Mortgage Analytics (Structured Products Group). MBS (Mortgage-Backed Securities) - cashflows, prepayment, pricing.Technologies: Unix/Linux, C/C++, Perl, Python, Sybase, Excel VBA.Played a key role in migrating legacy C++ calculators (Fixed Income MBS) across data centers. Personally fixed and migrated ~100 applications, including old C/C++ applications, batch jobs, scripts used by modeling groups, and web applications. Wrote multiple Perl modules and applications (data feeds, utilities, monitoring, docs-builder system) to both help the migration and to streamline the nightly batch processesInstrumented analytical calculators to measure cpu time, instrument ids and categories, etc. These metrics would later be used to generate reports to identify how the resources were allocatedDeveloped Excel VBA applications used for regression analysis, and as a frontend for analytical calculators implemented in C++

As part of a consulting team from Hewlett Packard participated in a short-term project reviewing architecture of ETL processes (Extract-Transform-Load) and data flows in several datastores in Private Banking at JPMorgan-Chase. The goal of the review was to find how the system should be changed to be capable to process more data (x5 and more) in the same time frame. I was invited mostly because of my Sybase expertise.
