Drove adoption of testing as an integral part of the development process. Implemented automated unit testing using Karma+Jasmine and TestNG and automated functional testing using Katalon. For each pull request we are building and deploying an application and running battery of UI and REST API tests.

The real time trade processing included number of interfaces with external parties:
clearing the trade at a clearing house (LCH or CME) using messages containing FpML (Financial products Markup Language) transmitted over Websphere MQ
reporting trade to DTCC (a Securities Data Repository) by transmitting FpML using Websphere MQ (with security exit implemented)
notifying the parties of the trade for straight-through processing over Markitwire native library using SWBML or SCML for the dealer and cleared flows respectively
notifying the parties of the trade over FIX (either directly through ‘dropcopy’ or through Block Rock’s Aladdin offering)
generating and sending trade confirmation emails (PDFs)<br><img src="assets/images/logo-rabbitmq.svg" width="150">

Developed internal regression testing methodology which compared over 40,000 artifacts generated by the Post Trade system (FpMLs, SWBML, Emails, etc.) with the same artifacts generated using previous version of the application. The resulting report was reviewed by Product and Onboarding teams to verify all changes going into a release were expected and correct.

Built a global distributed cache for FX applications (based on GemFire) containing over 100 caches with more than 4 million pieces of data spanning 6 data centers globally. The system is accessible over generic caching API (CCache; based on JSR107). Pluggable transports allow for using native GemFire connections as well as JMS (over Tibco EMS) or plain sockets. Propagation time from North America to Asia is <1s. HTTP REST and JMX interfaces allow for browsing, administering and monitoring the cache. This system is used by nearly all FX applications as it provides currency, calendar, warehouse routing, customer lookup and pricing branch functionality. The CCache library is loaded in hundreds of processes and provides in-process calculations based on pushed base data (currency calendars, existing warehouses, etc.). Depending on size, some data is lazy loaded while other fully preloaded.

Replaced custom Tibco EMS setup that was causing numerous outages with a new federated approach using standard packages sourced from Citi’s Engineering Team and using broker management application developed by Equities team (included change management process and rollback). This infrastructure was then handed off to Production Support team, which further reduced cost. The development teams were educated on the new process and given ownership and responsibility for their brokers. Number of instances grew from 4 to 26 (18 in North America, 6 in Europe and 2 in Asia). This process also upgraded all instances from version 5.3 to 6.1 as well as included remediation of various issues found by external audit. <br>

Development lead for Targeted Orders (Instinet’s first application in the ‘block trading’ initiative). Targeted Orders are large orders that are advertised to parties selected based on filters created by the traders. Filters include criteria such as type of client (institutional, fund, etc.), holdings and other. This facility included a web application for creation of filters and viewing execution reports, middle-ware connecting to trading system and evaluator servers for target-client selection. Visited clients to seek feedback and recruit for beta testing. Trained support personnel.

Designed and developed ‘BookMark’ which was Instinet's web-based full book delivery product and answer to a Island’s (fast growing competitor) similar offering. The data was tunneled over HTTP to Java applet. Self-healing middleware managed interaction between the client and a number of Book Servers. Libraries from this product were used in Instinet's Newport product (full featured Execution Management System).

Lead developer for Server Management facility to manage and monitor server applications. The client console communicated with middleware (Hub) which acted as a multiplexer to hundreds of server processes that implemented a custom protocol. The console included template view of server's events, list of available commands and general health of applications. Hubs combined into domains to support multiple environments (development, user acceptance testing and production).
