What I'm looking for

I’m looking for a role where I can build scalable SaaS products with modern React/Node, own architecture, and strengthen reliability through CI/CD, monitoring, and security—working in a team that values engineering excellence and measurable outcomes.

I’m a Full Stack Developer who builds highly responsive, interactive web applications with test-driven development, aiming for measurable quality like 100% code coverage. I design reusable UI libraries (React & Vue) from Figma mockups and deliver end-to-end features using React/Nextjs/Vue and robust Nodejs backends.

Across my roles, I’ve architected SAAS platforms with microservices and event-driven design, integrating services with Azure DevOps and Stripe while automating production deployments on AWS. I also lead reliability and growth initiatives—automating migrations of 80+ sites, setting up CI/CD and monitoring for large fleets, and strengthening security with access controls and AWS WAF/CloudFront.
