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 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 had to work. That is where I learned that backend engineering is about debugging at 2 AM when production breaks and there is no one else to call. I learned by shipping.

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 build 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 scales.

Laravel at Scale
MVC, Eloquent ORM, Queues, Jobs, Events — production-tested with 500+ concurrent users.
API Architecture
RESTful APIs with JWT auth, rate limiting, versioning, and SDK-level documentation.
Database Performance
Query optimization, indexing strategy, schema design — MySQL and Oracle. Reduced reports from 4+ min to 200ms.
Security-First Design
OWASP practices, auth layers, signed verification systems. Built cryptographic QR signing with tamper detection.

Tools I use under production pressure, not in tutorials.

Core tools I use daily, plus extended tools I have deployed 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.

04 Projects · 2023—2025
University ERP Dashboard — HR management, payroll overview, and MySQL database status panels
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.

500+ Concurrent Users
200ms Reports (was 4min)
99.2% Uptime
Problems Solved
  • Oracle Forms had no API layer — built REST endpoints for mobile integration
  • Payroll reports took 4+ minutes — optimized queries + Redis caching to 200ms
  • No audit trail — implemented event-sourced change logging
QR Document Verification System — cryptographically signed certificate with verification status panel
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
Problems Solved
  • Credential fraud — fake degrees verified manually over days
  • Implemented RSA-signed QR codes with tamper detection
  • Built public verification portal with rate limiting
RFID Inventory Management Dashboard — real-time stock levels, barcode scanner, and warehouse floor plan
Laravel RFID Inventory

RFID Inventory Management System

Built an RFID-based inventory tracking system. Synchronized real-time stock data with automated workflows — my first hardware-software integration.

Real-time Stock Sync
Major Error Reduction
Problems Solved
  • Manual inventory counting caused frequent stock discrepancies
  • Built RFID scanning integration with automatic DB sync via Laravel queues
  • Implemented predictive reorder alerts to prevent stock-outs
Multi-Tenant SaaS Platform — tenant switcher, database schema diagram, and API request metrics
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 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

Multi-Tenant SaaS Architecture

Why I chose schema-per-tenant over row-level isolation, how middleware handles context switching, and keeping tenant switch under 50ms.

From local projects to university servers.

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