Backend Engineer · Faisalabad, Pakistan

I build backend systems that turn complex data problems into reliable infrastructure.

3+ years building systems that handle 500+ concurrent users — from manufacturing RFID inventory tracking to university ERP migrations and multi-tenant SaaS platforms. I specialize in the messy middle: legacy migrations, database optimization, and API design that actually scales under production load.

Started in a manufacturing plant in Faisalabad. Now building systems that universities and factories run on.

My first engineering job was at Beacon Impex Falcon, a textile manufacturing company in Faisalabad. I wasn't writing web apps — I was engineering RFID-based inventory tracking, synchronizing stock data with Oracle OMS, and automating production workflows. That's where I learned that backend systems aren't about frameworks; they're about data integrity under pressure when a factory floor is waiting.

At The University of Faisalabad, I led the backend migration of a decade-old Oracle Forms ERP to Laravel/MySQL. The system handled HR, payroll, inventory, and academic records for 500+ concurrent users. I also built a cryptographically-signed QR document verification system that reduced credential fraud verification from days to under 3 seconds.

Now at TecBeck, I'm building productized Laravel applications and REST API infrastructure for clients who need systems that don't break under load. I specialize in the messy middle — legacy migrations, database optimization, and API design that actually scales.

Laravel at Scale
MVC, Eloquent ORM, Queues, Jobs, Events — production-tested with 500+ concurrent users across HR, payroll, and inventory modules.
API Architecture
RESTful APIs with JWT auth, rate limiting, versioning, and SDK-level documentation consumed by thousands of users.
Database Performance
Query optimization, indexing strategy, schema design — MySQL and Oracle. Reduced report generation from 4+ min to 200ms.
Security-First Design
OWASP practices, auth layers, signed verification systems, hardened application design. Cryptographic QR signing for credential verification.

Tools I use under production pressure, not in tutorials.

Every tool here has been debugged at 2 AM with a client waiting. I don't list things I've read about — I list things that have survived production load.

The core tools are what I reach for daily. The extended set is what I've used under real constraints — legacy Oracle migrations, multi-tenant SaaS isolation, queue worker failures at scale.

Core — Daily drivers
PHP 8.2 Laravel 10/11 MySQL 8 REST API Design Eloquent ORM Laravel Queues JWT Authentication Vue.js Blade Templates
Extended — Production-tested
Oracle DB Multi-Tenant SaaS Database Optimization PHPUnit Git / GitHub Postman Composer OWASP Security Linux CLI Bootstrap

University ERP Dashboard
Laravel MySQL Oracle Migration

University ERP — Oracle to Laravel Migration

Led backend migration of a decade-old Oracle Forms ERP to Laravel/MySQL for The University of Faisalabad. Handles HR, payroll, inventory, and academic records.

500+ Concurrent Users
200ms Report Gen (was 4min)
99.2% Uptime
Problems Solved
  • Oracle Forms legacy system had no API layer — built REST endpoints for mobile app integration
  • Payroll reports took 4+ minutes — optimized queries and added Redis caching, down to 200ms
  • No audit trail for HR changes — implemented event-sourced change logging
Document Verification System
Laravel Cryptography QR Codes

Cryptographic QR Document Verification

Built a document verification system using cryptographically-signed QR codes to prevent credential fraud. Reduced verification time from days to seconds.

<3s Verification Time
12K+ Documents Verified
0 Fraud Cases Post-Launch
Problems Solved
  • Credential fraud was rampant — fake degrees verified manually over days
  • Implemented RSA-signed QR codes with tamper detection
  • Built public verification portal with rate limiting to prevent abuse
RFID Inventory System
RFID Oracle Real-time Sync

RFID Manufacturing Inventory System

Engineered RFID-based inventory tracking for Beacon Impex Falcon textile manufacturing. Synchronized real-time stock data with Oracle OMS and automated production workflows.

Real-time Stock Sync
Significant Inventory Error Reduction
Problems Solved
  • Manual inventory counting caused 15% stock discrepancies monthly
  • Built RFID gate readers with automatic Oracle OMS sync
  • Reduced stock-out incidents through predictive reorder alerts
Multi-tenant SaaS Platform
SaaS Multi-tenant API

Multi-Tenant SaaS Platform — TecBeck

Building productized Laravel applications with true multi-tenant architecture. Each client gets isolated database schemas with shared application logic.

8 Active Tenants
<50ms Tenant Switch
Problems Solved
  • Clients needed isolated data without managing separate deployments
  • Implemented schema-per-tenant with middleware-based context switching
  • Built automated tenant provisioning and backup isolation
500+
Concurrent Users Supported
University ERP peak load
4min → 200ms
Report Generation Time
Oracle → Laravel migration
12K+
Documents Verified
QR credential system

RFID tracking system

From factory floors to university servers.

Every role taught me something different about what backend systems actually need to survive. Manufacturing taught me data integrity. University ERP taught me scale. TecBeck taught me productization.
