You will get Professional SaaS MVP Build | React + Node.js | Full-Stack Web App
Project details
I build production-ready SaaS MVPs — not prototypes that need to be rebuilt. You get a fully functional web application with user authentication, role-based access, your core features, an admin dashboard, payment integration (Stripe or Razorpay), and deployment to production infrastructure. Built with React/Next.js, Node.js, and PostgreSQL or MongoDB. Every project starts with documented requirements and acceptance criteria before development begins — so what gets built is exactly what you approved.

Website Design for Student Test Bank with Payment Integration
I offer my highest possible recommendation for Lavesh and his team. I asked him to create a website where users could subscribe and pay for my product. He did a fantastic job and completed the project on time. Specifically his communication is excellent, always on time and thoughtful. He clearly had experience in the field and provided very useful suggestions. He took the entire process from A to Z so that this all required little work from my end. I am extremely satisfied with the website he built and the seamless integration with payment and email support that I requested. He was receptive to feedback for any small changes to the website and he was dedicated to supporting its functionality. He completed the project within the requested timeframe.

Website & Membership Portal Development for PingTag
Lavesh and his team did good work and were responsive on revisions. The turnaround was fast, but the revisions didn't always go deep enough for what the project required. I've decided not to continue with the team on this one.

AI Developer for AI Travel Agent
The Fonixtec team was great to work with. Communication was clear and consistent, and they were very responsive throughout the project. They were flexible and made unlimited changes and edits to help improve and fine-tune the AI model. Overall, a very smooth and positive experience. Would happily work with them again.

Build MVP for Peer to Peer Fashion Rental Marketplace (React, Node.js, Stripe)
Working with this team on Phase 1 was a great experience. They immediately understood the vision, collaborated proactively and delivered everything on time.
Communication was excellent - I always felt in the loop, and they were available to support at any hour when needed. Issues were handled quickly and efficiently, often within a matter of hours. I’m very pleased with the results and would highly recommend them.

My strongest work happens at the intersection of product thinking and technical execution. I don't just write code — I start with documented requirements, define acceptance criteria and edge cases upfront, and deliver against specs you've signed off on. Fewer surprises, fewer "that's not what I meant" moments, and software that works the way you expected.
𝗪𝗵𝗮𝘁 𝗜 𝗕𝘂𝗶𝗹𝗱:
𝗦𝗮𝗮𝗦 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀 — Multi-tenant subscription products with real billing complexity: free trials, upgrades with mid-cycle proration, downgrades, failed payment dunning, usage-based plan limits, role-based access control, and admin dashboards with analytics, bulk operations, and data export. React/Next.js, Node.js or Laravel, PostgreSQL or MongoDB, Stripe or Razorpay.
𝗔𝗜-𝗣𝗼𝘄𝗲𝗿𝗲𝗱 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝘀 — This is where I do my most differentiated work. RAG systems where AI answers questions from your specific documents (contracts, policies, catalogs) with source citations and confidence thresholds. LLM-powered chatbots and automation agents using OpenAI, Claude, or Gemini. OCR and document intelligence for invoices, IDs, and forms. For data-sensitive projects, I deploy self-hosted models (LLaMA, Mistral) on RunPod so your data never leaves your environment. Python/Django orchestration, LangChain, Pinecone/Weaviate/pgvector.
𝗠𝗼𝗯𝗶𝗹𝗲 𝗔𝗽𝗽𝘀 — Cross-platform iOS + Android with React Native. I handle what most developers miss: offline behavior, push notification flows, platform differences between iOS and Android, deep linking, device permissions, Apple Sign-In compliance, and App Store/Play Store submission.
𝗘-𝗖𝗼𝗺𝗺𝗲𝗿𝗰𝗲 & 𝗠𝗮𝗿𝗸𝗲𝘁𝗽𝗹𝗮𝗰𝗲𝘀 — Full commerce builds with payment gateway integration (including webhook handling and idempotent processing), order state machines, inventory, shipping integration, and separate seller/buyer dashboards for marketplaces.
𝗔𝗣𝗜 𝗕𝗮𝗰𝗸𝗲𝗻𝗱𝘀 & 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀 — Backend services consumed by your existing frontend, third-party system integrations, real-time features via WebSocket, and data-heavy dashboards with complex filtering and reporting.
𝗛𝗼𝘄 𝗜 𝗪𝗼𝗿𝗸:
Every project starts with documented feature specs — screens, user actions, success states, error states, edge cases — with acceptance criteria so "done" is never ambiguous. Designs are reviewed against requirements before development begins. During the build, you get proactive updates. If something is outside scope, I flag it before building it. Before delivery, everything is tested against signed specs and you get a staging walkthrough to verify.
