Is your business losing sales because of a slow website, manual processes, or no online presence? I build software that directly grows your sales and saves your time. How bad software kills your sales: → Slow website = customers leave before buying → No online store = you miss sales happening right now → Manual order tracking = mistakes and unhappy customers → No admin system = you are stuck doing everything manually What I build to fix it: - Online stores that convert visitors into buyers - Payment systems — Stripe, cards, cash on delivery - Order and inventory management — automated, error-free - Fast websites that keep customers engaged - Admin panels so you run everything without a developer - SMS and email notifications for every order automatically I built OxyBliss — a live clothing store where the owner manages everything independently after handoff. No developer needed. That is the standard I deliver for every client. If your business is losing sales due to missing or broken software — let's fix it. I will build something that works while you sleep.

Integrated systems rarely break on the first successful API call. They break three weeks later: a failed Shopify webhook, an ERP order that never synced, a CRM contact missing from the pipeline, or POS inventory that no longer matches the store. I build and fix the middleware/API layer behind those systems. My strongest work is around Shopify, ERP, CRM, POS, and Laravel-based backend systems where product data, orders, inventory, customers, payments, and reporting all need to stay aligned. What I usually handle: - Shopify / Shopify Plus integrations and custom commerce workflows - ERP and CRM syncs: Acumatica, Salesforce, Zoho, HubSpot, SAP-style systems - POS and inventory workflows: Clover, store operations, loyalty, order flows - Laravel/PHP middleware, APIs, webhooks, queues, cron jobs, retries, and logs - Admin dashboards, reporting panels, and operational data models - Production debugging where the issue is hidden across multiple systems Relevant background: - Built and supported systems handling 24k+ products, 3M+ users, and 2,000+ locations - Led technical delivery across teams of 20+ - Worked across Shopify, Shopify Plus, Magento, BigCommerce, Acumatica, Salesforce, Zoho, Clover POS, Laravel, REST/GraphQL APIs, PostgreSQL, MySQL, AWS, Firebase, and payment systems I also take on SaaS MVPs and React Native app work when the project depends on backend architecture, integrations, subscriptions, analytics, or production stability. If your store, ERP, CRM, POS, or internal dashboard is held together by fragile syncs and unclear data flow, I can help trace where it breaks and make the system reliable.

 I'm a Software enthusiast with over 14 years of development experience. I am an expert in Javascript (Node.js, React.js, Vue.js & Angular.js) and all things PHP (Laravel, Magneto, Wordpress, Drupal, Shopify, YII, CAKE) and their complimentary mobile applications (Native Android, IOS, Flutter and React Native to develop applications). I am also experienced with Python, if that is your preference. Along my journey creating web applications, websites, and mobile applications I have contributed to several open-source libraries along the way. I have a strong base in software development with an awesome educational record in my curricula. Over the years, regardless of the technical challenge, I solve the issue with great precision and accuracy. Whether working autonomously or with a team I always exceed best practices, stringently employing version control systems (BitBucket, GIT, Deployment Pipes, Jenkins, etc..), and excel within Linux, AWS, CDNs, S3, Amplify , RDS, etc… I'm addicted to clean workflow using testing frameworks like Karma, Mocha, and Tape. I'm also a part of a team creating a cross-platform desktop application in Electron.js. I have sharp skills in database systems including MySQL, NoSQL databases, and Graph databases like OrientDB and Neo4j. I am Swiftlane api Integrator partner I write impeccable and maintainable code, building a reusable foundation, while also keeping my clients updated about emerging technologies. If the project involves a new technology, I easily and quickly become proficient in the new technologies without any complications, with hundreds of successfully completed projects. 
I look forward to working with you, Arun
