Paul Mercieca
Chief Technology Officer
Based in United Kingdom
Summary
I am a CTO, AI Strategist and Senior Engineer with over 13 years of experience building and scaling robust B2B platforms.
About
I specialize in partnering with companies across the iGaming, construction, and retail sectors to architect custom SaaS solutions, modernize legacy infrastructure, and securely integrate AI into daily operations.
Having previously served as Head of Engineering in the high-stakes, highly regulated online gaming industry, I understand how to balance aggressive commercial goals with scalable technical execution. Today, as an independent technical partner, I bridge the gap between business strategy and hands-on engineering, delivering high-velocity MVPs and enterprise-grade architecture without the overhead of a full-time executive hire.
My architectural experience spans complex API middleware, high-transaction reconciliation engines, and bespoke internal tooling designed to eliminate operational friction. Whether I am scoping out construction management platforms, designing restaurant and retail operational workflows, or building out custom Remote Gaming Servers, my focus is always on creating systems that directly impact the bottom line.
A core pillar of my consultancy is practical AI automation. I focus on deploying enterprise-grade, human-in-the-loop AI workflows that drive efficiency while maintaining strict security, architectural integrity, and operational control.
Core Services & Expertise:
- Fractional Technical Leadership: Architecture audits, engineering velocity, technical debt reduction, and cross-functional team alignment.
- AI & Workflow Automation: Secure LLM integration, custom AI agents, and strict human-in-the-loop security controls.
- Custom Software Engineering: End-to-end full-stack development, bespoke SaaS, and legacy system modernization.
- Domain Specialization: High-transaction iGaming platforms, construction tech (PropTech), and retail operational software.

Engagements commonly include technical due diligence, board reporting, engineering team leadership, technology strategy, architecture reviews, hiring support, and stepping in as interim CTO during a transition.
