Member of technical team on $5M+ initiative to design current and future enterprise architecture, create roadmaps, develop and deploy software solutions, and implement improvements. Carry out requirements gathering, solution development, road mapping, timeline design, assessments, modernization, systems migration, technology selection, architecture configuration, and software/system development.
·Aligned IT vision with business by defining SOA target architecture and creating roadmaps will be in next one, two and three years.
·Improved development processes by implementing Infrastructure Life Cycle Plan and Legacy Migration plan. Created AS-IS and target enterprise architectures
·Greatly improvedSOA migration process by designing SOA Reference Model
·Created Architectural artifacts such as Business Case, SOA Governance, SOA Road Map, SOA Test Plan, Service Model & Contract Templates, SOA Infrastructure Plan
·Leveraged SOA to abstract legacy assets as Services and composed legacy based services with other services
·Able to meet, implement and enforce new regulatory requirements enterprise-wide and gain instant visibility
·Reduced redundant information, processes and introduced consistent method for describing services across organization
·Successfully implemented SOA by bringing a cultural change in thinking process among developers and by creating a shared vision between business, architects and developers.
·Architected eight different Services. Value of the design was realized when the services were composed and reused as parts of various business processes that demanded varying degrees of granularity and greater performance metrics.
·Researched and implemented business processes orchestration and “Entity Aggregation” pattern to increase scalability, composability, loose coupling and abstraction.
·Created detailed Software Architecture Documents and provided requirements traceability matrix and conducted design handoff and code reviews with Developers.
·Architected $2M legacy system to be web based system
·Enhanced performance 47% by re-factoring legacy systems and deleting 100,000 lines of redundant code.
·Increased system availability 23% and cut development costs $1.5M per year by introducing centralized web services for approximately 45% of all NYPD applications.
·Designed retiring legacy systems to web based application using MVC framework (Spring-Hibernate)
·Successfully lead a cross functional team in defining and creating a Canonical Data/Domain Model. CDM helped to achieve better interoperability among disparate systems and reduced the need to create and maintain different versions of the same service.
·Defined integration policies for the 3rd party vendors, prepared statement of work documents
·Increased efficiency by introducing agile development methodology to program.
·Took on role of Project Manager and supervised 15-person development team. Led development of web-based workflow engine and integrated engine with legacy systems.
·Successfully upgraded DB2 databases and modernized legacy applications.
·Reduced costs by migrating systems to web-based applications and retiring legacy systems.
·Reduced maintenance and development costs $1.8M per year by introducing reuse into development process. Also increased performance metrics.
·Established Schema Committee to develop and document XML principles, standards, and best practices.
·Managed 11-person cross-functional team in identifying applications for modernization.
·Mentored 5 member development team to successfully deliver web based system on time
·Member of various studies including
oXML Binding Tools Evaluation – JAXB 2.0,XML Beans & Castor
oCaching Tools Evaluation – OS Cache
oESB Transformations and Assemblies
oService Orchestration on ESB using BPEL and Content Based Routing
