Team Lead - Senior .NET Developer/ Application Architect

Responsibilities:

• Working as Application Architect/Developer and leading the development effort onsite and offshore for myship web application that handles all of Macys and Bloomingdales shipping from fulfillment stores, Warehouses and Mega centers
• Responsibilities include management of outbound shipping, roadmap, and release schedules; identification, prioritization, and documentation of product requirements; collaborating with onsite and offshore development to define scope and implementation approach, interact with business and technology partners for carrier compliance and needs. Ensure engineered environments meet specifications in terms of business requirements, application design and infrastructure requirements and accountable for the performance and efficiency of platforms.
• Establish architectural governance reviewing projects to ensure alignment to architectural and technical strategy.
• Joined this project when entire team left with missing source code in repository and holiday season was in the offing. Gained management confidence and rebuild missing source code and found all missing pieces such as servers, SQL scripts and other configurations. Supported the application during peak season where the application received 27 million hits in 4 days. Did performance monitoring using Perfmon tools to check active connection thread counts. The elastic search dashboard was used to check spiking servers.
• Developed core shipping logic component and features using Progistics COM+ DLL. Redesigned same using AMP REST services to be rolled next year.
• Used number of advanced MVC4 features along with AngularJS and bootstrap. The application is broken into three pieces to handle the load for Stores, Warehouses and Close out processes on separate servers. Implemented Scan Print Apply (SPA) for automated shipping whichreduced the shipping labor by over 95%.Developed and consumed several web services.
• Developed composite and Hybrid feature rich MVC4 SPA dashboard using Angular that gives access to several features required by field people as well as corporate higher management for reporting purposes. Created wizard based utilities to move user from one store to another store and assign them resources at that location such as printers that prints the shipping labels and documents along with gift cards if any. Management users can log onto dashboard from a smart device or web dashboard to view number of shipments and other useful reports. Fuel and tariff surcharge, EVS file transmission reporting is also implemented as wizards. These utilities are made part of dashboard where this task can be performed by store manager thus eliminating dependency or expertise of development team. Team can start and stop windows services with a switch and provide database view to perform certain tasks.
• Developed self support portal with Email service broker design where users can send an email to pre-defined email addresses with specific subject line code and additional details and the service would react based on code perform task and send out email notification with results. There were around 20 such codes where business could just send an email to reset locked user, or change user store, or add new user to store, change his AD entries etc.
• Independently developed Invoice solution to replace legacy source tech vendor application that was out at all facilities for over 10 years. This was developed in 40 days for 4 warehouses that prints Macys, Bloomingdales and International Invoices as high as 10,000 an hour. Invoices were generated from Mainframe flat files that are parsed and converted to .NET objects and bound to PDF form fields using iTextsharp with highly configurable fields to match Invoice requirements based on different criteria. Windows services are written to watch folders that receive files from Fedfil and WMS after which Invoice generation triggers and are printed on preconfigured printers on servers mapped to mainframe U-Numbers with load balance logic embedded. Windows services silently print invoices using Ghost Script. Invoice generation and service alerts are sent out using an Email component. Multiple modes of printing are implemented that are configured from config file. Used threading and blocking collection for Producer Consumer pattern. Millions of invoices and picking document with bar codes are generated to date with zero defects to date. This solution saved Macys over 8 million each year per facility.
• Developed AD component for application that authenticates the user and handles multiple application related features such as enabling disabling scan-scan option and assign default store and printers to associates. Developed user session management and single session sign on preventing associates to use multiple terminals for shipping process.
• Help set up elastic search dashboard with Kibana, log-stash that was used for peak monitoring of Myship website that gave insight to servers, which page or which method is slow or time consuming and bar code details in addition that helped find issues quickly. Configured file-beat on servers to comply to new version of logstash server
• Developed a design for Myship Mobile that would be used for shipping for high value items initially and then rolled out to store fulfillment.
• Modified application for use on Magellan registers for jewelry fulfillment to print shipping labels using wireless Zebra printers. Worked with network team for find issues on Zebra printer connectivity on 5GHz to comply Confidential ’s wifi policies and requested Zebra new patch for compliance purposes.
• Developed configuration dashboard using groovy - grails - JAVA for WMS support. The dashboard can add bypass lanes along with other helpful features that eliminates need to create tickets.
• Migrated Connectship version 6.4 to 6.5 eliminating XML processor and utilize Amp Web Services. Developed core shipping logic in C# inside web application using Progistics API and custom scripts for Connectship PMC tool. Responsible for installation and configuration of Connectship 6.5, monthly fuel surcharge updates, custom rates upload.
• Configured Connectship servers for stores and warehouses and Handles configurations for 10 Connectship servers, 10 FSMS FedEx and 15 server farms with 2 database servers
• Developed carrier data feed component to consume data feeds/push from UPS (UPS Quantum), USPS and FEDEX for EDI messages and serialize this to oracle database for shipment visibility via TIBCO MSFT. Publish and Subscribe to TIBCO EMS queue for data.
• SSRS report development for Carrier Penetration Data to determine the shipments expected by carrier based on service levels.
• Responsible for handling FedEx FSMS high volume server and work on day to day basis with FedEx ACE technical team. Responsible for FSMS configuration settings and bridge Connectship and FSMS servers.
• Help redesign fundamental problem of rating and shipping call across Connectship cluster and load balanced FSMS servers.
