Corey R.

I build AI agents, RAG systems, web apps, and API automations with Python, React, Next.js, and TypeScript. My work includes Synapse's pgvector retrieval system and Procore/Microsoft 365 integrations.

I'm Corey, a senior full-stack developer with 15+ years of experience and the founder of Rosecraft Studios. I build practical software around a defined workflow, with clear acceptance criteria and a documented handoff.

AI AGENTS, RAG AND LLM INTEGRATION
I built Synapse, an internal knowledge-retrieval and agent-memory system using TypeScript, Node.js, PostgreSQL and pgvector. It combines document ingestion, embeddings, vector and keyword search, source references, tenant-scoped retrieval, and MCP access. My Cortex work covers LLM provider integration, tool calling, approval controls, run history and usage tracking. I also built a Next.js/OpenAI web application with streaming responses and multi-turn conversations.

PYTHON, APIs AND WORKFLOW AUTOMATION
REST and SOAP API integration, FastAPI webhooks, data synchronization, scheduled jobs, CSV processing and validation. My Procore/Microsoft 365 work connected construction data with SharePoint, reporting and file routing. Related Python work includes signed webhook processing and a spreadsheet/text-PDF parser that checks line arithmetic and totals, records source references, and flags ambiguous input.

WEB SCRAPING AND DATA PIPELINES
Python, Selenium, requests and pandas for extracting data from static and JavaScript-rendered sites, normalizing records, deduplicating across sources, and exporting usable CSV files. I have also built a Tebra SOAP-to-Azure SQL pipeline supporting Power BI patient reporting.

FULL-STACK WEB APPLICATIONS
React and Next.js interfaces, Node.js, Python and PHP backends, authentication, dashboards, internal tools, portals and database integration. My work includes React/Node.js maintenance and integration contributions to GiveTrack, plus Python/PostgreSQL modernization, compatibility fixes and structured logging.

MOBILE AND MEDIA AUTOMATION
React Native/Supabase development, including authentication, assessment flows, results and subscription screens. I developed a leadership assessment app through TestFlight delivery preparation. I also built a Python/FFmpeg pipeline that turns CSV inputs and supplied assets into personalized MP4 videos.
