Senior Software EngineerScienceSoftMay 2025 - Current (1 year 6 months)• Owned backend feature delivery for an Internet discovery and threat-intel workflow, building Go services that normalized inbound data streams and exposed stable APIs for downstream detection jobs, improving end-to-end processing reliability.
• Hardened Kubernetes-deployed workloads by redesigning health checks, readiness gates, and graceful shutdown behavior in Kubernetes manifests, which reduced deployment-related timeouts and improved confidence during rolling updates.
• Improved SQL query performance in MySQL/MariaDB by profiling slow endpoints, adding targeted indexes, and rewriting join-heavy reports, which reduced average response latency and stabilized service behavior under burst traffic.
• Implemented secure authen- Senior Software EngineerEffectiveSoftMar 2021 - Apr 2025 (4 years 2 months)• Delivered backend services for cyber-related data ingestion and enrichment by building Go APIs and TypeScript-based orchestration endpoints, ensuring consistent data shapes across services and improving downstream detection accuracy.
• Stabilized production pipelines by redesigning asynchronous processing, adding retry budgets and idempotency keys, and improving message handling semantics to prevent duplicate or dropped records under failure conditions.
• Owned Kubernetes deployment configuration for multiple services using Terraform plus Kubernetes manifests, standardizing resource requests/limits and rollout strategies to reduce noisy alerts and deployment flakiness.
• Improved database performance for operational dashboa - Senior Full Stack EngineerSutter HealthJan 2017 - Mar 2021 (4 years 3 months)• Built and maintained end-to-end web application features using TypeScript and backend APIs in Node.js, connecting UI workflows to SQL-backed services and improving usability for healthcare operations staff.
• Refactored legacy backend endpoints to improve stability by addressing slow database queries in SQL (MySQL/MariaDB), adding indexing strategies and rewriting joins to reduce timeouts during peak usage windows.
• Delivered reliability improvements for integration points by hardening webhook handling and retry logic, ensuring idempotent processing and preventing duplicated records in downstream systems.
• Designed role-aware access patterns and secure session management across the application, including permission checks - VSoftware EngineerVolare SoftwareJul 2013 - Dec 2016 (3 years 6 months)• Contributed to full-stack feature development by implementing backend routes and UI components in TypeScript/JavaScript, wiring them to SQL-backed data models and validating behavior against real user workflows.
• Assisted with production support by investigating application errors reported by internal teams, reproducing issues locally, and collaborating on fixes that reduced repeat tickets and improved reliability.
• Worked on API and data-layer improvements by adding small query optimizations and correcting data mapping issues in MySQL/MariaDB, which improved report accuracy and reduced downstream confusion.
• Updated CI checks and basic deployment steps in Git-based pipelines, helping ensure changes were tested before re
