[PROFESSIONAL SYNOPSIS]
From Systems Analyst to SaaS Architect: With over 5 years of deep full-stack experience, I bridge the gap between rapid prototyping and enterprise-grade stability. I have a proven track record of scaling systems, evolving from optimizing legacy databases to architecting complete cloud-native platforms from the ground up.
I am a specialist in the Laravel Ecosystem, known for engineering high-performance APIs and integrating third-party applications.
Currently, I am deepening my DevOps and Kubernetes expertise to build self-healing, scalable infrastructures. I am passionate about writing clean, maintainable code that doesn't just pass tests, but solves high-stakes business problems.
[Key Performance Milestones]
- Cost Optimization: Achieved a 60% cost reduction for a platform that had high and low peaks of access throughtout the day and relied on manually scaling resources. I've upgraded Laravel for 3 different platforms in their ecosystem, dockerized them and them deploy on kubernetes to auto-scale when required.
- Performance Optimization: Achieved an extraordinary score in metrics platforms such as PageSpeedInsights by following best practices of optimization for content delivery while refactoring many Javascript and SCSS/CSS files.
