\section{Accomplished Projects}

\begin{itemize-noindent}
\item{I have managed to automate all Roaming, Interconnect and Loyalty Campaign related processes and reporting with in a period of one month after joining Tenotree Corporation}
\item{I was part of the team involved in the implementation of UTL Prepaid Commission Model, Churn, Prediction Model and   Micro Segmentation   of   UTL’s   Subscriber base}
\item{Implemented a real time raw CDR collector for prepaid UTL customers which resulted into timely, accurate reporting and support for running various promotions (awakening and activation bonus promotions)}
\item{Implemented a software solution using Perl to generate notification Tap files for UTL inbound roamers. This saved the company 40000 Euro that was required for regeneration of over 100,000 notification by the Clearing house} 
\item{Implemented a software solution using Perl to correct billing information for RAPs (Rejected Tap files for UTL inbound roamers)} 
\item{Implemented a raw CDR decoder using Perl for MSC (mobile switch)} 
\item{Managed to resolve major Tap file exchange challenges between UTL and Data Clearing House (DCH). This helped the company to recover from huge revenue losses that were caused by files aging before reaching the DCH. This was achieved by implementing a number of controls and quality checks like successful ftp delivery reports} 
\item{I was involved in the design, analysis and implementation (using python) of UTL bonus airtime model which came in handy during a number of acquisition campaigns}
\item{Implemented the good number algorithm in python for   classification of UTL free number pool}
\item{I implemented a Near Real Time Roaming Data Exchange (NRTRDE) solution for roaming fraud detection using python which save UTL over 100,000USD that was to be charged by the vendor to implement the same solution. Solution is still being used by UTL}
