What I'm looking for

I seek senior engineering roles building scalable, secure cloud-native web platforms where I can lead architecture, mentor teams, and improve delivery velocity.

I am a Senior Full Stack Engineer with a decade of experience architecting, developing, and scaling enterprise-grade web platforms using TypeScript, React, Next.js, Node.js, and NestJS. I specialize in transforming monoliths into modular, cloud-native microservices, building resilient distributed systems, and delivering real-time dashboards with sub-second latency.

My work includes designing GraphQL federations and subscription architectures, engineering partitioned PostgreSQL stores, and integrating CI/CD pipelines with Terraform, Kubernetes, and AWS to enable zero-downtime deployments. I enforce security-first principles—AES256, TLS 1.3, OAuth2/JWT—and have delivered compliance-ready solutions (SOC2, CJIS) for sensitive domains.

I mentor engineering teams, establish component-driven design systems, and bridge ecosystems with complementary Golang and Ruby experience. My pragmatic combination of hands-on engineering, architectural foresight, and leadership drives measurable improvements in performance, reliability, and developer velocity.
