Top SchoolBambang Sinaga is a Technical Lead with 10 years of experience building scalable, object-oriented platforms and guiding teams through architecture, OKRs, and operational improvements.

Comfortable across Ruby on Rails, search/ETL, and backend APIs, he favors pragmatic solutions to complex problems and keeps dependencies up to date. Based in North Sumatra, Indonesia, he’s as strong in system-level thinking as in day-to-day delivery and continuous improvement.
