As a FullStack and DevOps Engineer, I successfully led the end-to-end industrialization of machine learning workflows by automating model lifecycle management and deployment. • Designed and implemented an MLOps pipeline using Apache Airflow, orchestrating data ingestion, preprocessing, model training with XGBoost, and validation, reducing processing cycles by 25%. • Integrated DVC and MLflow for dataset/model versioning and experiment tracking on DagsHub, with automated validation using Deepchecks. • Automated the deployment of an ML API with FastAPI, Docker, and Kubernetes, integrating joblib models with Prometheus/Grafana for monitoring. • Configured a Jenkins CI/CD pipeline to deploy React, Spring Boot, and FastAPI applications on Kubernetes through NGINX Ingress, ensuring reliable and scalable delivery.

As a DevOps Engineer, I successfully led a project to improve an existing infrastructure by implementing various automation solutions. • Established robust CI/CD workflows utilizing Azure DevOps; facilitated more efficient deployments that decreased average downtime by 35%. • Orchestrated robust cloud architecture utilizing Azure Kubernetes Service alongside Docker containers for application deployment. • Automated infrastructure provisioning using Terraform on Azure, ensuring scalability and security best practices. • Performed static code analysis using OWASP in the development pipeline, ensuring continuous code quality. • Established real-time monitoring with Prometheus and Grafana, enhancing metric visualization and enabling rapid identification of performance bottlenecks, resulting in a 30% reduction in downtime incidents.

As an IT Technician, I successfully enhanced the operational efficiency of our IT infrastructure through various technical solutions • Installing and configuring hardware and software to ensure optimal performance and reliability across systems. • Maintaining and troubleshooting existing IT equipment to minimize downtime and ensure smooth operations. • Configuring and managing the agency's mailing server to ensure secure and efficient email communication. • Conducting regular system backups to ensure data integrity and availability in case of failures. • Implementing security protocols to protect sensitive data and ensure compliance with industry standards.

As a Back-End Developer, I played a crucial role in creating an online check tracking platform from concept to deployment. This included: • Developed an online check tracking platform using Symfony and PHP, handling the management of check statuses (pending, cleared, bounced). • Implemented secure authentication and authorization protocols using Symfony’s built-in SecurityBundle for role-based access control and JWT (JSON Web Tokens) for secure token-based authentication. • Integrated a relational database (MySQL) using Doctrine ORM for efficient data management and implemented prepared statements to prevent SQL injection. • Deployed the platform on shared hosting using CWP (CentOS Web Panel), configuring firewalls, SSL certificates, and backup solutions to enhance security and ensure high availability.

• Developed responsive web page layouts using HTML5, ensuring semantic structure and proper use of tags for improved SEO and accessibility. • Styled web pages with CSS, implementing design principles and best practices to create visually appealing interfaces, including typography, color schemes, and spacing. • Implemented dynamic user interactions using JavaScript, creating features such as image sliders, tabbed navigation, and form validation to enhance user experience. • Integrated third-party APIs using JavaScript, fetching and displaying real-time data on web pages, and ensuring proper handling of asynchronous requests. • Participated in version control with Git, managing code repositories and collaborating with team members through pull requests and code reviews. • Documented code and project components, creating clear documentation for functionality, setup instructions, and user guides to assist future developers.
