Modernizing Hardware Commerce Through Intelligent Automation
A full-stack e-commerce and inventory management platform engineered for Sri Shasta Engineering Works, transforming traditional hardware retail into a scalable digital operation.
Project Overview
A comprehensive digital transformation initiative developed over 2-3 months, revolutionizing how a traditional hardware tools business manages operations.
The Challenge
Sri Shasta Engineering Works faced critical operational bottlenecks with manual order processing, inventory chaos, and communication gaps. The business struggled with time-consuming manual processes, high error rates, lack of real-time visibility, and inability to scale during peak periods.
The Solution
The team designed a cloud-native e-commerce platform featuring a customer-facing storefront with intuitive browsing and real-time order tracking, plus a comprehensive admin dashboard for unified seller portal, catalog management, and business analytics.

Commerce Service (Java/Spring Boot)
The brain of the platform, handling authentication, catalog management, order processing, and email notifications. Built with Clean Architecture patterns, SOLID principles, and Spring Security for enterprise-grade reliability.
Telemetry Service (Go/Gin)
Purpose-built for high-concurrency operations, handling 10,000+ concurrent polling connections with sub-300ms latency. Leverages Go's goroutines for exceptional performance and minimal memory footprint.
Key Features
Engineered solutions addressing real-world business challenges with modern technology.
Real-Time Order Updates
Event-driven long polling architecture providing instant order status updates without WebSocket complexity. Handles 10,000+ concurrent connections with automatic reconnection.
Smart Image Management
AWS S3 integration with presigned URLs for secure, time-limited access. Direct upload/download reduces server bandwidth by 90% while maintaining security.
Async Email Processing
Non-blocking email system with Redis Streams and exponential backoff retry. Processes 1000+ emails per minute with 99.9% delivery success rate.
Dynamic RBAC
JWT-based role system with granular permissions. Supports multi-session management, token refresh, and permission caching for enterprise security.
Smart Caching
Multi-layer caching with Redis achieving 85% hit rate. Tag-based invalidation ensures data freshness while reducing database load by 70%.
CI/CD Pipeline
GitHub Actions workflow enabling 15-minute deployments from commit to production. Zero-downtime deployments with automatic rollback on failures.
Technology Stack
Carefully selected technologies optimized for performance, reliability, and maintainability.
Performance Metrics
Production-tested results demonstrating system capabilities and reliability.
Business Impact
The platform achieved remarkable operational improvements: 90% reduction in manual order processing time, 95% reduction in order errors, 80% faster inventory updates, and 3x increase in order capacity during peak seasons. The business can now handle growth without additional staff while maintaining improved customer satisfaction through real-time updates.
Development Team
A collaborative effort between backend and frontend specialists delivering enterprise-grade solutions.
Aryan Singh
Backend Engineer & DevOps
Architected and implemented the complete backend infrastructure including polyglot microservices, database design, AWS deployment, CI/CD pipeline, and security systems. Achieved sub-300ms response times and 10,000+ concurrent connection handling.
Engineering Challenges
Complex problems solved with innovative technical solutions.
Real-Time Without WebSockets
WebSocket limitations behind corporate proxies led to implementing event-driven long polling with Go. Result: Universal compatibility with near-instant updates and lower resource usage.
Image Upload Performance
Initial server-proxied uploads caused bottlenecks. Solution: Direct S3 uploads with presigned URLs. Result: 70% faster uploads and 90% reduction in server bandwidth.
Email Blocking APIs
Synchronous emails slowed order creation to 2-3 seconds. Solution: Async processing with Redis Streams. Result: Sub-500ms API responses with 99.9% delivery rate.
Dynamic Content Caching
Frequent price changes risked stale data. Solution: Tag-based invalidation with smart TTLs. Result: 85% cache hit rate with zero stale price incidents.
