EXPERIENCE
==========

Software Engineer — AllianceBernstein
Jun 2026 - Present
  * Migrated mission-critical legacy workloads—including MATLAB algorithms, R models, C# executables, and SSIS packages—into modular, containerized Python microservices deployed on Azure Kubernetes Service (AKS)
  * Collaborated on ask-fiqit, an internal LLM-powered platform assistant integrating across GitHub, Azure DevOps, Confluence, Slack, Control-M, Airflow, and Azure AI Search to accelerate quant developer workflows
  * Engineered automated ingestion pipelines to index internal code repositories and operational logs into Azure AI Search, enabling semantic code retrieval across engineering teams
  * Built a centralized SQL Server audit service to track user-specific roles and fine-grained database permissions, strengthening security governance and compliance
  * Automated the ServiceNow change request lifecycle, eliminating manual ticketing overhead and accelerating production deployment cadence
  * Leading the migration of mission-critical quant datasets, ETL pipelines, and scheduled batch jobs from legacy SQL Server instances to Snowflake to improve query throughput and scalability


Software Engineer — iPro Systems
Nov 2022 - Jun 2026
  * Developed and maintained backend services and APIs for a multi-tenant web application serving thousands of daily users, utilizing Python, FastAPI, PostgreSQL, and Vue.js
  * Refactored legacy ETL pipelines (MS Access, Pandas) into distributed Apache Spark jobs on AWS EMR, slashing execution times and saving thousands in monthly compute costs
  * Architected automated database migration tooling to onboard heterogeneous client schemas into the unified platform suite
  * Designed and optimized high-throughput relational schemas in PostgreSQL, ensuring sub-100ms API query latencies under peak concurrency
  * Built and maintained scheduled data pipelines using Spark SQL, Apache Airflow, and AWS EMR
