Dear Hiring Manager,
I am excited to apply for the Full Stack Developer position at Northstar Apps. With 5+ years of experience building web applications end to end with React, TypeScript, and Node.js, I am interested in helping your team ship features that work well from the user interface down to the database. I enjoy owning features across the stack and writing code that is reliable, well tested, and easy to maintain as products grow.
In my current role at Brightline Software, I build React frontends and Node.js APIs, design PostgreSQL schemas, and improve performance on both the client and the server. Recently I led a feature that connected a new React dashboard to a redesigned REST API, which reduced page load times and cut error rates during peak traffic. I work closely with designers and product engineers to define clear API contracts, ship accessible interfaces, and roll out full-stack features safely.
What interests me about Northstar Apps is the opportunity to work on products where frontend quality, backend reliability, and performance all shape the user experience. I would be glad to contribute my experience with React, TypeScript, Node.js, databases, and testing to help your team ship complete features with confidence. I enjoy work where understanding the whole stack helps me make better decisions at every layer.
Sincerely,
Taylor Morgan

Yes, but only when they are relevant. Mention technologies like React, TypeScript, Node.js, SQL, or testing tools when they match the job description and your real experience.

Junior developers can focus on projects, internships, coursework, end-to-end features, and motivation to build complete products. The key is to stay specific and honest.
