Harsh V.

Senior Laravel and Flutter developer for SaaS products and business apps. I build faster with AI coding agents and review every line before it ships. Top Rated Plus · 100% Job Success · $90K+ earned · 8,700+ hours billed on Upwork Founders rarely lose money on the code itself. They lose it on the developer who goes quiet mid-project, the app Apple rejects twice, and the subscription flow that breaks a week after launch. I stay until your product is live, approved and earning. My longest Upwork engagement ran for 2 years and more than 4,900 hours. LARAVEL AND SAAS DEVELOPMENT - Multi-tenant SaaS: subscriptions, Stripe billing, roles and admin dashboards - Laravel backends: REST APIs, queues, webhooks and third-party integrations - Livewire, Vue, Nuxt, React and Next.js front ends - CRM, ERP, admin panels and internal business tools FLUTTER AND MOBILE APP DEVELOPMENT - Flutter and React Native apps for iOS and Android - Agora live video, RevenueCat in-app purchases, Firebase push notifications and deep linking - One backend designed for both web and mobile AI-ASSISTED DEVELOPMENT I use Claude Code, Cursor, Codex and Gemini every day. AI writes the first draft; I own the architecture, review every change, write tests and ship it safely. You get senior-level quality at a faster pace. - Agent workflows with project rules (CLAUDE.md), so AI follows your codebase conventions - Turning Lovable, Bolt, Replit or Cursor prototypes into production apps - Code, security and performance review for AI-built apps - Tests and code review on all AI-generated code AI FEATURES INSIDE YOUR PRODUCT - OpenAI features inside real products - Document processing, lead scoring, recommendations and smart automation PROJECTS I'VE WORKED ON - AI kids activity platform: Flutter app live on the App Store and Play Store, with a Laravel API - Lead management system: Laravel admin panel with AI lead scoring for a Berlin construction company - Multi-marketplace order manager: orders and inventory from several sales channels in one dashboard - Telephony SaaS portal: multi-tenant Microsoft Teams phone management on Laravel and Azure - Video management CRM: Laravel, Vue and Livewire, with FFmpeg video processing and Redis caching - Truck booking platform: React booking flow, Laravel API and fleet admin panel ALREADY HAVE AN APP THAT'S STRUGGLING? - App Store and Play Store rejections - Broken in-app purchases or subscription renewals - Slow pages, slow APIs and crashing screens - Code left behind by a previous developer, or an AI-built app that breaks in production I find the real cause first, then fix that, not everything around it. HOW I WORK - Clear scope, timeline and estimate before anything starts - Regular updates and builds you can test yourself - Clean, documented, tested code you fully own - Support after launch, because that's when real issues appear TECH STACK Backend: Laravel · PHP · Livewire · Node.js · REST APIs Frontend: Vue · Nuxt · React · Next.js · TypeScript · Tailwind CSS Mobile: Flutter · Dart · React Native · Agora · Firebase · RevenueCat Database: MySQL · PostgreSQL · Redis Cloud: AWS (EC2, S3, RDS) · Azure · Docker · CI/CD · Linux Payments and AI: Stripe · RevenueCat · OpenAI API AI coding tools: Claude Code · Cursor · Codex · Gemini · Antigravity · ChatGPT Tell me what you're building and when you want to launch.
