Digital Systems Architect · Technical Founder
Building, shipping and operating real systems

I turn ambitious ideas into working digital businesses.

I am a Digital Systems Architect and Technical Founder who works across AI, SaaS, automation, infrastructure and full-stack product engineering. I take projects from rough commercial idea to architecture, production deployment and the operational reality that follows.

The difference

I operate in the space between strategy and the terminal.

Most people specialise in either the business conversation or the technical implementation. My value is being able to move between both, without dropping the thread.

“I do not just build features. I build the system around the feature, the path to production, and the business logic that makes it worth having.”

My background spans engineering operations, sales, product ownership, software architecture and production infrastructure. That mix makes me unusually comfortable with messy real-world requirements, commercial pressure, legacy systems and the unglamorous work required to make technology dependable.

Build from zeroI am comfortable starting with a blank repo, a rough idea and a commercial constraint.
Own production realityServers, DNS, SSL, backups, queues, cron, workers, deployments and recovery are part of the job.
Think like an ownerI care about cost, rollout, margin, licensing, support load and what happens after launch.
Selected systems

Products and platforms with actual operational weight.

A selection of founder-led and client-facing systems spanning SaaS, utilities, AI, automation, travel, infrastructure and operational software.

Utility technology · Multi-tenant platform

MY.POWER

Smart utility management architecture covering landlords, tenants, partners and internal administration, with metering, tariffs, billing logic, reporting and operational controls. Current work extends the platform toward AI-assisted customer operations and scalable smart-metering deployment.

Domain complexityMetering, billing, allocation, permissions and stakeholder separation.
Platform directionFrom billing software toward an integrated utility operating platform.

Voice AI · Productised automation

AI Front Desk

Production-oriented AI receptionist architecture combining real-time voice, telephony, business workflows, client-specific personas and modular deployment. Designed as a repeatable product rather than a one-off chatbot.

Realtime stackVoice agents, SIP/telephony, LiveKit-style room and routing patterns.
Deployment modelPer-client product instances with governed configuration and lifecycle control.
Voice AISIPLiveKitLLMsGPU inferenceWhatsApp
Local AI · Autonomous engineering

WiLL Core & WiLL Coder

Private AI engineering and automation tooling built around local language models, tool execution, persistent context, remote GPU compute and verification-first workflows. Includes dynamic compute provisioning and modular autonomous add-ons.

AI infrastructureLocal inference, remote GPU capacity and model-serving workflows.
Agent engineeringTool governance, context, memory, verification and autonomous execution.

Travel commerce · Booking operations

Travel Curator ZA

Built and deployed a production travel platform combining content, trip management, departures, bookings, deposits, instalments, payment notifications, secure customer access and operational administration.

CommerceDeposits, instalments and payment-provider workflows.
ProductionDedicated VPS stack, database, backups and deployment ownership.

Operational software · Business systems

Multi-industry platforms

Built and shaped systems for steel, project management, waste, health and safety, property, mobility, commerce and internal operations. The common thread is practical workflow design: turning real processes into controlled, auditable software.

Capability stack

I work across the whole system, not just one layer.

That breadth is deliberate. It lets me make architecture decisions with awareness of product, infrastructure, users, operations and commercial reality.

01

Systems & platform architecture

Domain modelling, modular architecture, access lanes, data flows, roles, lifecycle states, platform boundaries and pragmatic technical strategy.

02

AI & agent engineering

Voice agents, local LLMs, tool-driven assistants, context and memory patterns, model infrastructure, safety gates and autonomous workflows.

03

Full-stack engineering

Backend-first product delivery with PHP, Python, SQL, JavaScript, admin tooling, dashboards, APIs, integrations and production-safe interfaces.

04

Infrastructure & operations

Linux, VPS environments, Apache/Nginx, DNS, SSL, cron, queues, backups, deployment isolation, incident diagnosis and recovery.

05

Automation & integration

API orchestration, webhooks, workers, scheduled processes, payment integrations, notifications, telephony and operational system glue.

06

Commercial product thinking

Pricing logic, white-label models, rollout strategy, recurring revenue, partner channels, implementation cost and support-aware product design.

Working stack

Technology I use to get the job done.

Tools change. The engineering judgement behind choosing and operating them matters more.

Career path

Commercial operator turned systems builder.

My route into technology came through real operating businesses. That history still shapes how I build: systems must make sense to the people paying for them and the people using them.

2007–2017

Engineering & commercial operations

Sales, marketing, project management, workshop leadership and business ownership across steel and engineering.

2017–2019

SteelTradersAPP

Founder of an online marketplace concept connecting buyers and sellers through pricing and availability workflows.

2019–2023

MyTown Apps

Delivered websites, platforms and internal tools, owning scope, development, deployment and support.

2019–Now

MY.TOWN ecosystem

Architecture and product leadership across SaaS, utilities, AI, automation, infrastructure and commercial digital systems.

Where I fit best

Give me ownership, complexity and a real outcome.

Strong-fit roles

Digital Systems / Solutions ArchitectWhen architecture must stay connected to delivery and operations.
Founding or Principal EngineerWhen one person needs to turn uncertainty into a working platform.
AI Systems & Automation LeadFor practical agent, voice, local-model and workflow implementations.
Technical Product Lead / Fractional CTOWhere commercial direction and engineering decisions must meet.

Strong-fit environments

Founder-led product companiesFast-moving teams that value judgement, ownership and useful output.
Complex operational businessesUtilities, services, travel, property, commerce and admin-heavy workflows.
Platform rescue and modernizationSystems that work, but need structure, hardening, clarity and momentum.
AI productisationMoving AI from impressive demo to governed, repeatable business product.
Let’s build something useful

If the problem is difficult, that is usually the interesting part.

Open to the right remote, contract, architecture, technical leadership and founder-grade build opportunities. Email and phone reveal on interaction to cut down scraping. Honest humans get through. Bots can go cry in a log file.
