Lucas Paraizo, product designer
I’m Lucas, a product designer in the UK, currently working on software for banks, custodians and hedge funds at Smartstream, where I also design AI features.
Outside work I make apps like Liber, Nossa and Magno. I use AI from first research through to final design and code, and I make the design calls myself. The best way to reach me is email.
Work
Sole designer on the corporate actions workflow for banks and custodians. I ran Smartstream’s first structured user research, which changed the brief from adding features to prioritising work, then tested prototypes with six client organisations and delivered the design ahead of schedule.
Owned product design for Aurora, Smartstream’s reconciliations and payments product, for over a year. One example is its new securities module: I co-led a two-day workshop in Vienna with development, QA, product and documentation, then designed how a security is created, found and read.
An iPhone app that turns the books you own into shelves. AI read competitors’ reviews, audited the add-a-book flow and drafted three competing designs. I chose one, took parts of the other two and set the motion and copy, and Claude Code and Codex write the code.
