Where I’ve worked

1. Jan 2023 - PresentRemote

   Software Engineer II

   Circle Internet Financial

   Building the data infrastructure that powers blockchain ingestion at Circle. Shipped a multi-threaded ingestion framework, OpenTelemetry/Datadog observability, a custom Cosmos client for USDC reconciliation, and a refactor of the RDS pipeline that pushed data availability to 99%. Mentor junior engineers through weekly technology deep dives.

2. Jul 2021 - Dec 2022Remote

   Software Engineer

   Circle Internet Financial

   Shipped 70+ data pipelines into Snowflake with automated DDL generation, rolled out role-based access control across the warehouse, and built a ML gateway to AWS SageMaker that helped catch fraudulent card payments at $1M+/quarter scale.

3. Feb 2021 - Mar 2021Baltimore, MD

   Machine Learning Engineer Intern

   LibraX.ai

   Designed and shipped LibraX's ID-verification API in a month: a Flask service blending ML and fuzzy logic on Azure (API Management, Containers, Key Vaults, Table & Blob storage). Optimized the fuzzy search path for low latency and integrated Auth0 for custom JWT tokens.

4. Jan 2020 - May 2021Baltimore, MD

   Research Assistant

   University of Maryland, Baltimore County

   Thesis: "Lung Nodule Segmentation for Explainable AI Cancer Screening." Built a CT-scan analysis pipeline combining U-Net segmentation with graph-based nodule identification, integrated with an explainable classifier for malignancy and biomarker prediction on the LIDC dataset.
