Enterprise Systems
18+ years turning slow, costly legacy systems into fast, reliable ones. I measure success in hours saved, costs cut and happier customers, not lines of code.
01 / about
A developer who has sat with the customer when things broke.
I moved from development into professional services and third-line support, working on-site with global customers and handling critical enterprise escalations, before returning to code. I took customer satisfaction from 85% to 98.9% along the way.
That shapes how I build now: I start from the business problem, talk to the people who feel it, and ship software that the business can measure and the support team can live with.
outcome_firstStart from the business problem and the number that proves it is solved: cost, time, or customer satisfaction.
domain_firstModel software around the business domain and its language, built with the people who know it best.
deliver_earlyCustomer-focused Agile: find what matters most, ship it early, and iterate on real feedback.
built_to_be_supportedScalable, maintainable systems, shaped by years of fixing them for enterprise customers.
