The idea behind Fingo was genuinely interesting — not just another stock tracker, but a platform where financial awareness and social connection lived in the same place. Users could follow stocks, track market movements, and discuss what they were seeing with their network. Finance meets social feed.
I joined as part of the development team and spent six months contributing to what became one of the more complex React Native projects I'd worked on at that point.
What I Worked On
My primary focus was the stock exchange integration — connecting the app to external financial data sources so live market data flowed cleanly into the UI. Financial APIs come with their own quirks: rate limits, data formatting inconsistencies, latency considerations. Getting that layer to feel seamless from the user's side required careful handling underneath.
I also contributed to the interface design where social features and financial data had to coexist without feeling cluttered. That's a real design challenge. Stock data is dense. Social feeds are dynamic. Making both feel at home on the same screen takes deliberate thought.
Shipping to Production
Fingo was successfully deployed to the Google Play Store — my first experience taking a product through the full cycle to public release as part of a professional team. That process taught me things personal projects simply can't: code reviews, team coordination, handling feedback across disciplines, and the particular pressure of shipping something real users would download and judge.
What I Took Away
Six months on a team-built, production-shipped product changes how you think about code. You stop writing just for yourself and start writing for the person who has to read and maintain it after you. You learn to communicate about technical decisions, not just make them. You get a much clearer picture of what professional development actually looks like day to day.
Fingo was a private project — no screenshots or code due to company privacy. But the experience it gave me was anything but invisible.
