I build polished, complex product interfaces.

I turn product and design thinking into React and TypeScript front ends — dashboards, SaaS consoles and design systems where density, state and accessibility all have to hold at once.

Selected work

All projects →

Three featured projects; the full index is one click away. All self-directed showcase work — designed and built end to end to explore specific frontend problems. No client claims, no invented metrics.

Resolve support inbox: 214 open tickets with priority, SLA countdowns, queue rail and bulk actions
CASE / 01

Resolve

A support operations platform where a shift lead lives in one screen all day. Omnichannel intake, SLA-aware queues, rule-based routing, escalation into engineering, and a knowledge base drafted from tickets that were already solved.

Merchanta marketplace catalogue: filtered packaging supplies with tier pricing, minimum order quantities and RFQ actions
CASE / 02

Merchanta

Wholesale purchasing end to end, for the buying side and the selling side at once. Tier pricing and minimum order quantities, multi-supplier bulk orders, RFQ negotiation with an audit trail, and a vendor portal reading the same price list.

EVIDENCE · 01

A quote round is a row: list, requested and countered price side by side, so a negotiation can still be read months later.

CASE / 03

Aurelia

A sales experience for twenty-eight private residences in Lisbon, where the product is a photograph, an area and an aspect. Bedrooms, collection and outlook drive the filtering; every home resolves to a page an advisor can send.

EVIDENCE · 02

The appointment request is three steps on one screen — date, time, details. It is the only conversion the site has.

What I actually do

01

Product interfaces

Dense, stateful screens — inboxes, tables, editors — that stay legible under real data.

02

Design systems

Token architecture, component APIs and documentation that teams can extend without me.

03

Frontend architecture

State boundaries, data-fetching strategy and rendering choices that keep bundles honest.

04

Interaction & motion

Purposeful transitions and optimistic feedback, specified as tokens rather than improvised.

05

Accessibility

WCAG 2.2 AA as a floor: keyboard models for complex widgets and focus that survives refactors.

06

Design-to-code

Taking a file — or a rough direction — to a faithful, maintainable implementation.

Have an interface that has to hold up?

Product teams, design systems, and rescues of front ends that outgrew their first architecture.
