Technical Lead building Temenos banking and payment orchestration platforms on AWS.
PortugalWhat I'm looking for
I lead end-to-end technical delivery for concurrent Temenos initiatives at UST, including Temenos online banking and mobile capabilities in production. I supervise multiple tech leads, partner with PMs and QA, and own go-live execution across weekly production deployments.
Earlier, I shaped a microservices SaaS ecosystem at DWF Sistemas e Automação, implementing JWT-based SSO and operating AWS for availability and scale. I’ve also handled critical production recovery when inheriting a troubled handover, and I mentor engineers through blockers and technical ambiguity.
