AARON
PIMENTIL
Lead User Experience Designer
19 years designing high-stakes systems across oil and gas, healthcare, and SaaS. Years onsite with SMEs, drillers and engineers, building real-time analytics and design systems from scratch. AI's part of my process too, turning transcripts into personas and workflow, not a side tool.
What I bring
to the table.
UX Strategy & Vision
Connecting product direction to user needs through roadmap alignment, workshop facilitation, and decision frameworks that de-risk releases.
Design Systems
Building scalable component libraries, design tokens, responsive constraints, and UI guidelines that accelerate delivery and improve consistency at scale.
Cross-Platform Design
Native iOS, Android, and web experiences — with deep fluency in platform conventions, mobile-first patterns, and unified design languages.
Implementation-Ready Specs
Producing testable acceptance criteria, annotated handoffs, and interaction documentation that eliminate ambiguity and reduce developer questions.
User Research & Testing
Discovery, heuristic evaluation, usability testing, journey mapping, and translating findings into prioritized, actionable design direction.
Data-Informed Design
Designing enterprise analytics dashboards and real-time visualization systems for complex, high-stakes operational environments.
Subscription & PLG Architecture
Architecting multi-tier subscription flows with upgrade boundaries, feature gating, and cross-platform behavioral consistency.
Mentorship & Team Development
Elevating team craft through structured critique, design methodology coaching, and building the next generation of UX practitioners — including as Rice University boot camp lead instructor.
AI-Augmented Workflow
Integrating Claude, Perplexity, Cursor, Notion AI, MidJourney, Sora, and Manus across research synthesis, prototyping, asset production, prompt engineering, and documentation — compressing timelines without sacrificing craft.
Case Studies.
Multi-Tier Sports Live Streaming, Scoring, & Recruiting Platform Redesign
Led end-to-end UX for AthletesGoLive 2.0 — a complete platform overhaul across live streaming, athlete profiles, team management, and a four-tier subscription architecture (Free, Fan+, Athlete+, Pro) on iOS, Android, and web.
DBS & DBA: Persona Research and Product Prioritization
Paused a 2D and 3D wellbore viewer already in design to run 12 structured interviews across DBS telemetry and DBA calculation trust. The research showed the viewer was Served Right, not Under-Served, and reset the roadmap around the problems that scored Critical instead: handoff standardization, alarm consistency, and calculation transparency.
iCruise CX — Sperry Drilling’s First Mobile App
Designed Sperry Drilling’s first mobile app for the iCruise CX rotary steerable system — a field-facing iOS/Android tool enabling engineers to execute precise hydraulic downlink sequences for autonomous directional drilling across 12+ design iterations.
UI Style Guide & Brand Consistency Initiative
Self-initiated audit of 4 Sperry Drilling enterprise apps (AutoGS, iTom, LOGIX, RoxC Blast), eliminating 51 color inconsistencies and delivering a unified UI Style Guide adopted org-wide.
The Pulse Intranet Redesign
Led end-to-end UX for The Pulse — Kelsey-Seybold’s internal intranet for 3,000+ nurses, administrators, technicians, and 480 physicians across 25 locations. Defined IA, navigation, wireframes, and prototypes through MoSCoW-facilitated workshops.
NOVOS: Alarm Center and Well Plan Import
Joined the NOVOS product team midstream on a short-term contract to design two features from scratch: a multi-state alarm notification center for rig floor alert fatigue, and a directional well plan import interface housing nine columns of precision survey data. Both shipped as developer-ready spec sheets.
Craft meets
strategy.
Leadership
“I don’t trade craft for scale — I use systems thinking to do both.”
Lead UX designer based in Houston, Texas, with 19+ years designing enterprise and consumer digital products across manufacturing, SaaS, healthcare, and oil & gas. My differentiator: I stay hands-on while scaling design influence through systems, mentorship, and operational clarity.
From architecting multi-tier subscription experiences for AthletesGoLive’s cross-platform mobile product to delivering NOV Max Platform’s real-time analytics visualizations, Halliburton’s first mobile directional drilling app, and a full clinical intranet for 3,000+ Kelsey-Seybold staff — I produce implementation-ready specs and scalable design systems that reduce engineering ambiguity and accelerate delivery.
I run an AI-assisted workflow across research synthesis, concepting, and documentation using Claude, Perplexity, Cursor, and others. It compresses timelines. It does not replace the thinking.

Designing at
AI speed.
“AI doesn’t replace my craft — it compresses timelines so I can do more of it.”
I’ve integrated a full AI-augmented workflow across every phase of UX — from AI-assisted research synthesis and competitive analysis to rapid prototype generation, asset production, and delivery documentation.
This means I can move from insight to implementation-ready spec faster than traditional timelines — without sacrificing the depth of thinking that good UX requires. I use AI as a force multiplier, not a crutch.
Prompt engineering, iterative refinement, and intelligent tooling are now core competencies I bring to every team I join.
Foundation
built right.
