I build full-stack SaaS platforms, AI agents, and voice automation systems for teams that need real production reliability, not demo-ware. With 5+ years shipping software in fintech and startup environments, I bring engineering discipline from systems that move real money (deposits, withdrawals, coin exchange) into the AI agent and automation space. That background matters: when your voice agent books an appointment or your workflow touches customer data, you want someone who has already built for correctness under pressure.

I believe most businesses don't have a people problem. They have a systems problem. That's why I build AI-powered automation and workflow systems that eliminate manual work, connect disconnected tools, and keep your operations running seamlessly. I didn't start building AI automations because AI was trending. I started because I kept seeing great organizations lose time, opportunities, and impact to broken processes. Working in public health, I watched teams spend hours on manual data entry, missed follow-ups, scattered spreadsheets, and repetitive administrative work. The problem was rarely the people. It was the systems behind them. That curiosity led me into AI automation. WHAT I BUILD AI Agents and AI Chatbots Claude AI, OpenAI, and LangChain-powered AI agents and AI workflows, including RAG chatbots trained on your knowledge base, AI customer support systems, conversational AI, and intelligent assistants deployed across websites, WhatsApp, Instagram, and Facebook Messenger. I focus on practical AI automation that connects AI to your actual business processes, not just standalone chatbots. CRM Automation | GoHighLevel, HubSpot, Airtable I build CRM automation systems for lead capture, qualification, routing, pipeline management, appointment booking, follow-up sequences, notifications, and customer onboarding. Whether you're using GoHighLevel, HubSpot, Airtable, or another CRM, I can connect your lead sources, CRM, communication tools, and internal systems into one reliable workflow.

AI Voice Agents AI voice systems using Twilio, ElevenLabs, Retell AI, and VAPI for inbound and outbound call automation, IVR systems, appointment booking, lead qualification, customer support, and automated SMS follow-up. Document Automation and Document AI Document processing workflows that extract, classify, validate, and structure information from PDFs, reports, emails, and other documents using Claude AI and OpenAI. I build AI-powered document processing pipelines that reduce manual data entry while keeping human approval where it matters API Integrations and Webhooks I connect the tools your business already uses through REST APIs, webhooks, OAuth, and custom integrations. This includes Twilio API, WhatsApp Business API, Shopify API, QuickBooks API, Google Workspace, CRM platforms, databases, and other third-party services. Claude Code and AI-Assisted Development For workflows that go beyond standard no-code capabilities, I build custom automation scripts, Python automations, FastAPI backends, JavaScript logic, and Supabase database integrations. SOP Documentation and Workflow Standardization Every system I build is designed to be maintainable. I provide workflow documentation, SOPs, workflow maps, reusable templates, testing documentation, deployment checklists, and handover guidance so your team can understand, maintain, and replicate the system independently. Today, I design intelligent workflows that connect the tools businesses already use, automate repetitive tasks, and ensure nothing falls through the cracks. Whether it's capturing leads, qualifying prospects, routing leads, sending personalized follow-ups, syncing CRMs, generating reports, processing documents, connecting APIs, or building AI assistants, I create systems that work quietly in the background so teams can focus on what actually matters. For me, automation isn't about replacing people. It's about giving people back their time to do higher-value work while the systems handle the rest. I build n8n automation, AI workflows, CRM automation, API integrations, lead management systems, AI agents, and data pipelines that are reliable, documented, and designed around your actual business process.

Missed calls cost businesses money. Unanswered phones during busy hours, leads that never get a follow up, appointments that slip through the cracks, and staff buried in repetitive manual work, these are the problems I solve by building production ready AI Voice Agents and AI Receptionists.

Every missed call is a missed deal. I build AI voice agents that answer, qualify, and book appointments 24/7 - turning your phone into an always-on revenue system that never sleeps and never drops a lead. I design and deploy custom AI phone agents, AI receptionists, and outbound sales dialers for businesses losing clients to slow response times and manual follow-ups. Using Retell AI, Vapi, and Twilio, I build production-ready voice systems that sound human, think intelligently, and connect directly to your CRM, calendar, and sales pipeline - automatically. ━━━━━━━━━━━━━━━━━━━━━━━ 🏠 REAL ESTATE ━━━━━━━━━━━━━━━━━━━━━━━ Speed wins deals. The agent who responds first wins the listing. I build AI lead qualification agents that call back every new inquiry within seconds - day or night. The agent pre-qualifies buyers and sellers, handles objections naturally, and books showings directly into your calendar without any human involvement. Post-call, n8n or Make com automatically pushes conversation summaries, lead scores, and contact records into GoHighLevel or HubSpot. Your pipeline stays clean, accurate, and actionable - with zero manual data entry. ━━━━━━━━━━━━━━━━━━━━━━━ 🏥 HEALTHCARE & CLINICS ━━━━━━━━━━━━━━━━━━━━━━━ No-shows and unreturned calls are silent revenue killers for healthcare providers. I build AI receptionist agents that handle patient scheduling, appointment confirmations, intake questions, and reminder calls - around the clock, with no hold times and no missed calls. Built with HIPAA-aware conversation flows and integrated directly into your booking system and CRM via n8n or Make com, these agents reduce no-shows, free up your staff, and deliver a smoother patient experience at every touchpoint. ━━━━━━━━━━━━━━━━━━━━━━━ 🏢 SERVICE BUSINESSES ━━━━━━━━━━━━━━━━━━━━━━━ Law firms, HVAC companies, cleaning services, financial advisors - your customers call. If no one answers, they call your competitor. I deploy AI receptionists that answer inbound calls instantly, collect caller details, handle FAQs, and route urgent issues to the right person - while logging every interaction into your CRM automatically. Your team stays focused on delivering the work. The AI handles the front line. ━━━━━━━━━━━━━━━━━━━━━━━ 💻 SAAS & TECH COMPANIES ━━━━━━━━━━━━━━━━━━━━━━━ For SaaS companies, I build AI voice agents that handle onboarding calls, churn-prevention outreach, renewal follow-ups, and Tier 1 support triage - integrated into your existing stack via webhooks and APIs. I also use Lovable and Base44 to rapidly build and ship the AI-powered web interfaces that give your team or clients direct control of their voice agent - fast to deploy and connected to everything. ━━━━━━━━━━━━━━━━━━━━━━━ 🛒 E-COMMERCE ━━━━━━━━━━━━━━━━━━━━━━━ I build outbound voice agents that follow up on abandoned carts, confirm orders, collect post-purchase feedback, and handle delivery or return inquiries automatically - cutting support ticket volume and improving retention without adding headcount. ━━━━━━━━━━━━━━━━━━━━━━━ ⚙️ WHAT I BUILD WITH ━━━━━━━━━━━━━━━━━━━━━━━ → Retell AI & Vapi - sub-second latency, natural human-like voice AI at scale → Twilio - telephony infrastructure, SMS automation, and intelligent call routing → n8n & Make com - end-to-end workflow automation connecting every tool you use → GoHighLevel - CRM, pipeline management, and booking automation → Lovable & Base44 - rapid AI-powered web apps and client-facing dashboards → HubSpot, Salesforce, Google Sheets - CRM integrations for any business size Every system I build is fully connected. Your AI agent doesn't just talk - it triggers real business actions from the moment the call ends. ━━━━━━━━━━━━━━━━━━━━━━━ 📞 READY TO BUILD? ━━━━━━━━━━━━━━━━━━━━━━━ If missed calls, slow follow-ups, or manual lead handling are costing you clients and revenue - I can build an AI voice system that fixes that permanently. Message me. Let's map out your use case and build something that actually delivers results.
