I'm Leah R. Tucker

I architect the platforms and write the playbooks that empower developers to build and deploy next-generation AI products.

About Me

Tech puzzles? They're my kind of fun.

I pick up new systems fast, build the missing pieces end-to-end, and leave documentation that doesn’t punish the next person.
 
Started in college by reading other people’s HTML source. Still haven’t stopped.
 
Stripe, AWS, Sabre, Avis, Blinkt AI — the production RAG system I built because the prototypes I kept seeing all failed in the same places.
 
Things end up simpler afterward. That’s the quiet part I’m chasing every time.

Tech Stack

AI & MLOps Lifecycle

  • Multi-stage RAG pipelines with HyDE, hybrid search, cross-encoder reranking
  • Automated fine-tuning loops (PyTorch, Sentence-Transformers, Celery, Redis)
  • Real-time knowledge graph construction for causal and temporal reasoning

Cloud & Infrastructure

  • Docker, multi-stage builds, custom runtime images
  • Kubernetes, Amazon EKS (stateful and stateless workloads), GPU node pools
  • EC2, Fargate, S3, IAM, CloudWatch, Secrets Manager

Application Development

  • Python (FastAPI, Flask), JavaScript
  • PostgreSQL, Redis (caching, queues, session store)
  • WebSockets, Server-Sent Events

Professional Highlights

Stripe

Learned all seven Stripe SDK languages → shipped developer Quickstarts → contributed to a 25% lift in Checkout activation. 

AWS

First time using Kubernetes → deployed a full bookstore app on EKS → wrote the developer workshop.

Sabre

Led API developer portal migration from concept to launch for 2,500+ API products, delivering RBAC, live-call functionality with OpenAPI (Swagger), automated test suites.

Avis Budget Group (ABG)

Led the ground-up API design for ABG’s $1.25 billion launch by creating reusable data models in 36 hours, resulting in a 75% reduction in deployment time.
