Odoo Review from Navrina Singh
As a growing business in Australia, our internal systems had become difficult to manage. We partnered with SDLC CORP for Odoo development, and their team took the time to understand our workflows and bottlenecks. They automated repeated tasks, streamlined our processes, and kept communication clear at every step. This was not a one-time quick fix; it continues to improve how we run the business every day.

Mobile App Development Review from Robert Miller
I lost over $125,000 to developers who couldn't deliver so when I came to Dedicated Developers, I wasn't just looking for a dev shop, I was looking for a reason to trust again. They earned it fast. Their Idea To App Blueprint took everything scattered in my head and turned it into a clear, structured roadmap that actually made sense. Within six months, they delivered a sleek, fully functional MVP for our AI-powered homework assistant something a previous team couldn't pull off in over a year. What really set them apart was how early they brought in their ASO experts not as an afterthought, but from day one because they weren't just thinking about building an app, they were thinking about setting us up for a strong launch.Every deadline was met. Every question was answered. Every milestone felt like a shared win. As we approach launch, I can already see the difference a truly invested team makes the foundation is solid, the product is polished, and we're going to market with confidence we never had before. Dedicated Developers didn't treat this like a contract they treated it like a mission. After everything we went through before finding them, that meant everything. If you're serious about bringing your app idea to life and you're done gambling on the wrong team, this is the partnership that will change the trajectory of your product.
Mobile App Development Review from Ben Connors
As CEO of a relationship-focused mobile app company, I partnered with Dedicated Developers to build a dating platform centered on meaningful, long-term connections not casual swiping. I needed a true full-cycle partner, and they delivered. Before development began, they invested time in understanding the vision and created detailed product blueprints. They asked thoughtful questions, challenged assumptions, and scoped each phase carefully, ensuring smooth execution as the platform expanded. Their cross-functional team project manager, developer, UI/UX designer, QA specialist, and app store marketing expert consistently delivered milestones on time and handled complex feature requests with structure and clarity.Since launch, the app has achieved steady download growth, strong engagement and retention, and positive app store ratings a testament to the scalable, high-quality foundation they built. What stood out most was their true product-level ownership. They didn't just execute specs they contributed ideas, challenged assumptions, and helped refine decisions I hadn't fully considered. Their detailed blueprinting before each phase created clarity and saved significant time in execution. They treated the platform like their own product, and that mindset made a meaningful difference throughout a long, evolving engagement.
Mobile App Development Review from Akshath Goyal
As an advisor to a fintech startup, I've seen firsthand how Dedicated Developers operate at a level beyond typical vendors they truly act as product partners. They successfully architected and built a complex mobile platform combining social media and secure peer-to-peer payments, handling everything from blueprinting to post-launch optimization with strong ownership and technical depth. The result speaks for itself: over 1 million downloads, well received 5-star reviews, and a scalable, compliance-ready foundation. Their disciplined execution, transparency, and long-term thinking make them a valuable partner for any ambitious fintech venture.

RisingMax Inc.'s entire staff is supportive. They provide their customers with high-quality services and care about them. They take on tasks with a sense of responsibility, work hard, and meet deadlines. During the consultation, there was a constructive discussion.

I appreciated the initiative.

Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.
Web Design Review from Anonymous
Thanks to Infinum's website refresh, the client has seen an almost 100% improvement in their website's conversion rates. The team excels at project management, using the client's own proprietary tool and also Figma very well. Their proficiency in design, delivery, and client relations stands out.

UI/UX Design Review from ✨ Liz Pisney ✨
We recently partnered with Highland on research and prototypes for a new information architecture on a volunteer resources site for our Chapter leaders. Having over 3000 volunteers around the globe can introduce a lot of nuance and complexity to research and design processes. The team at Highland handled it all skillfully - focusing on how to deliver the most clarity and usability to our audience. 10 out of 10, I would recommend working with the Highland team!
Webflow Review from Lee Wiensch, CAE, CFRE
We had a great experience working with the team at Highland to develop a new website for the Thoracic Surgery Foundation, a charitable organization aimed at advancing heart and lung health for all. Highland worked with us to re-imagine a dated website with limited functionality, and developed a a gorgeous new site that beautifully reflects the vitality of the organization. We anticipate that our award applicants, donors, surgeons and grateful patients will be able to easily navigate the new site and have a much-improved user experience. Jeff Blanchard and his team were exceptionally good listeners, and worked hard to create solutions for our complicated awards program. They provided good training to our team throughout the process so that we have been able to keep things updated and easily make changes now that the site has launched. I am grateful for their patience and very quick turnaround as we juggled a new strategic plan and new branding, all at the time of the website creation. I have been continually impressed with the expertise and the innovation that Highland brings to a project like ours. It was a pleasure to launch this site -- on time and on budget -- with their excellent work and support.
