Iván Greve

Frontend Engineer

San Carlos de Bariloche, Argentina — remote

I build products end to end. For the last three years that has meant React, React Native and TypeScript at CookUnity, where I led a backoffice platform from scratch, designed the React design system the internal tools run on, and shipped the chef app to the App Store and Google Play.

Before that: Technical Lead on an Angular monolith in agribusiness, five years co-founding a Big Data and IoT product, and four years of .NET full stack. The frontend is where I do my best work — but I have shipped every layer under it, and it shows in the decisions I make.

Projects

All three read the physical world I live in: a mountain full of ski instructors, a house running off the grid, a maize field seen from orbit.

SnowRide

Book ski, snowboard and kitesurf lessons in Argentina and Chile

A two-sided marketplace: riders find an instructor on the map, filter by discipline, check the profile and book in seconds; instructors manage their calendar, sync it with Google Calendar and get paid. Expo app for both sides, plus a landing site.

solar-fs

Off-grid solar monitoring dashboard

A dashboard for Felicity Solar off-grid installations that keeps its own time-series database — 5-minute telemetry plus daily rollups — so it can answer what the vendor cloud cannot: real self-sufficiency, how much energy the backup generator actually contributed, battery charge balance and estimated fuel cost. Multi-user, with per-owner isolation.

Agro Alerta Plagas

Satellite-read pest risk, ranked by field

No orbital sensor can resolve a 3 mm insect. So instead of detecting pests, this answers the question an agronomist actually opens the week with — which field do I walk first? — by combining crop phenology measured from Sentinel-2, thermal accumulation from climate reanalysis, and trap counts from the monitoring network. Every number traces back to an image you can look at, on the date the model read it.
