Building practical systems across cloud security, data, and machine learning

Portfolio LinkedIn GitHub Medium Cisco Community Email Public Repos

Overview

I recently completed my M.S. in Computer Engineering at New York University, where I also worked as a Data Analyst and Salesforce Admin at the NYU K12 STEM Education Center.

My work sits where analytics, backend engineering, and applied ML meet. I enjoy building systems that are useful in the real world: tools that catch risky cloud defaults, workflows that surface fraud signals, dashboards that help people make decisions, and open-source fixes that improve platform behavior.

I care most about engineering that is practical, explainable, and production-minded.

Right Now

  • Cloud security tooling for finding risky defaults before deployment
  • ML-backed data systems for fraud detection, scoring, and decision support
  • Open-source engineering across workflow and finance platforms
  • Dashboards and operational analytics that turn raw data into action

Featured Work

DefaultRisk

A Terraform plan scanner that detects security-relevant omitted defaults before they quietly reach production.

  • Focuses on what was not configured, not just what was explicitly misconfigured
  • Produces console, JSON, and SARIF outputs
  • Built for CI workflows and practical security review

Stack: Python, Terraform, CLI, AWS security rules

Repository

Fraud Shield

An end-to-end fraud detection system for large-scale credit card transaction analysis.

  • Handles class imbalance and model comparison
  • Serves predictions through an application workflow
  • Exposes risk signals through a dashboard experience

Stack: PySpark, MLlib, Flask, Pandas, React

Repository

Library and Event Booking Management System

A full-stack application covering books, events, study rooms, invoices, and role-based access.

  • Supports both admin and user workflows
  • Includes dashboard views and booking flows
  • Shows product thinking beyond notebooks and one-off analysis

Stack: React, JavaScript, SQL, MySQL

Repository

Open Source Contributions

I like contributing where the problem is concrete and the fix improves actual developer workflows.

  • Apache Airflow: task runner, Helm chart, and CLI-related fixes
  • Apache Fineract: localization and validation improvements
  • Public PRs focused on behavior, reliability, and usability

View Contributions

Open Source and Community

Beyond repositories, I also spend time helping in public technical communities.

  • Contributed fixes and improvements to Apache Airflow
  • Contributed validation and localization updates to Apache Fineract
  • Shared accepted solutions on Cisco Community in routing, switching, and network security discussions

I like shipping work that is useful, clear, and built to hold up outside the notebook.
