Engineering Case Studies & System Architecture

System Architecture Highlights:

• 01POS Checkout & Validation Engine: Cashier scans items; system validates customer NTN/STRN, computes tiered sales tax rates, and generates an internal cryptographically signed draft.
• 02Asynchronous BullMQ & Redis Ingestion: Invoices are pushed into a persistent FIFO queue with exponential backoff retry. Even if FBR's gateway drops, the transaction is safely committed in under 20ms.
• 03Cryptographic FBR Gateway Bridge: A dedicated gateway microservice validates Annexure-C JSON schemas, transmits to FBR, and receives the official FBR Invoice Number (USIN).

System Architecture Highlights:

• 01High-Performance Modern Web Frontend: Sub-second product catalog with dynamic package sliders, currency toggle (PKR/USD), and real-time domain availability lookup.
• 02Local & Global Payment Gateway Webhooks: Automated webhook listeners verify instantaneous PKR mobile wallet and debit/credit card payments with multi-signature verification.
• 03WHMCS Orchestration & Virtualization Bridge: Upon webhook validation, the provisioning engine triggers KVM hypervisors to allocate AMD EPYC vCPUs, RAM, and PCIe 5.0 NVMe storage in 45 seconds.

System Architecture Highlights:

• 01Pre-Rendered Departmental & Faculty Showcase: All departmental pages, course catalogs, and faculty profiles are statically pre-rendered for instant sub-0.4s load times globally.
• 02High-Concurrency Online Admissions Engine: Streamlined applicant onboarding with document upload verification, fee voucher generation, and automated merit list calculation.
• 03Redis-Cached Academic Transcript Lookup: Result queries are cached in memory, preventing database lockouts when 15,000+ students check grades concurrently.

System Architecture Highlights:

• 01High-Fidelity Visual Showroom: High-resolution fabric textures and garment construction details compressed with modern codecs to load in sub-0.8s worldwide.
• 02Compliance & Factory Audit Center: Direct access for overseas compliance officers to download authenticated ethical audit certificates and sustainable energy disclosures.
• 03Automated RFQ & Tech-Pack Ingestion: International buyers upload apparel tech packs and receive automated milestone confirmations, notifying export directors instantly.

System Architecture Highlights:

• 01Dimensional Signage Scope Builder: Prospective clients select sign type (3D illuminated letters, lightboxes, pylon signs), input dimensions, upload architectural drawings, and specify installation sites.
• 02Interactive Architectural Portfolio: Over 500 completed fabrication projects categorized by material and industry, enabling instant visual proof for corporate clients.
• 03Automated Estimator Dispatch: Inquiries are structured into standardized job specs and forwarded to fabrication estimators within seconds of submission.
