I'm a Senior Full-Stack Software Engineer and Cloud Infrastructure Architect with 15+ years building web applications, APIs, and enterprise cloud platforms. I take ownership of complex technical challenges from concept to production and thrive on delivering high-quality solutions that scale across multi-region architectures and mission-critical workloads. On the backend, I work with PHP (Laravel, Symfony, Zend), Python, Django, Node.js, and Java/Spring, building REST APIs, GraphQL endpoints, and microservice architectures. My frontend expertise includes Vue.js, React, Angular, JavaScript, TypeScript, HTML5, and CSS3 with responsive design principles. My AWS and cloud expertise spans ECS, EKS, Lambda, API Gateway, DynamoDB, RDS, ElastiCache Redis, EFS, KMS, Route 53, CodeDeploy Blue/Green deployments, WAFv2, CloudWatch, S3, EC2, and SQS, with experience in architecting multi-region active-active systems. I build infrastructure as code using Terraform and CloudFormation, containerize applications with Docker and Kubernetes, and implement CI/CD pipelines using GitHub Actions, Bitbucket Pipelines, and AWS CodePipeline. My security toolchain includes tfsec, Checkov, Trivy for container scanning, Syft for SBOM generation, and Cosign for image signing. For data persistence, I work across MySQL, PostgreSQL, MongoDB, DynamoDB, and Redis, with expertise in schema design, query optimization, cross-region replication, and caching strategies. I'm passionate about test-driven development (PHPUnit, Jest), infrastructure as code, and mentoring engineers to embrace engineering best practices. I practice Agile/Scrum methodologies and believe in code reviews, pair programming, and cross-functional collaboration. My work includes architecting SOC 2 Type II, ISO 27001, and PCI DSS compliant systems, leading chaos engineering initiatives, and building global payment integrations.
