Most SaaS founders don't fail because of bad ideas. They fail because their developer built a prototype, not a product. I build production-ready SaaS platforms and AI-powered applications that ship, scale, and stay stable after launch. At Xevenlabs, I have led architecture and delivery of 15+ production systems across SaaS, AI, e-commerce, and logistics. That includes: → CREUW.AI: Multi-tenant CRE deal pipeline SaaS built on Next.js, Supabase, and Claude API with Stripe subscriptions, OCR document processing, and RLS architecture isolating data across enterprise firms. → Billworth: Congressional transparency platform with 535 US Congress members, Neo4j graph database, Python automated data pipelines, and ProPublica API integration achieving 5ms response times via Vercel edge caching. → Anchor Point: AI-powered commercial property matching platform built on Next.js with intelligent recommendation engine and real-time data processing. → Freightcom Shopify App: Custom LTL freight carrier service with real-time rate calculation via Freightcom API and Laravel middleware. Client went live and received orders on day one. → BigCommerce to Shopify Migration: 142 products, 6,329 customers, and 17,521 historical orders transferred with zero data loss. I don't just write code. I think in systems, architect for scale, and deliver products that work in production, not just in demos. Here is how I work: Every project starts with architecture. I define what should exist in version one, what should wait, and how the system needs to be structured to survive beyond launch. Then we move fast. What I specialize in: · Next.js and Supabase SaaS platforms with multi-tenant architecture and Row Level Security. · AI integrations using Claude API and OpenAI with output caching, streaming responses, and RAG pipelines. · Custom Shopify apps with third party API integrations and carrier services. · MERN stack platforms with real-time features and complex business logic. · Stripe subscription billing with milestone-based access control and webhook handling. · Python data pipelines with automated daily sync and graph database integration. Stack: Next.js, Supabase, React, Node.js, Python, TypeScript, MongoDB, PostgreSQL, Stripe, Claude API, OpenAI, NestJS, Tailwind CSS, Vercel. I work with startups and founders across US, UK, AU, and CA markets. Top-rated on Upwork with 100% Job Success Score and 16 projects delivered.

Need a SaaS MVP shipped, AI built into your product, or a vibe-coded app turned into something production-ready? I've built two production platforms solo — auth, billing, dashboards, AI workflows, the lot — and I do it end-to-end. I'm a full-stack developer (Next.js + Supabase + Node/Python) who ships real products, not prototypes. I built LittlePostManager, a LinkedIn content tool with AI-assisted generation, scheduling, and analytics, and LifeVitals, a medical appointment booking platform with real-time availability and auth — both from database schema to user-facing UI. I also bring an edge most developers can't: I'm a practicing veterinarian as well as a developer, so for anyone building in healthcare, clinical, booking, or records-heavy domains, I understand the problem from both sides. What I can help with 🔹 SaaS MVPs, end to end — I handle scoping through deployment: auth, billing, dashboards, the API layer underneath, and a frontend that scales. Get to market fast without stitching together five contractors. 🔹 AI integration that does real work — OpenAI, Anthropic/Claude, and other providers. Custom workflows, multi-step chains, automation, and MCP server integration baked into your product — not an "AI" badge on a thin wrapper. 🔹 Fixing vibe-coded apps — Built something in Lovable, v0, Bolt, or Replit and hit a wall? I take half-working AI-generated apps and make them functional, secure, and production-ready. 🔹 Backend & API orchestration — Node/Express or FastAPI, Supabase/PostgreSQL, REST and third-party API integration, real-time features. Recent work 🔹 LittlePostManager — LinkedIn content SaaS. AI post generation, scheduling, analytics. Next.js, Supabase, OpenAI. 🔹 LifeVitals — Medical appointment booking platform. Real-time availability, auth flows, clean patient-facing UI. Next.js + Supabase. 🔹 Frontend Lead — Led UI architecture for complex, data-heavy interfaces. Designed component systems and shipped production features across a team. Deployment: Vercel, Supabase, DigitalOcean, and whatever infrastructure fits the project. Tech Stack: Next.js, React, TypeScript, Node.js, Express.js, FastAPI, Python, Supabase, PostgreSQL, Tailwind CSS, shadcn/ui, OpenAI & Anthropic APIs, MCP servers, REST + third-party API integrations, React Native ⭐ Top Rated on Upwork · Available 40 hrs/week · GMT+6 with daily overlap for US/EU syncs If you've got a product to build, an MVP to ship, or an app that's stuck — send me a note with what you're working on and I'll tell you straight how I'd approach it.
