Adebisi J.

I build AI SaaS products, AI agents, and conversational assistants, and integrate AI into your existing software and business workflows. With 10+ years in software development, I connect the AI, backend, APIs, data pipelines, and user interface needed to deliver a complete application. WHAT I CAN HELP YOU BUILD • AI SaaS & AI integration: AI-powered MVPs, custom LLM applications, and AI features for existing products using Python, FastAPI, React, Node.js, and REST APIs. • AI agents & workflow automation: Agent workflows with LangChain and LangGraph, plus n8n automation and custom Python/API integrations for information processing and connected business processes. • Voice AI & conversational AI: AI chatbots, voice bots, speech-to-text, text-to-speech, and interactive AI avatars. My EdTech work includes a conversational tutor with HeyGen avatars and ElevenLabs voice integration. • RAG & search: Retrieval-augmented generation for document Q&A and knowledge assistants using LangChain and LlamaIndex. This includes vector search, hybrid keyword and semantic retrieval, multimodal RAG, and GraphRAG. I also design Neo4j knowledge graphs with Cypher, entity extraction, and relationship modeling. • Data engineering & ETL: Python and SQL data pipelines, orchestration with Apache Airflow and Dagster, data extraction and transformation, deduplication, and entity/identity resolution to prepare connected data for AI and analytics. • AI consulting & roadmaps: Identify useful AI opportunities, choose an implementation approach, review architecture, and scope a practical first release. Recent work includes an EdTech AI tutor with voice and avatars, an n8n news-processing workflow, a mobile health application with an AI assistant, and a retrieval pipeline combining BM25, vector search, and graph traversal through Reciprocal Rank Fusion. “Joseph successfully helped our team develop a minimum viable product (MVP) for my new healthcare software company.” — 5-star client review I am a Neo4j-certified, and clients consistently highlight my technical expertise, clear communication, and responsiveness to feedback. Tell me what you're building, the tools and data you already have, and the outcome you need. I'll help you define the architecture and first milestone.
