Development of a native iOS MVP for a next-generation fulfillment platform. The project focused on "deskless" warehouse operations, integrating complex Bluetooth hardware (printers and scanners) to streamline shipping. The MVP launch validated the business model and helped the client secure their first round of investment.

Client: A US-based technology startup (Los Angeles) disrupting the traditional Third-Party Logistics (3PL) industry.

Industry: E-commerce Logistics / Supply Chain SaaS.

The Challenge: The client had a robust web platform for inventory and order management but lacked a solution for the physical "floor" operations. Warehouse staff and merchants were tethered to desktop stations to print shipping labels or verify inventory. To compete with legacy logistics giants, they needed to make their AI-driven fulfillment process mobile, fast, and completely transparent.

The client needed to:

• Move the fulfillment process from the desktop to the warehouse floor.

• Eliminate manual data entry errors through hardware integration.

• Create a seamless bridge between their AI cloud platform and physical devices (printers/scanners).

Our Role:

Senior iOS Development (Staff Augmentation). Build and launch a functional MVP (Minimum Viable Product) to validate the "Smart Fulfillment" hypothesis. Our team provided high-level technical expertise to lead the mobile engineering efforts.

A comprehensive audit and stabilization project for a mature iOS banking application. Over a six-month period, we resolved critical logic defects regarding financial calculations, eliminated crashes, and significantly reduced customer support overhead.

Client: A prominent financial institution operating across the Nordic region (Norway, Sweden, Denmark, Finland).

Industry: FinTech / Consumer Banking.

The Challenge: The client serves over 1.5 million customers, focusing on high-value products such as car finance, consumer loans, and savings accounts. Their native iOS application is a critical touchpoint for users to monitor repayments and invoices.

However, the application—built on a mature codebase—began suffering from "calculation drift" and UI inconsistencies.

• Data Integrity Issues: Users occasionally saw incorrect loan balances or invoice sums due to legacy logic errors.

• Support Bottleneck: The bank's customer support team was overwhelmed with tickets reporting "wrong numbers" in the app, preventing them from handling critical financial inquiries.

• Stability: Intermittent crashes were affecting user trust during login and transaction flows.

Our Role:

Technical Audit, Bug Fixing, and Logic Refactoring. Our team provided a Senior iOS Engineer to augment the client's internal mobile unit. The primary objective was not to add new features, but to perform a "Search and Rescue" operation on the existing codebase.

Development of a dual-application iOS ecosystem (Consumer & Driver) for an ultra-fast delivery startup. The project focused on advanced location tracking to enable a unique "moving inventory" business model, evolving from concept to a functional MVP for field testing in just 6 months.

Client: A dynamic startup based in the United Arab Emirates (UAE).

Industry: Q-Commerce (Quick Commerce) / Logistics.

The Challenge: The client aimed to disrupt the standard delivery model by offering extreme speed (delivery in 5-15 minutes). Unlike traditional e-commerce where users browse a static warehouse inventory, this model relied on roaming inventory.

The technical challenge was to build a system where:

• Users cannot order items unless a delivery vehicle carrying that specific stock is physically within their geofenced vicinity.

• Notifications must be triggered in real-time as the vehicle moves through neighborhoods.

• Synchronization between the driver’s location and the user’s app availability had to be precise to guarantee the 15-minute promise.

Our Role:

iOS Engineering (Staff Augmentation). Build a robust MVP to validate the "Store-on-Wheels" concept in a real-world environment. Our engineer joined the client's team to provide specialized iOS expertise, specifically focusing on complex location services and background processing.

Development of a high-performance native macOS application tailored for managing live audio during theatrical productions. The solution transformed a manual, error-prone process into a streamlined, professional workflow for a multi-disciplinary arts studio.

Client: A Children's Arts & Performance Studio based in Chicago, IL.

Industry: Performing Arts Education (Dance, Acting, Vocals) / Live Entertainment.

The Challenge: The client produces frequent live showcases involving complex audio requirements, including backing tracks, sound effects (SFX), and voice-overs. Previously, the production team relied on generic media players and standard file systems to run shows. This led to:

• High cognitive load: The producer had to manually hunt for files during live shows.

• Lack of precision: Difficulty in triggering precise sound effects or transitioning between tracks smoothly.

• Inflexibility: No easy way to create "chains" of audio or adjust specific sound parameters on the fly without navigating deep menus.

The client needed a bespoke macOS solution to professionalize their audio control booth and ensure flawless live performances.

Our Role:

End-to-end native macOS development. Create a stable, responsive macOS application that replaces the client’s existing manual playback methods. Our team was tasked with building a robust audio engine wrapped in an intuitive user interface from the ground up.

A targeted 2-month engagement to resolve critical media playback issues and architect next-generation iOS features for a market-leading FemTech application. We bridged the gap between a React Native core and complex native iOS capabilities.

Client: A leading UK-based fitness technology company.

Industry: Health & Wellness / FemTech.

The Challenge: The client operates a high-traffic React Native application that relies heavily on video content for workout guidance. While the core app structure was cross-platform, the video player required a high-performance native implementation. The client faced specific technical bottlenecks:

• Audio Conflicts: Users could not listen to their own music (Spotify/Apple Music) while listening to the in-app voice guidance.

• UX Gaps: Missing standard iOS media features like AirPlay and Picture-in-Picture (PiP), which are critical for home workouts.

• Innovation Block: The team wanted to implement iOS Live Activities and Dynamic Island features but lacked the specific native expertise to integrate these with their React Native architecture.

Our Role:

Native iOS Expertise / Staff Augmentation. Our team was brought in as a specialized task force to perform deep-dive debugging and R&D.

A comprehensive refactoring and UX optimization of the Apple CarPlay integration for a leading global audio streaming service. Over a 6-month period, we stabilized playback, streamlined navigation, and resolved critical synchronization issues, directly improving the driving experience for millions of users.

Client: A market-leading digital audio aggregator based in North America.

Industry: Media & Entertainment / Music Streaming.

The Challenge: Despite a large user base, the CarPlay experience was suffering from technical debt and usability friction. User reviews and crash logs highlighted several critical issues:

• Playback Instability: Audio often failed to resume automatically when the car started or switched sources.

• Session Loss: Users were unexpectedly logged out or lost their playback context during updates or connectivity drops.

• Sync Issues: "Car Presets" (favorites saved on the phone) often failed to appear or sync correctly on the dashboard.

• Distracted Driving Risks: Deep navigation hierarchies required too many taps to find content.

Our Role:

Senior iOS Development (Staff Augmentation). Our team provided specialized iOS expertise to tackle these stability and UX challenges.
