What I'm looking for

I'm looking to build reliable AI systems, evaluation tools, and data-intensive products where I can combine backend engineering, model validation, technical research, and structured quality-focused workflows.

At Nexus AI, I design and deploy scalable backend systems for AI model evaluation workflows and distributed processing. I build RESTful APIs and full-stack applications with Python, FastAPI, Next.js, PostgreSQL, and Redis.

I improve API response performance and backend throughput for real-time AI systems while evaluating model outputs, optimizing prompts, and strengthening model reliability.

Across Outlier AI and Scale AI, I've built dashboards, evaluation tools, backend services, and processing pipelines for grading, annotation, training, and large-scale AI data systems. My work combines technical reasoning, debugging, structured analysis, and careful validation.

At IBM, I developed production NLP and machine learning applications, model-serving APIs, and real-time processing services. I also build SaaS and iOS products, with a focus on responsive workflows, reliable data handling, and high-quality user experiences.
