Vlad Onetiu

• Designed, implemented and evaluated new models and rapid software prototypes to solve problems in machine learning and systems engineering.
• Developed custom machine learning algorithms for specific industry needs, resulting in improved performance and efficiency.
• Worked closely with domain experts to ensure accurate representation of problem context within developed models, enhancing their real-world applicability.
• Transformed raw data to conform to assumptions of machine learning algorithm.
• Developed Machine Leaning infrastructures in Azure, GCP, AWS and data pipelines for training different models using Kubernetes and Serverless functions
• Assured the entire infrastructure of the best Security Engineering best practices
• Created complex architectures, designs for data pipelines and models operations

- Deploy cloud infrastructure, infrastructure as code on AWS/Azure with Terraform and Ansible for configurations
- Continuous Integration and Continuous Delivery (CI/CD - Jenkins/Bitbucket Actions)

- Build client's environments(test, acc, production) from scratch in VPC architecture, and deployed the application and the microservices with multiple Docker containers which communicated with each other to create the app ecosystem
- Cloud architecture design
- DevSecOps (SSL certificates for WEB and for the FIX connection, accountability for DAST and on the findings)
- Conducted large scale operations and provided guidance for the rest of the project team in the most critical situations
- Assumed critical operations decisions for releases/deployments

- Guided team members in their tasks

- Worked on behalf of the project for the biggest banks in Europe and had direct contact with the stakeholders within those banks

- Had direct alignments with the stakeholders of the project for the technical problems/improvements of the project and acted also as Team Leader/PO for DevSecOps & Software Automation areas in multiple ocassions

- designed the job interviews plan and interviewed candidates for DevOps & Software Automation positions

- Monitoring tools: Zabbix, Wazuh, Grafana, Opensearch

Jenkins jobs using slaves through AWS – Auto Scaling with Launch Configurations/Launch Templates

•Implementation of an automated structure of testing from scratch based on Protractor framework, integrated with an Angular + Spring Boot financial application
•Building the entire testing architecture from stage 0 to a stable solution which was executed in a automated way on every production version;
•The Angular testing concept was based mainly on OOP paradigm, through Typescript & JavaScript. Using page objects to separate the test specs from the framework backend part.
•Built the entire deployment testing pipeline using virtualisation focused on Docker containers, and orchestrate it by Jenkins shell scripts
•Built the solution for performance automated testing of the application's APIs. Every endpoint was treated in isolation and was measured to see if there are some performance leaks. Here were used tools like JMeter and Taurus framework on top, and embed all in a Jenkins deployment job through scripts
•Analysed and validated the security of the Spring Boot application API's in terms of field validation, business segregation of roles, error handling on different request injection approaches. Proposed new solutions where there were possible security vulnerabilities
•Analysis of the authentication part through an IAM solution, based on Keycloak. Improving the authentication flow within the application on the technical side that involves the generation of access tokens, their persistence and their business interpretation through the application.
•Conducted data migration tasks in code written in Java.

•Designing and creating integrations in the ERP module to work for different finance clients and discussing them directly with the stakeholders and clients

Working part time for an intern project and for the license thesis:

Modelation, and real time simulation of a DC Motor with LabVIEW; Built from the mathematical equations to a virtual modelation a Proportional Integral controller,to control the speed of the motor;

•Testing of the DC Motor through real time sequences, using Stimulus ProfileEditor;
