Four cases that sum up
what I do: system, scale, impact.

ZePOS
01 / 04 · Product Designer UX/UI · Retail POS · Mexico & Brazil
200 stores, zero downtime —
redesigning a POS to scale.
The system crashed during Hot Sale. Over 8 months, I redesigned end-to-end the architecture, catalog, cart, payments, and shipping — launching before Buen Fin 2024 across 200+ stores with zero incidents.

InsightOne
02 / 04 · UX/UI Designer · Software · U.S.A.
From visual chaos to
InsightOne's first Design System.
A payment platform with no design system — every screen was a new decision. I led the full redesign and built the company's first Design System, coordinating teams across time zones and aligning business, product, and engineering.

Clue
03 / 04 · UX/UI Designer · Mobile Health · Sep–Nov 2023
What the data wasn't showing:
UX research on Clue.
Users were dropping off Clue — but no one knew why. I led an end-to-end UX analysis: benchmarking, heuristic evaluation, and testing with real users. Result: hidden friction in onboarding and navigation flows that had never been documented.

Palm & Rescycle
04 / 04 · Product Designer · Startup · Colombia
From idea to validated product
in 8 weeks.
Palm & Rescycle needed a product that could convince users and investors. I led the full process — research, architecture, UX writing, prototyping, and testing — under Agile/Scrum with weekly deliveries. Result: −25% bounce rate, +15% user retention, and −20% development time.

About

Melany Olivares
UX/UI Product Designer · Remote

Hi, I'm Mel.

Product Designer with 4+ years building digital products at the intersection of user needs, business goals, and technical constraints — across payment platforms, e-commerce, and omnichannel systems.

Specialized in complex systems and scalable transactional experiences. I collaborate with engineering, product, and cross-functional teams — from discovery through delivery — using research, design systems, and data-informed decision-making.

Before product design, I spent a decade in public policy and consulting, leading multi-sector projects. That's where my ease with negotiation, facilitation, and stakeholder alignment comes from — something no design process teaches on its own.

01
I think in systems before I think in screens
Tokens, components, variants. A design that can't maintain itself isn't finished.
02
Performance is also UX
Load times, availability, and reliability are part of the experience. A slow system is a design problem.
03
I actually use AI, I don't just sell it
Claude, Figma MCP, Copilot. Tools that speed up the loop from idea to working prototype.
04
Decisions validated with research and data
Interviews, PostHog, Sentry, Grafana. Intuition is not a design plan.
