What they say about me

Working with Extino transformed our business workflow completely. We needed a complex Chrome extension that could integrate with our existing productivity suite, and their team delivered beyond our expectations. Not only was the extension flawlessly coded, but they also provided insights on UX improvements we hadn't considered. The extension now has over 50,000 users with a 4.8-star rating in the Chrome Web Store. Extino's technical expertise and attention to detail are unmatched.

Extino developed a price comparison extension for our e-commerce platform that has increased our conversion rates by 32%. Their team showed remarkable knowledge of the Chrome API and built a solution that was both lightweight and powerful. What impressed me most was how they handled the security aspects—our customers' data protection was clearly a priority for them. The ongoing support has been excellent as well.

As a solo developer looking to outsource part of my Chrome extension project, I was concerned about quality control and communication. Extino addressed all my concerns from our first meeting. Their developers integrated perfectly with my existing codebase, and their suggestions improved the extension's performance significantly. They were flexible with my budget constraints and delivered excellent value. I now consider them a long-term development partner.

Security was our primary concern when developing our password management extension. Extino's team demonstrated exceptional knowledge of Chrome's security architecture and implemented encryption protocols that exceeded our requirements. Their code review process was thorough, and they proactively identified and resolved potential vulnerabilities. Three years and several updates later, our extension maintains a perfect security record with over 200,000 users trusting it daily.

After two failed attempts with other developers, we found Extino. They understood our vision for a data collection extension immediately and turned our concept into reality within weeks. Their communication was transparent throughout the process, and they were exceptionally responsive to feedback. The extension they built has become central to our business model, and we've since hired them for three additional projects. I can't recommend Extino highly enough for Chrome extension development.
Our Chrome extension needed to work seamlessly with multiple CRMs while maintaining strict privacy standards. Extino not only met these technical challenges but also delivered the project two weeks ahead of schedule. The only reason for 4 stars instead of 5 is that we had some minor issues with the documentation, but their support team quickly addressed this. The extension now helps our team save approximately 15 hours per week on lead management tasks.

We approached Extino with a challenging project: creating a Chrome extension to improve web accessibility for visually impaired users. Their team showed genuine passion for the mission and contributed valuable insights beyond just coding. The extension needed to work across thousands of different websites, and their solution was elegant and robust. User feedback has been overwhelmingly positive, and the extension has received recognition from accessibility advocacy groups.

Extino developed our content curation extension on time and within budget. Their development process was well-structured, with regular updates and testing milestones. The extension's performance metrics have been excellent, with minimal memory usage even when processing large amounts of content. The only improvement I would suggest is more detailed user analytics in the initial release, though they've since added this feature in an update.
