• Led architecture and delivery of an internal platform to replace ServiceNow org-wide as the sole technical lead, building Go services (go-zero, Kafka, MySQL, Redis) and aligning requirements across engineering, product, and operations teams.
• Designed and built a UI-heavy dashboard builder in React/TypeScript over the data sources migrated off ServiceNow, with extensive field-level validation and debounced input handling to keep large, interactive editing sessions responsive.
• Implemented client-side state rehydration so in-progress dashboards survive reloads, and subscribed the UI to a webhook-driven update channel that reflects server-side state changes in real time without manual refresh.
• Built automated sync of controls, findings, risks, and policies from the internal ticketing system into the GRC platform — 2,000+ controls in the first 5 months with zero manual re-entry — replacing the manual ServiceNow data entry the old process required (~30 hrs/month) and eliminating its transcription errors.

• Engineered end-to-end automated claims-processing workflows using Selenium-based web scraping, eliminating all manual data entry across multiple insurance provider portals.
• Implemented a Splunk observability framework with structured JSON logging and a standardized event taxonomy, cutting mean-time-to-detection from ~4 hours to under 20 minutes for production incidents.
• Reduced React application bundle sizes by up to 30% through systematic tree-shaking in Webpack build configurations, improving initial load time by ~1.2s on 3G connections.
• Built a DataGrid component from scratch with sorting, inline editing, drag-and-drop, and responsive design — adopted across multiple teams, materially improving development velocity.

• Built a tiled interactive-map platform as six services across five languages, splitting a Rust read path (PostGIS viewport queries, server-side clustering, tile cache) from a Java/Spring write path on a Kafka event bus.
• Added a Go gateway (JWT auth, routing, WebSocket realtime sync over Redis pub/sub), a Python tiling pipeline (image → XYZ pyramid → S3), and a Rails accounts/billing service.
• Shipped a React + MapLibre GL frontend projecting game-map pixel space onto Web Mercator for pixel-perfect tile/marker alignment; set up Protobuf contracts, path-filtered GitHub Actions CI, and Dockerized environments.

• Built an end-to-end CTR-prediction recommender on the 25M-row Taobao ad dataset, implementing a Deep Interest Network with target-attention pooling over user behavior sequences to model candidate-specific interest.
• Engineered a cross-language serving path — trained in PyTorch, exported to ONNX, served from a Go inference API via onnxruntime — with batched scoring that ranks an entire candidate set in a single forward pass.
