What I'm looking for

I’m looking to build reliable, high-performance products with a strong backend foundation (Laravel/PHP) and practical AI-assisted delivery, working in agile cross-functional teams with AWS-powered architectures and clear ownership from MVP to production.

I’m a Full Stack Software Engineer with over 7 years of experience building and scaling web and mobile applications. I focus on backend strength in Laravel and PHP, while delivering strong frontend and mobile experiences with Angular, React, React Native, and Ionic.

In my recent roles, I’ve modernized and hardened production systems—upgrading a Laravel 8/PHP 7.4 codebase to Laravel 13/PHP 8.5, designing AI-assisted features like automated site import workflows, and creating an automated test pipeline that increased test coverage from 0.5% to 60% (and still growing). I also improve development quality through static analysis by configuring PHPStan.

I bring end-to-end delivery and cloud ownership, having built and operated platforms on AWS (including EC2, Lambda, API Gateway, SQS, RDS, DynamoDB) with CI/CD using CodePipeline and CodeBuild. I’ve also led cross-functional teams, published multiple mobile apps from scratch, migrated Ionic apps from Cordova to Capacitor, automated API documentation with OpenAPI and Docusaurus, and driven performance improvements that enabled a 2,666% traffic surge without service degradation.
