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, and data pipelines, I bridge product vision with technical execution.

About Me

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

My work includes launching an AI-powered (Windsurf-integrated) dev assistant that sped up PR cycles by ~18%, cutting query latency by 40% in matching APIs, and driving >$120k/year cloud savings through OpenSearch ILM + shard tuning and gp3 migration.

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

When I’m not coding, I’m pursuing advanced certifications (CKAD, AWS Solutions Architect, AWS ML Specialty), exploring AI/ML integration into developer workflows, and spending time with my family in Texas.
