Pediatric Clinic Platform (Medisite)

Developed backend services for a pediatric clinic platform using Django REST Framework. Implemented user registration, JWT authentication, appointment scheduling, blog and content management, and role-based access control for Doctor, Editor, and Patient roles. Added a business rule limiting each patient to one active appointment. Migrated the project database to PostgreSQL, containerized the application with Docker, and deployed it on my own Linux server. Configured Nginx as a reverse proxy, including selective proxy-bypass rules for routes that required direct upstream handling, and managed production DNS and HTTPS access.

Pulse — Private Messenger

Built Pulse, a self-hosted private messenger with Django, Channels, ASGI, WebSockets, PostgreSQL, Redis, and Docker. The web application supports authenticated one-to-one and admin-managed group conversations, persistent history, read receipts, typing indicators, replies, voice messages, private attachments, profiles, and an operations dashboard. An Android companion app uses the same web experience with native file handling and periodic notification checks. The service is hosted at pulsetalk.ir; Android background alerts are periodic rather than instant push.

Telegram Archive Viewer

Developed a self-hosted Telegram archive viewer that parses Telegram Desktop HTML exports, stores normalized message data in SQLite, and provides fast full-text search using FTS5. Implemented authenticated media serving, reply navigation, filtering, and a responsive chat-style UI. Containerized the application with Docker and added automated tests, CI, Dependabot, semantic versioned releases, and GHCR publishing through GitHub Actions, while keeping personal exports and local database files outside the public repository.

TaskFlow

Developing a task and project management web application using ASP.NET Core MVC and Entity Framework Core. Implemented full CRUD operations for tasks and projects, form validation, service-layer architecture, dependency injection, and a one-to-many relationship between projects and tasks with cascade deletion. The application uses SQLite for persistence and follows a structured MVC approach with ViewModels and separation of application logic from controllers.

Self-Hosted Server & Deployment Infrastructure

Built and managed a self-hosted deployment environment for multiple personal web applications on a Linux server. Configured Docker-based services, reverse proxies, DNS records, CDN integration, HTTPS routing, firewall rules, and service isolation. Worked with Nginx, Nginx Proxy Manager, and Arcane to operate and troubleshoot containerized applications, route multiple domains and subdomains, and handle practical deployment issues across the application, network, and infrastructure layers.

Arista Exchange Platform

Rebuilding Arista Exchange from a static marketing page into a remittance service platform with ASP.NET Core MVC on .NET 10, PostgreSQL, Entity Framework Core, and Docker. The modular monolith separates Domain, Application, Infrastructure, Web, and background Worker projects. The codebase includes public service and content pages, account and verification flows, customer and admin areas, KYC and transfer workflows, CMS administration, an outbox-based notification worker, automated tests, and technical SEO. The former static website remains archived in the repository.
