Toni Liquid Metal Environment Mobile
Product Designer & Full-Stack Engineer

I turn evidence into working products.

I work across product strategy, interaction design, full-stack engineering, backend systems, and applied AI—taking ambiguous problems from research through production.

HOW I WORK

Design Operating System.

01

DISCOVER

Research the user, business problem, operational constraints, and measurable success criteria. I turn ambiguous problems into clear goals.

02

EXPLORE

Turn evidence into workflows, information architecture, prototypes, and API boundaries. We validate interaction models before heavy engineering.

03

MAKE

Implement the interface, backend services, integrations, data models, and AI workflows. I write production code that scales securely.

04

DELIVER & LEARN

Test usability, analytics, edge cases, and failure paths. We release with explicit acceptance criteria and document real-world feedback.

Core Competencies

Capabilities

I build complex digital products end-to-end, from product strategy and user experience to backend services, data models, APIs, and production deployment.

Product Design & Strategy

Full-Stack & Backend Systems

I move from interface behavior into production architecture—building frontend experiences, APIs, state machines, data models, integrations, and failure-aware backend services.

Delivery & Systems Thinking

I connect product goals to architecture, implementation, measurement, and release—owning the path from requirements to production rather than stopping at handoff.
