Hi, I'm Calogero Di Mino πŸ‘‹

Technical Business Analyst & PM | DevOps Expert | Digital Transformation Leader


πŸš€ About Me

I'm a DevOps-oriented Technical Business Analyst with 7+ years of experience driving digital transformation across FinTech, cloud, and platform integration domains. My expertise bridges development, QA, and operations, with a strong focus on automation, scalability, and secure systems.

πŸ”Ή I've led end-to-end API integrations (RESTful / JSON), CI/CD pipeline design (Jenkins, GitHub Actions, GitLab CI), and Infrastructure-as-Code with Terraform & Ansible.

πŸ”Ή Skilled in troubleshooting complex production issues, managing system configurations, and debugging using tools like Postman, ELK Stack, and Putty/SSH.

πŸ”Ή Delivered enterprise migrations (e.g., FIS CMS from C++ to Java), ISO-compliant API transformations, and 3DS SDK configurations across banking platforms.

πŸ”Ή Passionate about cloud (AWS, GCP), observability, and collaborative DevOps culture β€” with hands-on experience in BDD, API testing (Rest Assured, Selenium), and stakeholder engagement.

πŸ”Ή Successfully managed a large-scale migration from GitLab CI to GitHub Actions, creating structured migration plans, automating daily progress reports, and mitigating risks across multiple repositories.

πŸ”Ή I love building efficient, automated solutions that empower cross-functional teams and improve service delivery at scale.

πŸ† Key Achievements

πŸš€ Led end-to-end technical integrations for global clients in FinTech, including full API lifecycle delivery (design, documentation, testing, training), improving time-to-deploy by 60%.

πŸ› οΈ Engineered CI/CD pipelines with Jenkins, GitHub Actions, and GitLab CI/CD, reducing release friction and accelerating deployments across development stages.

☁️ Designed multi-cloud automation strategies leveraging Terraform, Ansible, and Docker, ensuring scalable and consistent infrastructure deployments.

πŸ“Š Built real-time dashboards using ELK stack (Kibana, Logstash) for production insights, enhancing observability and reducing MTTR by 45%.

πŸ” Pioneered API standardization initiatives, migrating legacy systems to RESTful APIs with OpenAPI/Swagger specs aligned with ISO naming conventions.

πŸ“¦ Directed critical data migration projects, including FIS CMS from C++ to Java, managing HAProxy changes and configuration alignment for high availability.

πŸ”„ Automated testing frameworks (BDD with Rest-Assured, Selenium) to ensure quality assurance pipelines remained efficient and traceable.

πŸ“š Delivered cross-functional training workshops (UI/UX, APIs, system integrations) for clients and internal teams, bridging business and technical understanding.

🧠 Served as Dev–Prod bridge, owning non-prod environments, supporting client-facing teams, and enhancing operational readiness through root cause training.

πŸ” Supported 3DS Modirum SDK integration, providing secure configuration, BDD testing, and mapping edge cases for strong customer authentication.

πŸ’‘ Created infrastructure and monitoring workflows using GitOps practices, integrating with tools like ServiceNow, Guardicore, and APM platforms.

🧩 Facilitated Agile transformation, aligning business analysis, QA, and DevOps with Scrum/SAFe methodologies and driving continuous delivery culture.
