Example letter
Dear Sean, Lukas, and Stefan,
As a Munich-based software engineer and recent winner of Europe’s largest hackathon (START Hack 2025), I am highly motivated to join Mercura as a Fullstack Engineer. I thrive in high-intensity environments that demand rapid iteration and absolute ownership.
My technical profile directly aligns with your stack and product goals:
Core Stack: Extensive experience building production-grade applications using React, TypeScript, and Python.
AI & LLM Integration: Developed 'Interio,' an AI-driven full-stack platform integrating LLMs and automated image-processing pipelines.
End-to-End DevOps: Independently architected, deployed, and managed complex systems—including a 150,000-line e-commerce platform—using Docker, Cloudflare, and Coolify.
Having collaborated with cross-cultural clients and teams across Germany, Switzerland, and the Netherlands, I bring a global perspective and a high agency mindset. I am eager to work in-person at your Munich office to help automate back-office workflows for the physical world.
Thank you for your time and consideration.
Sincerely,
Enes Bala

How personalization works

Same question,
two very different answers.

Why should
we hire you?

Typical AI

I am a highly motivated professional with a proven track record of delivering results. I believe my skills and experience align perfectly with the requirements of this position. I am passionate about contributing to a dynamic, forward-thinking team — one that values innovation and collaboration. I am confident that my expertise — combined with my drive for excellence — would make me a strong addition to your organization.

Generic. Could be anyone.

Main Logo

I've spent three years coordinating product launches, usually with 12 to 15 people who reported to different managers. The timeline was never the hard part. Getting engineering and marketing to agree on “ready” was. I got good at settling that early so we don’t end up arguing two days before launch . Your posting says this role leads a rollout across distributed teams . I’ve done four of those , and the thing that made them work was fewer meetings, not more .

Specific. Grounded in your files and this job.

Underlined phrases in the Coverlttr draft mark the source: your CV, inspectable keywords, the job listing, and tone preferences.
