A full-stack SaaS application designed for photographers to manage clients, bookings, galleries, and business operations.
Highlights:
- Multi-tenant architecture
- Role-based authorization
- jOOQ-powered persistence layer
- PostgreSQL with advanced JSONB usage
- Complex relational querying using CTEs, array aggregation, and keyset pagination

Serverless employee management system built with AWS Lambda, API Gateway, and DynamoDB, including authentication and role-based access controls.
Data engineering and analytics project examining U.S. school district funding trends from 2010–2020 using Python, PostgreSQL, and Jupyter.
Before moving into software engineering, I spent several years in FinTech supporting payment processing operations and building Python automation used for reporting and operational workflows across partner financial institutions.
That experience gave me a strong appreciation for reliable systems, data quality, and the operational side of software.
Outside of software, most of my time goes toward photography and classical piano.
Photography has taken me throughout the mountains and dark skies of Southwest Colorado and ultimately inspired the SaaS platform I'm currently building.
On the music side, I enjoy studying classical piano and have worked on pieces by composers such as Chopin, Beethoven, Debussy, and Rachmaninoff.
