Software Engineering Case Studies

Centralized Inventory & Multi-Branch Warehouse ERP

The Challenge: A regional distributor operating across Delhi NCR managed 4 physical warehouses using fragmented spreadsheets, causing frequent inventory discrepancies, stockouts, and delayed dispatches.

Architectural Solution: NextBytes architected a custom web-based ERP featuring real-time inventory ledger syncing, barcode dispatch scanners, role-based access control (RBAC), and automated purchase order generation.

Tech Stack: PHP (Laravel 10), MySQL, Redis Caching, Bootstrap 5, AWS EC2 & S3.

Outcome: 100% elimination of double-booked stock and 45% faster order turnaround time.

HIPAA-Compliant Patient Portal & Telehealth Consultation Platform

The Challenge: A healthcare provider suffered from manual telephone appointment bookings, high patient no-show rates, and no secure mechanism for remote video consultations.

Architectural Solution: Engineered a responsive web & mobile portal with automated slot scheduling, WebRTC peer-to-peer encrypted video consultations, digital prescription generation, and automated WhatsApp appointment reminders.

Tech Stack: Node.js, React.js, WebRTC, PostgreSQL, Docker, Twilio & Razorpay APIs.

Outcome: 65% reduction in appointment no-shows and seamless remote consultations.

Automated B2B Wholesale Marketplace & Quotation Engine

The Challenge: An industrial parts supplier processed high-volume RFQs (Requests for Quote) through email threads, taking up to 48 hours per quote and limiting wholesale sales capacity.

Architectural Solution: Developed a custom B2B e-commerce platform with dynamic tier-based pricing calculators, automated PDF quotation rendering, credit limit validation, and live buyer-seller messaging.

Tech Stack: PHP, MySQL, Redis, RESTful API endpoints, Linux VPS.

Outcome: RFQ processing time slashed from 48 hours to under 20 minutes.

Real-Time Fleet Dispatch & Route Telemetry Application

The Challenge: An urban distribution fleet operating across Delhi, Noida, and Gurugram struggled with blind delivery status tracking, inefficient manual routing, and high fuel burn.

Architectural Solution: Built a cross-platform driver mobile app paired with a central dispatcher dashboard featuring live GPS plotting, proof-of-delivery photo capture, digital signatures, and automated trip analytics.

Tech Stack: Flutter (iOS & Android), Python (FastAPI), TimescaleDB, WebSockets, OpenStreetMap.

Outcome: 100% live route visibility and significant reduction in transit delays.
