Example Cover Letter: Full Stack Developer

Dear LaunchPad Labs Team, I'm excited to apply for the Full Stack Developer role. With expertise spanning React on the frontend and Node.js/Python on the backend, I thrive in startup environments where I can own features end-to-end and ship fast. At my last company, I single-handedly built and launched a SaaS billing portal from zero to production in 6 weeks — integrating Stripe, building a React dashboard, and writing the API in Express with a Postgres database. The feature generated $120k ARR in its first quarter. LaunchPad's focus on helping early-stage startups build and scale quickly speaks directly to what I do best. I move fast without cutting corners, communicate proactively, and genuinely enjoy the full problem — from database schema to pixel alignment. I'd love to join a team that ships real products to real customers. Let's talk. Best, Sam Rivera
