A B2C fintech platform where users earn back their trading fees. We pulled the whole product in-house, web and mobile, and rebuilt it around speed.
Overview
The problem
We moved fast and solved the dependency problem, then created a performance one of our own.
The approach
SEO and per-route cache control, without an agency in the loop.
Native where interaction matters, WebView where content changes weekly, at ~90% shared code.
Wired in from day one, so “it feels slow” became a number we could move.
The result
Measured against our own v1, not the agency build. Two years of ownership: shipped in 2024, rebranded and overhauled across 2025-26.
Drove the core of both phases: the 2024 migration (App Router, the RN app) and the recent rebrand + performance overhaul, while the team of 3-4 handled product work in parallel. Set up the CI/CD and code-review standards still in use.
Aggressive caching vs. real-time trading data: static cached at the edge, price and balance bypass. Heavier requests, accepted only where staleness costs users money.
