Projects We've Delivered

Squarebrackets E-Learning Platform

Enterprise-grade learning management engine built for distributed technical cohorts

Our development studio engineered a custom learning platform designed for live cohorts, automated code assessments, and AI/ML solution workflows across distributed engineering teams. Built on modern cloud infrastructure, the system serves technical learners in Delhi NCR and worldwide with sub-second lab provisioning and zero video latency during peak class hours. The implementation replaced three disconnected third-party tools, consolidating attendance, assignment pipelines, and student progress tracking into a single production codebase.

SkillOceans Edtech and Training Platform

A high-concurrency learning management platform built for modern tech training

We built a scalable, cloud-native learning management platform for SkillOceans to deliver live-streamed lectures, automated coding assessments, and interactive progress tracking. The platform successfully handles thousands of concurrent student sandbox environments while reducing infrastructure overhead by 40%. This deployment has enabled seamless course delivery and real-time mentor feedback across multiple tech stacks.

Beachfront Paradise

A high-performance short-term rental booking engine for coastal stays

We built a responsive, real-time booking web application designed for boutique coastal properties and holiday homes. The platform features an interactive availability calendar, secure payment gateway integration, and an intuitive admin dashboard for property hosts to manage reservations. The final product achieved a sub-two-second page load time and processed booking confirmations instantly.

Squarebrackets

A full-stack learning platform powered by Next.js and Spring Boot

We built a production-grade learning management and automated deployment portal for our Noida campus. The platform integrates a Next.js frontend with a Spring Boot microservices backend, allowing students to write, test, and deploy full-stack applications directly onto AWS sandbox environments.

Short-Term Vacation Rental Platform

Build a secure and scalable booking engine with Php.

We engineered a fully functional short-term vacation rental platform featuring real-time property search, interactive maps, and a secure payment gateway. Designed for property managers and travelers, the application handles concurrent booking requests and automated email confirmations using a microservices architecture. The final project demonstrates production-ready state management and clean API design.

Enterprise AI Consulting Platform

A high-performance client portal built with Next.js and Spring Boot

We built a modern, SEO-optimized consultant website and client portal for an enterprise AI advisory firm. The platform features a dynamic Next.js frontend with Tailwind CSS for rapid page loads, backed by a robust Spring Boot microservices API managing client onboarding, secure document sharing, and automated meeting scheduling.
