And I know how to use them. Whether you're drowning in manual follow-ups, losing leads because your pipeline is broken, or watching your competitors outpace you with half the team, I've been there. I've fixed it.

Hey, I'm Seth. I build CRM and AI automation systems that take the repetitive, manual work off your team and run it reliably in the background using tools like GoHighLevel, HubSpot, Email Campaigns, Claude, n8n, and many more. Top Rated, 100% Job Success across 50+ projects. Scroll down to my project catalog for fixed price packages on the systems I build most, with starting prices on each to give you an idea on cost. Audits start at $650 and credit toward the build. Single workflow builds start at $800. Full systems start at $2,500 and scale with the number of tools connected and workflows involved. Anything more custom, shoot me a message and we'll scope it out. Either way, feel free to send me a message and I'll send you a video back on what's possible! I run this as a solo practice. I am not an agency, and this is not a freelance side hustle. You work directly with me, and most of what I deliver comes from a catalog of systems I've built and shipped hundreds of times. Before starting my practice at Launch Forte, I spent years as a Senior Software Engineer at Wells Fargo, where the systems I ran could not afford to go down. Most automation breaks without anyone noticing. A workflow fails overnight, and a week later a lead never got a follow up or an invoice never went out. I build automation that holds up, with monitoring and error handling built in, because that is the standard I came from. What I build CRM and pipeline systems. Full builds and rescues in GoHighLevel and HubSpot. Lead intake, nurture, booking, reporting, and the pipeline and revenue operations that carry a contact from first touch to closed without anyone retyping data. AI automation with Claude and OpenAI. Document processing, lead scoring, content generation, research, and customer support wired directly into your CRM and tools. Production systems built to run unattended inside your stack. Workflow and app integration. n8n, Make, Zapier, and Power Automate connected across the tools you already use, with custom integration down to the API and webhook level. Finance and operations automation. QuickBooks and Xero work, from invoicing and reconciliation to the back office tasks that eat hours. I have built capital call automation for an investment firm and order to accounting syncs for ecommerce brands. How I work Fixed scope, fixed price, fixed timeline, and no surprise invoice at the end. You know exactly what you are getting and what it costs before we start. I document everything and train your team, so you are never stuck waiting on me for a small change. I respond fast and keep the work visible the whole way through. Every project is measured against a result you care about. I am a military veteran, and the same discipline shows up in how I build and how I communicate. I do my best work with small and growing businesses in med spa, home services, real estate, and financial firms, where one good system changes the whole week. If you have a process that should be running itself, send me a message and tell me what is eating your time, and I'll send a short video back on how I would build it. NOTE: All builds are scoped as value based milestones. Hourly rate is for consultations.

I build AI automation systems, AI agents, and chatbots that connect OpenAI, Python, APIs, CRMs, documents, and business workflows into practical tools that reduce manual work. I bring 7+ years of Python automation, backend workflow, and API integration experience, with current focus on AI automation, AI agents, OpenAI integrations, RAG chatbots, LLM output validation, data extraction, and business process automation. My work is useful for SaaS companies, FinTech platforms, healthcare and service operations, agencies, sales teams, support teams, and document-heavy businesses that need AI connected to real tools, users, and data. For SaaS products, I help build AI features inside existing platforms: AI support assistants, product knowledge chatbots, onboarding workflow automation, internal admin tools, API-connected dashboards, and Python/FastAPI backend automation. For FinTech and finance workflows, I help with financial document processing, tax analysis support, structured data extraction, reporting workflows, LLM output validation, and API-connected automation where accuracy, clean data handling, and reliable business logic matter. For healthcare and service operations, I help with intake workflows, appointment/admin process automation, document Q&A, internal knowledge assistants, support chatbots, and operational workflow systems. I focus on automation, support workflows, document handling, and process efficiency, not replacing clinical judgment. I can help with: • AI automation for sales, support, admin, research, operations, and internal workflows • AI agents that use OpenAI, tools, APIs, structured outputs, databases, and business rules • AI chatbots for SaaS products, websites, support systems, internal teams, and knowledge bases • RAG chatbots for PDFs, websites, product documentation, company knowledge bases, and internal support content • CRM and lead workflow automation using OpenAI, APIs, backend logic, data enrichment, lead qualification, and structured pipeline updates • Data extraction, web scraping, document processing, PDF parsing, lead generation automation, and structured data pipelines • LLM output validation and reliability checks for chatbot responses, AI summaries, document Q&A systems, and internal AI workflows Core stack: Python, FastAPI, OpenAI API, LangChain, LlamaIndex, RAG, AI agents, REST APIs, PostgreSQL, MongoDB, vector databases, data extraction, web scraping, n8n, Make .com, and workflow automation. Relevant project experience includes a RAG document chatbot for PDF Q&A, lead generation automation using Python web scraping, LLM hallucination detection and output validation, and an HR workflow automation app for hiring, booking, messaging, scheduling, and dashboard tracking. My approach is practical. I first understand your workflow, tools, data sources, manual steps, expected outputs, and failure points. Then I design the automation flow, backend logic, API structure, database flow, retrieval strategy, and testing path before building. This helps avoid the common AI project problem: a demo that works with sample data but fails when real users, messy inputs, API errors, document edge cases, or business rules appear. If you need an AI automation expert for an AI agent, chatbot, OpenAI integration, RAG system, CRM automation, Python/FastAPI backend, document workflow, SaaS AI feature, FinTech automation, healthcare workflow automation, lead generation automation, or API-driven business process automation, send me your use case and I will suggest the cleanest technical approach.
