Windows Server Domain Setup + GPO Automation + Backup & Recovery

Windows Server 2022 Active Directory (AD DS) DNS Group Policy (GPO) Acronis Cyber Protect

Overview

Designed and implemented a modern enterprise-grade IT infrastructure using Windows Server 2022 to centralize identity management, strengthen network security, and automate administrative operations. The solution leveraged Active Directory Domain Services (AD DS) integrated with DNS for seamless authentication and name resolution across the organization.

A structured Organizational Unit (OU) hierarchy was created to organize departments efficiently and enable precise policy application. Group Policy Objects (GPOs) were implemented to standardize configurations, enforce security policies, and reduce manual IT effort.

Additionally, a reliable backup and disaster recovery strategy was implemented using Acronis Cyber Protect Cloud, ensuring data protection, quick recovery, and business continuity.

Fortinet 60F SD-WAN Deployment

FortiGate 60F SD-WAN VLAN

Project Overview

Engineered and deployed a highly resilient, enterprise-grade network architecture utilizing a Fortinet FortiGate 60F firewall. This project was centered on transforming the organization's network into a highly available, secure, and optimized infrastructure capable of supporting seamless corporate operations and mitigating modern cyber threats.

Key Technical Implementations:

  • SD-WAN & High Availability: Integrated dual ISP links (Jio and Spectra) into a robust SD-WAN architecture. Configured intelligent load balancing and automated failover routing to guarantee zero-downtime connectivity and optimize bandwidth for mission-critical applications.
  • Strategic Network Segmentation: Designed and deployed isolated VLANs to separate corporate departments. This logical segmentation prevents broadcast storms, significantly minimizes the internal attack surface, and enables precise, department-level bandwidth allocation.
  • Next-Generation Firewall (NGFW): Implemented comprehensive security protocols including strict IPv4 traffic rules, advanced intrusion prevention (IPS), deep application control, and stringent web filtering to actively block external threats and unauthorized access.
  • Centralized Management & Monitoring: Leveraged the FortiOS dashboard to establish real-time visibility into the security fabric, active network sessions, and overall system health, allowing for rapid incident response and proactive maintenance.

The successful deployment of this infrastructure significantly reduced network latency, eliminated single points of failure, and established a fortified, future-proof security perimeter for the organization.

Job Resume | Automated ATS-Friendly Builder

React / Vite Tailwind CSS Lovable AI Supabase

Overview

Job Resume is a high-performance web application designed to democratize the resume-building process. It transforms the daunting task of resume formatting into a seamless, automated experience. By focusing on a "content-first" philosophy, the app allows users to input their professional history through a structured interface while the engine handles complex layout logic and ATS (Applicant Tracking System) optimization.

Key Technical Features

  • Dynamic Data Rendering: Built a reactive input system that syncs user data instantly with a live document preview, ensuring "what you see is what you get."
  • Professional Template Engine: Developed a collection of minimalist, high-conversion templates designed specifically to pass through modern recruitment software filters.
  • Intuitive UX/UI Flow: Engineered a multi-step form architecture that reduces "blank page syndrome" by breaking the resume down into digestible sections.
  • One-Click Export: Integrated a robust PDF generation engine that preserves typography and layout integrity across all devices and screen sizes.
  • Mobile-First Architecture: Optimized the entire build for mobile responsiveness, enabling users to make last-minute edits to their professional profiles directly from their smartphones.

Impact & Problem Solved

Traditional word processors often lead to formatting errors and broken layouts when adding new content. Job Resume solves this by decoupling content from design. The result is a tool that saves users hours of manual adjustment, providing a polished, recruitment-ready document in under 10 minutes.
