Baunfire designed and developed Zola's WordPress website from scratch. Initially, Zola shared its ideas, examples of preferences, and necessary content. They then collaborated through multiple drafts until finalizing the design. From there, Baunfire proceeded to build the site. The website allows customers to make reservations, view the menu, and access essential information, such as the restaurant's operation hours. (Verified via email)

Mobile App Development Review from Sony Tiwari
The whole Team at Calibrate have been great from beginning to end, and we're excited to have a partner as we continue to grow. Three words I would use to describe Calibrate are organized, insightful and collaborative. From the outset the scope of work was clearly defined, but they also showed great flexibility working through changes that arose. Faizan is terrific at running our regular meetings and keeping everyone up to date on progress. The team has a good balance at listening to your ideas but also guiding with their experience and expertise.Our project took longer than anticipated because of issues unearthed during the development, but Kevin and the team worked through it all with us. They went above and beyond to make sure we were satisfied with the final outcome.This is a talented team for sure, but their passion and ability to collaborate effectively is what really sets Calibrate apart.
eCommerce Development Review from Lorien Yonker
I partnered with Calibrate to develop a new eCommerce website, expertly integrating it with Shopify. Its guidance on software operation and website maintenance for future collections was invaluable. I valued the agency's patience and helpfulness in teaching me software intricacies and quick adaptability to changing project scopes. What set Calibrate apart was its attentive approach. Calibrate's small team was ideal for addressing my concerns proactively. While some may find it a drawback, I preferred the agency's primarily virtual meeting approach. (Verified via email)

Creative Services Review from Antonio Philantrope
Jigna was professional, patient, responsive, and highly collaborative throughout our CHOKOPAM branding project. She helped develop brochures, banners, event materials, tablecloth designs, and multiple refinements as our brand continued to evolve. She was always willing to incorporate feedback and work toward the best possible result. Communication was excellent, deadlines were respected, and the final deliverables were provided in print-ready formats. I would gladly work with her again and highly recommend her to anyone looking for a creative designer who is committed to client satisfaction.
