Technical Electronic Medical Band (TEMB)
MedTech startup · ML Engineer and CTO · Kyiv, 2022–2023
On the battlefield every second counts. A wounded soldier may be unconscious when medics arrive, and without immediate access to allergies, blood type or chronic conditions they have to treat blind. Civilians in emergencies face the same problem.
TEMB put that information within reach. We built a compact token with a QR code linked to an electronic medical card, so critical health data can be read in seconds. The token is designed to be durable, reliable and easy to carry in any environment.
The first version was a centralised system on AWS backed by MySQL. It was presented at the Innovative Defence Initiative hackathon, supported by the Ministry of Defence of Ukraine, where it won a grant, and it was selected as one of 12 Ukrainian startups to pitch at Clare College, University of Cambridge. The aim was to digitise the whole casualty evacuation process using readily available technology.
As technical lead I designed and built the system’s architecture. I also ran structured interviews with military medics and field personnel to define evacuation requirements, and analysed data across evacuation windows. That analysis identified a compact set of physiological indicators whose availability raised survival probability by 35%, which shaped what the token stores.
The centralised design had real limits. Sensitive military data needs a level of security the system could not fully meet under Ministry of Defence standards, and a single point of control made it a target. Those limits later motivated my work on federated learning with tamper evident audit logging.
