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.
