Capabilities
The lede
A growing SaaS company had outgrown manual product data management — performance bottlenecks, stale pricing, and increasing operational overhead as traffic scaled. They required a high-performance price comparison platform capable of processing massive product datasets.
Objectives
Approach
Performance-first, systems-driven engineering — intelligent automation, scalable architecture, operational resilience. Rather than layering optimisations onto a fragile monolith, we re-architected the platform around automated data flows, performance isolation, and horizontal scalability — immediate gains and long-term flexibility, both.
→ These improvements let the client scale affiliate traffic without increasing headcount, onboard new data sources rapidly, and operate confidently during high-traffic promotional periods without risking performance or revenue.
Engineering highlights
Data architecture
Dual-database system using MongoDB for persistence and Redis for sub-millisecond queries
Search infrastructure
Advanced full-text and faceted search with dynamic filtering and real-time indexing
Automation pipeline
Intelligent ETL with automated scraping, validation, and enrichment
API design
Headless, RESTful architecture enabling flexible frontend and partner integrations
Performance optimisation
Sub-second query responses through intelligent caching and indexing
Infrastructure
Containerised microservices with automated scaling and deployment pipelines

Reflection
Intelligent system design and automation can turn data-heavy platforms into self-optimising business assets. By focusing on automation, performance isolation, and scalable architecture from day one, we delivered a system that works smarter — not harder.
