End-to-end real-time communication platform combining a Next.js web client with a scalable Go API. The product supports live messaging, typing presence, online/offline status, cursor-based message loading, file-ready object storage, and WebRTC signaling for voice/video calls.

• Built a high-performance Go backend with Gin, layered services/repositories, JWT authentication, bcrypt password hashing, and PostgreSQL data persistence.
• Implemented distributed WebSocket messaging with Redis Pub/Sub so the system can support multiple API instances and multi-device user sessions.
• Designed production-style local infrastructure with Docker Compose, Traefik reverse proxy, PostgreSQL, Redis, MinIO, Mailpit, migrations, seeding, and API documentation assets.
• Developed the Next.js frontend foundation with React 19, TypeScript, Tailwind CSS, Axios, Google OAuth integration, date-fns, and lucide-react UI icons.

Modern API documentation platform for product and backend teams. It can read and render API documents following the OpenAPI standard, then turns specs into a polished developer portal with authenticated access, searchable endpoint navigation, request/response details, code examples, and multi-format export for sharing documentation outside the app.

• Implemented OpenAPI-compatible document parsing so API definitions can be imported from standard YAML/JSON specs and rendered into readable endpoint documentation.
• Built a responsive documentation workspace with sidebar groups, endpoint search, method badges, schema tables, response examples, and syntax-highlighted code snippets.
• Implemented export flows for HTML, PDF, Swagger/OpenAPI JSON, and Word documents so teams can reuse the same source of truth across browsers, Postman, Swagger UI, and offline documents.
• Designed a clean login and protected docs experience with a dark authentication screen and a light documentation workspace optimized for reading long API references.
