The problem

Two ecosystems, constant context-switching

Analysts built data in Workstation and rich dashboards in Library — then had to leave PowerPoint or Excel to use them. Presenting a pitch meant minimizing the deck to open a live dashboard. Clunky, disruptive, unprofessional.

Our value proposition

A real-time sync engine, not an exporter

A bidirectional data bridge: live Library dashboards dropped into PowerPoint, raw datasets pulled into Excel. Edit the source in Workstation, click once in the add-in, and every visual and table updates on the fly — no manual rework.

Process — constraint vs. craft, five phases
01Discovery

Identifying enterprise pain points

Challenge

Analysts moved between separate ecosystems all day — a live pitch meant minimizing the deck to open a dashboard elsewhere.

Key actions

Sourced straight from Strategy's enterprise clients, who were vocal about the gap. I framed the north star: connect two completely different software ecosystems into one cohesive, professional workflow.

02Define

Technical scope & product constraints

Constraint

Office's JavaScript APIs and add-in behaviours set hard limits on what was technically possible.

Key actions

With the PM and PO, I ran technical-alignment talks with Microsoft's engineering team to map those APIs — then defined a bidirectional bridge over a flat image exporter. The killer feature: real-time sync that updates visuals and tables from a single click.

03Design

Mapping integration logic & lo-fi validation

Constraint

You don't own the canvas — the add-in had to fit gracefully inside Microsoft Office's rigid design system.

Key actions

I focused on structure over high-fidelity UI: user flows and low-fidelity wireframes for how the side-panel would behave, search for content, and display object data.

Global alignment — USA & China

Lo-fi wireframes were presented to, iterated with, and signed off by high-level stakeholders across two continents — ensuring the UX met global enterprise compliance and engineering capability.

04Prototype & Test

Validating “in battle” with end-users

Constraint

The connector had to feel native — handling prompt filters and dashboard scaling inside PowerPoint slides.

Key actions

I built interactive Figma prototypes mimicking the exact behaviour of an Office side-panel connector, then returned to the clients who first requested the feature.

In-battle user testing

In-depth interviews, exploratory sessions and A/B tests on how users browsed Library catalogs from inside Excel and PowerPoint. Watching analysts use it live surfaced the real friction — and we iterated on it immediately.

05Deliver

Cross-company agile & Design QA

Constraint

The add-in lived inside third-party environments — Office on web, Mac and Windows — with SAML/SSO auth and data integrity to hold across all of them.

Key actions

I worked inside a cross-functional squad — PM, Dev, QA — synced with Microsoft's design and technical teams, running meticulous Design QA against our layout parameters on every platform.

Cross-company agile partnership

Regular joint cross-company calls to plan incremental iterations, map deployment phases and troubleshoot technical edge cases on the fly — validating the production front-end against spec.

Why this project is a milestone
01
Beyond web & mobile

Designing invisible, seamless product logic for complex enterprise workflows — not standard screen layouts.

02
Big-tech constraints

Navigating Microsoft's Office APIs and rigid add-in guidelines, and partnering directly with their teams.

03
Global stakeholders

Aligning expectations and compliance across the USA and China through every iteration.

Leadership Philosophy — 03

Leadership

Product Lead Designer · running a design department

I run a design department — not just a backlog.

I own the product's experience end-to-end and grow the people who craft it. Leadership, to me, is holding the line between real user needs and business strategy — while building designers who outgrow the brief.

01Vision & ownership

End-to-end ownership of the product's UX

I hold the product's experience from strategy to ship, partnering daily with the CEO and our major clients. That seat lets me translate real user needs into decisions the business can rally behind — and keep design at the table where direction is set, not just where it's executed.

DailyStrategic alignment

Direct C-level & client collaboration, with full ownership of the product UX — bridging user needs and commercial goals.

02Team & talent

Growing designers, not just shipping screens

I lead a team of UX/UI designers and treat their growth as the work itself — shaping the craft, the standards and the careers behind every release.

1:1People growth & mentorship

Development paths tailored to each designer's passions and aligned to the company's OKRs — so personal ambition and business goals pull in the same direction.

End-to-endTeam scaling

Owning the full recruitment process — sourcing, interviewing and hiring — to scale the design org with the right talent as we grow.

AI Power User — Pragmatic Innovator

AI

Advanced AI integration · enterprise & independent

AI is my unfair advantage — on the clock and after hours.

I don't stop at basic prompts. I architect AI deep into how products are designed, built and run — turning raw capability into shipped features and measurable business ROI.

01Enterprise & client work

Shipping AI inside enterprise software

In my day job I design and implement advanced AI solutions — smart AI agents, interactive chatbots, and automation that removes heavy, manual user tasks. The goal: eliminate friction in complex enterprise tools and give people their time back.

02Venture & co-creation · FLEO

My passion, proven in production

My obsession with AI runs well past client work. FLEO — the studio I co-founded — is the ultimate proof-of-concept: my partner (Analytics & BI) and I run a heavily AI-augmented workflow to co-design and co-build conversion-focused business websites from scratch.
