Custom Software · Engineering-Led Since 2015
Twimbox designs, builds, and operates production platforms — live GPS tracking for 50,000-person field crews, EMR scheduling and payments at hospital scale, and real-money transaction systems — and stays hands-on through day-to-day operation.
Selected Work
Built starting in 2015 (547 commits on record) as a courier and field-workforce coordination platform: native Android/iPhone apps, live GPS tracking, integrated payments, and SMS/push notifications. The tracking and coordination engine was later acquired by Ema Servicios and repurposed to coordinate approximately 50,000 field technicians reading electricity, gas, and water meters across Argentina. Twimbox ran operations for 3 years post-acquisition.

Real-money payments and subscription platform — partners bring paying subscribers into their groups.

Who We Are
Twimbox is led by engineers who have shipped and operated production software since 2015 — verifiable through 547 version-controlled commits on the Enviozapp platform alone. Our leadership spans platform architecture & security, financial operations, IT, customer support, and project management, drawing on a network of specialists across our active ventures.
We take on a small number of engagements at a time, staying hands-on from architecture through day-to-day operation — the same platforms we build are the ones we run.
