Chirag G.

Senior Laravel developer and Flutter app developer for SaaS products, multi-tenant platforms and apps that need rescuing. Top Rated · $100K+ earned · 50 Upwork jobs · Stripe billing · OpenAI and Anthropic integrations Most projects don't fail at launch. They fail 3 months later, when traffic grows, payments break, or the original developer stops replying. I build products that don't. Clients usually come to me with one of two situations: LARAVEL, SAAS AND MOBILE APP DEVELOPMENT "I need this built properly." You have an idea, a spec, or a half-finished MVP. You need someone who thinks about architecture, billing, scaling and deployment from day one, not after it breaks. - Multi-tenant SaaS: subscriptions, RBAC, white-label, dashboards, APIs - Web apps: Laravel, Next.js, React, Vue, Node.js - Mobile apps: Flutter and React Native, published on the App Store and Play Store - Marketplaces: multi-vendor, orders, commissions, automated payouts - Payments: Stripe, Razorpay, PayPal, usage-based billing - Real-time: WebSockets, notifications, chat, Agora video calling - ERP, CRM and internal business platforms LARAVEL AND FLUTTER APP RESCUE "Something is broken and I need it fixed fast." Your developer disappeared. The app crashes. Apple rejected the build. Stripe stopped charging customers. The AWS bill doubled. I regularly take over codebases I didn't write. I read the architecture first, find the actual cause, and fix that instead of rewriting everything around it. - Laravel and PHP apps left behind by a previous developer - Flutter and React Native crashes, plus App Store and Play Store rejections - Slow pages, slow queries and slow APIs - Broken subscriptions and payment webhooks - Failed deployments, server errors and AWS cost problems AI INTEGRATION THAT WORKS BEYOND THE DEMO OpenAI and Anthropic integrations inside real products: RAG chatbots over your own documents, support assistants, document processing, data extraction and AI-powered reporting. Built with rate limiting, cost control, fallbacks and testing, because a demo is easy and production is not. RESULTS FROM PAST PROJECTS - SaaS platform with 500k+ users: dashboard load time cut from 11 seconds to 3 - Telemedicine app: 1,600+ video consultations a month on Agora, with HIPAA-aware data handling - AI support assistant inside a live SaaS: answers from the client's own docs, and support tickets dropped 70% - Marketplace with 1,200+ vendors: commissions and payouts fully automated, replacing manual spreadsheets - Flutter app rescue: crash rate cut by 60% and approved on the App Store within 6 days - Legacy PHP to Laravel migration: 88% faster, with zero downtime at cutover WORKING WITH ME - You talk directly to the developer, not a middleman - Clear scope and estimate before work starts - Regular progress updates and demos you can click, not just status messages - Clean, documented code you fully own - Support after launch, because that's when real issues appear TECH STACK Laravel · PHP · Node.js · Next.js · React · Vue · Nuxt · TypeScript · Flutter · Dart · React Native · Firebase · Supabase · MySQL · PostgreSQL · MongoDB · Redis · REST · GraphQL · WebSockets · Stripe · Razorpay · PayPal · Laravel Cashier · OpenAI · Anthropic · LangChain · RAG · AWS (EC2, S3, RDS, Lambda, CloudFront) · Docker · Nginx · CI/CD · GitHub Actions Send me a message with: 1.
