postgrid-node-client
|
Flexbase
|
| Highlights: |
PostGrid is a service that offers the ability to accept PDFs,
HTML, templates and physically print and email the documents
to recipients. As a bridge to the legal legacy world of printed
documents, it’s very helpful - but the straight REST endpoints
makes for difficult integrations. They also have an Address
lookup, verification, and autocomplete service, again with
just REST endpoints. This client makes it very easy for
Node/JS developers to work in a familiar system, while
leveraging all the powerful features
|
|
|
Design, Development, and Testing of the client.
Primary Tools: Node/JS, Typescript, Mac OS X.

|
creditsafe-node-client
|
Flexbase
|
| Highlights: |

in a familiar system, while leveraging all the powerful
features.

|
notarize-node-client
|
Flexbase
|
| Highlights: |
Notarize.com is an online notarization service, as well
as an eSigning authority. With the legal documents in
the Construction Industry’s accounts payable/accounts
receivable chain, this is essential for quick, fluid,
movement of documents - but the straight REST endpoints
makes for difficult integrations. This client makes it
very easy for Node/JS developers to work in a familiar
system, while leveraging all the powerful features
|
|
|
Design, Development, and Testing of the client.
Primary Tools: Node/JS, Typescript, Mac OS X.

|
|
|
|
Underdog
|
Guaranteed Rate
|
| Highlights: |
As part of a company-wide push to reduce the time to get to
Underwriting, a service needed to be built to pull loan fees from
commercial sources, predict values for taxes and other fees, and
create the multi-page application package that starts the loan
process. In addition to all the data collection and document
preparation, there were many business rules - by county - by
state that had to be considered. Finally, all this data had to
be served up to the system of record for the loan data
|
|
|
Design, Development, and Testing of the service/application with
security and a UI so that developers and the business users could
look at all parts of the application package - the pulled fees, the

|
Guaranteed Rate
|
| Highlights: |
Total Expert, a mortgage CRM, needed to have a service
that would send it all changes to the loan data, and all changes
to the contacts, so that it could accurately reflect the state
of the business. Additionally, a repository for all the contacts
that were in the CRM needed to be captured, and so a complete
mirror of the data in the CRM was needed.
|
|
|
Design, Development, and Testing of the service/application with
security and a UI so that developers and business users would
have access to the control of the data going up, and coming down
from the CRM.
Primary Tools: Clojure, Mac OS X, Linux (Ubuntu 14.04-16.04),

|
|
|
|
NS Toolkit
|
Guaranteed Rate
|
| Highlights: |
To enable small services to be written quickly with a
highly-reliable infrastructure, a clojure library needed to
be created, and maintained, which would allow all other
developers to simply access resources (AWS, SQS, databases,
other RESTful services) in idiomatic clojure, and therefore
focus on the creation of unique business-logic and value.
|
|
|
Design, Development, and Testing of the library including
testing and research into internal and external services.
Primary Tools: Clojure, Mac OS X, Linux (Ubuntu 14.04-16.04),

|
Bartender
|
Centro
|
| Highlights: |
The large number of Ad Servers and sources of external data
to Centro got to be a significant load on the existing system,
and so a new service was spun up that would be focused on doing
just this one task, but in a more universal way so that
additional services could easily be added, and the data sent
to back-end stores.
|
|
|
Design, Development, and Testing of the system to access multiple
external sources of client data, handle fail-overs, retries, and
storage so that systems could refer to this data internally, as
opposed to hitting external sources.
Primary Tools: Clojure, Mac OS X, Linux (CentOS 5), Kafka,
Redis, Postgres, Functional design and coding
|
|
|
|
Unified-Click Stream, Disruption Detector, Finch Analytics
|
Groupon
|
| Highlights: |
The volume of data flowing through systems at Groupon got to
the point that nightly jobs to aggregate, analyze, and report
on data were simply too little too late, and a new generation
of tools and systems were needed. Real-time - based on the
output of all client-facing systems, fast, reliable, and
immediately available to all business interests in the
organization. These projects are the first in that next
generation of analytics.
|
|
|
Design, Development, and Testing of the system to process all
real-time log data from all client-facing internal systems,
create a unified, coherent data stream from this, calculate and
store all results for historical retrieval, and serve this data
to several internal groups.

Dark Magic
|
Groupon
|
| Highlights: |
As Quantum LeadŐs need for ever more advanced and complex processing
of the incoming demand grew, it was decided to break out that part
of Quantum Lead into a separate project - Dark Magic. It was also
decided that several new technologies: clojure, Storm, and Hadoop
would be used in this project to establish their capabilities in
production systems.
|
|
|
Design, Development, and Testing of the system to process demand
data from internal systems, merchant data from Salesforce.com, store
all calculations for historical retrieval, and serve this demand into
Quantum Lead.
Primary Tools: Clojure, Mac OS X, Linux (RHEL 5), Hadoop, Storm,
Functional design and coding
|
|
|
|
Quantum Lead
|
Groupon
|
| Highlights: |
Having captured the buying habits of Groupon's customers
as well as the geographical data they provide, as well
as the merchant deals and capabilities, it is a natural
fit to mate up the anticipated demand with the available
merchants to make the sales representatives far more efficient
than guessing what would benefit the merchant as well as the
customer. QuantumLead is a system that does this matching
and feeds the best leads back into the system for a nice,
tight, feedback loop.
|
|
|
Design, Development, and Testing of the system to extract
demand data from internal systems, merchant data from
Salesforce.com and write updated info to Salesforce.

DataBusII
|
PEAK6
|
| Highlights: |

meant a new kind of system needed to be designed and
built to allow for automatic A/B arbitration, preferred
side flipping in case of line outage, and downstream
conflation for slow clients, so that fast clients got
every message, and slow clients didnŐt overload, or
over-burden the upstream systems

consuming clients as well as slow, and adding the what
if scenario capability not present in current systems
|
|
|
Design, Development, and Testing of a pricing (greek) engine
taking embedded DataBusII ticker plants, event-driven
processing with lockless data structures to enable minimal
delays in processing for both high-speed clients and slower,
on-demand, clients. To minimize additional components, a
request/response what if capability was added to give clients
additional capabilities through the same interface.
Primary Tools: GCC (C++), Linux (Ubuntu 10), ZeroMQ, MMD,
OOA&D.
|
|
|
|
MMD
|
PEAK6
|
| Highlights: |
SOA is fine, but service location, load-balancing, and
API mismatches creates difficulties in growing an
infrastructure of many diverse services. MMD, or Magic
Middle Dude, is PEAK6Ős attempt at solving these issues.
Using distributed erlang, services connect to a local
MMD node that replicates the services they publish,
connects them to services on other nodes, balances the
load of all services, and provides API conversion for
websocket clients.
