First Line Software was hired by Phoenix Energy Technologies, a company providing cloud-based IoT enterprise energy management solutions, to support their growth and need for scalable resources. The company required trustworthy senior engineers that could work with Agile methodologies and had good communication skills. First Line Software was brought on board to develop enhancements to web applications and database development and quality assurance. They were later assigned to build out a new product offering. The project was successful and the engagement is ongoing. The client appreciated First Line Software's flexibility to adapt to different products and technologies.

In another project, First Line Software worked with YAPILI, a micro-subscription messaging service for health advice, to design, build, and deploy their web-based solution as an Android app. The goal was to improve YAPILI’s usability on Android phones, the primary channel for online access in many of their African target markets. Despite the comprehensive and challenging nature of the software development task, First Line Software exceeded the requirements and managed to guide YAPILI toward the backend enhancements necessary to serve the new app. The client was impressed with First Line Software's professional discipline and responsiveness.

First Line Software was also hired by a consumer products company to build their e-commerce site. The company needed a solution that integrated well with their ERP/CRM and a platform that was best in class. First Line Software was chosen for its overall value in the RFP process. The team from First Line Software worked through development sprints to realize the client's vision for the new site. The client appreciated the team's expertise and the smooth progression of the project.
