I build AI systems that run real operations, not demos. Voice agents that handle live calls, automation workflows that qualify and follow up on leads, and full-stack SaaS platforms that connect CRMs, calendars, payments, and dashboards. 10+ years building web and AI applications. Top Rated Plus with a 100% Job Success Score. Recent work includes a roofing AI system that recovers missed calls within seconds, a landlord compliance SaaS for Baltimore City, and a legal document abstraction engine using Claude and Azure Document Intelligence. What I build: AI Agents and Custom Automation I design AI agents, multi-agent workflows, and custom business process automation that handle real operations end to end: lead qualification, follow-up, document processing, customer support triage, and internal ops. Built with custom code and API integrations (webhooks, REST, third-party platforms), with human-in-the-loop approval where it matters, using OpenAI and Claude. I architect these as clean, maintainable systems, not brittle scripts. Full-Stack SaaS and MVPs I take validated ideas to working, multi-tenant SaaS products: user accounts, dashboards, admin panels, role-based access, subscriptions, and reporting. Stack: Next.js, React, Node.js, Nest.js, Python, FastAPI, Supabase, PostgreSQL, Stripe, and cloud deployment on AWS and GCP. Milestone-based delivery with a working build at every checkpoint. RAG and LLM Applications I build retrieval-augmented generation (RAG) systems and document intelligence pipelines: chat-with-your-documents, knowledge bases, structured extraction, and grounded, no-hallucination outputs. Using LangChain, Pinecone, Chroma, vector embeddings, prompt engineering, and contextual memory across GPT-4, Claude, Llama, and others. CRM and Lead Management Systems I build AI-driven lead management and CRM platforms: multi-source lead intake, AI lead scoring and qualification, automated follow-up sequences, pipeline tracking, and conversion reporting in a single dashboard. Voice and Conversational AI I build conversational and voice agents using Deepgram and Whisper (speech-to-text), ElevenLabs (text-to-speech), and Twilio and SignalWire for real-time call and IVR workflows.
