Executive Summary
In this case study I will explain the technical architecture research and backend strategy evaluation conducted for a mobile platform, The client had frontend and mobile development capability but no prior experience with native backends and no awareness of the available integration options for core integration on mobile. As the sole technical researcher, I was responsible for discovering and evaluating the possible solutions, reverse engineering how market leaders built their custom core integrations and audited a centralized core distribution platform as an alternative possibility. I delivered a comparative analysis covering implementation complexity, performance, core breadth, and platform specific optimization, alongside a concrete integration roadmap and engineering KPI framework. The research provided the client with a complete map of their options, from custom core management to centralized core distribution, enabling them to make an informed decision with defined success criteria before writing a single line of code.
The Problem
The client needed to integrate specialized computational modules into a mobile application. While they had the frontend and mobile development capabilities, they had no prior experience with the low-level native backends required for this domain, and were unaware of available integration options: whether to build custom adapters for each module or utilize an existing platform.
The Research
I evaluated to primary architectural options:
- Custom core integration: Manually integrating individual modules like how other solutions used to achieve specific platform optimization.
- Centralized core distribution: Use a pre-built platform that provides broad coverage via a standardized API.
I audited the platform's API, documentation and distribution platform. I also reverse-engineered public implementations of market-leading custom integrations to understand their optimization strategies and maintenance overhead.
The Analysis
| Client Priority | Best Fit | Risk |
|---|---|---|
| Easy module breadth | Managed Platform | Vendor lock-in |
| Maximum Performance | Custom Integration | Maintenance burden |
| Small team, no low-level expertise | Managed Platform | Documentation gaps |
| Long-term ownership | Custom Integration | Time cost |
Platform Specifics
The centralized platform exposes a C-based API with core files distributed via nightly build pipelines. The integration itself to the mobile native stack required a creating a language bridge between the platform's API and the mobile code.
Backend Research
Using pre-built cores from the platform, it is possible to power the application backend without messing with each module's source individually. The platform itself supports significantly more modules compared to the custom approaches, though the platform specific optimization data is known.
Key Differences
Centralized Platform
- Centralized and standardized, allowing for broader module support with less manual overhead.
Custom Integration
- Managing each core manually could theoretically yield better performance and tighter platform integration.
- Requires significantly more time and engineering investment.
Deliverables
- Comparative architecture analysis (custom vs pre-made)
- Integration roadmap with language bridging strategy
- Platform specific API documentation.
- Authentication provider evaluation (functional requirements only)
- Engineering KPI framework
Outcome
The client received the complete analysis for their backend options, from custom core handling, to ready-made platforms, along with measurable success criteria. This allowed them to make an informed decision before committing any resources.
