Developed a web-based loyalty platform that allows companies to create custom rewards, analyze customer data, and engage their audience through push and email notifications. Designed server-side experiences for partners (businesses) to manage loyalty programs, access analytics, and choose from customizable subscription plans with monthly or annual billing. For customers, the platform allows them to seamlessly earn and redeem loyalty points at registered establishments.

Developed a solution that allows customers to report tickets through a .NET-based application. The ticket is securely sent to Azure Service Bus for processing in a highly secure, isolated environment. An agent then consumes the ticket, integrates it with Chatwoot using REST APIs and webhooks, and processes it internally. The issuer is notified of the ticket status via email, and QuestPDF is used to generate PDF summaries and reports for internal archiving.

Contributed to an e-learning platform designed to help students prepare for final exams. The platform integrated WordPress for e-commerce and payment processing, Azure B2C for single sign-on (SSO), and a backend based on .NET Web API. Once the core system was in place, I was responsible for improving key features such as course creation, quiz management, and event scheduling. The platform also supported advanced analytics and provided administrators with tools to efficiently manage users and content.

Helped transition a B2B-focused learning management system (LMS) from a single-tenant to a multi-tenant architecture. The platform allows companies to create and assign courses, track employee progress, and centralize knowledge. Features included SCORM 1.2 and 2004 support, course certification, and course creation automation via OpenAI. The solution also integrated Cloudflare for SaaS, allowing tenants to add custom domains. Azure Cloud and Infrastructure as Code (IaC - Terraform) were used to manage the production environment.

Contributed to the development of a web-based healthcare scheduling feature for an application designed for hospital coordinators and managers. The feature allowed users to create, manage, and validate employee schedules while ensuring compliance with specific regulations, such as break times and availability. The system automatically validated whether employees met required breaks, if days were available for scheduling, and helped ensure accurate, conflict-free scheduling for hospital staff. Worked on both backend (using .NET) and frontend (using React) to deliver a full-stack solution for this feature.

As a full-stack developer, I contributed to the development of a web-based platform for managing IoT devices in the eMobility and automotive sectors. The platform used the MQTT protocol (WS/TCP) and the EMQX broker for real-time communication with IoT devices, enabling seamless device monitoring and management. While the IoT devices themselves were managed by the hardware team, I worked closely with them to ensure successful end-to-end integration of the platform with the devices. The backend of the application was built using .NET 5/6, ASP.NET Core and gRPC, while the frontend was developed using React and Typescript, ensuring a responsive and user-friendly interface. The platform followed Clean Architecture principles for maintainability and scalability. I also integrated monitoring, logging, and alerting tools such as Graylog, Prometheus, and Grafana for proactive problem resolution and system visibility.

I developed an internal web application for employees working at reception desks, designed to manage guest visits and access card issuances. The application enabled reception staff to register guest visits, issue access cards, and authenticate users via Azure AD. I was responsible for the backend development using .NET 5/6 and ASP.NET Core, while also building the frontend with React, Typescript, and ant.design. Additionally, I integrated Swagger for API documentation.

Migrated on-prem infrastructure to Azure, automating the process with Terraform and Ansible. Used Docker Swarm and Portainer for container management, and ensured secure cloud connectivity with S2S VPN and Sophos Firewall.

Contributed to an internal web application designed to help employees track their work on various projects, create timesheets, and generate reports. The platform also supported synchronization with an external ERP system, allowing managers to view who was working on which projects in real-time. It streamlined project management and reporting, enhancing efficiency across the team. Frontend part was built using HTML, CSS, JS with server side rendered view using .NET.
