Worked on the Netflix/mantis repository to enhance backend scheduling and improve system reliability. Developed a scheduling feature in Java using the actor model, introducing conditional resubmission for worker allocations stuck in an accepted state, which increased resource utilization and reduced manual intervention. Addressed a critical bug by refining heartbeat handling logic during leader elections, distinguishing between freshly launched workers and those missing heartbeats to prevent unnecessary resubmissions. Employed CI/CD practices and thorough testing to validate changes, resulting in more predictable delivery timelines and greater operational stability. The work demonstrated depth in backend development, scheduling algorithms, and robust system design.
