Rethinking Infrastructure Efficiency
Reframing tool consolidation into a personalized operating system for 3,400 engineers

What is infrastructure efficiency?
Infrastructure efficiency is the process of identifying and recovering unused computing resources across Meta's infrastructure. The work saves hundreds of millions of dollars annually, but requires coordination across multiple teams, workflows, and decision makers.
Before designing anything, I mapped the entire efficiency lifecycle and the three user groups responsible for it. Understanding who did what, when, and why became the foundation for every design decision that followed.
Efficiency Lifecycle — Who Does What, and When
Where to focus
Find opportunities
Recover capacity
Validate impact
Return to pool
Budget Owners
Set targets, track compliance, reconcile fleet
Individual Engineers
Find, execute, and submit efficiency work
Platform Operators
Define rules, publish signals, monitor the fleet
The Problem
Over time, the tooling to support this lifecycle had grown into three separate products. Each had its own entry point, navigation logic, and definition of what mattered. Engineers had to move between systems to discover opportunities, submit completed work, and track progress.
Engineers trying to do efficiency work had to know which tool to open, hunt for what was relevant to them inside it, and context-switch repeatedly to make any progress. Most of the time, they skipped it.
The original brief was a logical response to visible friction: unify the three tools into a single surface. My job — in theory — was to design that experience.
I pushed back before writing a line of design.
“Unify the tools” was a product-centric frame.
Consolidation for its own sake moves complexity around; it doesn't solve the underlying problem.
Having designed multiple products across the efficiency ecosystem, I suspected the problem wasn't tool fragmentation alone.
Infrastructure budget owners needed org-level compliance signals. Individual engineers needed to find and complete assigned work. Platform operators needed fleet-wide visibility.
A single prescribed experience risked optimizing for none of them.
The question wasn't “how do we unify the tools?” It was:
“How do we make it effortless for each user to find their work, understand why it matters, and take the right next action?”
Validating the Hypothesis
Before running concept testing, I aligned ownership, decision authority, and success criteria across two product organizations with different roadmaps and incentives. I defined success as validated pain points, stakeholder alignment on strategic direction, and positive user response — not design deliverables.
From day one, I wanted leadership to understand that we were running discovery, not shipping a spec.
Hypothesis
The problem wasn't tool fragmentation.
It was relevance.
Different users needed fundamentally different information, surfaced in the context of their role, responsibilities, and goals.
Concept
A personalized efficiency experience — a configurable homepage and a contextual assistant — that could surface the right content, actions, and workflows for each user type while helping them complete work without switching tools.

The tested concept: a modular, role-aware homepage consolidating wins, reviews, opportunities, and compliance into one configurable surface

distinct user types
I wrote the interview scripts, recruited participants, and ran the sessions alongside our UX researcher — testing with engineers, reviewers, opportunity consumers, rule creators, platform operators, and efficiency leads.
The results strongly validated the direction. Participants consistently responded positively when the experience felt tailored to their role and workflow. Five themes emerged repeatedly: relevance, prioritization, actionability, impact visibility, and team alignment.
But the testing also sharpened the strategy. The differences between users weren't just preferences — they were systematic. Engineers wanted assigned opportunities and pending win submissions front and center. Budget owners wanted compliance status and org-level progress at a glance. Platform operators wanted fleet-wide signals and the health of their published rules. Even when users cared about the same underlying system, they needed entirely different information prioritized at the top.
No single layout served all of them. That finding wasn't a constraint — it was the design direction.

Regression View
Regression view was deferred, not dismissed — the module design was sound; test participants for that workflow weren't available during the session window.
“So far, I really like it because it feels like a unified place where I can come to view all things efficiency related.”
— Concept testing participant
The implication wasn't “build a single unified view.” It was “make each person's experience feel unified to them.” That's not a tool consolidation. That's a new product category — and it changed everything about what we were building.
Design Principles
Relevant
Surface content tailored to each user's role, domain, and goals
Flexible
Let users configure and arrange their view to fit how they actually work
Connected
Link workflows across the efficiency ecosystem instead of isolating them
Consistent
Make behavior predictable so users can navigate with confidence
Design Decisions
A home screen, not a dashboard
The mental model that unlocked the team's alignment: an iPhone home screen. All the apps exist. You decide which ones go where. The system suggests sensible defaults based on your role — but you control your view.
Early conversations naturally converged on a unified dashboard. The problem was that dashboards are built for monitoring — they work well when users come to read information. But users weren't opening the efficiency tools to consume reports. They were opening them to complete work: find an opportunity, submit a win, clear a compliance item. A home screen shifts the frame from reporting to action.
This became the foundational product principle: modular, configurable, persona-aware. Rather than designing a single page, I designed a system of configurable content blocks — a to-dos surface, a metrics summary, an opportunities module, a wins tracker, a review queue, and more. Each widget is self-contained and can be surfaced, collapsed, or repositioned based on the user's role and preferences.
Persona-aware defaults, not a blank canvas
Different user types start with different configurations. Individual engineers see their assigned work and pending submissions. Infrastructure budget owners see compliance status and org-level metrics. Platform operators see fleet-level signals. Users customize from there — the defaults reduce “blank canvas” friction without removing flexibility.
Full customization was the obvious alternative — give users complete control and let them build whatever they need. But concept testing made the tradeoff clear: users didn't want to configure a tool before they could use it. They expected the system to already understand their role. Persona-aware defaults deliver immediate value while preserving the flexibility to adjust.

Contextual AI assistance: meet users where they are
Finding the right work was only half the problem. The same insight that drove the homepage — that relevance means meeting each user in the context of their actual work — applied just as much to workflow completion. Once users identified an opportunity, completing it still required navigating complex workflows: submitting a win, calculating dollar impact, tracking a review, understanding an unfamiliar metric. Each step meant switching context or recalling process details from memory.
A standalone AI destination was on the table — a dedicated interface where users could query the efficiency system. But research had consistently surfaced workflow fragmentation and context switching as the core friction. Sending users to another tool, even a smarter one, would have recreated exactly what we were trying to solve. The assistant needed to be embedded in the experience, not alongside it.
I introduced Efficiency Assistant — a persistent, context-aware conversational widget embedded throughout the experience. The first version targeted four JTBDs at the intersection of high frequency, high friction, and high business impact:
- Record a win — guided submission without opening the full form flow
- Review wins — surface evidence and an AI-generated verdict so reviewers can decide without switching tools
- Summarize wins this half — on-demand summary of submitted and approved work
- Answer page questions — explain metrics, surface context, clarify status in place

AI-assisted win submission
Engineers often already had the evidence — an IsItFaster experiment had run, results were in, contributors were known. But translating that into a review-ready submission still required manually calculating impact, attributing contributors, and completing structured metadata. I explored how the assistant could handle that translation: paste an experiment link, and it retrieves the metadata, calculates annual savings, identifies contributors, and drafts a submission ready for review.
Why this mattered
The challenge wasn't content generation — it was converting infrastructure evidence into standardized business records. The assistant reduced that workflow into a guided conversation, with every field traceable to a source and every decision remaining with the engineer.
This was the same principle as the homepage applied to task completion: don't send users somewhere else to do their work. Bring the right capability to where they already are.
The to-dos widget: the right first proof of concept
Rather than building everything at once, I scoped the initial development phase around a single high-impact widget: a configurable task surface showing each user what they need to do next.
Other starting points existed — the opportunities module, the review queue, the AI-assisted workflows. But the to-dos widget was the only one that cut across every persona. Engineers had pending submissions. Budget owners had compliance tasks. Platform operators had blockers to clear. No other module had that kind of universal relevance.
This was the right first build — high value, bounded scope, and a direct answer to the most consistent research finding: “I don't know what to do when I open this.” The to-dos module pulls pending work from across the efficiency ecosystem — compliance items, efficiency wins needing review, high-value opportunities worth acting on — into a single actionable list. No tool-switching required.
It also established a proof of concept for the widget architecture before we committed engineering resources to building the full system.


What I Deliberately Didn't Build
A single unified dashboard. The temptation was real — a big combined view would have looked impressive in a demo and satisfied the original brief. But it would have failed in production for the same reason the original framing was wrong: different users need fundamentally different things, and designing to the average serves no one.
The research gave me the evidence to hold that position. Without it, the organizational pull toward a simple, demo-ready deliverable would have won.

The Leadership Signal
When I presented to senior leadership, they didn't ask to revisit the consolidation brief. They adopted the strategy. Engineering committed to building the full system — not a proof of concept, not a phased pilot — the whole thing. The team was genuinely excited. That kind of enthusiasm doesn't happen for a homepage redesign.
What shipped was Meta's first personalized experience in the capacity and efficiency ecosystem. Nothing like it had existed before. And because it established both the architecture and the design principles, it was positioned as the model for how future projects in the efficiency org should be built.
None of that happens without the conditions I created before a single pixel was designed. I wrote the strategy document that gave six stakeholders clarity on scope and ownership. I facilitated the cross-functional kickoff across two product organizations. I kept the project anchored to user needs when organizational momentum pushed toward a simpler deliverable. I co-authored the research plan, wrote the interview scripts, recruited participants, and ran the concept testing end-to-end.
The hardest part wasn't the design. It was making the case — early, consistently, with evidence — that the original framing was wrong, and that solving it right required more upfront investment than anyone had planned for.
My year-end manager review: “Set north star vision for Efficiency product ecosystem, securing H1 '26 commitment and presented to senior leadership to get buy-in.” The north star vision became the shipped product.
