Resume

Seasoned IT professional with 20 years of diverse experience across software development, DevOps, and cloud infrastructure—specializing in cloud architecture and strategic team leadership. Currently serving as a Technical Architect and Senior Cloud DevOps Engineer, I focus on leveraging AWS serverless technologies and microservices architecture to deliver scalable, high-performance, secure solutions. Over the past 13 years, I've developed deep expertise in backend development using Java and Spring, complemented by strong proficiency in relational databases. My technical toolkit includes Java, TypeScript, Python, and Terraform for infrastructure as code—enabling our teams to build innovative systems that drive operational efficiency and security. With hands-on experience across a broad spectrum of AWS services— including Lambda, CloudFormation, AppSync, WAF, IAM, Step Functions, API Gateway, Cognito, EC2, Auto Scaling Groups, Load Balancers, DynamoDB, S3, SQS, SNS, SES, CloudWatch, EventBridge, SSM, Secrets Manager, and CloudFront—I’ve architected and deployed both large-scale and small-scale applications from the ground up, including complex data migrations. As an integration lead, I’ve successfully guided teams, fostering a collaborative and high-performance culture to meet ambitious project goals. My leadership has been recognized through promotions across three distinct organizations.
