    Micro 1
    Mar 2024 - Jun 2025 (1 year 4 months)
    on Micro1, I collaborated on a project where we used outgoing webhooks to automate the evaluation process. After I ranked Claude's responses, the webhook would instantly push my ratings and feedback to a central database, triggering a separate pipeline that aggregated results across multiple annotators. This reduced manual data entry errors and accelerated the RLHF feedback loop. I also tested webhook retry logic and idempotency to ensure that duplicate events (due to network timeouts) wouldn't corrupt the dataset. This experience gave me a strong understanding of how webhooks enable seamless, event-driven communication between AI systems and external applications a skill I'm eager to bring to this role."
