What I'm looking for

I'm looking to build accessible, performant web and mobile products, collaborate closely with product and design, and contribute across frontend and backend workflows.

At ION Solar, I build backend services and APIs for high-volume scheduling and sales workflows across web and mobile products. I helped deliver a major 2.0 release, improving UI flows, usability, and visual consistency.

I’ve implemented constraint-based scheduling that accounts for geographic distance, travel time, availability, and operational rules, along with automated appointment assignment based on deal likelihood and representative performance. On Proposalist and The Grid, I’ve built React, React Native, Ruby on Rails, and PostgreSQL features for proposal management, lead tracking, appointments, and field-sales workflows.

I bring a frontend-leaning full-stack approach, collaborating closely with product and design to create accessible, performant, and maintainable user experiences.
