Client Vision

The client, an outdoor sporting goods company in the fishing industry, was expanding beyond its established freshwater lure manufacturing into technology enabled fishing - data-collection devices, guided experiences, learning and logging, and social integrations. Its ambition was to become a true platform company, with multiple connected products and services spanning the full fishing ecosystem.

To realise that vision, the client needed a scalable, modular technology foundation that could support many product lines over time and a clear architecture and roadmap to get there.

02

Challenge

Two challenges were central to making the experience reliable in real-world conditions:

Offline Voice & NLP

Natural-language processing needs training data and, here, also had to run offline on the device. We evaluated and selected the Sensory SDK to provide on-device NLP and voice recognition that works without connectivity.

Reliable Environmental Data  

The experience depended on trustworthy geological and environmental inputs - the moon’s position, wind direction, speed, and pressure which required identifying and integrating dependable third-party data services

03

Solution

We defined the platform around a set of clear building blocks, designed as independent, scalable services:

A mobile application that interacts directly with the IoT device.

On-device NLP to translate voice into text data within the mobile app, including offline.

GPS and third-party integrations to track location and environmental conditions.

A cloud backend that ingests and synchronises the data collected through the mobile device.

These building blocks were realised as a microservices and API platform, allowing each capability - logging, location, social, notifications to scale and evolve independently as new product lines are added.

04

Our Approach

We partnered with the client from strategy through engineering, executing in structured phases.

Phase 1: Product Strategy & Roadmap

We translated the platform vision into a prioritised product roadmap, defining the services and capabilities that would make up the fishing-ecosystem platform.

Phase 2: Architecture Design

We designed a microservices and API architecture that supports independent scaling, online/offline operation, and the addition of new product lines over time.

Phase 3: Build & Integration

We built the Python microservices, the React Native mobile app with offline voice-to-text, and the third-party integrations for location and environmental data.

Phase 4: Performance, DevOps & QA

We hardened the platform with distributed caching, container orchestration, automated CI/CD, and structured project and test management.

Result / Impact

For the Client

  • Microservices and APIs developed in Python, giving each capability an independent, scalable service boundary.
  • Kubernetes used to orchestrate Docker containers for reliable, scalable deployment.
  • Elasticsearch set up for indexed data storage powering fast API responses.
  • ~3x faster delivery of new features through decoupled services and automated CI/CD

For End Users

  • Hands-free voice interface that records and queries data, working in both online and offline scenarios.
  • Distributed caching with Redis implemented as part of performance tuning for responsive interactions.
  • ~40% faster data access through distributed caching and indexed search
  • Real-time location and environmental context (GPS, wind, pressure, moon position) via integrated third-party services.

For the Business

  • Push-notification management delivered through Firebase and Amazon SNS.
  • DevOps integration implemented with Jenkins; JIRA for project management and QMetry for test management.
  • A reusable API and microservices platform that supports multiple product and service lines across the fishing ecosystem
  • Foundation ready to scale toward 100k+ users without re-architecting

Why It Matters

For an emerging platform company, the architecture decided early either accelerates every future product or quietly constrains it. By designing a modular microservices and API platform with offline-capable voice on the edge, dependable environmental data, and a scalable cloud backend - the client gained more than a single device: it gained a foundation it can extend across the entire fishing ecosystem. The work turned an ambitious product idea into a durable, scalable platform ready to grow with the business.
