Employment
Experience
- Crunchhttps://github.com/vukicevic/crunch
Crunch is an arbitrary-precision integer arithmetic library for JavaScript. It has been designed to execute arithmetic operations as quickly as possible, in particular those upon which asymmetric encryption crypto-systems such as RSA are built.
- Verbatimhttps://verbatim.link
A pastebin website.
- IoT Platform
I designed and built an IoT platform for collecting sensor data and monitoring critical high-value lab instruments. I started as a contributor and quickly progressed to the team and project lead. While leading the project, we cut the operational costs of the platform by 75% as well as stabilizing the product, cutting the number of high priority incidents to single digits in the following year.
- Data Platform
I designed and built a data lake and data acquisition layer for collecting and storing files.
I led a team of engineers who have built a successful product gaining traction in the life-sciences and pharma industries.
