Senior Full Stack Engineer | AI Platform | Frontend Architect

I design and build scalable, data-driven applications and modern web platforms that deliver measurable business impact. With 16+ years of experience across full-stack engineering, cloud infrastructure, distributed data systems, and AI-assisted development workflows, I bridge product vision with pragmatic technical execution. My work spans large-scale analytics platforms, search infrastructure, frontend architecture, and applied AI reliability, with contributions to industry publications, peer review, and engineering research.

About Me

I am a Senior Full-Stack & AI Platform Engineer with 16+ years of experience designing search platforms, distributed data pipelines, and modern frontend architecture. At Wiser Solutions, I lead initiatives in product matching systems (React + GraphQL + NestJS), real-time analytics platforms (dbt + Trino + Apache Iceberg), and Elasticsearch/OpenSearch scaling, relevance tuning, and cost optimization.

My work includes building AI-assisted developer workflows using Windsurf and Claude Code that improved PR turnaround time by ~18%, reducing query latency in matching APIs by 40%, and driving more than $120k/year in cloud savings through Elasticsearch/OpenSearch ILM strategy, shard optimization, and gp3 migration initiatives.

Beyond delivery, I focus on scalability, reliability, performance optimization, and developer productivity—turning complex systems into maintainable engineering platforms.

When I’m not coding, I’m pursuing advanced certifications including CKAD, AWS Solutions Architect, and AWS ML Specialty, exploring applied AI/ML systems, and spending time with my family in Texas.
