Backend Engineer · Open to Relocate

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

Started with Laravel in 2023 building my FYP and local projects. Since then I have shipped systems handling 500+ concurrent users — from university ERP migrations to multi-tenant SaaS platforms. I specialize in the messy middle: legacy migrations, database optimization, and API design that actually scales under production load.

Started with Laravel in 2023 shipping local projects. Now building systems that universities and enterprises run on.

I started with Laravel in 2023 — not in a classroom, but building my FYP and shipping local projects that actually had to work. That is where I learned that backend engineering is not about following tutorials; it is about debugging at 2 AM when something breaks in production and there is no one else to call. I learned by shipping, not watching.

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 am building productized Laravel applications and REST API infrastructure for clients who need systems that do not 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. Learned by shipping, not watching tutorials.
API Architecture
RESTful APIs with JWT auth, rate limiting, versioning, and SDK-level documentation. Built APIs consumed by thousands before I had a job title.
Database Performance
Query optimization, indexing strategy, schema design — MySQL and Oracle. Reduced report generation from 4+ min to 200ms on a live ERP.
Security-First Design
OWASP practices, auth layers, signed verification systems. Built cryptographic QR signing that reduced credential fraud verification to under 3 seconds.

Tools I use under production pressure, not in tutorials.

Every tool here has been debugged at 2 AM with a client waiting. I do not list things I have 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 have 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

Projects I have shipped and maintained.

University ERP Dashboard showing HR and payroll modules
Laravel MySQL Oracle Migration

University ERP — Oracle to Laravel Migration

Led backend migration of a decade-old Oracle Forms ERP to Laravel/MySQL. Handles HR, payroll, inventory, and academic records for 500+ concurrent users.

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 with QR code scanning interface
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 tracking system interface
Laravel RFID Inventory

RFID Inventory Management System

Built an RFID-based inventory tracking system during my early Laravel days. Synchronized real-time stock data with automated workflows — my first deep dive into hardware-software integration and data integrity under pressure.

Real-time Stock Sync
Major Error Reduction
Problems Solved
  • Manual inventory counting caused frequent stock discrepancies
  • Built RFID scanning integration with automatic database sync via Laravel queues
  • Implemented predictive reorder alerts to prevent stock-outs
Multi-tenant SaaS platform dashboard
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

From local projects 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.
