database.

02 / AI Engineering

AI & Intelligent Systems

The difference between an AI demo and an AI system is what happens when the model returns something unexpected. Autonomous agents with deterministic tool-calling and explicit failure modes. Vector retrieval that returns relevant results because the embedding strategy matches the query pattern. Multi-step workflows that execute without human intervention and report clearly when they can’t.

03 / Search Engineering

Technical SEO & AI Search Visibility

Search visibility is an engineering problem. Crawl architectures that search engines can traverse, Schema.org entity graphs that make content machine-readable, and structured data strategies that surface your site in Google AI Overviews, ChatGPT, and Perplexity.

04 / Infrastructure

Infrastructure & Operations

DMARC/DKIM/SPF email authentication that passes every compliance check. Hardened hosting with automated rollback. DNS topology that survives provider outages. Infrastructure management for production systems where uptime is not optional.
