Work History
Support Engineer
Seraku
02.2021 - Current
- I am dedicated to providing support until the user is completely
satisfied. I don't just offer product knowledge. I also provide general IT knowledge when needed to ensure customers can use the product confidently. For complex technical issues, I have conducted investigations for up to a year, and I received a 5 out of 5 satisfaction rating in customer surveys. - I am good at troubleshooting and quickly solving complex technical issues. For example, I have set up necessary servers using Linux and created client applications or servers to build a testing environment when needed. By recreating the customer's issues, I can solve their problems faster. In busy months, I resolved over 60% of the team's inquiries by myself.
- I work closely with development and sales teams to conduct thorough investigations. It is important to clearly explain that further investigation requires support from other teams to gain their trust. Building a give and take relationship is also essential, not just asking for help. When the testing team was short-handed, I took on some of the testing tasks myself.
