• Deployed and maintained Catapult POS software remotely.• Wrote a page load time measuring shell script, that became part of a production unit test used to determine if report runtime increased significantly on version release, far more efficiently than previously used manual methods.• Supported existing Catapult production releases through the application of internal knowledge base scripts, used to resolve version oversights and defects post release.• Investigated and addressed customer related production issues of varying complexity, using front-end Catapult or back-end SA database or both, in a single assignment whenever possible.

● Ensured Wombat feed handler uptime > 98%.● Load balanced feeds across three data centers, and feed elements across servers as needed.● Intervened with realtime and delayed source feeds to fix data issues involving source exchange feeds.● Deployed multiple version controlled xml shared object configurations across different sets of feeds.● Created in-house Linux based feed handler missed message utility that scraped logs, dumped output to csv,and loaded output into Oracle database table.

● Worked on early phases of in-house back-end database of an internal customer reporting application.designed to improve customer experience by gathering and analyzing log statistics and metrics.● Gathered end-user feedback and needs for MagniFIX (3rd party log monitoring application) and convertedthem into build requirements.● Helped Hadoop engineers convert Oracle-SQL queries.

● Participated as technical point-of-contact for MagniFIX emergency change controls.● Helped other internal teams deploy multiple versions of MagniFIX across multiple environments and servers that often possessed large scope due to complex configuration changes.● Trained and mentored team members on new 3rd party apps and in-house tools/utilities.● Created SPLUNK dashboards that quickly summarized mission critical application processes to help monitor health and better triage production issues when they arose.

● Wrote bash/ksh shell scripts that helped analyze and resolve production issues more quickly.● Wrote ad-hoc SQL queries that helped identify short-term issues more quickly, and long-term trends more clearly, based on customer data, using Oracle-SQL.● Wrote VeriFIX scripts that automated complex tasks with far greater efficiency than prior manual effort.● Analyzed efficacy of CME user-defined-spread instruments, based on usage, resulting in conversion to more efficient exchange-defined-spreads, and cost savings across multiple business units.

● Conducted root cause analysis, with bias towards single-step resolution instead of escalation.● Wrote Solaris email distribution scripts that gathered and distributed Oracle csv and HTML output.● Wrote ad-hoc SQL queries to build various custom reports for internal support, marketing, and operations groups.

● Analyzed and investigated production issues from a second level help desk point of view.● Assisted first level support in creating trouble tickets, and taking customer calls as needed.● Converted a large database created using Microsoft Access to Oracle using sqlldr.

● Supported RTDMS (in-house in-memory database written in C) production instance using ksh and PERL.● Analyzed table insert failures to database resulting from mainframe-to-UNIX bad file transfers.● Resolved data transfer/formatting issues from database to downstream consumer applications.● Tested bug fix code changes and assisted senior developers with implementation.

● Managed users (add/modify/disable/delete).● Completed basic hardware (B/C class workstations, A/K/T-500/V class servers) support functions.● Resolved disk utilization issues (clean-up scripts, user quotas).● Distributed OS/application patches and minor upgrades (swdepot, swinstall).● Installed and maintained network printers (lpadmin, jetadmin).
