Designed, built, and deployed full-stack web applications using React, Node.js, and PostgreSQL, improving scalability, user experience, and reducing reported issues. Automated microservices deployment with Docker and Docker Compose, while leveraging Ansible for configuration management (playbooks, roles, provisioning of services/VMs) and Terraform for infrastructure as code, enabling reproducible, cloud-native environments. Provisioned and orchestrated multicloud infrastructure using Terraform across Microsoft Azure, AWS, and Google Cloud, including virtual networks, load balancers, and compute resources, ensuring scalability, cost-efficiency, and compliance with IaC best practices. Implemented CI/CD pipelines with GitHub Actions, integrating automated testing (unit/integration), security scanning with OWASP ZAP, Trivy, Snyk, SonarQube, Ansible Vault, dependency checks, and vulnerability assessments, accelerating secure and reliable software delivery. Monitored system health with Prometheus and Grafana, improving uptime, reducing MTTR (Mean Time to Recovery), and enabling proactive incident management. Enhanced DevOps collaboration by integrating custom Discord webhooks to deliver real-time build status (success/failure), security test artifacts, and dynamic VM details (name, external IP).

Built a secure real-time chat application using Flutter (frontend) and Spring Boot (backend), ensuring a responsive and reliable user experience. Improved data security by 25% through securing API communications, user sessions, and implementing best practices for authentication. Optimized backend performance, reducing latency and enabling smoother real-time interactions. Managed MongoDB database schema for user authentication and chat storage, ensuring scalability and data integrity.

Developed scalable web applications using Vue.js (frontend) and NestJS (backend), containerized with Docker for reliable deployment. Built enterprise CRUD features and optimized workflows, improving efficiency for business clients. Delivered reusable, responsive UI components, enhancing usability and user experience across devices.

Led full-stack development of a web and mobile Covid-19 response application, improving access to critical health resources. Designed a real-time geolocation service to track available oxygen devices, enhancing timely patient support. Built a contact platform connecting users with health services, facilitating faster assistance and better resource allocation. Developed an administrative dashboard for monitoring and managing healthcare resources efficiently.

Designed an intuitive frontend for reporting public infrastructure issues (e.g., streetlight outages), making it easy for users to report problems quickly. Created a dashboard aggregating incident reports with real-time geolocation data, improving monitoring and response efficiency for city services.
