At Medallo.dev, I build and maintain the services behind a multi-stage candidate pipeline, connecting intake, screening, scheduling, e-signature, and hiring through real events. I also develop MCP servers that let non-technical colleagues run production workflows in natural language.
When a vendor webhook proved unreliable, I replaced it with scheduled polling to restore delivery. I added an event ledger, job heartbeats, webhook error capture, and a health-check endpoint so pipeline failures produce actionable signals.
At Pocket Friend, I built an AI-powered personal finance tracker with an agent assistant, responsive dashboards, and LangGraph workflows for transaction classification and budget recommendations. I also built its RAG pipeline using OpenAI embeddings, Pinecone, and pgvector, with tests reaching 85%+ coverage on critical financial and AI modules.
