Summary
👤
Senior🎓
Top SchoolRoberto Tambunan is an engineering leader with 10 years of experience building and scaling search and rewards systems across major Southeast Asian platforms, currently managing Grab Unlimited and VIP. He blends deep hands-on search engineering expertise—from Tokopedia’s core search and autocomplete to PayPay’s first search system—with product-minded squad leadership and operational ownership. Comfortable in high-throughput, data-driven environments, he has led cross-functional teams to deliver campaign management, point-tracking pipelines, and robust monitoring for large user bases. Although he now spends more time on strategy and people development than coding, his background in Golang, Elasticsearch, Redis and distributed systems keeps him grounded in technical trade-offs. Based in Jakarta, he’s known for turning complex search and rewards requirements into practical, scalable solutions that directly impact user experience.
