Full Stack Engineer & AI Developer | 8+ Years Building Production Systems
I build full stack web apps, AI tools, and automated workflows that handle real traffic, real users, and real money.
What I specialize in:
AI & LLM Applications including RAG pipelines, AI chatbots, conversational AI, document processing, semantic search, and AI agents. Production-grade tools, not API wrappers.
Full Stack Web Applications from MVPs to enterprise platforms. Shipped fintech apps, SaaS products, healthcare systems, e-commerce stores, dashboards, and real estate platforms.
Workflow Automation with n8n and AI that replaces hours of manual work. Email triggers, PDF parsing, data extraction, Slack notifications, CRM updates, invoice processing, web scraping, all on autopilot.
GoHighLevel (GHL) CRM & Sales Ops covering sub-account setup, opportunity pipelines, Conversation AI for SMS and web chat, Voice AI agents that answer calls and book appointments, workflow automations, missed-call text-back, round-robin assignment, nurture sequences, A2P 10DLC, and white-label SaaS-mode rebilling.
Tech I work with:
Frontend: React, Next.js, Angular, Vue, TypeScript, Tailwind, Redux
Backend: Node.js, NestJS, Express, Django, FastAPI, Flask, Python, .NET, C#, REST, GraphQL
AI/LLM: LangChain, OpenAI, Claude API, Gemini, Hugging Face, Pinecone, RAG, vector databases, prompt engineering
Automation & CRM: n8n, GoHighLevel (GHL/HighLevel), Zapier, Conversation AI, Voice AI, A2P 10DLC, Twilio, LC Phone, LC Email, webhooks, web scraping
Databases: PostgreSQL, MongoDB, Redis, Supabase, MySQL, Elasticsearch
Cloud & DevOps: AWS, GCP, Azure, Docker, Kubernetes, CI/CD, Vercel
Not limited to these. I pick whatever works best for your project.
Some things I've done over the past 8 years:
Built a fintech trading platform that processed $15M+ in transactions
Shipped a SaaS product to 10,000+ active users with 99.9% uptime
Set up n8n pipelines that killed 20+ hours/week of manual data entry
Built RAG systems that improved search accuracy by 85% for enterprise clients
Migrated a legacy Python 2.7 codebase to Python 3.10 in under 2 months
Improved React frontend load times by 40% through performance work
Built a full GoHighLevel system for roofing companies with opportunity pipelines, Conversation AI, Voice AI for inbound calls, missed-call text-back, and round-robin routing that turned after-hours leads into booked appointments
How I work:
Honest timelines, not padded ones. Daily updates, clean code, and a product that actually works. Most projects fail because of poor communication, not bad code, so I overcommunicate. 30 days of bug fixes after launch because I don't disappear once the project is done.
Got a project in mind? Send me the details and I'll get back to you within a few hours.
