Fixing Mobile Friction at Scale in a High-Growth Consumer Marketplace

For a leading consumer services marketplace, the mobile app sat at the center of the customer experience. It was how users searched, connected, and transacted for services that were often urgent, personal, and part of everyday life. When performance issues began to surface (latency, instability, friction in key user journeys), the business felt it immediately. Lorien embedded specialized mobile talent into the heart of the engineering organization, helping stabilize a critical platform and position it for scalable growth.

Why Lorien
Deep Mobile SpecializationLorien's track record in mobile engineering talent meant the team understood the niche — iOS, Android, React Native, mobile QA — and could build a targeted talent strategy around it, not just fill roles against a job description.
A Repeatable Talent PipelineRather than treating each placement as a standalone hire, Lorien built a dedicated mobile pipeline designed to shorten time-to-fill, improve fit, and give the business confidence that critical roles could be staffed quickly as demand grew.
Operational FlexibilityAs budget pressure increased, Lorien shifted portions of the model to nearshore resources in Mexico and Canada, reducing cost without sacrificing quality, and adapting the delivery model to meet the client where conditions required.
Close Partnership at Every LevelWorking alongside engineering, talent acquisition, and people leaders, Lorien moved from tactical support to strategic partner, helping align talent decisions with product delivery priorities across a multiyear engagement.
Situation

The mobile app was the product, and it was showing the strain of rapid growth.

This platform connects millions of people with the services they need for everyday life: a marketplace where interactions are often personal, time-sensitive, and tied to the routines families depend on. With more than 40 million users, the mobile application was not a feature of the product. It was the product.

As mobile usage continued to grow, performance issues were becoming harder to ignore. Latency, instability, and friction in key user journeys were creating a poorer experience for customers and placing pressure on product and engineering teams to respond quickly. The platform had legacy elements, parts of the mobile stack needed modernizing, and the business was balancing all of this against the need to keep releasing features and managing costs.

This was not a simple capacity problem. It was a business-critical effort to protect the user experience on a platform that tens of millions of people depended on, while simultaneously creating a stronger, more modern foundation for future growth.

Platform Users
40M+
At this user scale, mobile performance is not an engineering metric; it's a business outcome. Latency and instability don't stay inside the app; they surface immediately in customer behavior and retention.
Annual Revenue
$300M–$370M
A marketplace at this revenue scale cannot afford a mobile experience that erodes trust. Every friction point in a user journey is a retention risk, and a revenue one.
Challenge

The right engineers, for a complex environment, under real cost and time pressure.

The business needed more than additional headcount. It needed mobile specialists who could make an immediate impact in a legacy environment undergoing modernization — while the organization was simultaneously managing budget pressure, accelerating feature delivery, and working to stabilize a platform that couldn't afford further instability.

01
Specialized talent in a complex stack

The platform had legacy elements alongside a modernization push toward Swift on iOS, Kotlin on Android, and React Native for cross-platform development. Finding engineers who could navigate that combination (and contribute quickly) ruled out generalist approaches from the start.

02
Speed to productivity under onboarding friction

Early in the engagement, onboarding and system-access issues created additional delay, slowing how quickly new resources could become productive. The risk was compounded: not only did roles need to be filled fast, but the wrong hire (or a slow start) would set the modernization effort further back.

03
Cost, speed, and quality at the same time

Budget pressure meant the organization needed to do more with less, but not at the expense of the engineering quality that stabilization required. Accelerating speed to market, improving the app experience, and managing costs were not sequential priorities. They were simultaneous ones.

What made this hard was the combination. Any one of these challenges in isolation would have been manageable. Together — legacy modernization, onboarding friction, budget constraints, and the pressure to keep releasing features — they required a partner with both deep mobile expertise and the operational flexibility to adapt as conditions changed.

How Lorien approached the problem

Not isolated placements. A mobile talent strategy built around the client's actual delivery needs.

Lorien's engagement began with focused mobile support and widened as the client's priorities evolved. From the start, the approach was built around the specifics of the environment: a modernizing stack, an Agile team already moving at pace, and a business that needed contributors who could operate without a long runway to productivity.

Rather than treating each role as a standalone placement, the team built a repeatable mobile talent pipeline, one designed to shorten time-to-fill, improve fit over successive hires, and give the organization confidence that critical roles could be staffed quickly as demand grew. The pipeline covered iOS, Android, React Native, mobile QA, and adjacent engineering disciplines, ensuring coverage across the full scope of the modernization effort.

Critically, the model adapted as conditions changed. When onboarding barriers threatened to slow momentum, the team worked with the client to establish an internal contractor account, making interviews faster and removing access delays that had been limiting early productivity. When budget pressure increased, the model shifted to incorporate nearshore resources in Mexico and Canada, reducing cost while maintaining the engineering quality the platform required.

Mobile-first specialization. Coverage across iOS (Swift), Android (Kotlin), React Native, and mobile QA ensured every placement was matched to the specific needs of a modernizing, multi-discipline mobile environment.

Onboarding friction removed. When system-access issues slowed early productivity, Lorien worked with the client to establish an internal contractor account — making the interview and access process faster and reducing the lag between placement and contribution.

Nearshore cost flexibility. As budget pressure increased, portions of the model shifted to nearshore resources in Mexico and Canada — preserving engineering quality while reducing cost and giving the business more capacity to work with.

Solution

A dedicated mobile pipeline, embedded into the delivery team, scaled by trust.

Lorien provided specialized mobile talent across the full scope of the modernization effort — integrated into an Agile environment already moving at pace, and scaled progressively as the partnership deepened and delivery quality was demonstrated.

Engagement spanning mobile modernization, additional workstreams, and a subsidiary brand
From tactical support to strategic partner.

The engagement expanded well beyond its original scope (into additional workstreams and a subsidiary brand) because the delivery model earned that trust. By that point, Lorien was no longer simply a source of mobile engineers. It had become a partner helping the business align talent strategy with product delivery across a multiyear transformation.

A platform positioned for scalable growth.

The mobile experience became more stable. The platform was strengthened during a critical transition period, and the modernization work — Swift, Kotlin, React Native — created a more resilient foundation for the features and growth that followed. For a marketplace where the app is the product, that outcome was the one that mattered most.
