Greenclick

GreenClick β€” Cloud & VPS Management Platform GreenClick is a cloud-based platform designed to provide secure, scalable VPS and virtual infrastructure services. It enables users to purchase, manage, and monitor virtual machines with integrated automation, security, and billing systems. I contributed to designing and optimizing a large-scale CRM and cloud automation platform for customer management, billing, reseller operations, and product provisioning. The system was built using Laravel, React, Redis, and MySQL, ensuring high performance, reliability, and scalability. The platform was deployed on VPS infrastructure using Proxmox, enabling efficient virtual machine provisioning and optimized resource utilization. VM offerings were integrated with Vultr, providing flexible and scalable cloud services. Security was a major focus of the project, with enterprise-grade integrations such as Bitdefender for endpoint protection and Ironscales for email security. Additional infrastructure and backup solutions included Acronis and AnyDesk. The billing and client lifecycle were managed through a customized WHMCS system, automating provisioning, invoicing, and payment workflows. Key Responsibilities & Technologies :- - Designed and optimized a large-scale CRM and automation platform - VPS deployment and management using Proxmox - Automated VM provisioning and lifecycle management - Backend development using Laravel and MySQL - Frontend development with React Integrated cloud infrastructure with Vultr Implemented Redis caching and background job queues Built secure authentication, commission, and invoicing modules Integrated enterprise security tools (Bitdefender, Ironscales, Acronis, AnyDesk) Optimized APIs for high performance and reliability Customized WHMCS for billing and client management Tech Stack: Laravel, React, Redis, MySQL, Proxmox, Vultr, WHMCS, Bitdefender, Ironscales, Acronis, AnyDesk

SATPrepHub - Online SAT Preparation Platform

I architected and developed a full-featured SAT preparation and learning platform focused on delivering personalized, data-driven education at scale. The system was designed to support thousands of students with structured practice tests, real-time performance analytics, and adaptive learning dashboards. On the backend, I designed a scalable Laravel architecture with optimized MySQL schemas to handle large volumes of test data, user activity, and analytics efficiently. Practice tests were built with detailed question tagging, scoring logic, and time-based evaluations, enabling deep insights into student strengths and weaknesses. These insights power personalized dashboards that track progress, accuracy trends, and topic-level performance. For monetization and access control, I integrated Stripe and Razorpay to support secure subscription management, recurring payments, and regional payment flexibility. The billing system was designed to be fault-tolerant, handling edge cases such as failed renewals, webhook verification, and plan upgrades without disrupting the user experience. To improve engagement and real-time communication, I implemented Firebase for live notifications, alerts, and user activity updates. This enabled instant feedback on test completion, subscription status changes, and important platform events. A key differentiator of the platform is the AI-powered RAG (Retrieval-Augmented Generation) system. I designed and integrated an intelligent learning assistant that allows students to ask natural-language questions related to SAT topics. The system retrieves relevant content from a curated knowledge base and combines it with AI reasoning to generate accurate explanations, contextual insights, and step-by-step solutions, helping students understand concepts rather than just memorize answers. Throughout the project, I focused on clean architecture, modular design, performance optimization, and long-term maintainability, taking full ownership from system design to production deployment.

Engineering
Excellence.

Building software is an intellectual craft that demands both foresight and precision. I focus on creating systems that are not just functional, but enduringβ€”balancing strict performance requirements with intuitive, human-centric design. My work is a testament to the belief that the best code is invisible, while the experience it powers is unforgettable.
