Federal Capability Statement

We have developed framework software (TSF) that executes on servers in a data center or the cloud (e.g., AWS) and we possess strong expertise in server-side software development projects (Java) - including code for parallel processing, multi-threading, scaling server code within and across servers, communication and security. Our framework greatly reduces project risk and accelerates delivery of projects. This combined with our consulting expertise ensures successful, on-time delivery of the most complex projects. Our framework enables connectivity from other systems, GUI front ends, web pages and software written in many languages (Python, C#, Swift [in addition to Java].) From a security perspective, our framework provides for the generation of ultra-secure 4096-bit public-private RSA keys and 2-way authenticated SSL connections with automated digital signing and storing of signed messages for non-repudiation capabilities -- ideal for contract execution, voting systems, etc.
