Achievements at Barclays

Lead the tech team to pass a very critical transition period on 2010:

Before and after I joined Barclays first 4 weeks, all original developers in the tech team

left. At the same time, with limited resource and tight deadline, we had to add new

features to commission management system in order to satisfy one big client

(Millennium LLC)’s immediate requirement which is very critical to win or lose the

contract. I took the challenge and successfully completed the project on time, which

made us win this big client and gain the chance to rebuild the tech team in following

years.

Real time pricing engine: One of the major tasks of commission management is to calculate soft commission

based on various trade scenarios. To process the soft trades in real time makes

Barclays at leading position in soft dollar business and help us win more clients. The old

pricing schema is build using database stored procedures which has huge gaps to

process complex trade scenarios automatically and also makes adding and changing

the pricing rule difficult and time consuming. By carefully analyzing the business

requirements and different technologies, we choose Drool, a state of art rule engine, as

our pricing engine framework and combine with Solace as messenger system and

Coherence as cache to build a comprehensive commission pricing rule engine. This

project was a great success and makes Barclays the first broker dealer to process soft

dollar business T+0.

Here is my manager’s comment:

“Wei has been crucial to the success of the pricing engine. The system was very complex and it couldn't

have been delivered successfully without Wei's dedication and attention to details. The business has

been very happy with the results and I am confident the product will be effective well into the future

because of it's well thought out design which Wei has been a major contributor to.”

The pricing engine allows our business to provide clients with flexible pricing on various

trade scenarios as well as accurately haircut the soft commissions and this is one of the

most important factors clients consider when choosing a CSA broker partner. The new

pricing engine is well architected and a lot of new features are added after initial

deployment to production. Multiple layers of pricing rules can be defined for a client and

a great, uniformed performance is realized even with constantly added new rules.

Risk calculation is used to be manual work, since the business needs to apply complex

formula to recalculate the soft commission and then create journal to adjust financial

balance. We successfully build the risk model in pricing engine and realize real-time risk

calculation and put Barclays Commission Management ahead of peer firms.

Redesign and build new CAS Reconciliation Engine: Old CAS reconciliation engine was out of state and dragged the productivity of

commission management daily operation and being constantly complained by business

about accuracy, data integrity and efficiency. I had a multi-phase project to redesign it

and built a state of art reconciliation engine to automate the reconciliation process with

minimum human intervention. The reconciliation process that the business executes on

a monthly basis for many of the firm's top clients has significant client visibility , the

business is expected to reconcile a client's trade file soon after receiving it, but such

reconciliations often took days of laborious and manual work, forcing the business to

search for trades in various systems and then make educated guesses about how to

match trades submitted by the client with trades as they existed in the firm's trading

systems. I took the initiative to analyze the process holistically, by speaking to the

business users and observing their work processes and pain points, and then

leveraging the best applicable technology to fundamentally redesign the reconciliation

tool. The new reconciliation has drastically reduced the time each reconciliation takes

(literally from DAYS to MINUTES) and improved match accuracy to 99.99%, creating a

positive reputational impression with clients, and freeing up the business to focus on

growing the firm's soft dollar business.

Many- to- Many matching is a long waiting feature for commission management and it

needs a good algorithm to handle many different match schemas. As one of major

objectives, we completely redesigned reconciliation tool and developed and

implemented many-to-many matching, we further increased the reconciliation matching

rate for client with aggregation role like Alliance and further shorten the reconciliation

time by avoiding manual matching. Our service team uses it to reconcile client trades

constantly and improve client service quality and response time significantly. CAS

Business owner comments this tool as following:

"I just did Fidelity in less than 30 minutes, which normally takes up to 5 days. Outstanding work guys!

This is an incredible leap forward and positions us well in a resource constrained environment while

greatly improving our rec turnaround times for clients."

Markit Commission Manager Integration:

Markit Commission Manager is third party system to report soft trade and payment to

buy side client. The system is sponsored by major brokers including Barclays, JP

Morgan, and Goldman etc and also gives buy side clients a chance to compare the

services among different brokers. I am the tech representative from Barclays to review

and define the initial functionalities, and also the designer and builder of Barclays’

integration application with Markit Commission Manager. Markit provides both SOAP

and file based API to upload trades and payments, considering SOAP APIs having real

time and better interactive capability, we decide to use their SOAP API and became the

only broker leveraging this technology and gain many advantages by providing real time

trade reports and allow buy side to submit invoice from either Markit or Barclays’

commission management system.

System Migration: Infrastructure migration is firm wide tasks and became challenge since missing support

from legacy system and tight timeline. I have taken full responsible for system migration

including OS, database and web application server etc. One of big challenge for

migrations is how to test and make sure all the existing features as it was. We had built

some test tools to help both tech team and business team to guaranty all migration

effort success.

Ownership and cooperation: Take ownership and coordinate with other teams to complete complex project.

Here is manager’s comment:

“Wei has taken owndership of a number of critical processes and projects. For example, he has taken

ownership of our interactions with the vendor Markit (which is a vendor application used by both buy-

side clients and sell-side brokers across the street, which exposes the firm to comparisons by clients to

other sell-side brokers). Wei immediately addresses any Markit-related issues, and has developed tools

for RTB to easily onboard and support clients. These efforts allow Barclays to distinguish itself from its

peers. he has also been instrumental and a dependable and trusted source in the team's effort to help

the business reconcile its soft dollar data with the FISS system. His willingness to take ownership of

processes and projects is a sign of leadership, helps the team and business, and shows maturity in his

career development.”

“Wei is careful in his development, making sure that his code is as bug-free as possible, proactively

identifying potential issues and finding creative solutions to solve them. he carefully designs, builds and

tests to deliver a highly-reliable work product. Over time, I and the rest of the team, as well as our

4

buinsess users, have come to trust and rely on his work, and his conscientous efforts greatly contribute

to the stability of our applications.”

“Overall, Wei demonstrates the willingness and ability to fundamentally improve workflows and

functionality by leveraging his technical and business knowledge, and his ability to analyze and

understand business workflows and pain points. He takes ownership of projects and tasks, is self-

directed, and is careful to produce stable code that balances short-term needs with long-term goals.”
