About Me
I am an engineer with 8+ years of combined experience in technical consulting, software development and solution implementation. My career has taken me to work in the EMEA, LATAM and NORAM regions for clients in various fields, such as manufacturing, control engineering, digital twins and analytics.
My interests lie in the junction between technology and applied mathematics, with a particular focus on using analytical techniques to make informed decisions on operational challenges. I also enjoy supplementing my skills with new tech stacks for building user-friendly and adaptable software solutions that deliver value.
Latest stacks I have been working with:- Java
- CentOS
- Docker
- Podman
- Python
- Pop!_OS
Experience
- Implementation of analytics solutions to a range of customers in banking and retail in the LAC region.
- Responsible for the full implementation cycle: configuration, data migration, development, testing

I worked as an Operational researcher in the CReDo project, a digital twin demonstrator that aims to improve climate resilience across infrastructure networks. Collaborated with Lars Schewe and Chris Dent from the University of Edinburgh, and Maksims Abalenkovs from the Hartree Center.
Project deliverables:
- Development of connectivity models of each network to assess impact and fault propagation.
- Development of a mathematical model for defining the best
restoration steps for bringing the most sites to operation. - Model deployment in Podman containers.
