A CRM for a property and investment business: public enquiries triaged into contacts, opportunities tracked through their own approved stage sequence for each of four investment routes, and every read and write decided by the database.

Architecture, from the case study A case-management platform for a regulated advisory practice: stages, statutory deadlines, tasks, document control and an internal fee ledger.
The operating system for my own software company: public website and internal CRM in one application, from lead through proposal, project, invoice and payment.
AI editorial tooling inside a news publishing platform: the model drafts the excerpt, SEO title and meta description, the editor approves or rewrites them, and the generation endpoint is guarded so it cannot become someone else’s API bill.
Architecture, from the case study A scheduling workflow that turns meeting instructions sent in a team chat into Google Calendar events, with the trigger narrowed and the date handling pinned so that the automation acts only on the messages it should.

Where the manual steps go
Most operational work leaks through the gaps between systems — a message read late, a date typed into the wrong day. Automation closes the gaps; AI is one node inside it, not the point of it.

- Calendarautomatic
- Notificationautomatic
One system, one bounded decision. The AI step is the only one allowed to interpret anything — everything around it is deterministic.

Work with me directly
I design and build the technology a business runs on, and stay responsible for it end to end: data model, backend, interface, deployment and the changes afterwards. On most of the projects in my portfolio I am the only developer.
Or with the studio
One technology partner. From software and automation to digital growth.
Through AM IT Solution, I'm building a digital solutions agency that brings software engineering, intelligent automation and digital growth services together under one roof. Larger engagements are delivered through the company.

Multi-tenant scoping in PostgreSQL that survives a rewrite
Every tenant table carries the organisation, every query goes through one layer that puts it there, and a build-time check fails the build if application code ever reaches the database directly. The discipline is the design.

How I structure role-based access in business applications
Hiding a button is not security. A permission model that survives contact with a real business needs one catalogue, enforcement in the service layer, and a short list of actions that only two people may ever perform.
Have a workflow your team keeps doing manually?
Let us work out whether it needs better software, automation, or both. Tell me how the process runs today and I will tell you which of the three it is.
