Introduced a robust incident management process for the Search team that significantly boosted SLA from 95% to 99.9% across all online and offline workloads.

Transformed the hiring process by integrating a rigorous System Design stage, personally conducting over 70 interviews with a 1:20 interview-to-hire ratio, successfully filling 4 critical engineering positions.

Measurably improved observability across 5 engineering teams by unifying tooling based on the 4 Golden Signals principles, reducing defect detection time from hours to mere minutes.

Consistently achieved 75% of Key Results during my tenure as Staff Engineer, demonstrating strong leadership and execution in strategic initiative

Spearheaded the design and implementation of sophisticated offline and online Machine Learning Recommender Systems for Uzbekistan's largest e-commerce platform (5M MAU). This initiative enabled over 40 concurrent experiments, driving a remarkable 5%+ increase in Average Revenue Per User (ARPU) with an exceptional defect rate of less than 0.1% per release.

Designed and implemented a high-performance, 2-tier online Recommender System, achieving sub-5-second feature update latency. This system's performance was validated through A/B testing, matching the effectiveness of industry leaders like ByteDance's recommendations.

Orchestrated the Software Development Life Cycle (SDLC) for the Recommender System, streamlining the process to achieve a rapid 3-week Time-to-Market (TTM) for new model deployments.

Deployed 2 new speech-recognition models on time for the closed capture feature launch.

Fixed multiple bugs in the speech recognition service.

Integrated motion-blur feature as a wasm module to the video call platform.

Deployed dozens of ML models. Optimized inference latency and memory consumption of the image recognition model by 30%. Reduced in half time-to-market of features in the crucial business application by automating QA process and using CI/CD pipelines. Worked on HNSW-based distributed nearest neighbor vector search engine.
