As our business grew, we realized the need for a professional, modern, and highly functional corporate website to enhance our online presence and better serve our clients. We partnered with CompleteSoft to develop our website from the ground up. The project involved developing a corporate website. The CompleteSoft team worked in an outsourcing model, providing a dedicated team of front-end and back-end developers, QA engineers, and a project manager. We highly recommend CompleteSoft to any company looking for a professional and reliable software development partner.

The project involved building a real-time routing and geoanalytics module to support delivery route optimization and advanced mapping features. This included working with third-party mapping APIs, dynamic routing algorithms, and integrating live data such as traffic conditions, delivery windows, and vehicle constraints. Performance and reliability under load were critical. The collaboration was structured under an outsourcing model. CompleteSoft provided a cross-functional team that included backend developers, frontend engineers, QA specialists, and a dedicated project manager. They embedded smoothly into our Agile process, with two-week sprints, daily stand-ups, regular demos, and a transparent backlog managed in Jira and Confluence. Communication was handled via Slack and Zoom, making coordination smooth despite working across different locations.

The primary goal was to create a scalable web portal for customers to easily search and view property listings, while also developing a backend system for managing the vast amounts of data generated across the agency’s 300+ branches. Additionally, the solution needed to support agent-client communication, integrate property data across multiple locations, and centralize administrative functions. The web portal was designed with a powerful search engine, enabling users to filter listings by location, price, and other key criteria. CompleteSodt implemented features like property comparison, detailed image galleries, and direct contact forms to connect users with agents quickly. On the backend, the ERP/CRM system centralized property management across the agency’s branches.

We hired CompleteSoft to assist us in the development of the solution for one of our clients. Since they had expertise in logistics and supply chain, we entrusted them with backend development and additionally with design. They were involved in the development of a platform that leveraged historical data and predictive algorithms to generate accurate demand forecasts. The team also integrated Advanced risk assessment models, triggering alerts when potential risks exceeded safe levels. The platform was built on AWS cloud infrastructure and integrated with the client’s existing logistics systems through RESTful APIs. CompleteSoft managed the project with careful attention to detail, ensuring a structured process for research, design and development. Despite challenges, they address issues early and incorporate feedback promptly.

We would like to share our experience of working with CompleteSoft. We are very pleased with the implementation of the project to create an integrated system for managing electronic logistics documents. All integrated modules, including the registration system, document exchange, and the module of integration with the Transporeon system, were developed taking into account the best practices and technologies. This has greatly improved the client's operations and simplified the process of managing shipping documents. From the very beginning, the CompleteSoft team heard our objectives and goals and quickly proposed a solution. We worked with the team cohesively - all ideas and edits were discussed smoothly, professionally and completed on time.
