What I'm looking for

I seek a senior engineering role owning frontend-focused web platforms with cloud-native infrastructure, strong CI/CD, observability, and opportunities to integrate AI/ML into product experiences.

I am a Senior Full Stack Web Developer with 8+ years building user-focused web applications and scalable backend services. I specialize in frontend-leaning (60/40) architectures using React, Angular, TypeScript, Java/Spring Boot, and Node.js.

I have led cloud-native modernization efforts, including migrating mainframe systems to Azure microservices, designing API contracts and authentication, and deploying via CI/CD to Kubernetes. My work emphasizes performance, observability, and production support for mission-critical systems.

Recently I have integrated AI/ML capabilities into web platforms—building LLM-powered document analysis, semantic search, RAG pipelines with vector embeddings, and workflow automation to improve relevance and user outcomes. I focus on end-to-end ownership from UI architecture and API design to testing and monitoring.

I bring a pragmatic engineering ethos: shipping accessible, high-performance interfaces, optimizing backend services, and automating delivery and observability. I hold a Master’s in Computer Science and enjoy solving complex problems that improve reliability and user experience.
