I was building software before 🤖ChatGPT made “AI expert” everyone’s favorite job title. Hello I am an AI Developer & Automation Engineer with 20+ years in software development and 5+ years in machine learning, AI NLP, natural language processing, and production AI systems. I build Custom AIi products that connect voice, data, CRM, APIs, SaaS platforms, and business workflows into reliable automation. 💡My Best Conversational AI Solutions ✔️ 24/7 customer conversations - I build AI voice systems for inbound and outbound communication, AI Phone solutions that reduce manual call handling, AI agent architectures that execute multi-step tasks, and work as an AI LLM developer on RAG, Claude, GPT-3, gpt3, and other LLM integrations. ✔️ 70% less repetitive support work - for one customer-support workflow, AI Voice Automation reduced manual workload, while an AI Phone setup routed qualified inquiries directly into CRM. An AI agent handled lead qualification and appointment booking, while my AI LLM developer work covered retrieval and response logic. ✔️ 5x faster customer query handling - for a financial-services workflow, an AI voice layer accelerated support, the connected ai phone workflow improved routing and follow-up, and an ai agent reduced manual qualification steps. As an ai llm developer, I built context-aware logic using RAG and API integrations. ✔️ 24/7 customer engagement - for another workflow, ai voice automation handled continuous conversations, ai phone integration connected calls to CRM and scheduling, and an ai agent managed multi-step workflow execution. My AI LLM developer implementation improved document-processing accuracy through structured extraction and intelligent routing. 🤖 Agentic AI & Business Automation ✔️ 60% lower operational processing time - I build agentic workflow systems as an agentic ai developer and ai automation developer. Using n8n, APIs, HubSpot, Retell, cloud services, and custom backend logic, I connect CRM, management tools, messaging, scheduling, and data pipelines through ai automation. ✔️ 3x faster onboarding - I create AI voice experiences for SaaS and service businesses, AI Phone flows with Voip phone infrastructure, and AI agent logic for booking agent, sales agent, pr assistant, quotation, lead generation, and ai lead generation scenarios. My AIi LLM developer work includes prompt engineering, vector search, RAG, API orchestration, evaluation, and guardrails. ✔️ 85% higher document-processing accuracy - my ai voice and automation workflows can combine ai tts, voice talent, narrator-style experiences, multilingual voice, and intelligent routing. My AI Phone implementations support small business automation, business development, customer service, sales, and appointment booking. Each ai agent is designed around measurable business outcomes, while my AI LLM developer approach focuses on scalable architecture, monitoring and secure AIi implementation. 🧠 AI, Machine Learning & Full-Stack Engineering Beyond voice automation, I work on machine learning, computer vision, cameras, image recognition, OCR, web applications, mobile app backend developer tasks, api json, api implementation shopify, and platform integration. I can contribute as a web application developer, systems engineer, full stack developer, senior engineer, architect, consultant, or technical expert depending on the project. I’ve delivered Custom AI for marketing and operations, including facebook ads workflows, ad manager tooling, pinterest marketing, etsy marketing, youtube automation, youtube bot systems, social media marketing automation, content strategy, ai blog workflows, and business automation. I can also automate creative content for a company, including structured text formats such as limerick generation. I collaborate with ai engineers on model pipelines, deployment, automation and SaaS product development. 🎯 AI Consulting & Implementation I advise on AI Strategy as an AI consultant and machine learning consultant, from discovery and architecture to ai implementation, setup, integration and optimization. Whether you need an agent, multi-agent system, agentic workflow, ai automation, custom ai platform, SaaS solution, or business workflow, I can design the tech stack and deliver the system end-to-end. 🤝 If your goal is a production-ready conversational AI system, scalable LLM product, or business automation platform, let’s discuss your use case.
