What People Say

Caleb was an excellent partner in building out a Stripe and Avalara integration in our software. The project created a huge lift for our accounting team and leveled up our compliance with sales tax laws that vary across each state. The integration required a significant amount of collaboration with our team, the Stripe and Avalara support teams. Caleb was able to complete the project successfully and on time. The results were extremely impactful in helping us to improve profitability as we were able to charge sales tax rather than absorb it into our rates and improved our accounting team's efficiency in reducing manhours to manually process the data. This project impacted a high volume of transactions which previously required a lot of data manipulation. Caleb was responsive to our needs and questions throughout the process!

Heather | Controller, ApplicantPro

This feature, which includes a mobile app and a real-time management dashboard, is a testament to his versatility as a developer. The dashboard system he created is intuitive and provides comprehensive insights, demonstrating his understanding of not just backend systems but also user-centric design.

Caleb possesses many qualities of an excellent software developer. His problem-solving skills are top-notch, as shown by his ability to tackle complex database and security issues. He is also a highly effective communicator, making complex technical concepts easy to understand for everyone on the team. His resourcefulness and proactive mindset allowed him to deliver ahead of schedule, consistently exceeding expectations.

Kevin | Coordinator, Emergency Response Communications
