What I'm looking for

I’m looking to lead full lifecycle delivery as a Full Stack/Team Lead—modernizing legacy systems, building resilient cloud infrastructure, and owning high-scale backend and DevOps responsibilities with a focus on reliability and cost control.

I’m a Full Stack Developer and Team Lead focused on building and maintaining web applications and the infrastructure behind them. I manage the full lifecycle of software projects—from writing code and setting up servers to leading development teams that refactor legacy systems.

Most recently, I’ve been designing legacy code refactors and making decisions to port legacy jQuery to React, while planning next steps for modernization. Previously, I led Terraform-driven infrastructure for scalable AWS environments, handling 250k+ applications and designing backend services.

I’ve also delivered high-impact platform work across backend, DevOps, and cloud migration—porting GCP to AWS for systems with 500k monthly receipts and 700+ monthly active users, and implementing disaster recovery and resilience improvements after production incidents. I bring an ownership mindset that prioritizes reliability, cost control, and scalable architectures.
