Full Stack Developer for AI Integration & Automation Setup
Working with Derek was a genuinely positive experience. As a Full Stack Developer for AI Integration & Automation Setup, he quickly understood our needs and delivered the AI assistant and automation workflows faster than expected, without cutting corners.
He handled backend integrations, the frontend interface, and the automation logic smoothly, which made the project feel truly end-to-end. Communication was clear and consistent throughout, the process ran smoothly, and the final solution fit our business needs exactly.
I’d happily work with him again and recommend him for similar projects.

Figma Designer for Landing Page Template (Using Existing Webflow Design)
Derek is a very skilled designer. He took the time to understand our needs and helped us work out possible issues before they became a problem. His Figma File was impeccable and super easy to hand off to our dev team. I hope to work with him again soon.

Job Success
Colton, United States - 4:55 pm local time
I'm a Top Rated full-stack developer building AI-integrated Web Apps, SaaS MVPs, and high-converting Marketing Websites that turn those products into businesses.
Primary stack is Next.js, Node, and Postgres (React, Python/Django, MongoDB, Angular when a project calls for it). I ship real LLM features with OpenAI and Claude: retrieval, tool use, and evals. Not duct-taped demos.
12+ years in Web and Product work, the last several focused on Full-stack and AI features for SaaS, Fintech, Professional services, and DTC e-commerce. I do strategy, UX, design, and the code. One brain, one timeline, one invoice. No Figma-to-dev gap, no scope surprises.
____________________________________________________________
WHAT I BUILD FOR CLIENTS
✅ Full-stack Web Apps on Next.js, React, Node, Postgres
✅ AI features: chatbots, RAG over your docs, AI content tools, document Q&A, agentic workflows
✅ LLM API integrations (OpenAI, Claude) with retrieval, tool use, and streaming
✅ SaaS MVPs with auth, billing, dashboards, admin panels
✅ Conversion-focused marketing sites on Webflow, Framer, HubSpot, or custom WordPress
✅ WooCommerce and headless e-commerce stores
✅ Figma design systems translated to production React or Webflow
✅ Core Web Vitals, technical SEO, and local SEO baked in from day one
____________________________________________________________
WHY CLIENTS HIRE ME OVER A DESIGNER + DEV + AI CONTRACTOR
Most founders try the cheaper path first. They hire a designer, then a separate dev, then a third contractor to "add the AI part." Three months later: three vendors blaming each other, a product that doesn't match the mockup, and a launch date that keeps slipping.
I do all of it. One brain, one timeline, one invoice.
→ Strategy, UX, design, and full-stack build, all me
→ Production-ready AI: retrieval, evals, cost controls
→ Fixed-scope, fixed-price quotes with no hourly creep
→ Loom walkthroughs at every milestone, so you're never guessing
→ Webflow Expert Certified + Advanced WordPress Developer Certified
____________________________________________________________
WHO I'M A FIT FOR
✅ SaaS and fintech founders launching, rebranding, or rebuilding a product
✅ Teams adding their first AI feature (chatbot, RAG, content tools, agentic workflows)
✅ E-commerce and DTC brands scaling past six figures
✅ Professional service firms (legal, dental, finance) ready to dominate local search
✅ Agencies needing a reliable Figma-to-Webflow or Figma-to-React partner (white-label OK)
❌ Anyone looking for the cheapest Webflow developer on Upwork. I'm not that, and that's not a fit either way.
❌ Anyone who wants AI buzzwords slapped on without a real use case. I'll talk you out of it.
