Ledgerwise — Enterprise Treasury Co-Pilot

The spark for this project came from a conversation with a friend who runs his own business. He was dealing with a lot of international transactions and felt completely overwhelmed by the fluctuating exchange rates and messy transaction files. He told me he just wanted a simple way to get a clear, safe overview of his accounts before he blindly handed everything off to his accountant. I realized there was a massive gap in the market: small businesses don't always need massive, expensive accounting software suites just to see where they stand. They just need a fast, private tool to calculate their exposures and give them peace of mind in seconds. That is why I built Ledgerwise.

To solve this, I architected a zero-trust, stateless B2B treasury co-pilot. Instead of forcing backend server instances to ingest and parse massive, sensitive financial ledgers, I shifted the computational burden entirely to the edge. Using PapaParse, the application compiles and aggregates the raw CSV data strictly within the client's browser. The server only receives lightweight JSON payloads, which are instantaneously cross-referenced with live global spot rates via the Frankfurter API and analyzed by a Groq-powered LLM. This decoupled, asynchronous approach guarantees data privacy while ensuring the platform can absorb massive concurrency spikes without hitting downstream token limits.
