Leading the design & development of a unique approach to automated trading to democratize investing.
Developed from scratch a complex IAS (Intelligent Agent System) supporting running thousands of
agents per user, using OOD, OOP, TDD, BDD, and design patterns like dependency injection, facade,
observer. Architected and implemented an IaaS (Infrastructure-As-a-Service) system with focus on
security and performance, by combining GCP services, virtualization and custom-made proprietary
technology. Created a framework for dynamic UI generation by combining advanced meta-
programming in Python3, VueJS3 and vanilla JS. Developed a CLI tooling for orchestrating and
automating the deployment of the whole microservice infrastructure with the click of a button, based
on Terraform, Pulumi, Ansible, Snyk and other DevOps and SecOps tools.
