PROFESSIONAL EXPERIENCE:

Confidential

Application Architect

Responsibilities:

• Understand the existing Argo Platform and while enhancing the code to support current business, while we were re-designing the new platform.
• I was instrumental in coming up with architecture for the new System and present it to VP and our team.
• Since team had little to no expertise with Kafka (Queues), Graylog (log monitoring and alerting via API), MongoDB (for storing configurations for each application, ETL configurations, Scan Metadata), I need to come up with proof of concepts to prove decoupling, alerting error logs to API and take actions, Web Sockets for low latency communication.
• Evaluated storing of ETL data with MongoDB and Elastic Search.
• Used Elastic Search for storing the ETL data which helped YP-Search team etc, to query ES directly.
• I was involved with prototyping micro services applications (running inside tomcat server) on Mesos using Docker images, this was to prove scalability.
• I came up with framework for micro service applications using Spring MVC, MongoDB DAO, Elastic Search Client. Created Kafka Client as a framework (configurable via MongoDB), so that every other application can connect to Kafka queues for inter communication with less dependency and less code.
• Created Redis cache Client (configurable via MongoDB) and applications were using them as maven dependency and hence less boiler plate code.
• Created a Map-Reduce jobs framework, to read from various legacy as well as new data stores such as HDFS, Elastic Search, MongoDB and write to Hive, Elastic Search, MongoDB with multiple combinations.
• Used RabbitMQ to support Priority of message processing for batch scans.
• Added Couchbase as a persistent caching solution for old Argo platform while we were implementing the new platform (which used Redis as caching solution).
• Created ETL framework to support both HTML and JSON raw data parsing using JSoup and Jolt APIs driven by configurable CSS and JSON paths. Also, created a golden set to monitor the Html changes on the source site and accordingly adjust the CSS paths to support ETL in near real time.

Environment: Linux Cent OS, Mac for development, Tomcat 8.5, Maven build.

Confidential, Minneapolis

Architect

Responsibilities:

• Reviewed Architecture, Design documents.
• Analysis of custom code that comprised several reports and CRUD operation screens.
• Profiled the reports and application using JProfiler to identify the bottle necks and base lined the metrics.
• Identified the long running SQL’s, tuned them and verified using Visual Explain tool.
• Designed new batch process to offline the SQL’s, which were querying huge volume (5 million records) tables in online. Thus improved the response time for each SQL’s from 12 seconds to 150 milliseconds.
• Database re-design (ERD).
• Refactored the application code to use Struts frame work.
• Created read only connection pools exclusively for reports.
• Refactored parts of the java code.
• Modified the reports JSP pages to use JSON (Ajax) based implementation, and thus reduced the page size from 4 MB to 1 MB and decreased the response time from 50 sec to 20 sec. These reports were heavily used by the store users. On an average 3 users from each store uses these reports at least 10 - 15 times while editing schedules. This solved most of the congestion problems that were constantly causing servers to go down.
• Modified the existing report JSP’s to print the same page rather than opening a new page for printing purpose, which was holding ~8 MB in session.
• Increased the Session bean queues.
• Tuned WebSphere parameters such as JSP pre compilation, tuned web server and app server threads, increased the connection pool size.
• Unit testing.
• Integration testing.
• Production support.

Consultant

Responsibilities:

• DB2 has a purge tool, but it requires some criteria to the tables purging.
• Work brain application has enforced all the tables to have client id column.
• Thus the purging process is divided into two steps; mark all the records with client id as ‘0’ and sweep using DB2 tool.
• Initially team designed marking process with JCL on Mainframe system where the DB2 is running, later they found it was taking roughly 15 hours to update 25 million records.
• I involved in doing the proof of concept (POC) using Java, and designed a working model that took ~1.5 hours to update the 25 million records. Thus I came with a framework for marking process which had around 27 scenarios. My activities involved in marking framework:
• Design of Marking frame work.
• Designed XML schema for SQL parameters like queries, connection pool size, commit frequency, thread count.
• Used Javolution concurrency framework for multi-threading.
• Used JAXB for parsing the SQL configuration.
• Wrote SQL queries for Select and Update and tuned them using Visual Explain.
• Integration testing.
• Production support.
