Jaelyn Cuellar

• Owned full-stack development of a healthcare data platform: designed the PostgreSQL schema, built the Express REST API with JWT/bcrypt authentication, and shipped the React frontend consuming it.
• Improved reliability across the stack with centralized error handling, request schema validation, and secure authentication flows.
• Translated business requirements into technical solutions through iterative Agile delivery.

• Built and deployed a cloud-hosted Next.js + TypeScript application, owning features end-to-end from API routes and database to UI.
• Designed backend workflows for booking and notification systems and the frontend surfaces that drive them, emphasizing maintainable architecture.
• Set up secure routing, automated backups, Git/GitHub CI workflows, and production monitoring; gathered requirements directly from stakeholders.

• Developed cloud-based analytics solutions on live AWS and Azure pricing data; built data ingestion pipelines and backend services for real-time cost analysis.
• Implemented secure IAM policies and API integrations; delivered features through Agile sprints with design discussions and code reviews.

ASP.NET Core, C#, PostgreSQL, Redis, JWT

• Cut API response latency ~40% under concurrent workloads with Redis caching; optimized database access and async processing for peak-traffic throughput.
• Applied design patterns and JWT-based authentication for maintainable, fault-tolerant services.

Python, BERTopic, Transformers, NLP

• Processed 23,000+ text records with transformer embeddings and BERTopic, automating theme extraction and eliminating manual labeling.
• Built modular ML pipelines that reduced experimentation time by ~50%.

• Supported 100+ students weekly across lab sessions through hands-on code review and debugging.

• Drove 6 concurrent Agile engineering teams to delivery of production web and data applications with zero missed sprint milestones.
