Dear Hiring Manager,
With a background in operations engineering and a passion for blockchain technology, I am excited about the opportunity to introduce myself to you.
Over the past two years, I have immersed myself in learning Ethereum and blockchain technology. I vividly remember the day I made my first transaction on the Ethereum mainnet after following the guidance from the book "Mastering Ethereum." Since then, I have continued to expand my knowledge and skills in this field.
I firmly believe that blockchain technology has the potential to revolutionize industries such as finance, software engineering, and real estate. My experience with Ethereum has reinforced my belief in the power of trustless protocols and the importance of security in blockchain systems.
I have taken proactive steps to enhance my skills in blockchain security, including completing the "Certified Smart Contract Auditor" course on Blockchain Council and studying resources such as "Ethernaut" and "Damn Vulnerable DeFi" from OpenZeppelin. I am committed to ongoing learning and development and am eager to apply my skills and knowledge to contribute to the success of Gelato.
I am confident that my background in operations engineering, my expertise in blockchain technology, and my dedication to security and reliability make me a strong candidate for the Site Reliability Engineer position. I am enthusiastic about the opportunity to discuss my qualifications further and learn more about the possibility of joining your team.
Thank you for reading my bio. I look forward to the opportunity to speak with you.
Sincerely,
Jerry Lin
