I mostly build custom RAG systems and AI workflow automation for startups and small teams. I also build websites and native iOS and macOS apps. You work with me directly, the scope is agreed in writing before work starts, and you see a working demo early. I build the app and the infrastructure it runs on.
AI systems
RAG systems that answer from your own documents, automations that take repetitive work off your team, and chatbots for your website.
Custom RAG Development

Security patching for the servers your sites and apps run on, including old PHP versions that no longer get official fixes.
PHP Security Patching
$100 – $1,200one-time, based on scope
Your servers patched against critical PHP vulnerabilities such as CVE-2026-109618 and CVE-2026-109619. Supported versions get the official update. Old PHP versions get the fix backported and compiled into a patched build, and your own code is fixed where it's exposed too.
An audit of every PHP version, SAPI and server you run
Updates to the fixed official release where your PHP version is still supported
Patched builds for old PHP versions (7.4, 8.0, 8.1, and older ported by hand)
Fixes in your own code where a vulnerability can reach it
Before-and-after testing, a rollback plan and a written report
Running costs and what's not included
You pay providers directly
Server, hosting and any control panel licences
Paid extended-support PHP builds, if you choose one instead of a backport
Not included
Shared hosting where you have no root access (your host has to patch PHP)
A full penetration test, incident response or malware clean-up, quoted separately
Upgrading your application to a newer PHP version, quoted separately
After launch
Bug fixes for 14 days. After that, changes are quoted, or you can hire me monthly.
Prices are starting points. The final quote depends on what your project needs, and you'll get it in writing before any work begins, with running costs and the support window spelled out. Working on something bigger, like a full SaaS platform or a custom AI model? Let's talk about it.
