Project History
AI Enterprise Automation and Intelligent Knowledge Platform
https://hcompany.ai/• Implemented a retrieval-augmented generation (RAG) architecture with OpenAI GPT/Azure OpenAI, LangChain, LlamaIndex, and vector databases (Pinecone, FAISS, and ChromaDB), delivering highly accurate, domain-specific responses.
• Built advanced AI agents using LangChain Agents and LangGraph for multi-step reasoning and autonomous workflows, reducing cross-system task time by 50%.
• Developed AI-powered features, including chatbots, document summarization, automated reports, and knowledge copilots, enhancing productivity and minimizing errors.
• Orchestrated automation workflows with n8n, Apache Airflow, OpenClaw, Zapier, and Make for seamless API integration and business process automation.
• Integrated AI services securely via REST APIs and asynchronous processing with Python/FastAPI and microservices.
• Deployed on Azure Cloud with RBAC, OAuth 2, and encryption, while using LangSmith for observability and continuous model optimization, achieving measurable operational efficiency gains.
Clipyard
• Built Clipyard, an AI-first marketing automation platform that accelerated video ad creation by 70% and automated lead pipelines, saving agencies 50+ hours of manual work monthly.
• Built an autonomous agent framework using OpenClaw, enabling AI “employees” to execute multi-step marketing workflows across third-party apps, maintaining brand consistency and high content quality.
• Integrated GoHighLevel (GHL) API to automate CRM tasks, including lead follow-ups, appointment scheduling, and social media posting, driving a 30% increase in conversion rates.
• Implemented a multi-LLM orchestration layer (Claude 3.5/4 and Gemini 3.0 Pro) for creative copywriting and large-scale data analysis.
• Engineered an AI video and computer-vision pipeline (Veo, Sora, Kling AI, OpenCV, object detection/tracking, CNNs, speech-to-text, audio/image processing) for cinematic ads, brand avatars, and auto-captioning, cutting production time 60%.
• Orchestrated workflows via n8n for real-time multi-channel lead engagement.
• Built a scalable Python microservices architecture and React dashboard for monitoring AI activities, reviewing video drafts, and tracking conversions, making campaign management faster, smarter, and measurable.
AI-powered Customer Support Chatbot
https://decagon.ai/I extended it into an omnichannel assistant with real-time systems over WebSockets and event-driven webhooks, plus Twilio SMS and email automation (SendGrid, Nodemailer) for proactive order and support updates. Workflow automations and third-party API integrations connect the bot to the client's CRM and fulfillment tools. The assistant handles 2,000+ conversations per day autonomously, cut support ticket volume by 45% in the 1st month, and reached 92% response accuracy.
Intelligent Document Q&A System with RAG
https://www.glean.com/Document processing handled PDF parsing and OCR on scanned filings, using Pandas for tabular data extraction and Pydantic for schema validation. Persistence and metadata were handled with SQLAlchemy, with Flask and Django services for ingestion and admin tooling. I implemented a hybrid search that combines dense embeddings with BM25 keyword retrieval and metadata filtering by document type, date range, and compliance category to ensure precise, auditable results. Quality was enforced with Pytest-based automated and unit testing across the pipeline.
Multi-agent AI Workflow for Lead Generation
https://www.artisan.co/I built the orchestration and tool layer in Python/FastAPI, with web scraping and data mining via Beautiful Soup, Scrapy, and Selenium, enriched against 3rd-party APIs. Qualified leads sync bidirectionally to CRMs—Salesforce and Microsoft Dynamics—while Workato, Airtable automations, and Google Sheets drive downstream workflow automation and reporting. The system saved 20+ hours of manual prospecting per week, tripled the qualified lead pipeline, and cut the agency's clients' cost per lead by 60%.
AI Automation Pipeline for Real Estate CRM
AI-powered Content Generation Platform
https://writer.com/The front end is a Next.js app with a Tailwind CSS design system and styled-components (HTML/CSS3), a React Flow visual workflow builder, and a micro-frontends front-end architecture built for strong UI/UX and UI design (prototyped with Lovable), bundled via Vite and Webpack. I shipped premium content subscriptions with Supabase, Clerk auth, and Cloudflare as a productized SaaS. The platform handles 10,000+ daily API requests at 99.9% uptime, increased client content output 10x, and cut production costs by 70%.
