Hire Tyler M. - Forward Deployed Engineer

* An open-source, self-managed platform that evaluates chunking strategies and deploys ETL pipelines for RAG systems. * Built a microservice-based backend using FastAPI, separating concerns across chunking, evaluation, and orchestration services, with standardized APIs and shared Pydantic models for type-safe inter-service communication. * Created a uniform abstraction layer over multiple third-party chunking libraries (LangChain and Chonkie), normalizing metadata to enable consistent visualization, evaluation, and cross-provider comparison. * Architected a scalable ETL ingestion pipeline using AWS Batch on Fargate to parallelize document chunking and embedding generation, balancing throughput with external API rate limits. * Developed a real-time job tracking system using Server-Sent Events (SSE) to stream progress from AWS Batch document processing jobs to the client UI. * Deployed a data persistence layer using Amazon S3 for document storage and Amazon RDS PostgreSQL (with pgvector) for embedding storage, separating experimentation and production workloads for isolation and scalability. * Implemented a retrieval-based evaluation service that computes Precision, Recall, and Intersection over Union (IoU) * metrics to quantify the semantic coherence of chunking strategies against LLM-generated ground truth. * Built a document normalization system to sanitize multi-byte Unicode artifacts, eliminating tokenization failures in downstream embedding models and ensuring consistent evaluation accuracy.

* Request Bin: A developer tool for receiving, persisting, and inspecting HTTP requests and webhooks via a generated URL endpoint (JavaScript, Express, MongoDB, PostgreSQL, WebSockets, AWS, Nginx) * Job Hunt Assistant: A RAG application with chat history and token management (Python, PostgreSQL, RAG) * Shopping Cart: An e-commerce shopping cart app (TypeScript, React, Express, MongoDB)
