About Adam

-> Elite expertise (UK Ltd)

I am Adam, Founder and CTO of Perennix Ltd. I specialise in a critical field that many shy away from: the maintenance and modernisation of legacy applications (WinDev, legacy PHP, Ruby, COBOL, AS400).

My approach is pragmatic: we stabilise the existing systems (because they have to run!) and progressively modernise towards Cloud/SaaS/AI Integrations without breaking everything.

What I bring to you:

-> Legacy expertise: I am not afraid to get my hands dirty with proprietary or old code (PC Soft, COBOL, AS400, old PHP, system scripts). -> Modernisation Vision: I build the bridge between your technical debt and current standards (Docker, CI/CD, Azure, AI).
-> Delivery Capability (Nearshore): Through my company Perennix, I can steer your projects with fluid communication and competitive rates.

I have led critical projects for the banking sector (Natixis) and logistics (via nearshoring for a renowned French logistics provider). I understand the rigour required by sensitive production environments.

Let's discuss your current systems and how to future-proof them.
