Projects

BIOMED-ERP

BMERP is a large-scale, business-focused ERP built for biomedical organizations. It combines inventory and serial-number traceability, multi-warehouse stock management, purchase and sales workflows, and maintenance ticketing into a single operational platform. The system replaces manual spreadsheets and fragmented tools with reliable, auditable processes, reducing reconciliation time, preventing stock losses, and improving compliance readiness. Features include bulk import/export workflows, background processing for long jobs, activity auditing, and integrations that make daily operations more predictable and less error-prone. Ideal for teams that need precise equipment tracking, clear audit trails, and dependable inventory operations at scale

ORDER-SPLIT

OrderSplit is a business-focused platform for managing shared food orders, cafeteria operations, and payment tracking in one unified system. It replaces spreadsheets, manual follow-ups, and disconnected tools with structured workflows for order creation, team participation, cost splitting, delivery tracking, notifications, and audit-friendly record keeping. Designed for company-scoped collaboration, it helps organizations run ordering and cafeteria processes more efficiently, reduce errors, improve accountability, and keep every transaction and status change visible from start to finish.

Beauty-Miss Store

Designed and implemented MVC-based E-commerce platform for skincare products and packages, featuring a cart, checkout system, real-time search, and secure authentication and authorization.

TebbPlus Platform (Healthcare)

Developed backend services for TebbPlus, a healthcare platform connecting clinics, patients, and medical suppliers, enabling appointment management, medical data handling, and secure user workflows.

QA-AGENT

AI Testing Agent (QA Agent) is a Laravel-based quality assurance platform built to turn SRS documents into structured, actionable test assets. It accepts PDF, DOCX, or TXT requirements files, extracts atomic requirements with AI, generates clarification questions and prioritized test cases, detects changes between SRS versions, and automatically creates bug reports when tests fail. With a Blade and Tailwind UI, multi-project workspace support, execution tracking, and export-ready reporting, it gives teams a more reliable way to move from requirements to verification with less manual effort and fewer missed details.
