What I'm looking for

I’m looking to lead engineering on secure, high-throughput fintech platforms—owning architecture and CI/CD, integrating cloud services, and using AI-assisted development to ship reliable products with measurable performance gains.

I’m a Software Engineer and technical lead for a full-stack API Explorer platform built for a payment provider, where I’ve owned architecture and CI/CD pipelines using AWS CodeBuild/CodePipeline and driven a feature roadmap. I transformed an unstable project into a secure, reliable platform and enhanced responsiveness by 60%.

I also led end-to-end delivery of two cloud ERP integrations (.NET, Kotlin) serving 500+ companies, and built event-driven fintech middleware in .NET for XML transaction export with DynamoDB, complex authorization flows, and end-to-end encryption. I strengthen reliability with AWS CloudWatch alerting and PostgreSQL tuning, deliver cross-platform clients like iOS, and integrate AI into my workflow with Claude Code, GitHub Copilot, LLM APIs (Claude, OpenAI), and MCP to optimize efficiency by 50%.
