Seif Aldeen Ashraf

I’m a Full-Stack Engineer specializing in TypeScript, Node.js, React, Next.js, and NestJS, with a strong focus on backend development and building reliable production systems.

I work across the entire stack, from designing databases and APIs to building user interfaces, deploying
applications, and maintaining them in production.

Tech Stack

• Backend: Node.js, NestJS, Express, TypeScript

• Frontend: React, Next.js, TypeScript, Tailwind CSS

• Databases: PostgreSQL, MySQL, MongoDB, Prisma

• Infrastructure: Docker, AWS, Linux, Nginx, CI/CD

• Other: Redis, REST APIs, Authentication, RBAC, Git/GitHub

\

What I can help with

• Building full-stack web applications

• Designing and developing REST APIs

• Backend architecture and database design

• SaaS platforms and multi-tenant applications

• Authentication and authorization systems

• Third-party API integrations

• Performance and database optimization

• Dockerizing and deploying applications

• Debugging and improving existing applications

• Building new features on existing codebases

I’ve worked on SaaS platforms, booking systems, e-commerce applications, business management tools, and custom web applications. I’m comfortable taking ownership of a feature or project from requirements and architecture through development, deployment, and ongoing maintenance.

I care about writing clean, maintainable code and building systems that are practical, reliable, and easy to extend.
