A federal spending dashboard built on the USASpending.gov API. Originally a school project, that I took and revamped for my own personal learning. It features four interactive views: an overview tracking over $6T in budget data across 100+ agencies, a drill-down explorer with historical charts, quarterly trends, and a completely searchable awards dataset. Built to show how dense government data can be made navigable for non-technical stakeholders.

Primary developer on an internal dashboard at Tradebot, a quantitative trading firm. Architected a full-stack solution to process and visualize large-scale financial datasets, surfacing key trading metrics that previously required manual data pulling. Presented system performance directly to the executive leadership and trading floor teams.

Identified a gap in billing consistency and architected a drag-and-drop PDF scanning utility for the IT and Finance departments. Uses computer vision (OpenCV) to analyze ink-to-white surface ratios to automatically assign institutional billing tiers, eliminating manual verification.

Built and deployed an internal web application to automate device backup compliance tracking. Integrated CrashPlan's API for backup health monitoring and paired it with Zammad's ticketing API to auto-generate client notifications for disconnected devices, automating the entire follow-up loop.
