About me
Intro
I’m a technology enthusiast with over 9 years of software development experience and 5+ years guiding technical teams through Agile frameworks like Scrum. I thrive at the intersection of innovation, leadership, and people, blending my technical expertise with a keen understanding of human dynamics—thanks to my studies in philosophy and psychology. Certified as a Professional Scrum Master (PSM I®), Product Owner (PSPO I®) by Scrum.org, and AWS Solutions Architect (SAA-C02®) by AWS, I’ve led diverse teams in building scalable solutions using tools like Lambda, Terraform, Python, Node.js, Java, Angular, and more. My experience spans roles as a Product Owner for mobile apps in retail, Scrum Master for IoT cloud applications, and mentor for a programming bootcamp. I’ve collaborated closely with Software, DevOps, QA, Security, and Architecture teams to deliver impactful products. Leadership to me is about fostering stable, flexible teams—prioritizing people over processes while driving value through data-driven insights (KPIs, velocity dashboards, UATs) and tools like JIRA. My technical foundation includes cloud architectures (AWS, Azure), serverless systems, CI/CD pipelines, and infrastructure-as-code (Terraform, CloudFormation), complemented by hands-on coding in modern stacks. Beyond tech, I’ve published research on algorithms’ influence on human relationships, reflecting my curiosity about how technology shapes our world. I bring empathy, adaptability, and a people-first mindset to every challenge—whether it’s solving abstract problems, mentoring teams, or architecting solutions. Experience in IT leadership: • Advanced use of JIRA for project tracking, dashboards, statistics, releases, and support. • Scrum lead and mentor, using Scrum and Agile to aid team workflows. • Led teams with a people focus, fostering collaboration and value. • Worked with devs, architects, UX, and stakeholders to align projects. • Tracked progress with velocity, burndown charts, and metrics. • Backed product value with KPIs, UAT, and 1:1s. • Provided technical context for assessing technical decisions Experience in technology: • Cloud (Amazon Web Services, Azure) & Serverless (Lambda, Python, Node.js) • Infrastructure (Terraform, Ansible, InSpec, OpenStack, Shell, Groovy, Ruby) • CICD/Monitoring (Jenkins, SonarQube, CloudWatch, Elastic) • Monolith apps (Java WS, PHP, Spring Boot Hibernate) • Databases (DynamoDB, MySQL, PostgreSQL, MongoDB) • Web and Frontend (Javascript, Angular, Ionic) • Hybrid Mobile (Ionic, Ionic2, Cordova, etc.)
