Developed and maintained live-service gaming systems, backend services, and internal tools using .NET, AngularJS, Redis, DynamoDB, Memcached, MySQL, S3, and Unity. Designed and maintained a web-based customer support platform that enabled support teams to resolve player issues independently, reducing engineering involvement in day-to-day operations. Supported infrastructure and backend systems serving 60K+ daily active users while maintaining scalability, reliability, and operational efficiency. Reduced AWS infrastructure costs by 50% through EC2 provisioning optimizations, Auto Scaling configuration improvements, load balancer right-sizing during low-traffic periods, and DynamoDB usage optimization. Optimized Redis cluster key architecture, reducing memory usage by 85% and improving infrastructure efficiency. Optimized high-traffic APIs, maintaining sub-300ms response times across 80% of endpoints. Led migration from internally built analytics and A/B testing systems to scalable third-party platforms, reducing maintenance overhead. Improved platform security by implementing AWS Secrets Manager for credential management, Parameter Store for configuration management, IAM-based access controls, VPC-based database isolation, and anti-replay protections for critical API endpoints.

Collaborated with distributed teams across Guatemala and the United States to maintain and optimize enterprise platform architecture. Developed scalable microservices and monolithic applications using modern Angular and .NET technologies. Designed and maintained CI/CD pipelines automating deployments, testing, and database migrations across multiple environments. Implemented Linux server hardening and infrastructure security improvements following DevOps best practices. Supported production deployments and application reliability across test and production environments. Utilized Infrastructure as Code practices with Terraform to provision and manage cloud resources.
