Introduction

DevsData LLC partnered with Orange Charger, a San Francisco-based startup focused on improving home EV charging for multi-unit dwellings. Our team was responsible for end-to-end mobile app development, including backend architecture, frontend implementation, UX/UI design, and integration with Orange Charger’s hardware and payment systems. The result is a scalable system that simplifies EV charging for tenants, reduces administrative work for property owners, and supports Orange Charger’s expansion across multi-unit properties.

Client profile

Orange Charger builds practical home-charging systems for EV owners in multi-unit housing. Backed by a $6.5 million seed round, the company designs and manufactures 240-volt smart outlets that enable property owners to install and manage EV charging points on their premises.

With a growing team of around 40 employees, including former Tesla engineers, Orange Charger combines hardware innovation with intelligent software to simplify installation, billing, and energy monitoring for landlords and tenants alike. As a result, the company has enabled more multi-unit properties to offer reliable home charging, increased EV adoption among urban residents, and reduced the operational burden traditionally associated with managing shared charging infrastructure.

Highlights:

• Raised a $6.5 million seed round from early-stage investors.
• Employs approximately 40 specialists across engineering, design, and product development.
• Delivers smart EV charging solutions tailored for multi-unit and residential communities.

Challenge

As electric vehicle adoption accelerated across the United States, a significant share of potential users faced a common barrier – the lack of accessible charging options at home. Nearly half of urban residents live in multi-unit dwellings, where installing private chargers is often impractical due to shared electrical infrastructure, limited panel capacity, and complex permitting requirements. Orange Charger identified this gap early on but needed an advanced digital solution to connect hardware, property owners, and end users in a single, streamlined ecosystem.

Developing such a system presented both technical and operational challenges. The platform had to securely handle financial transactions between tenants and property owners, manage real-time energy consumption data, and synchronize with hardware devices across multiple buildings. Additionally, the app needed to support various user types – landlords, residents, and installers – each with different access levels and functionalities. Achieving this required seamless integration between backend architecture, mobile interfaces, and the hardware’s embedded systems.

Orange Charger’s internal team brought strong product expertise and a deep understanding of the EV industry, but they did not have the in-house engineering capacity required to build a full mobile ecosystem. Developing a secure, scalable application that integrates with physical charging units, payment systems, and real-time energy data would have required assembling a full software team – a process that is costly and slow for an early-stage startup. To accelerate time-to-market and focus internal resources on hardware development and deployment, the company decided to outsource the software layer to a specialist partner. DevsData LLC was selected to lead this effort, providing end-to-end mobile app development, technical consulting, and the engineering capabilities necessary to transform the charging concept into a fully operational digital platform.

Orange Charger needed a secure digital platform to connect property owners, tenants, and charging hardware, transforming a complex physical process into a seamless software-driven experience.

Our approach

After thoroughly analyzing Orange Charger’s concept, DevsData LLC began by mapping the ecosystem around hardware, property owners, and end users to identify critical integration points. Our primary goal was to create a platform that not only connected these parties securely but also provided a fluid user experience across devices. We knew from the outset that scalability, security, and compatibility with various hardware and billing systems would be essential to the project’s success.

Drawing on our experience from previous mobile development projects, including a retail and eCommerce application we built for a Pennsylvania-based client, we recognized the importance of establishing a strong architectural foundation early. In that project, our team successfully refactored legacy code, modernized the interface, and implemented advanced integrations with platforms like Magento and geolocation APIs. Those lessons proved valuable in the Orange Charger case, where we faced similar requirements for cross-platform consistency, real-time data exchange, and intuitive user navigation.

Our approach centered around four core principles:

Technical precision

We defined a detailed technical roadmap and system architecture to enable efficient data flow between the hardware layer, backend logic, and user-facing mobile applications.

Iterative collaboration

We maintained transparent communication with Orange Charger’s internal team through regular validation checkpoints, ensuring that each milestone aligned with evolving business objectives.

Future scalability

We designed the system with flexibility in mind, allowing for smooth implementation of upcoming features, such as Bluetooth-based charging activation and automated billing, without disrupting the existing ecosystem.

Business analysis and requirements management

We translated product goals into clear, structured requirements, helping the client prioritize features, refine user flows, and ensure that technical decisions supported both short-term needs and long-term business outcomes.

Execution and delivery

DevsData LLC developed the Orange Charger mobile platform from the ground up, covering backend architecture, frontend development, UX/UI design, and system integration. The project required a secure, scalable application that could support real-time energy monitoring, billing automation, and seamless interaction with physical charging hardware.

A dedicated five-person team led the project: a project manager, backend developer, frontend engineer, UX/UI designer, and QA specialist. This compact structure enabled fast communication, clear ownership of responsibilities, and efficient cooperation with Orange Charger’s hardware and product teams.

We began by designing a backend capable of handling high data throughput and reliable communication with the charging units. Authentication, payments, and real-time session tracking were implemented with a focus on security and consistency. On the frontend, our engineers built a cross-platform mobile application using Flutter, ensuring a smooth experience across devices. The interface allowed users to start charging sessions, monitor consumption, and access billing information with minimal friction. Property owners received tools for tracking energy usage and managing settlements. The UX/UI process focused on clarity and accessibility. Through multiple design iterations, we ensured that both tenants and landlords could navigate the application with ease. Bluetooth-based charging activation was introduced to reduce manual steps and streamline the user journey.

Throughout the project, our team worked closely with Orange Charger’s internal specialists not only on the technical layer but also on the broader business and project context. We incorporated product feedback into development cycles, aligned each release with evolving business goals, and ensured requirements were clearly defined and validated before implementation. Weekly touchpoints, sprint reviews, and roadmap sessions helped both sides stay synchronized, refine functionalities, and anticipate future needs. This collaborative model allowed us to maintain transparency around progress, timelines, and dependencies, ensuring the final product supported both the operational realities of EV charging hardware and the long-term strategic direction of Orange Charger.

Tech stack overview

The platform’s architecture combines several coordinated layers, outlined below, each contributing to a seamless charging experience for tenants and property owners.

Together, these components created a modular system in which each part – frontend, backend, hardware integration, and analytics – could be updated or expanded independently. This structure made it easier to add new features, refine existing ones, and maintain smooth interaction between the mobile app and charging hardware.

Outcome

The result of the collaboration between DevsData LLC and Orange Charger was a fully operational mobile platform that redefined how residential EV charging is managed. The final product seamlessly connected property owners, tenants, and charging infrastructure through a unified digital environment that is secure, scalable, and easy to maintain.
