Where money has to add up
Products real customers use every day. Here, the answer has to be the same every time.
Fintech product
I designed and built KOIN on my own, from the ground up: an app tailored to BMSC, the largest private bank in Bolivia, that brings together card payments, digital wallets, yields on interest-bearing accounts, and our Crypto as a Service and fiat ramp platforms. Since its recent launch it already serves 5,000+ users and processes thousands of transactions a day with concurrent tasks.
Payment rails
I was part of the team that designed and built our fiat on- and off-ramps, with a focus on ARS: the path pesos take into and out of the platform, including the exchange with COELSA, Argentina’s electronic clearing house.
Crypto infrastructure
I was part of the team that designed and built a Crypto as a Service platform: the rails and API that let other companies add crypto wallets to their own apps without building them from scratch, with deposits and withdrawals, buying, selling and trading, and yields.
Where nothing is certain until measured
Qubits and quantum algorithms, brought into focus.
Quantum computing is hard to get into, and harder still if you want to learn it in Spanish.
So I built Qudos: an open, collaborative resource with theory, interactive simulations and code.
It became my thesis, and it’s live and open source for anyone to explore.
About
I’m Facundo, a computer scientist in Buenos Aires. My day job is software that can’t be off by a cent: payments, wallets, balances. My thesis went the other way, into quantum computing, where an answer is a probability until you measure it.
On my team, I’m the one front-end, app and backend developers turn to with technical questions: I design the solutions, decide how we integrate with providers and shape the financial flows. Financial products taught me to treat correctness as a feature; the thesis left me curious about what comes next.
