      Software Development Review from Lori Feld Oakley

      Our Services organization is scaling quickly and we urgently needed a custom software application to automate our workflows, without breaking our annual budget. CodeStringers was the perfect fit, supporting us from ideation through go-live and everything in between. They innovated, hit their deadlines and released an amazingly high quality application that decreases our internal costs and improves our reputation with our customers. It would not have happened without CodeStringers.

      Enterprise Review from Christian Schraga

      CodeStringers is the perfect outsourcer to call If you have a solid software business idea but don’t know exactly how to bring it to life. They have both a top-notch development team as well as an executive staff with expertise in marketing, finance, and general business acumen. So they can not only build a product for you but they can make sure that the product you want to build is likely to succeed in the marketplace.

      Small Businesses Website Development Review from Kris Meyer

      Austin rebuilt our website from the ground up and helped turn Bespoke Tint & PPF into one of the top tint brands in Bellevue. The work started with a full redesign of our website, including branding, copywriting, conversion improvements, mobile optimization, and development. The new site immediately performed better and generated more leads after launch. After the website launch, we continued working together on SEO, AI search optimization, paid advertising support, analytics, A/B testing, and ongoing marketing strategy. He also helped improve our review visibility, local search presence, and overall positioning online. What started as a website project became an ongoing growth partnership focused on increasing traffic, leads, and customer acquisition.

      Rob has been a huge help for us! From website design, to SEO and Google ads. He’s been a reliable addition to our team. Communication is top notch and he goes above and beyond for his clients. The CRM in his package has also transformed the way we communicate with our clients. More bookings, more conversations. It’s that simple.

      The dashboard Perimattic delivered is minimal, well-structured, and very user-friendly. Small touches like the layout, flow, and clarity of controls make a big difference. Great work by Gaurav and his team.
