While most of the industry manages software development the wrong way (like investing millions of € over 3 years of development to realize only then that the market is not interested in their product), we strive to build the least complex yet satisfactory and stable solution to deliver something fast on the market. Our real strength is our project management skills: we know how to discern the real value for the users of an application thanks to our understanding of Lean Manufacturing and Agile Principles. This helps us to organize the development of the features by priority for the end users. This way, we build a solution 100% ready to be used to fulfill the promise made to the users within the defined budget and without compromising the software quality. We reject bureaucratic processes adding no value to the work (SAFe, Scrum...) for the end users and prefer direct interactions with them. Our proper network of trustworthy professional freelancers makes also a difference! How do we work? It is simple: we define a reasonable budget together, and our team works on developing the fastest solution yet stable, that delivers the expected essential service. Only then and if the budget is not burnt down would we build a more advanced solution or add non-essential features. This is the only way to respect your budget. We always leave the solution we develop in a usable/releasable state even if a more advanced solution is still in development. We want quick results and fast feedback on which to build a product that makes a real impact. All of this is thanks to our technical practices (such as continuous delivery, TDD, automated testing, and trunk-based development...). EVERY DAY WE RELEASE NEW FEATURES FOR THE END USERS AND OUR CUSTOMERS. AND YOUR APPLICATION IS ALWAYS IN A USABLE STATE! What do we technically do? We support you in the development and maintenance of single-page applications for the frontend, and backend services (REST, RPC, MQTT, Web-socket, Kafka...), setting up a continuous deployment and integration pipeline passing the code through batteries of tests. We also manage product development integrally. See you soon!
We develop your entire solution: from UI design, integration, and development, to backend development, automated testing, and deployment.
Technically, we can do the following: - front-end development of Single Page Applications via Server Side Rendering and Client Side Rendering; - REST and JSON APIs and GraphQL, or real-time Pub/Sub via WebSocket on the backend; - ensure code quality with the development of the automated tests (unit, integration, visual, interactive, application, system and performance); - automate application deployment by setting up Continuous Delivery pipelines, leveraging containerization via Docker, and versioning solutions from Gitlab and GitHub
What are our prices? We charge usually a €10,4k subscription per month. We require a minimum down payment of 50% before getting to work. Also, if we define a budget of €50k to develop your idea, we will maybe not need to use it completely. We will not ask you to pay it in one settlement. Rather, we keep charging for the work of the upcoming month until the application is developed as agreed, and hopefully, the €50k will not be completely consumed.
What we do not accept: "I want you to commit to the time it will take for you to develop the features listed". No, we do not estimate precisely how much time we'll spend on a task. Not out of fear of risk, but out of professionalism. Programming is not a productive activity (where tasks look the same), but a creative activity dependent on several non-deterministic factors that we can't get to know beforehand. ESTIMATES ARE NOT A RELIABLE PREDICTION TOOL, so we found a way to work without them: WE DON'T CREATE A FEATURE IN ITS MOST ADVANCED VISION IN THE FIRST PLACE, WE SIMPLIFY OR PROPOSE INTELLIGENT, TIME-SAVING ALTERNATIVES SO THAT WE RATHER UPDATES every day. We rely on daily deliveries to our customers and end users to get feedback on those simple features as soon as possible. We find out about their adjustments later. This allows a lot of adjustments at no extra charge for our customers.
