Backend Developer
Built a production-ready RESTful API for a travel booking platform — covering tours, standalone activities, bookings, payments, reviews, guides, blogs, and user management across a 22-table MySQL schema.
Designed a unified polymorphic booking system for tours and activities, with server-side price calculation and Sequelize transactions using pessimistic locking (SELECT ... FOR UPDATE) to prevent double-booking of the last seats.
Implemented JWT authentication with HttpOnly cookies, 5-role RBAC with granular admin permissions and ownership checks, and an append-only audit log system that records who changed what, when, and why — protected by database triggers and exportable to CSV.
Built safe deletion flows that auto-cancel affected bookings, flag refunds, and notify customers by email; added Zod validation, Multer file uploads, Helmet, CORS, and rate limiting. Documented the API with Swagger/OpenAPI, set up CI with GitHub Actions, and deployed to Railway.

About Me
My name is Aghasalim Musayev
I started out on the frontend — building interfaces with JavaScript, React.js,
Redux Toolkit, Next.js (self-studied), Tailwind CSS, and Bootstrap. Over time I realized that
delivering a complete product means owning the full picture, so I expanded into
backend development as well.
Today I design and build applications end-to-end:
- RESTful APIs with Node.js, Express.js, and NestJS
- Data persistence with PostgreSQL, MySQL, Sequelize, and TypeORM
- Docker to keep environments consistent from development to production
I treat quality as a baseline, not an extra — JWT-based authentication,
Zod validation, centralized error handling, and Jest testing are things
I build in from the start.
In my daily workflow I rely on GitHub, Postman,
Figma, and VS Code. What drives me is the moment a complex problem
becomes a clean, reliable solution.
I’m open to frontend, backend, or full-stack roles where I can work on real products and keep
growing.
Feel free to reach out, I’m always happy to talk.
