Full Stack Developer on AMC

We are looking for an experienced Full Stack Developer on AMC to take technical ownership of our live e-commerce website and its underlying integrations. The website is built on a headless Shopify architecture, with a custom Next.js frontend and Shopify functioning as the commerce backend. The system integrates with multiple third-party services for payments, authentication, order management, logistics, communication and analytics. This is therefore not a standard Shopify theme maintenance role. The developer will be responsible for maintaining, troubleshooting, monitoring and improving the existing system and ensuring that critical customer and order journeys remain functional. Current Technology Stack Frontend • Next.js 16 • TypeScript • Tailwind CSS • Zustand • shadcn/ui • Framer Motion / GSAP Commerce • Shopify • Shopify Storefront/API integrations • Custom headless implementation Payments & Checkout • Razorpay • Razorpay Magic Checkout • Custom checkout/cart implementation Authentication - Twilio / OTP Order & Inventory - Shopify Logistics - iThink Logistics Customer Communication - WhatsApp / Getgabs Analytics & Tracking • Google Analytics 4 • Google Tag Manager • Meta Pixel • Meta Conversion API Infrastructure • Cloud hosting / deployment infrastructure • Git/GitHub based development workflow What you will be responsible for 1. Website Maintenance - Fix frontend and backend bugs, Resolve responsive/mobile issues, Maintain website performance, Fix broken functionality, Handle production issues 2. E-commerce Functionality - You will be responsible for ensuring that the complete customer journey works: Product → Cart → Checkout → Payment → Order → Fulfilment → Delivery This includes troubleshooting issues involving Shopify, cart, checkout and order creation. 3. Third-Party Integrations - You will need to understand and maintain integrations with: • Shopify • Razorpay • iThink Logistics • Twilio • Getgabs • GA4 • GTM Meta Pixel/CAPI You should be comfortable debugging issues that occur between systems, not just within the website code. 4. Monitoring & Troubleshooting - You may be required to investigate issues such as: • Payment successful but order not created • Inventory mismatch • Cart not restoring • OTP not being delivered • WhatsApp notification not triggered • Shipping information not syncing • Analytics event not firing Website/API returning errors The expectation is that you can trace the problem across the entire system and identify the root cause, rather than simply patching the visible symptom. What we are looking for - You should have strong practical experience with: • Next.js / React • TypeScript • APIs & webhooks • Shopify APIs • Payment gateway integrations • Third-party API integrations • Databases • Authentication • Git/GitHub • Production debugging • Deployment & hosting Strongly preferred Experience with: Headless Shopify Razorpay E-commerce architecture Order management systems Logistics/shipping APIs GA4/GTM Meta Pixel & Conversion API Important: This is an AMC role This is primarily a maintenance, troubleshooting and technical ownership role, not a full-time feature-development position. The expectation is that you will: Understand → Monitor → Diagnose → Fix → Test → Deploy rather than simply receive isolated coding tasks. New features, major architectural changes or substantial development work can be handled separately depending on scope. Before you apply - Please apply only if you are comfortable taking ownership of an existing production e-commerce application with multiple interconnected APIs and third-party services. You should be comfortable entering an existing codebase, understanding its architecture and independently troubleshooting production issues. Experience with Shopify alone is not sufficient. Also, Before we proceed with any discussion, I want to clarify few things: 1. We are a homegrown, self funded brand and have recently started selling 2 months ago however, it's a matter of time as we will turn this brand into a big player and people who join us today will grow with us over the period of time. 2. The scope of work - Our website is ready fully (up and running) - we just need someone to make changes only when asked (changes like change the banner, text, color, sequence, etc) along with any basic issues occurs over time related to any platform - For example payment getting captured on razorpay but orders not reflecting on shopify. or Items are being purchased but the purchase value is not reflecting on Google Analytics.. Anything new (like creating a new product page or new feature all together will be treated separately and will be paid extra). 3. The most important - This project is on AMC - Our yearly maintenance budget is 30K - which means 2.5K per month. But understand that the changes will be minor and some months there will be no changes at all but you will be paid on monthly basis anyway. 4. Why we kept 30K total budget for AMC - because we got the entire website main under 30K. Maintenance cannot be more than development cost.
