Senior backend engineer building agentic AI tooling and cloud CI/CD systems.

Message

I’m a Senior Backend Engineer specializing in AI-assisted development, agentic workflows, and cloud-native CI/CD systems. I build autonomous AI tooling that connects directly to real engineering workflows—Git, Jira, Snyk, and AWS CLI—so teams can ship faster and safer.

At Travelers Insurance, I architected and delivered 5 cloud-native backend services and APIs with C# and AWS, supporting enterprise-scale integrations. I reduced team sprint delivery time by 2–3 days per cycle by introducing Claude Code and GitHub Copilot, and I cut manual testing effort by ~40% through AI-assisted test generation.

I streamlined deployment frequency by streamlining CI/CD pipelines with Terraform and Jenkins, and I migrated legacy .NET Framework apps to .NET Core and .NET 8 to improve performance and maintainability. I’ve also built event-driven architectures using Lambda, Step Functions, and DynamoDB, and I implemented centralized observability with ElasticSearch and CloudWatch to speed up incident detection and resolution.

Beyond day-to-day engineering, I engineered a custom Claude Code skill and autonomous agent that polls Git for assigned pull requests, runs Snyk security scans locally, and evaluates code against Jira acceptance criteria and architectural standards—predating the enterprise-wide AI code review tool later adopted by Travelers.
