Next.js SaaS Engineer | React | Node.js | TypeScript | AI Integration

I build production Next.js SaaS applications, the parts that actually matter: multi-tenant auth, Stripe billing, reliable APIs, and AI features that fail gracefully instead of breaking the app. Top Rated · 100% Job Success · 12 completed jobs · 7+ years full-stack experience Before freelancing, I worked as a Senior Full Stack Developer at Meltwater, and earlier as a Web Developer at Home Delivery, production experience that carries into how I scope and ship client work today. Core stack: Next.js, React, Node.js, TypeScript, PostgreSQL, Supabase, Firebase, Stripe, OpenAI API Completed work on Upwork: - TripTalk: AI travel SaaS (Next.js + OpenAI) built for Drew Binsky's audience. Streaming chat, voice AI assistant, personalized itineraries across 2,000+ guides. Live product, 4.9/5 rating. - Subscription SaaS platform: built the billing, onboarding, and account architecture from scratch. Reached $40K MRR within six months. - Figma-to-production build: 275-hour engagement converting detailed designs into a pixel-accurate, responsive React/TypeScript interface. $8,250 completed contract. - Custom UGC collection platform: fixed-price build delivered on time to spec, five-star outcome. $3,000 completed contract. Before writing code, I map what causes rewrites later: user roles, database schema, API contracts, Stripe billing states, and deployment plan, so milestones are concrete, not guesses. Send me your product stage, current stack, and target launch date. I'll flag the highest-risk area and define the first milestone.
