System Case Studies
Real problems. Purpose-built systems. Measurable outcomes — not just code.
AI Digital Avatar System
Human-like AI that handles customers at scale
Problem
Customer service kiosks needed 24/7 human-quality interaction without the cost of staffing.
Solution
Developed real-time interactive avatar system with LLM personality, speech-to-text, and streaming voice response over cloud.
Outcomes
- Handled 40% of standard customer inquiries without human intervention
- Real-time streaming response under 1s latency
- Deployed in kiosk environments with full voice interaction
Tech Stack
Billing Management System
Automated billing engine for SaaS and subscription businesses
Problem
SaaS and service businesses managed billing manually — no recurring payment engine, fragmented gateways, and no unified financial dashboard.
Solution
Built an automated billing platform with subscription package management, sales catalogues, secure multi-gateway checkout (eGHL, Gkash, ipay88, RazerPay), and a full financial transaction dashboard.
Outcomes
- Supports 10k+ customer accounts with automated recurring billing
- Integrated multiple payment gateways with full order lifecycle tracking
- Reduced billing operations overhead with automated invoicing and white-label checkout
Tech Stack
IoT Data Center Monitoring
Eyes across every rack, sensor, and floor zone
Problem
Data center teams had no real-time visibility into environmental conditions — temperature spikes and equipment failures went undetected.
Solution
Integrated IoT sensors across infrastructure with a live dashboard including interactive floor plan visualisations and alert pipelines.
Outcomes
- Real-time visibility across all infrastructure zones
- Reduced incident response time with instant alerting
- Interactive floor plan with sensor overlays
Tech Stack
Wireless AP Controller & OpenWrt Firmware
Fleet management for thousands of edge devices
Problem
Deploying and managing hundreds of wireless access points across sites required manual configuration and had no central control.
Solution
Built custom OpenWrt firmware for Qualcomm platforms plus a centralised controller for provisioning, SNMP monitoring, and remote management.
Outcomes
- Large-scale fleet provisioning from a single dashboard
- Remote firmware updates and configuration pushes
- Improved deployment speed and network reliability
Tech Stack
Manufacturing ERP (OMS / MES / WMS)
Factory-floor intelligence from order to shipment
Problem
Manufacturing operations ran on spreadsheets and whiteboards — no real-time shopfloor tracking, inventory visibility, or order orchestration.
Solution
Built a modular ERP covering order management, MES shopfloor tracking, and WMS warehouse operations with event-driven architecture.
Outcomes
- Reduced manual data entry by 80%
- Real-time shopfloor visibility and production tracking
- Increased inventory accuracy with automated WMS
