At CGI, I lead day-to-day support for more than 70 finance applications across vendor-hosted and on-premise platforms. I maintain 99% service availability for critical SAP, BACS, and SAP PI services while supporting high-value financial transactions.

I’ve delivered more than 10 Power Automate initiatives that reduced response times by 60%, and I’ve used OpenAI tools to implement autonomous task-collaborating agents. I also delivered over 250 change requests with a 98% first-time approval rate and no high-severity implementation incidents.

Across Rathbones and JP Morgan Chase, I’ve provided advanced application support for investment management, trading, digital platform, and web applications. I’ve improved incident resolution through root cause analysis, proactive monitoring, release management, and AWS migration work.

I build capable support teams through documentation, knowledge transfer, mentoring, and technical hiring. I’ve mentored eight engineers, supported vendor management, and helped restore four critical applications within a week of a cyber-attack.
