• Solely led the end-to-end development of Star Phones’ eCommerce platform, including a custom headless storefront and repair booking system, using MedusaJS, Strapi CMS, Next.js, and TypeScript, serving both B2C and B2B needs in the mobile repair industry. • Architected a custom checkout flow that replaced Medusa’s default five-step process with a streamlined experience powered by Stripe Checkout, enabling rapid integration of localized Australian payment methods like AfterPay and Zip Pay, significantly improving conversion rates and reducing customer friction. • Designed and implemented an Express Checkout solution embedded directly into product and cart pages to reduce drop-off and speed up the purchase funnel. • Developed a dropshipping integration with Force Technology AU despite limited API support (only getToken, getAllProducts, createOrder), crafting a resilient cron-based stock synchronization system that ensured daily inventory accuracy with minimal overhead. • Integrated Store Locator using Google Maps API with region-based filtering and address simplification, improving UX for users seeking local repair centers. • Built a comprehensive repair booking system supporting device brand, model, and service type selection, backed by custom logic to handle availability, region-based restrictions, and confirmation workflows. • Implemented Strapi CMS as a central content management hub, enabling marketing and operations teams to manage metadata, SEO tags, dynamic content, and booking flows without developer assistance. • Developed middleware to streamline route management, meta tag generation, and error handling, reducing maintenance overhead across frontend routes. • Leveraged AWS S3 for high-performance image hosting and AWS SES for transactional emails (order confirmations, booking receipts, shipping notifications), with robust logging and monitoring for auditability. • Built a reliable email infrastructure with custom logging, ensuring visibility into delivery issues and improving user communication across order and repair events. • Managed deployment pipelines using Railway, overcoming initial platform unfamiliarity through rapid documentation-driven onboarding, resulting in a stable and scalable production environment. • Led all technical decision-making, UX/UI design (with some exceptions), and integrations, relying extensively on documentation to rapidly ramp up and deliver production-ready features under tight constraints.

• Customized Shopify’s Storefront API and Admin API to support complex B2B workflows, including multi-vendor approval systems and tiered pricing rules, reducing manual order processing by 70%. • Implemented event-driven inventory services using PostgreSQL with LISTEN/NOTIFY and Shopify webhooks, achieving real-time stock synchronization across multiple sales channels with over 98% accuracy. • Extended Shopify’s admin capabilities by developing embedded apps with Polaris and App Bridge for bulk product imports and updates, reducing catalog management time by 65% for operations teams. • Built a high-performance headless storefront using Next.js (React/TypeScript) and Shopify’s Storefront API, leveraging ISR and dynamic routing to handle over 50,000 monthly product updates while reducing page load times by 40%. • Developed custom Shopify apps using Node.js and PostgreSQL to implement B2B-specific workflows (bulk ordering, tiered pricing), cutting checkout abandonment by 30% and automating approval flows. • Architected AWS infrastructure (EC2, Lambda, RDS PostgreSQL) using Terraform and GitHub Actions CI/CD, achieving 99.99% uptime and reducing deployment times from 2 hours to 12 minutes. • Optimized API performance by batching GraphQL calls with DataLoader patterns and caching results in Redis, maintaining 150ms P99 latency under 8K+ RPM traffic spikes. • Built a real-time inventory sync engine using Shopify’s webhook system and AWS EventBridge, preventing overselling across 10+ sales channels (web, mobile, POS). • Integrated third-party services including Stripe, SendGrid, and ERP systems through custom Shopify middleware, streamlining payments, email notifications, and fulfillment workflows. • Led development of a CMS-driven architecture using Sanity.io for structured content and Next.js for dynamic rendering (ISR/SSR), achieving 95+ Lighthouse scores and cutting publishing time by 50%. • Enabled collaborative content editing via Sanity’s GROQ queries and WebSocket subscriptions, achieving 500ms sync latency and scaling delivery through AWS Lambda, S3, and CloudFront. • Streamlined CI/CD with GitHub Actions and AWS CodePipeline, automating schema migrations and production deployments, reducing release cycles from 1 hour to 8 minutes, and enhancing observability with CloudWatch and Sentry.

• Delivered a ReactJS/NodeJS marketplace platform that enabled sales representatives to generate $50K+ monthly revenue, solving critical performance bottlenecks through microservices optimization and implementing Kubernetes cluster auto-scaling to handle 10x traffic spikes during peak sales events. • Modernized a TypeScript/NestJS backend with AWS serverless infrastructure (Lambda, ECS/EKS), reducing API latency by 60% through Redis caching and connection pooling with MySQL RDS, while developing custom CI/CD pipelines with Docker for zero-downtime deployments. • Led a cross-functional team to deliver a React Native mobile app with offline-first capabilities and push notification services, synchronizing seamlessly with our Kubernetes-managed backend to achieve 4.9/5 App Store ratings and 80% user retention. • Designed a high-volume email processing system integrating AWS SES/S3 with custom tracking analytics, enabling representatives to manage 15K+ daily emails directly through the platform while maintaining 99.95% deliverability and compliance with anti-spam regulations. • Improved existing software by correcting errors, upgrading functionality, maintaining code quality, and optimizing performance to enhance user experiences. • Collaborated on the design and implementation of a scalable Customer Relationship Management (CRM) system with Node.js, Express, MongoDB, and React, significantly improving sales productivity and customer engagement. • Partnered with backend developers to build a high-performance e-commerce platform, implementing real-time product recommendations and advanced search capabilities to enhance user engagement and conversion rates. • Refactored and optimized legacy codebases using Redux, resulting in improved performance and reduced operational costs.
