What I'm looking for

I am looking for senior-level roles where I can architect backend systems, lead integrations, modernise legacy platforms, and work collaboratively with stakeholders to deliver measurable business value.

I am a Senior Backend Engineer and Solutions Consultant with 10+ years building bespoke technical solutions across Logistics, Construction, Healthcare and Field Services. I combine deep PHP/Symfony expertise with a consulting mindset to translate operational problems into reliable, production-grade systems.

My achievements include leading complex system integrations, architecting business-logic monitoring, rescuing stalled critical projects as an on-site technical lead, and modernising legacy codebases with testing and static analysis. I focus on database optimisation, performance tuning and designing internal tooling that reduces developer overhead.

I work effectively in remote and asynchronous teams, emphasise clear stakeholder communication, and deliver tangible business outcomes through pragmatic architecture, CI/CD practices and rigorous testing.
