Volca is a B2B SaaS platform for service industry businesses (HVAC, plumbing, electrical) to manage and track technician payroll. I joined as a founding engineer in December 2025 right in the middle of a big pivot, where the product was shifting from a referral and spiff tracking app to a full payroll management platform. I worked on a small team of eight across the full stack on a React and React Native frontend with a Ruby on Rails backend, shipping new features, squashing bugs, and talking directly with clients to figure out what the product actually needed.

The work I did at Volca lives inside internal tools and dashboards that I can't share publicly. The sections below cover what I built while I was there.

One of the first big things I built was a user impersonation tool for the customer success team. Admins can pick any client business and user from a dropdown and instantly pull up their session on the frontend, which made support and debugging way faster. It took a decent amount of work on both ends to make sure it was properly secured and couldn't be misused.

I designed and built an automated email reporting system for payroll. It takes in payroll run data, dynamically generates an HTML/CSS email breaking down each technician's pay, and lets you schedule or immediately send it out to whoever needs it. Payroll is complicated, so a big part of this was actually sitting down with technician teams to figure out what they wanted to see in a pay summary and how to present it in a way that made sense to them.

I designed and built a payroll summary dashboard so business owners and admins could actually see what was happening in each payroll run. It has interactive charts and filterable tables showing the full earnings breakdown per technician: commissions, bonuses, deductions, the whole picture. I wireframed and prototyped the whole thing in Figma first before touching the codebase.
