Senior Staff Software Engineer

Instagram

Founded and grew a team of machine learning and back-end systems engineers focused on identifying, validating, and operationalizing content quality hypotheses to create incremental long-term user value

-- developing annotation guidelines, scaled measurement, and analysis tooling
-- building content understanding ML models and near-realtime Human-in-the-Loop systems
-- rigorous A/B testing of novel treatments on ranking & retrieval systems to validate incrementality to consumption experience while measuring tradeoffs to top-line metrics, tracking metrics, and guardrails
-- deploy and scale product-aligned wins to ecosystem.

Tech Lead Engineering Manager (Content Quality Ranking)

Founded and led specialized ML/Systems team enhancing user safety & well-being across search and recommendations

-- detect, measure, model, and take action to
        * reduce policy-violating content prevalence
        * accelerate rapid response to incidents and developing situations
        * mitigate risky actor behaviors within complex regulatory landscape: adversarial, inauthentic, or information-related abuses including coordination attacks; promotion of highly sensitive, high risk topics; pattern of harmful content production/distribution

-- platform-ization of proven signals, online systems, and tooling to
        * streamline adoption of safety improvements across orgs and family-of-apps in a responsible way.
        * accelerate execution velocity across multiple orgs with near-real time feature engineering alongside a reliable parallel framework for safe, efficient rollout of signals and enforcement protocols to production recommender systems

-- drive product adoption of responsible ML/AI priorities:
        * scale algorithmic explainability and recourse capabilities
        * proactively identify and mitigate differences in outcomes attributable to algorithmic unfairness.
