Professional Experience – Career Journey
Designed and implemented multiple business-critical desktop and automation systems, defining
architecture, data models, and long-term maintainability strategies.
Key areas of work:
Utility tools (clipboard monitoring, file protection, task automation)
Educational tools (MCQs systems, math visualizations, signal simulations)
Business tools (clinic apps, school management, bookkeeping software)
Marketing automation (article spinners, link harvesters, proxy tools)
Custom development tools (code generators, script parsers)
As technology evolved, I migrated legacy VB6 systems to VB.NET, improving performance and
maintainability. I also learned Python specifically for automation, scripting, and data processing.
During this period, I expanded into:
Unicode and language processing tools (Arabic & Urdu)
Automation scripts (PTC platforms, repetitive workflow execution)
Web Scraping & Data Extraction (Downloading complete websites, Scraping data from websites & data
cleanup)
Early Visa Appointment Scripts (Detect & choose early visa appointment slots)
AI-Assisted Automation (Urdu OCR, speech-to-text and basic chatbot using pre-trained AI models)
Python became my tool of choice for rapid automation,
especially when speed and flexibility mattered more than UI.
Key Areas of Business System Architecture & Implementation:
Defined system architecture, security boundaries, and integration strategies for business-critical
web platforms
Education platforms (including nvaeducation.com with Android app)
Business websites and portals (Sian Enterprises, QAS International, and hundreds many more)
Accounting, and inventory systems (Businesses in Pakistan Rehman Traders, Shalimar Pumps and
more)
Invoicing systems (for Pakistan and Saudi Arabia Clients)
Organization Funds Management (for a business in Japan using Ceffu API)
E-Crime Portal (My Virtual University project developed in Asp.net)
VU Students Projects (Email Server, Forum, Namaz Tracker and more in PHP)
Web3 Projects (for UAE and Japan Clients, Crpyto trading bots. 100-125+ cryptocurrency
exchanges)
Islamic Tools (for Saif-ul-Uloom. Search Engine for Tafseer Tibyan-ul-Quran and
Tibyan-ul-Furqan.)
Daemon Apps (Jobs poll and schedular app for long running server side tasks.)
Security Experience & Business Solutions
Conducted security research to identify common vulnerabilities in legacy
and modern applications
Performed controlled SQL injection and input validation analysis in
permitted environments
Delivered remediation-focused vulnerability assessment reports to clients
Applied OWASP-aligned secure coding practices across business systems
I developed my own PHP framework and improving over time
While I was inspired with PHP Object Generator (POG) and upgraded it, later on studied
simple framework, CI-3, laravel and then developed my own framework.
It extended from POG to GRADE (Gegasoft Rapid Application Development Environment), having
laravel similar query builder and blade.
Gegasoft framework is focused on Security, Reusability, Performance and Business-oriented architecture.
