Retalix LTD. USA

• Led the technical efforts of implementing a new WMS product purchased by the Retalix from a 3rd party company. The WMS product is a robust warehouse management system designed to manage the daily operations of major retail warehouses; receiving and distributing thousands of products every day to the retailer’s chain of stores. The main goal of the system is to have the day to day operations as efficient as possible making sure no products get lost and all labor efficiency is maximized. The new WMS product is a web based application developed using ASP.NET 2.0, MSMQ over MS SQL 2005.
• As part of the implementation process I have reviewed the technical architecture of the WMS product analyzing gaps and potential points of failure that had to be fixed.
• Designed and implemented the architecture for the interfaces between the legacy products and the new WMS product. The interfaces were built as windows services using .NET 3.5 framework (C#) and applied business logic while consuming the data and processing it into the WMS database. All the data transferred between the systems was in XML format. The legacy systems are COBOL based running in a UNIX environment.
• Served as a technology subject expert for the group supporting the product manager and sales persons’ technical requests and queries and helped with the pre-sale processes.

Retalix LTD. USA

• Served as lead technical expert and integration specialist for the Loyalty product overseeing the first integration of the Loyalty Product with the US point of sale products. The Retalix Loyalty product is an enterprise level system designed to provide real-time loyalty and promotion services to a retailer’s chain of stores. It is a multi-discipline product composed from a Web based central application developed in C# .NET 2.0/3.5, .NET windows services and MSMQ over MS-SQL 2005; the Loyalty promotion engine, the client side was developed in C++ invoking the central’s web services and sending XML messages over HTTP and the MSMQ channels to get real time response to consumer loyalty card swipe and provide a current points balance and eligible promotions by the consumer demographics. The point of sale products are coded in C/C++ (Grocery POS) and Delphi (C-Store POS).
• Led a team of 3 development and support professionals. Assigning tasks, overseeing the execution and helping hands-on as needed.
• Based on customer business requirements, designed and developed new US specific modules for the Loyalty product using C# .NET 2.0 and later 3.5 frameworks, using XML format for all data communications over MS-SQL 2005.
• Designed and implemented the architecture for customer specific and generic interfaces to the Loyalty product. Interfaces were developed using C# .NET 2.0/3.5 creating windows services, console applications and web services. All the data transferred between the multiple systems was in XML format.
• Designed and developed a complete set of web services exposing almost all of the central application functionality. This was based on a partial customer requirement but was architecture and implemented as a generic SOA set of services. Later to be incorporated in the product as an out-of-the-box set of interfaces for internal and external application usage.
• Led technical gap analysis and workshops with customers, going over the product technical and business features and identifying customer needs and gaps to be addressed.
• Participated in the customer architecture meetings to help design the architecture of their interfaces layer and the integration of all their in-house and 3rd party systems to the Retalix products.
• Participated in pre-sale meetings on customer sites as the product technical expert.
• Coordinated all delivery schedules & contents with customers, the local development groups and the offshore development groups (Israel based).
• Configure and setup Loyalty systems for US Customers. Configurations are done through XML files and SQL scripts.
• Overseeing product installations and on-site support for the US customers. The Loyalty product is installed over a multi-servers farm, clustered and load balanced for redundancy and high availability of the application.
• Provided last level of support for troubleshooting and debugging issues on customer sites and providing configuration and code solutions in short turnaround timelines. Among the issues would be performance tuning, SQL data recovery and manipulation, .NET bug fixes, MSMQ issues and IIS / cluster configuration issues.
• Provided software architecture services for other Retalix product groups in the USA offices.
• Provided other Retalix product groups with MS-SQL expert services such as: data modeling, maintenance, performance tuning and troubleshooting (there is no DBA in the Plano office).
• Developed multiple “Proof of Concept” projects and support utilities for the group using .NET 3.5 framework (C#) in VS2008 utilizing the MS Entity framework and LINQ-to-Objects. Also used .NET framework 4.0 beta in VS2010. For example, a store send a few thousands transaction tickets a day. We needed a simulator program that simulates transactions sent from multiple stores/lanes. This winforms application was developed in .NET 2.0 and was used for unit testing, QA and performance testing of the application later to be adopted by other Retalix product groups.

Retalix LTD. Israel

• Managed a team of 5 development professionals: Three .NET developers, 1 QA Engineer and 1 DBA. My team was in charge of the H.Q. Grocery product, an enterprise price-book (catalog) management product with international customer base designed to manage the entire retail aspects of a grocery stores chain. The product was an ASP.NET application over MS-SQL 2005 using AJAX, XML, XSL and JS for the client side and .NET 1.1 & 2.0 with heavy stored procedure usage on the back end.
• Worked closely with the product manager and the project managers to ensure quality & timely delivery of the product versions. One of our major accomplishments was a successful, on-time, delivery of Retalix’ first customer in Japan delivering multi-tiered, multiple products environment.
• Participated in the system analysis of new modules for the products.
• In early 2005 my team and I led the product evolution to the new technology environments from.NET 1.1 ASPX web application and windows services over MS-SQL2000 to .NET 2.0 over MS-SQL2005. This was a major change in development environments and technology concepts. Extensive T-SQL work was done since the legacy product’s logic was in mainly the DB and we had to separate the logic layer from the data storage layer. We converted huge stored procedures (thousands lines of code) to .NET code using C#, creating a new business logic layer to build an appropriate MVC design pattern implementation.
• In 2006 the H.Q. Grocery & Loyalty products merged into one product and my team joined the Loyalty group. The code merge efforts was assigned to my team and included major SQL stored procedures merge and .NET business layers merge while removing duplicated functionality and adopting the best practices from both systems.
• Participated in the performance and load enhancement efforts for the Loyalty product, this was a group effort to make sure the Loyalty product can sustain a tier one retailer as Carrefour processing over 100 transactions per second on the central application. The enhancements were done to the database, the windows services and the .NET web services.
• In 2007 a new customer with over 2000 stores purchased the product and we had to re-architecture the download process, one of the most important and mission-critical processes in the system. I was assigned with the task and created a new scalable, efficient and robust architecture. The new architecture was based on a data flowing through a series of .NET windows services communicating XML messages through MSMQ which allowed the setup of multi server environment and data delivery guarantee.
