e-End-to-End
provides software development
and systems integration
services to customers wishing to build, upgrade,and integrate
their information repositories and processes. We have helped
many clients integrate mainframe
systems with high-performance web-based
front-ends to automate business processes. We
have assisted large companies and state governments to upgrade
their IT infrastructure. We have built a solid reputation
as problem solvers in the most demanding and dynamic environments.
We can augment existing
staff with targeted expertise of our own, or
we can staff entire projects
and oversee all phases of the project from conception,
to design, to implementation, to testing, to production
and maintenance. We are a full-service enterprise software
organization.
We have worked with all types of organizations
from mid-size companies to large organizations
and can adapt our processes to fit ISO
9000 and CMMI
organizational quality processes.

to large company; each segment is described in more detailed
below. |

Mainframe Systems -
e-End-to-End has over
25 years experience with critical mainframe systems. We have
built mainframe gateways to address a wide range of technical
issues including high-speed data
connections, data integrity and two-phase commits
high-availability data
environments, and high-reliability
standards. We have developed applications for a variety of
mainframe operating systems including VSE,
MVS, OS/390,
etc. using IMS, CICS,
RPG and COBOL.
This development experience has given the knowledge necessary
to analyze existing custom applications, and formulate strategies
that provide effective, efficient interfaces to critical applications.

Midrange Server Systems -
e-End-to-End
has been involved with all the middleware technologies from
the beginning and we have developed expertise with systems
like .Net, Tuxedo, J2EE,
JMS,
MQSeries, CORBA,
and Web Services. We have
built many different kinds of mid-range systems, including
3-tier, message driven, request-response, and transactional
models. Our detailed experience with high-performance client-server
architectures involves load-balancing techniques, transparent
fail-over strategies, distributed transactional integrity,
and application and server clustering techniques.

Client Systems -
e-End-to-End
has expertise in human factors and interface
design principles to build user-friendly and intuitive front-ends
to the other systems. We have built windows-based interfaces
on all major client platforms including Microsoft,
Unix, HTML,
and Java. |
