Why hire me

Senior expertise. No agency overhead.

When you hire me, you get me — not a junior handed your project after the sales call. Two decades modernising how EPCM organisations design, build, and deliver — applied directly to your transition from legacy to digital.

🎯

Direct senior involvement

Every engagement gets my full attention. No account managers, no handoffs, no surprises.

⚙️

BIM engineering, not just administration

Most consultants configure CDEs. I build what sits underneath — IFC pipelines, digital twins, WBS-to-BIM trackers, and ACC API integrations written from scratch.

🌍

Built for African complexity

Low-bandwidth environments, multi-jurisdiction compliance, cross-border teams — I've solved these in production, not on a whiteboard.

📈

Measurable outcomes, always

Every engagement targets concrete business results: faster retrieval, lower latency, zero-downtime migration. Not lines of code shipped.

Core Expertise

Two decades of depth across the full engineering stack.

Not a generalist. A specialist with documented results in each of these disciplines.

🏗️

BIM & IFC Engineering

Engineering at the BIM layer — IFC development and parsing, WBS trackers linked directly to IFC elements for live project visibility, digital twin environments, and full CDE administration across ProjectWise, ACC, and Aconex.

💻

.NET / C# Development

Full-stack enterprise development: Clean Architecture, Domain-Driven Design, microservices, REST APIs. Production-grade code that survives handover.

.NET Core C# SQL Server Entity Framework

☁️

Azure DevOps & CI/CD

Automated deployment pipelines, Infrastructure as Code, enterprise-grade cloud security, and release management that eliminates manual errors.

🖥️

Full-Stack Web Development

Modern frontends that work — React, TypeScript, HTML/CSS/JavaScript. Built for real users with real constraints, not just demos.

Integration Engineering

Bridging legacy environments with modern platforms — ERP integrations, API gateways, and data pipelines that keep multi-site operations connected during and after the transition.

REST APIs SharePoint ERP Power Platform

🧭

Technical Leadership

Architecture reviews, code standards, and mentoring. I can lead your team through a digital transformation, or audit what's already been built.

🤖

AI-Assisted Development

Proficient with Claude and the broader AI development toolchain — prompt engineering, agentic workflows, and integrating LLMs into production .NET and cloud platforms. Applying AI tooling to accelerate delivery without sacrificing code quality or maintainability.

EPCM / Digital Twin

Multi-year engagement

IFC-Based Digital Twin & EPCM Deliverables Platform

Designed and built a suite of interconnected platforms for a major EPCM programme: an IFC development pipeline linking live project elements to a WBS tracker, a digital twin environment reflecting real-time construction status, and a transmittal and deliverables platform replacing manual EPCM documentation workflows. All integrated with Autodesk Construction Cloud via API.

Real-time WBS tracking linked directly to IFC model elements
