Featured Projects
TeaVision
ActiveAI-Powered Tea Harvest & Supply Chain Platform
Built a full-stack tea supply-chain platform combining AI-powered leaf quality grading with harvest, payroll, and end-to-end batch traceability. Developed a Go REST API with JWT authentication and role-based access control, integrating harvest operations, PostgreSQL data management, and ML inference. Fine-tuned MobileNetV3/EfficientNet CNN models for 3-class tea leaf quality classification and served real-time inference through FastAPI. Built a React Native field app for offline leaf-photo capture, AI grading, harvest-weight logging, and automatic synchronization; developed a Next.js dashboard for yield, quality, worker, and payroll analytics. Implemented batch-level traceability from field → factory → buyer, including stage-wise weight-loss tracking; containerized services with Docker and deployed on AWS with CI/CD.
GuideNow
ActiveRealtime Guide-Matching Platform
Built a cloud-deployed microservices platform that connects tourists with nearby, currently available guides in Sri Lanka for short tours, using Go backend services for live availability, location-based matching, and real-time chat, plus an AI service that turns natural-language requests into search filters, with CI/CD on AWS.
WhereMyPack
ActiveRealtime Order & Courier Tracking Platform
Built an event-driven Go microservices platform comprising Order, Inventory, Payment, Notification, and Tracking services using Apache Kafka. Implemented distributed transaction management and automated order rollback when inventory or payment operations fail. Developed real-time order status and courier location tracking via WebSocket, with Redis for high-speed status lookups and Pub/Sub messaging. Deployed the platform on AWS with automated CI/CD pipelines.
ShopStream
ActiveScalable E-commerce Platform with AI Search
Built a full-stack e-commerce platform with product catalog, cart, checkout, and order management, using Stripe payments with webhook-based confirmation and idempotent order handling to prevent duplicate charges. Implemented fast product search with Elasticsearch and an AI-powered natural-language search that converts queries into structured filters, cutting average search latency. Deployed on AWS (ECS, RDS, S3, CloudFront) with Docker and GitHub Actions CI/CD.
InvoiceFlow
ActiveInvoice Management System with Async OCR
Built an invoice management platform with an asynchronous document-processing pipeline for PDF/image invoices. Implemented Celery workers with Redis to process uploads in the background, perform OCR and structured data extraction, and persist results in PostgreSQL, with job status tracking and automatic retry handling. Developed REST APIs and a Next.js dashboard for invoice review, management, and reporting.
