Сопроводительное письмо

I am writing to express my strong interest in the Senior/Staff Software Engineer position at FLYR. With over 7 years of experience in backend development and a deep proficiency in Java and microservices architecture, I am drawn to FLYR’s mission of eliminating legacy constraints in the travel industry. My background in building high-load, high-uptime services aligns perfectly with the requirements of your Order Management team.

In my previous roles, I have successfully designed and optimized complex database structures using PostgreSQL and managed scalable systems within Kubernetes environments. I am particularly excited about the opportunity to work with Google Spanner and the prospect of transitioning towards Golang in the mid-to-long term. As a seasoned engineer, I am also prepared to take on the mentorship and technical leadership responsibilities associated with the Staff level, fostering an environment of engineering excellence.

I am impressed by FLYR's commitment to innovation and its inclusive culture. I am confident that my technical expertise in RESTful API design, CI/CD automation, and cloud-native development will allow me to make immediate contributions to your product roadmap. Thank you for considering my application.
