Projects

What I've built

NutriLens

Problem

Manually logging every food item is tedious enough that most people abandon nutrition trackers within a few days — the friction is in the data entry, not the tracking itself.

Build

A Progressive Web App that cuts logging down to a barcode scan or a photo of a nutrition label. Barcode scans pull from Open Food Facts and USDA FoodData Central; for unscannable products, a vision LLM (Groq's Llama 4 Scout) reads a photographed label and converts the values into structured per-100g data automatically. Tracks macros, micronutrients, and daily goals, and installs like a native app via service worker caching.

Outcome

Turned food logging into a single scan or photo instead of manual search-and-entry.

Asset Management Automation - Siemens Energy

Problem

Off-boarded employees routinely kept company devices past their return window, with no systematic way to track or follow up at scale.

Build

Designed and built an automated reminder workflow in Power Automate, paired with custom HTML/CSS email templates, to flag and follow up on outstanding devices.

Outcome

Tracked 2,000+ non-compliant devices through the workflow, with an estimated ~$100K in savings from recovered and avoided device loss.

IT Ticket Data Visualization - Siemens Energy

Problem

IT leadership had no easy way to see resolution-time trends across tickets, and weekly/monthly reporting was compiled by hand.

Build

Developed interactive Power BI dashboards analyzing 15K+ IT tickets, with automated weekly and monthly reporting for leadership.

Outcome

Cut manual reporting effort by 60%+, improved SLA compliance, and accelerated ticket resolution.
