What I'm looking for

I’m looking for a team where I can architect cloud-native microservices and serverless systems, own infrastructure-as-code, and improve reliability and speed through automation, CI/CD, and event-driven design.

I’m a Senior Software Engineer with 13+ years building scalable systems in high-growth environments across startup and enterprise teams. I specialize in cloud-native development, infrastructure-as-code, and delivering production-ready applications that reduce operational friction.

In my recent role at Hexagon AB, I architected microservices-based solutions using Node.js and AWS Lambda, improving scalability by ~45% and enabling near real-time processing for high-volume data streams. I automated operational workflows with event-driven architecture, reducing manual intervention by nearly 50%, and enhanced user-facing performance by reducing response latency by 35%.

Earlier at Cargo Express Freight Corp, I designed serverless back-office automation and implemented GraphQL/REST integrations that cut data latency by 35% while improving delivery efficiency by ~42%. I also strengthened delivery reliability through CI/CD enhancements (GitHub Actions, Docker) and used Terraform to standardize cloud deployments, reducing provisioning time by 55%.

Across DoorDash and Globant, I’ve continued to focus on high-throughput systems, API development, and pragmatic engineering practices—optimizing pipelines for throughput by ~37% and improving time-to-market through faster feature delivery. I lead Agile teams, mentor engineers on microservices and cloud-native development, and apply automation and test-driven development to consistently raise quality.
