You will get AI-Powered MVP — From Idea to Production
Project details
You have an idea for an AI-powered product — I'll turn it into a deployed, working application your users can sign up for and pay for. Not a prototype, not a mockup, but a real product built on Next.js, Supabase, Stripe, and OpenAI/Claude API. I've shipped multi-tenant SaaS platforms, AI content generators, and billing dashboards — all running in production right now. You get clean, typed code deployed to Vercel that you can maintain, extend, or hand off to any developer. From database design to AI integration to payment processing — one developer, one codebase, fully shipped.

Full-Stack Developer Needed for PropTech MVP (Next.js + Supabase)
Andrii delivered excellent work on the PropRadar project from start to finish.
He was professional, responsive, technically very strong, and handled all feedback and refinement requests with patience and attention to detail. Throughout the project he consistently improved the platform UX, investor flow, mobile responsiveness, and overall product quality based on discussions and testing.
What I appreciated most was his structured approach, clear communication, and willingness to continue polishing the product until everything was working properly across devices and browsers. He also handled the final infrastructure handover professionally, ensuring GitHub, Supabase, Vercel, environment variables, and deployment ownership were fully transferred to my accounts.
The final result is a polished and functional MVP that feels like a real startup product, not just a demo.
I would definitely recommend Andrii to anyone looking for a reliable full-stack developer for SaaS, startup, or web platform projects, and I look forward to potentially working together again in the next phase of PropRadar.

AI-Powered Website Generator Development
Andrii delivered an exceptional, high-performance AI-powered website generator that exceeded all technical requirements. He architected a sophisticated full-stack solution leveraging Next.js and Node.js for a seamless, serverless execution environment on Vercel.
His implementation of Supabase for real-time database management and authentication was flawless, ensuring robust data persistence and low-latency state handling. He demonstrated mastery in integrating complex LLM APIs, optimizing prompt engineering, and managing structured JSON outputs to programmatically generate production-ready UI components.
The project involved intricate API design, middleware optimization, and a deep understanding of modern React design patterns. If you need a developer who understands the intersection of generative AI and scalable web architecture, Andrii is an elite choice. His workflow is efficient, his technical stack is cutting-edge, and the final delivery was a highly performant, production-grade AI platform.

create a V0 website for B2B
Andrii is a standout Next.js and TypeScript developer. He helped me build a complex AI-powered website generator from scratch, successfully integrating Supabase and Vercel for a multi-site architecture. He has a deep understanding of the App Router and dynamic data fetching. He was patient through technical hurdles and ensured the final product met the V0 design specifications perfectly. If you need a scalable, professional web factory, Andrii is your guy. 10/10 would hire again!

Full-Stack Developer (Node/PostgreSQL/React) for Long-Term SaaS Dashboards
Andrii did an excellent job on this developer handoff and initial setup for our Seller Centry Dashboard. He successfully navigated a complex stack (React, Supabase, Google Sheets API) and implemented critical backend logic for our multi-tenant architecture.
He was able to take our existing code, connect the Edge Functions to Google Sheets, and set up the authentication flow exactly as requested. Even though we hit some external roadblocks with Vercel DNS configuration, Andrii's code and logic were solid, and he communicated clearly throughout the process. He is a skilled developer who is easy to work with—highly recommended!

I build the part that has to actually work. I'm a full-stack developer focused on Stripe payments and production-grade AI apps on Next.js + Supabase. Bring me an idea or a half-finished product, and I ship the version that holds up when money and users are real.
What I handle end to end:
— Stripe: subscriptions, metered/usage billing, Connect, Price IDs, webhooks, affiliate & usage tracking
— AI features: OpenAI/Claude integrations, RAG, AI workflows wired into a real product
— Full stack: Next.js, TypeScript, Supabase (Postgres, RLS, Auth), Vercel
— Auth, multi-tenancy, and the unglamorous production glue that keeps it all from breaking
Selected results:
— PropRadar — AI property-comparison platform (Next.js + Supabase). 5★, "technically very strong."
— Stripe Checkout with Price ID + affiliate tracking, plus a full subscription billing dashboard.
— AI website generators for B2B. 5★, "exceptional, high-performance."
How I work: fixed-price with clear milestones. Instead of jumping on a call, I'll send you a deployed demo so you can judge the quality up front. Glad to start with a small paid task.
