[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.
[FEATURED PROJECTS]
Selected solutions demonstrating full-stack expertise and system architecture.
01 // SaaS Raffle Platform
PRODUCTIONHigh-concurrency raffle system processing 5,000+ transactions/min with real-time WebSocket updates. Engineered for 20,000+ concurrent users with zero data loss during peak loads.
02 // Service Order ERP
PRODUCTION
A modern service order ERP built with Laravel and Filament. It allows to manage service orders, customers, products, and more. I also aim to integrate it with third-party applications like N8N and webhooks to automate the workflow.
Users may plan their service orders, assign technicians, and track the progress of the work and payments. It will be possible to upload pictures and generate payments thus optimizing the worker's time.
03 // AI-Driven Legacy Modernization
R&DAn intelligent static analysis and refactoring engine designed to bridge legacy codebases with modern AI. Automates recursive codebase audits, calculating real-time Tech Debt Ratios and Cyclomatic Complexity to pinpoint architectural decay and suggest precise, AI-powered refactorings.
