Real partnerships. Honest feedback. See why organisations across Australia trust Cloud Downunder to design, build, and support their digital products.

A special shout-out to Sam, who was incredibly professional, knowledgeable, and dedicated. Sam took the time to understand my needs and expectations for a future Mercedes-Benz App and went above and beyond. His attention to detail and commitment is evident in every aspect of his work. In addition to his technical expertise, it is clear that Sam is genuinely invested in the success of his clients. If you're looking for a reliable, talented, and customer-focused app development company, look no further than AppGurus.

AppGurus built a platform to manage the driver compliance paperwork and fault reporting system for heavy vehicles. It could automatically review all paperwork, sending notifications when there were issues. AppGurus showed genuine passion for the project, giving invaluable technical insights.

AppGurus managed the project well despite the changes in the scope and design. The team constantly communicated through messaging apps at every key deliverable. They also collaborated through in-person meetings.

AppGurus ensured a smooth workflow through frequent communication and prompt customer support — they were always quick to respond to any queries or concerns. The team was also proactive in terms of sharing helpful ideas. They loved my concept and understood my target market really well.

AppGurus was helpful, timely, and efficient at collaborating via Basecamp. Moreover, they embraced the client's vision very well and were communicative, responsive, and solutions-oriented. They were very quick to embrace my vision, providing me with endless solutions for anything I asked for.

AppGurus offered strong interpersonal relationships that optimized the development process. The apps have remained in the top positions of the education genre in the Apple Store. I appreciate AppGurus' loyalty and understanding. We've formed a bond and trust with each other, and we respect each other's opinions.

We came to AppGurus with an idea and extremely basic wireframe of our concept. They provided priceless industry knowledge, transparency and understanding as part of the design and construction process. As a startup with no app development or programming knowledge, the experience of AppGurus turned our idea into a polished, fully functioning product. The continuing support we have received after completion of our app has been exceptional.

I moved to AppGurus in 2019 after using another company for a number of years and not being satisfied with the quality of work. The change was the best thing I ever did for my app. AppGurus actually listened to exactly what I wanted out of my app and nothing was too hard for them - as well as their pricing was attractive. I would happily recommend AppGurus to anyone whether they are wanting a development done from scratch or already have a product and they are not happy with their current service. I'm very excited about the future of my app knowing I have the backing of AppGurus if I need anything.

Where to begin? We can all conceive that app development is highly specialized. Client expectations have to be managed especially where projects take on a life of their own, creating options that could never have been envisaged at the start. In our case, subject to certain parameters, AppGurus became a quasi partner in fulfilling the dreams we had of our project. The integration of their ideas into our project was priceless. This does not happen in normal business dealings. Big Thumbs Up AppGurus.

I approached the AppGurus to transform my Homeworthy Inspection System into a mobile app. They guided me through the entire process and made Homeworthy a robust platform by utilising my vision and industry experience. Many businesses and individuals now conduct their inspection services using Homeworthy and the numbers are growing. I personally have saved 2 hours per day on inspection reports, by simply using the Homeworthy app. It's a fast and reliable experience.

We never felt that we were dealing with sales people, but rather with a team that had a deep technical understanding. AppGurus built an app to improve communication between the client and their customers. They also integrated an AI element to make custom recommendations to users.

Working with the AppGurus was very professional and streamlined. They took my vague descriptions of what I wanted and turned them into something real and functional. There was a lot of extra guidance which has been quite valuable in shaping Eater Meter to what it is today. I highly recommend AppGurus for any sort of web-app related development.

These guys are great and easy to work with. Their patience and service has been amazing considering we come from a non tech background. Highly recommend them.

AppGurus provided the outcome what I was expecting. I just shared my idea with their team which I wanted to publish in the market and they guided me and made this product in a very efficient way. My apps are available on stores and I am really happy with the service they provided.

App Gurus delivered a fully-optimized product that went beyond the project's original scope, much to the client's delight. The team was highly communicative, and internal stakeholders were particularly impressed with the vendor's team dynamic, work ethic, and solutions-based approach.

The app has earned a significant amount of downloads since its launch. Thus far, the platform has satisfied expectations and matches the original vision. App Gurus is dedicated to the project, ensuring they’re approachable and timely in the case of issues.

App Gurus listened to client needs and ensured any technical issues were resolved quickly. The cost was higher than expected, and there was a slight staffing mishap early on, but user responses have been good.

App Gurus has delivered a functional and easy-to-use app in a timely manner. The team has ensured stellar communication and efficiently addressed the project requirements. Their receptiveness, design competencies, and innovative approach are key elements of their work.

Boasting a strong understanding of the client's needs and goals, allowing them to confidently deliver a solution that matched. The reliable team utilized Basecamp to manage the project and collaborate effectively with the client throughout. Their high-quality design and development work stood out.

Thanks to App Gurus' efforts, the client was able to establish a clear scope for a web-based solution while tailoring the apps for their target audience. The app also allowed businesses to sign up and manage their menus. Overall, the team was easy to work with and dedicated to the project.

Decided on App Gurus to save time and effort. They understood what I wanted, and I loved their enthusiasm and energy from the beginning and felt that they were the right people to work with. They provided various options and a quote that was unbeatable which was a contributing factor to my decision to work with them within a specific budget. They guided me through the processes step-by-step and I received some great advice along the way.

App Gurus has successfully delivered a fully functional website and mobile app, satisfying the client's needs. The team utilizes their in-depth knowledge to deliver quality outputs and provide helpful advice. The partners interact through email and messaging apps. Their knowledge is impressive.

Love the design of my app and very happy with the progress. Sam and his developers have gone the extra mile to give me a great product. Looking forward to launching this summer!!

I have been very happy to work with App Gurus on my project. It was a complex project, and it took time to refine it to conform to my ideas. They approached it with patience and professionalism, and I am definitely pleased with the final outcome.

My company engaged App Gurus to create a new portal linking several off the shelf software items using API. Not only was App Gurus affordable, their work was completed within timely and correctly. I would have no hesitation in recommending Sam and App Gurus for your next project.

When I was looking for a company to take on my app, most companies wanted to charge me more than my budget just to create a proof of concept. App Gurus came up with a plausible solution on how to make my idea work at our first meeting. This was my first app development project and the team walked me through the process to not only build the app, but also assisted with all things Apple and getting it on to the App Store. The result is a very professional and funky product.

Despite setting high expectations, App Gurus managed to exceed them. I had a unique job that required some out of the box thinking and App Gurus was up to the challenge. Their ongoing support was excellent - actively seeking my feedback, being patient with all my requests and prudently addressing them. I’d highly recommend their services if you’re looking for a job to be done right.

Apache Cassandra consulting covers cluster architecture and data modelling, migrations from other databases or DataStax Enterprise, performance tuning, multi-datacentre replication, and ongoing managed operations. Most Australian businesses start with a health check or maturity assessment before scoping a larger project.

Cost depends on cluster size and scope. A fixed-price Cassandra health check is the usual starting point, followed by a scoped migration or tuning project, or an ongoing managed services retainer. We quote after a short discovery call once we understand your current setup.

A single-cluster migration typically takes two to six weeks, depending on data volume, downtime tolerance and how many applications read from the database. Multi-datacentre or multi-application migrations are usually rolled out in phases to reduce risk.

Apache Cassandra is the open-source database at the core of both. DataStax Enterprise adds commercial features such as advanced security, search and analytics on top, along with licensing costs. Many businesses migrate from DSE to open-source Cassandra to cut licensing spend once they no longer need those extra features.

Cassandra suits workloads with heavy write volume, time-series or event data, and a need for linear scalability across multiple regions without a single point of failure — think IoT telemetry, messaging, product catalogues or user activity feeds. If your data is highly relational with complex joins and lower write volume, a relational database is usually still the better fit.

Both. We run consulting engagements for architecture, migration and tuning work, and we offer ongoing Cassandra managed services — monitoring, patching, repairs and incident response — for teams that want day-to-day operations handled without hiring a dedicated DBA.

Yes. We design and implement active-active and active-passive replication across regions and cloud providers, including AWS, Azure and Google Cloud, so a single datacentre or region outage doesn't take your application offline.

Yes, including K8ssandra-based deployments. We handle cluster design, storage configuration, scaling and operational tuning for Cassandra running on Kubernetes, alongside traditional VM or bare-metal deployments.

The most common causes are a data model that doesn't match query patterns, compaction strategy mismatched to the workload, tombstone build-up, hot partitions and undersized JVM heap settings. Our performance tuning engagements start by diagnosing which of these is actually driving the slowdown, rather than assuming you need more hardware.

Yes. We work with businesses across Australia — Sydney, Melbourne, Brisbane, Perth and remote teams — with delivery and support scheduled to Australian business hours regardless of location.
