Enterprise Software Architect, ARS Consulting

Responsibilities:

• Enterprise Architectural Design of Open Source components and tools: Designed Software Architecture for scalable and multi-tenant Software-as-a-Service (SaaS) enterprise web using enterprise services of navigation, applications, platform and infrastructure services, and deploying composite-applications as enterprise services to utilize cloud-based computing with Service Components Architecture (SCA)/SOA/ Integration architecture. Designed modularize applications by grouping components into composites and connectivity of multiple transports for distributed communications, advanced asynchronous messaging, and eventing patterns for pub/sub eventing. Defined enterprise security strategies for single sign-on, data-, object- and application-level authentication, authorization and auditing, and data encryption using SSL.Design of Software Development Life-Cycle (SDLC) Model: Designed a Software Development Life-cycle model (combination of known eXtreme Programming-'XP' and 'V' Models) consists of Analysis, Design, Implementation, and Testing phases, and Risk Analysis classified into Performance, Cost, Schedule, and Support (Architectural spike solutions and managing using use tools to track implementation and small ptototypes to test approaches). Designed landscape-diagrams for development, testing/, and production environments using open source components & tools, deployment and configuration parameters. Researched on Internet for best practices, features of available open source frameworks/components/tools, coding techniques in the IT industry
• Composite-Applications Design, Development and Deployment strategies: Designed complete distributed, extendable and multi-clustered composite-applications using navigation services like login, search, personalize, collaboration, etc.; platform services like security, transaction, reporting, connectivity, persistency, mail, etc., To deliver robust and reliable composites using recovery manager & timer components. Designed a solution for application modularity where components are composed into loosely coupled subsystems e.g. ERP, BI, KM, BPM, CMS, IDM and ADM resources using web services & RESTful services to enable data flow in and out of the systems. For design-time, an Integrated Development Environment (IDE) with plug-ins for modeling, reporting, mobility etc. with a centralized version control system, and for run-time an open source component-based programming model to assemble and manage composite-applications are recommended.
• Design of Documents for Blueprint-Implementation-Testing phases: Designed the document formats for Complete Software Development Life-cycle phases for the members of development teams and the Governance documents using Microsoft Word & Excel. Prepared the design documents and presentations using Microsoft Visio & PowerPoint respectively. The Complete SDLC documents-list includes User Stories, User-Roles Matrix and Role-Processes Matrix, Functional decomposition, Process-, Activity-, & Component- diagrams, Functional & Technical Specs of the composites, Development Tracking Worksheet, Scenario test-scripts and User Acceptance tests, etc.
• Prototyping and Proof-of-Concept (POC) Development: A comparative study was done between the features of JBoss Portal and Liferay Portal. A prototype is developed on Liferay Portal CE 6.1.1 on Tomcat7, configured with ApacheDS 2.0 LDAP for user authentication and integrated with backend applications using Single Sign-on. Portlets were developed using composite applications on fabric3 1.9.6 SCA runtime. User Interfaces for Desktop/Mobile apps are developed using JQuery & AlloyUI - a YUI 3-based component library from Liferay; JVM-based applications are developed using Spring frameworks - MVC, IOC, Security & Batch; Integration to enterprise services using SOAP & REST APIs, Amazon Web Services (AWS) Management Console to manage EC2, S3 and VPC for eCommerce and Cloud computing development & Administration activities using admin/monitoring tools; and Enterprise Security e.g. Authentication/Authorization for distributed open source components using Penrose Virtual Directory & Studio.
• Design of Virtual Machines for leading Open Source components: Prepared comparative study of Virtual Machine containers e.g. VMware, VirtualBox, KVM, etc. Designed the virtualization for CentOS 6.2 Ubuntu 64-bit (Guest OS) on Microsoft Windows platform (Host OS) using Oracle VirtualBox 4.3.4 and its Extension packs. Participated in the processes of installation and configuration of VirtualBox on Windows platform and setting up complete infrastructure with SMEs. Created new Virtual Machines with 'Existing Virtual Hard Drive' and 'Importing Appliance' approaches of Oracle VM VirtualBox Manager for VM images. Configured 'Network Interfaces' for WebUIs of Virtual Machines, Custom Interfaces were developed for distributed applications using web services - remote (SOAP) clients of Main API of VirtualBoxSDK.
• Design of BigData and Caching Technologies for performance: The Hadoop Ecosystem, a Java-based programming framework for the processing and managing of large datasets i.e. NoSQL in a distributed computing and cluster environment - Hadoop Distributed File System (HDFS) for storage, MapReduce/YARN(retain backward compatibility with MapReduceAPI) for processing, and various data & operational services (essential/supportive); and for services/applications suite like Elastic and Hue as packages from software vendors Amazon AWS, Cloudera CDH and Hortonworks HDP; and for caching techniques in-memory distributed key-value pair caching using Memcached, in-process/distributed using EhCache (core) and to query, search & analyze cache entries using EhCache Search (an addition to the core EhCache API) from Terracotta.
• Built a prototype of Multi-Use Data Platform on YARN: Upgraded the landscape for Hadoop 2.0 (YARN for Cluster Resource Management and Tez as Execution Engine) and uploaded data files using File Browser. Created tables from the files into default database, and then imported the data into the tables of HCatalog/WebHCat. Created the Pig scripts to perform Pig operations on the data. Queried the data in HDFS2 using HiveQLs in the Beeswax tool - the Hive script has used the website logs data by joining with users & products info to generate an analytics view. For security and administration the following tools were used - Knoz Gateway, Cloudera Manager/Ambari - Ganglia and Nagios.
• Developed a plan to integrate Hadoop into SAP Software landscape: Using SAP's Architecture for SAP Real-time Data Platform, designed an architectural model for a client who has SAP Software landscape for its business operations and the valuable marketing info as big data captured from company's website. In the design - Hadoop, SAP HANA and, SAP Sybase IQ are integrated as main components for the use cases like Social CRM, Predictive Analytics, etc. and other business problems. The solution has leveraged the Hadoop features to handle big data efficiently and as flexible data store, unixODBC Driver Manager to open the Hive server data source in IQ, and BI tools & Analytics solutions of SAP HANA platform for fast access, real-time analysis and in-memory computing.
• Design the robust & fail-safe solutions leveraging existing IT resources: Provided the solutions for various problems using SAP & Non-SAP resources in security, enterprise content, transactional and analytical areas, designed scalable/integrated architecture for development & testing, administration & operational activities. Developed the prototypes using SAP Cloud Application Studio tool integrating web services like REST & SOAP and ByDesign Solutions; Customized UIs with Object-based & User Experience technologies; Analytics creating custom data sources, joins, keyfigures & reports; and Coding with object-oriented language BODL and scripting languages like ABSL & Ruby with using the NW RFC SDK library and Ruby-FFI to access the library.
