Role: Senior Data Engineer
Location: Toronto, Ontario, Canada

## Professional Summary
Senior Data Engineer based in Toronto with 5+ years delivering ETL, lakehouse, analytics, and data platform systems across banking, insurance, and startup products. Much of my earlier delivery work was in Python, and over the last 1.5 years at Quantexa I expanded into Scala, Quantexa delivery, and certification-backed implementation work.

## Core Focus Areas
- ETL, orchestration, and data platform engineering across the tools a project demands
- System, solution, and data architecture across cloud data stacks
- Software engineering with data-engineering-adjacent tech stacks and delivery tooling
- Scala + Spark delivery built on the job at Quantexa, plus Quantexa Data Engineer certification
- Quantexa implementation support for teams already using licensed ER tooling
- CI/CD and deployment collaboration across Docker, Kubernetes, Jenkins, ArgoCD, and Azure DevOps workflows
- Experience across Azure with practical exposure to AWS and GCP
- Modern productivity-focused engineering practices

## Featured Projects
- IDF Ingestion Delivery Framework: Primary engineer for a centralized ingestion framework enabling the bank's cloud lakehouse teams to onboard sources faster with stronger governance.
- Quantexa Data Engineering Delivery: Hands-on delivery work at Quantexa across insurance and banking datasets, while ramping into Scala, learning the platform, and earning Quantexa Data Engineer certification.
- D365 High-Throughput ETL Platform: Designed ingestion for 100+ D365 F&O tables with strict delivery windows into Synapse/Delta Lake.
- Webfleet API to Power BI Delivery Pipeline: Built a scheduled ETL that extracts 15 API tables, applies cleansing, and publishes SharePoint CSV outputs for Power BI reporting.
