With my experience in developing, testing, debugging, and improving warehouse back-end services at PT Tokopedia, I am confident that I can contribute to the growth and success of your company.

At PT Tokopedia, I played an integral role in the development of warehouse back-end services. My experience in Go, GraphQL, gRPC, Consul, Redis, Postgre SQL, and NSQ allowed me to effectively monitor service performance using tools such as Datagog, Prometheus, and Scalyr. I was also able to lead and manage weekly sync-ups across 5 teams and handle user experience problems and service issues, providing optimal solutions while creating documentation for project development.

Prior to my work at PT Tokopedia, I gained experience as an Associate Member at Sokrates System where I participated in developing and improving the front-end and back-end services of a multi-tenant School Information Management System Application website using tech stacks such as HTML, CSS, Angular, Laravel, and Postgre SQL. In addition, my work as a Student Mentor at Binus Student Learning Community allowed me to peer-to-peer mentor 10 struggling Computer Science students, where I was recognized as the ‘Best Mentor of Kemanggisan Campus’ for the odd semester of the 2019/2020 academic year.

My experiences in developing software systems, managing teams, and mentoring students have allowed me to develop a strong skill set that would be valuable to your team. I am confident in my ability to provide technical expertise, work effectively in a team, and deliver high-quality results.
