Experience
– 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
- Migrating mission-critical quant datasets, ETL pipelines, and scheduled batch jobs from legacy SQL Server instances to Snowflake to improve query throughput and scalability
–
- 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
- Configured CI/CD pipelines with automated unit, integration, and security testing using AWS CodeBuild and CodePipeline
- Diagnosed and resolved critical production incidents across backend APIs, query bottlenecks, and ETL orchestration workflows
–
- Authored engineering specifications for a $55M blast furnace modernization project, coordinating technical requirements and vendor evaluations
- Supervised on-site contractors through installations, heavy maintenance, and scheduled facility turnarounds under strict safety standards
- Partnered with equipment vendors and multidisciplinary engineering teams to procure industrial components and ensure specification compliance
–
- Reduced unplanned plant downtime by conducting root cause failure analyses and engineering a retrofit lubrication system that extended equipment lifespan
- Designed mechanical components and industrial assemblies in 3D CAD to support plant reliability improvements and facility retrofits
- Conducted technical and financial feasibility studies to evaluate proposed capital modernization projects
–
- Drafted custom conveyor and material handling assemblies using 3D CAD software
- Performed engineering calculations for drive motor sizing, structural load distribution, and belt tensioning
–
- Calibrated and maintained laboratory instrumentation including tensile testing machines, wind tunnels, and CNC machinery
- Supported faculty and undergraduate researchers in conducting material characterization experiments and processing stress-strain test data
