about.md

I'm a Senior Full Stack Architect with 14+ years delivering enterprise SaaS platforms on .NET, React, and Azure. I've proven myself as an external contract resource on multi-year engagements for global clients including S&P Global and ProcessUnity — designing scalable cloud-native architectures, modernising legacy systems, and leading engineering teams.

I care deeply about clean architecture, meaningful abstractions, and working closely with teams to turn complex requirements into elegant, scalable solutions.

I use Claude Code and agentic AI workflows to compress development and review cycles — delivering senior-architect quality at a competitive rate. Available for remote contract engagements with international clients.

Client: ProcessUnity · Lead Architect

Lead architect in a 6-engineer team delivering ProcessUnity's third-party risk platform — trusted by 600+ enterprise clients managing an ecosystem of 600,000+ vendors. Rebuilt the notification email system with a configurable MUI-Tiptap rich-text editor wired to the in-house Expression engine, turning static alerts into dynamic, data-driven communications. Cut notification image-load time ~30% by re-encoding inline images to WebP before base64 storage, shrinking embedded payloads 35–40% with no visible quality loss.
