## About

Dario Espinosa is a Lead Experience Designer with 18+ years turning complex, outdated systems into clear, human experiences — across field operations, industrial software, enterprise platforms, telecom, healthcare, energy, analytics and spatial computing, from startups to Fortune 500 companies.

He prototypes in code with Claude and coding agents (Cursor, local LLMs), so stakeholders review a working interface from the first session. Research-grounded and systems-minded; accessibility (WCAG 2.1 AA) is core to how he works.

## Current role

Experience Design Lead — SoftServe (January 2025 – present): leading how design and AI-assisted workflows plug into each other across healthcare, energy and spatial computing.

## Case studies

### Replacing Legacy Tools: AI-Powered Blend Optimizer
Replacing a decades-old Excel model with an ML-driven web app that lets Plant Operations Managers optimize oil-well fluid formulas in minutes instead of hours. Designed using an AI-assisted prototyping workflow (Claude), reaching React-ready fidelity at v7.
Headline result: Excel replaced.
Industry: energy
URL: https://datadaeon.github.io/blendops.html

### Rebuilding Benefits Software
Leading UX for a from-scratch rebuild of a legacy employee-benefits platform, and building the code-first, AI-assisted workflow (HTML-to-Figma, connected requirements, a shared token system) that let a small, multinational team ship two full portals to WCAG 2.2 AA.
Headline result: v1.3→v1.8 iterations shipped.
Industry: enterprise-saas
URL: https://datadaeon.github.io/benefits-platform.html

### From Bid to Blacktop: One Field App for Three Different Jobs
Designing a mobile-first field platform for a national paving contractor — the sales bid, the dispatcher's desk, and the crew foreman's phone — through a forked, versioned prototyping pipeline a founder could click through without touching code.
Headline result: 8 versions shipped.
Industry: construction
URL: https://datadaeon.github.io/gradeline.html

### VOS — VIRTU4L Operations System with Local AI
A Slack-native operations brain for a real-world VR venue: daily checklists, reservations, sales tracking, and Dasha, an AI assistant running locally that handles what the team would otherwise forget.
Headline result: 293 tests passing.
Industry: entertainment
URL: https://datadaeon.github.io/virtu4lslacksagent.html

### Revolutionizing Data Insights: Dashboard Redesign
Introduced Double Track Agile and a consolidated Figma design system to a burned-out team. Feature delivery got 30% faster, and UX bugs dropped by half.
Headline result: +30% delivery speed.
Industry: analytics
URL: https://datadaeon.github.io/nielseniq.html

### Modernizing Railway Systems: Back Office Overhaul
After a fatal collision exposed a decades-old dispatcher tool, I led the full redesign solo — research, workflow restructuring, and a component-driven Figma + Flutter UI — with a direct line to the Product Director and no design committee in between. Operator task time dropped 40%, onboarding time 60%.
Headline result: −40% task time.
Industry: transportation
URL: https://datadaeon.github.io/siemens.html

### Digital Transformation: AEM & eCommerce Evolution
Led AT&T México’s five-year digital transformation across the flagship site, eCommerce platform, and dozens of microsites — including a 2021 AEM design system that moved seven teams from Photoshop into one shared Figma component library. Online sales rose 500%, with 96% accessibility compliance.
Headline result: +500% online sales.
Industry: telecommunications
URL: https://datadaeon.github.io/att.html

### From Philosophy to Digital Engagement: Life Coaching Platform
Turned a bestselling self-help book into a product people would actually open daily — not preachy, more like a coach than a checklist. ~50 interviews shaped a 7-area gamification framework behind a COVID-era pivot, shipped in 6 months.
Headline result: 7 life areas.
Industry: health & wellness
URL: https://datadaeon.github.io/oolalife.html

### Building a UX Powerhouse: Center of Excellence
First designer hired at a live healthcare SaaS platform with no design function. Built the UX practice and the product at the same time — the rebuilt admin flow now ships under one promise: “Manage benefits in under an hour per month.”
Headline result: +50% dev efficiency.
Industry: healthcare
URL: https://datadaeon.github.io/benefitbridge.html

### Exploring the Future: Metaverse Experience
Designed a fully navigable immersive exhibition for a major European tech convention in 4 months, using Spatial + Unity. It drew 1,500+ virtual visitors.
Headline result: 1,500+ visitors.
Industry: technology
URL: https://datadaeon.github.io/metaverse.html

### Optimizing User Research at Scale
Built scalable research guidelines and AI-assisted synthesis workflows across product verticals. Research turnaround dropped 50%, and cross-team adoption of the methodology followed.

Industry: construction
URL: https://datadaeon.github.io/research-at-scale.html
