I am Shah Shad, a Devops Engineer Backend & Automation.
My work focuses on building secure backend systems, automated infrastructure, and reliable network environments. I specialize in designing scalable architectures that combine DevOps practices, backend engineering, and server management. Beyond development, I actively manage Linux servers and network infrastructure, running a personal home-lab environment where I deploy services, test automation workflows, and experiment with real-world infrastructure setups. This hands-on environment allows me to design, monitor, and control servers while building practical solutions for modern applications. I don’t just write code — I build complete digital ecosystems that emphasize performance, security, scalability, and clean system design, from backend services to the infrastructure that powers them.
Designing scalable APIs, microservices, and high-performance backend systems.
Building automation tools and scripts to streamline infrastructure and operations.
Managing and optimizing Linux servers for stability, security, and performance.
Implementing CI/CD workflows, containerized deployments, and system automation.
Designing and managing network infrastructure, routing, and traffic monitoring systems.
Running personal server environments to test automation, networking, and infrastructure projects.
Designing and developing modular backend services that communicate through APIs, enabling scalable, independent, and maintainable system architecture.
Improving backend and server performance through tuning and monitoring.
Deploying and managing services using Docker for consistent and scalable environments.
Implementing access controls, firewall policies, and secure service configurations.
Configuring proxy systems to manage routing and backend services.

Developed a parental control network filtering system that restricts access to selected websites such as YouTube and Instagram for specific devices based on their IP address. The system allows administrators to define time-based usage limits, enabling access to certain platforms only for a specified duration (e.g., one hour) and automatically blocking them once the limit is reached. It operates at the network gateway level, ensuring centralized control over internet usage across connected devices.
Developed a financial tracking software for a mosque administration to manage member contributions and payment records. The system tracks paid and pending amounts for each member and maintains organized financial records. It includes an automated SMS notification system that sends confirmation messages when payments are received and monthly reminders to members with pending dues, improving transparency and ensuring timely contributions.
Developed a server-controlled SMS API service that allows applications to send SMS messages to specific phone numbers through a centralized API. The system manages and authenticates requests from client applications, enabling controlled and automated message delivery. It is designed to support free or low-cost SMS distribution, making it useful for notifications, alerts, and automated messaging services from connected applications. 📩⚙️
A centralized gateway server designed to manage and control network services across connected routers. The server functions as the main internet gateway, routing traffic through its filtering system to enforce parental control policies, such as blocking specific websites and applying time-based usage limits. It also hosts multiple internal services including a server profile management system, SMS API service, and warranty control APIs, allowing external applications to securely interact with the system. All network traffic passes through this gateway before reaching other routers or devices, enabling the server to monitor, filter, and control internet access across the entire network.
Developed a camera recording and backup system that captures footage from security cameras and securely stores recordings as backups through the Telegram API. The system automatically uploads recorded video clips to a Telegram channel or bot, enabling cloud-like storage, remote access, and quick retrieval of recordings. This approach ensures that surveillance data remains safely backed up and accessible from anywhere.
Developed a warranty analysis and tracking system that stores product warranty details and continuously monitors upcoming expiration dates. The system automatically analyzes stored records and sends email alerts before warranty expiry (e.g., two months in advance or on a specified reminder date), helping users take necessary action before the warranty period ends. This ensures better management of product warranties and prevents missing important expiry deadlines.
