Strategic Design Internship

Project 1: Assisted Tax Service

Reducing pre-appointment drop-off by designing a concierge experience

Role

Service designer

Timeline

Jul - Aug, 2025
(8 weeks)

Skills

Research

Strategy

Stakeholder alignment

Team

2 Designers

6 Business consultants

3 Partners

Business challenge

Customers were disengaging before their first appointment, losing the chance to convert interest into revenue

Solution

Fintech Co was launching a new “Concierge” role to support Assisted tax filers

What I worked on

I supported on defining the future state of how customers will be connected to tax experts

My impact

I defined key Moments of Truth, aligning cross-functional stakeholders, shaping pilot scope and the concierge training rollout

I developed a future-state journey map that was adopted across CX, CRM, Product, and Ops, and directly informed PRD development

I structured a phased tech capability roadmap tied to the future-state journey, which translated into buildable requirements for Engineering and PM

Results

  • Successfully launched pilot and launched concierge training
  • Enabled phase 2 to roll out and extend company’s partnership contract with client

Learnings

Research as foundation, not decoration

At Bain, "Has research been done?" was asked constantly. Whether it be previous case work, expert calls with competitors, or secondary research, working from validated research was the fastest way to become an expert in an unfamiliar space.

Speaking the language of stakeholders to influence design

Instead of presenting a journey map as a UX artifact, I framed it as an operating model and connected it to business impact. Influencing design often starts with creating clarity on how the design work supports others.

Project 2: 3D Modeling for Engineers

Simplifying how engineers go from concept to 3D model

Role

Product designer

Timeline

Aug 2025
(3 weeks)

Skills

Rapid prototyping

User testing

Collaboration

Team

2 Designers

2 Product strategists

5 Engineers

Business challenge

Designing electrical substations is a slow, manual process that costs the business
Designing electrical substations begins with a single line diagram (SLD) — a 2D logical representation of electrical systems

To move into production, engineers must manually translate that diagram into a detailed 3D CAD model

Solution

An internal digital tool that enables engineers to transform a SLD into a CAD-ready layout through an interactive, guided modeling flow

What I worked on

I drove early-stage product discovery through rapid prototyping and user testing to define the product’s core interaction model

My contributions

Defined and iterated on the end-to-end core flow through 7 iterations, earning green light from clients to move into high-fidelity

Pioneered an interactive map allowing engineers to:

  • Drag and place equipment

  • Automatically validate compatibility

  • Visually map SLD logic to physical layout

Reflection

Compatability is a UX problem, not just an engineering footnote

Compatability is not just defined by technical constraints, instead user research informs on mental models and behaviors that shape the affordances and functionality of the final product

Learning when to trust user input and when to challenge it

Product discovery is about uncovering underlying needs, and often times users' initial feedback is about feature requests and nice-to-haves. The challenge lies in differentiating between how users actually work apart from blue-sky ideals
