Since moving to Upwork, that same experience now shows up directly in my client reviews and ratings here. My work goes beyond writing clean code. I build solutions that 𝗰𝗼𝗻𝘃𝗲𝗿𝘁 𝘃𝗶𝘀𝗶𝘁𝗼𝗿𝘀 𝗶𝗻𝘁𝗼 𝗰𝘂𝘀𝘁𝗼𝗺𝗲𝗿𝘀 — because real success is measured in business outcomes, not just shipped features. I stay with every project through launch, maintenance, and long-term support. Hi, I'm Dinesh — a Full Stack Developer with 10+ years of experience across a wide range of stacks and industries. Shopify and React/NodeJS are where I have the deepest track record, but my background covers far more — and I take on new technologies quickly. If you have a project and aren't sure it fits a "specialist," message me anyway; there's a good chance I've already built something similar. ────────────────────────────────────────── 💎 Ruby on Rails Development & Architecture From MVP builds to scaling production systems — I build Rails applications that are fast, maintainable, and ready to grow. ✅ Custom Rails App Development (v5–v8) — MVP to Enterprise Scale ✅ RESTful & GraphQL API Design for Web, Mobile & Third-Party Clients ✅ Microservices & Event-Driven Architecture (Sidekiq, RabbitMQ) ✅ Real-Time Features — Action Cable, WebSockets, Live Dashboards ✅ Database Design & Query Optimization (PostgreSQL, MySQL, Redis) ✅ Legacy Rails Upgrades, Refactoring & Monolith-to-Microservices Migration ✅ Third-Party & Payment Gateway Integrations, Webhooks ✅ AI/LLM Integration — OpenAI, Anthropic Claude, RAG Pipel ────────────────────────────────────────── 🛍️ Shopify Development & Customization From pixel-perfect storefronts to complex backend automations — I build Shopify solutions that perform, convert, and scale. ✅ Custom Theme Development (Liquid) & Figma to Shopify ✅ Private & Public Shopify App Development ✅ Shopify Admin Extensions & Checkout Customization ✅ Shopify Plus — B2B, Merchant Dashboards & Checkout Extensibility ✅ Subscription, Membership & Configurable Products ✅ Shopify API, GraphQL, Webhooks, ERP & CRM Integrations ✅ CRM Integration (HubSpot, Salesforce, Zoho) — Shopify Sync & Automation ✅ Headless Shopify (Hydrogen / Storefront API) ✅ Inventory & Order Automation, AI-Powered Workflows ────────────────────────────────────────── ⚛️ React, NextJS & NodeJS — Full Stack JavaScript From MVPs to enterprise-grade platforms — fast, scalable, and maintainable JavaScript applications. ✅ React 18+ / NextJS — SSR, SSG & ISR for SEO-ready apps ✅ NodeJS & Express APIs — RESTful & GraphQL ✅ State Management (Redux Toolkit, Zustand, Context API) ✅ Real-Time Features (WebSockets, Socket IO) ✅ Authentication & Authorization (Auth0, Firebase, NextAuth, JWT, OAuth2) ✅ Payment Integration (Stripe Checkout, Subscriptions & Webhooks) ✅ Database & ORM (PostgreSQL, MongoDB, Prisma, Drizzle) ✅ Replit — rapid MVPs and prototyping ✅ AWS, Vercel, Netlify & Docker Deployment — CI/CD Ready via GitHub Actions ────────────────────────────────────────── 🤖 AI Automation & Integrations ✅ AI Chatbots & LLM-Powered App Features (OpenAI / ChatGPT API) ✅ FastAPI — AI Backend Services & Model Integrations ✅ n8n — Workflow Automation & AI Agent Pipelines ✅ AI-Assisted Workflow Automation (order processing, data sync, reporting) ✅ Shopify + AI + CRM Workflows — automated lead capture, customer sync & personalized follow-ups ✅ API Integrations connecting AI tools to Shopify, CRM & React/NodeJS apps ────────────────────────────────────────── 🔧 Beyond These Stacks 10+ years in software means I've worked well outside Shopify/React/NodeJS too — other languages, frameworks, mobile, integrations, automation, you name it.
