I've built backend features and automation workflows at Origen Systems using JavaScript, Node.js, MongoDB, REST APIs, webhooks, ERPNext, and CRM platforms. My work streamlined operational workflows and reduced repetitive communication and manual effort through WhatsApp Business API automation and Google Apps Script.
At Rerok, I contributed to MERN-stack web applications across frontend and backend functionality, while improving website layouts, pages, user experience, branding, and e-commerce workflows.
I've built a coding assessment platform supporting 100+ concurrent users with Redis caching, JWT authentication, role-based access, AI-powered feedback, and Cloudinary video delivery. I also built a Django HRIS import platform with CSV validation, graph-based reporting analysis, and automated tests, and have solved 300+ DSA problems.
