Selected work and portfolio

Midleo CORE - Connecting Systems. Simplifying Operations.

Midleo CORE is a centralized platform designed to organize, monitor, and manage middleware environments across distributed systems. It provides a unified view of middleware components, configurations, and operational status, helping teams maintain clarity and control over complex infrastructures.

The solution focuses on visibility, consistency, and operational efficiency, enabling structured management of middleware assets and supporting day-to-day operations through a web-based interface. Built with scalability and maintainability in mind, Midleo CORE serves as a foundation for reliable middleware observability and organization.

WebControl – Web-Based Home Automation Platform

WebControl is an early IoT solution designed to manage and monitor household systems through a centralized web interface. The project enables remote control of home components and automation workflows, allowing users to interact with their home environment securely over the internet.

The platform focuses on practical automation, system integration, and reliability, combining server-side logic with lightweight client interfaces. It demonstrates early adoption of web-driven IoT concepts, emphasizing extensibility, remote accessibility, and operational stability.

website of mathematical High School Lovech

Design and development of the official website for the Mathematical High School in Lovech (PMG Lovech), providing a centralized and accessible online presence for students, parents, and teachers. The site delivers structured academic information, announcements, school programs, and extracurricular activities through a clear and maintainable web interface.

Built with long-term sustainability in mind, the platform supports regular content updates, ensures accessibility, and presents institutional information in a professional and trustworthy manner suitable for an educational environment.

zapazi.bg - online booking platform

Developed more than 20 years ago, zapazi.bg was among the first fully functional online booking platforms in Bulgaria.
The system introduced digital reservations at a time when such services were not yet established locally, enabling businesses and customers to manage bookings online instead of relying on phone or in-person scheduling.
The platform was designed to handle appointment management, availability tracking, and customer interaction through a web interface, laying early foundations for scalable and user-centric booking solutions in the Bulgarian market.

Middleware Monitoring and Operational Support Solutions

Development and support of monitoring scripts and operational solutions for middleware environments, focused on visibility, reliability, and proactive issue detection. These solutions collect runtime metrics, service health information, and operational signals to support day-to-day middleware operations.

Built in alignment with DevOps and observability principles, the monitoring components help identify performance issues, detect failures early, and support stable, well-maintained middleware platforms in production environments.

DevOps-Driven Middleware Automation and Deployment Solutions

Development of automation solutions for deploying, operating, and maintaining middleware services and messaging infrastructures, built on core DevOps principles. This work includes the design of reusable automation scripts and Ansible-based workflows that standardize deployments, service management, and recovery processes across environments.

The solutions emphasize infrastructure as code, repeatability, and operational reliability, enabling faster deployments, reduced manual intervention, and consistent middleware operations in production systems.
