Accomplishments

My Primary Job role is Senior Tech lead and Consultant . I am responsible for modernization of different debit card operation in the Retail Banking Operation . Currently the debit card operations are using Master Card payment processing system. I am currently the lead developer and also leading a multi geography team of 7 for this program .

My primary Job role is to act as senior consultant with the client and understand the requirement and help in rollout of the same in planned manner . As a developer I am responsible for developing a mediator application which can interact with different payment processor along side Master Card. We are currently rolling out the same operations for FIS Global as exists for Master Card. The application is primarily developed in Spring Boot and we use Wiremock to simulate transactions.

By implementing wiremock we were able to mock different Debit card operations with actual request response for both the processor without having to actually go through the actual B2B WS call.

We used postman for creating newman integration tests based on wiremock response and compared them for both MPTS and FIS to see if the results are as similar as downstream api(s) would expect a seamless experience.

We also developed a piloting logic to switch between two payment processor and aid in slow roll out of BIN(range of card) . The piloting logic is based on a db based config table form which we read the range and based on the card no used for doing inquiry or update operation we route to the appropriate processor. We also have implemented a concept of dual processor if in any case we need response from either one of processor during migration we would get an actual response back .

We have also created a connector project whose primary role is to take requests from different down stream application to either route to MPTS or to Mediator which will in turn decide which processor to route based on Gloo edge envoy configuration for traffic routing.

We have also implemented caching of oauth token to be used as part of authentication for FIS. Have configured oasis WSSE for MPTS also .

We have configured gitlab ci/cd to perform build, quality check, run integration test . and deploy to ocp clusters ..

I have also contributed in migration of websphere based batch to spring boot based batch . We have implemented nfs storage and read files from nfs to be updated to db also worked on control-m

Accomplishments

My primary job role is to design and lay down framework for further development . Aid senior architect in solutioning .

The project mainly deals with reconciliation or settlement of swift messages .

We consume the message from an external gateway though an adapter using spring cloud integration in unstructured form . The data is splitted and saved as key value pair in Marklogic form the same adapter.

The entire adapter is designed using domain driven design pattern strictly abiding to CQRS pattern.

The adapter triggers a matching process in the matching engine .

I have extensively helped my senior architect to design and conceptualize a matching solution based on Marklogic Data Hub framework based on spring boot .

The spring boot batch utilizes Datahub Framework to create flows for Ingestion, Mapping and matching . All the processes are segregated into sperate spring boot batch task grouped into a single tasklet.

The outcome is sent back to the initiating adapter using spring cloud kafka streams.

Base on configurable matching rules we were able to reduce the reliance on manual matching process to a considerable extent. We have also built custom matching rules using fata hub framework in marklogic.

We were responsible for creating Bamboo pipeline and for implementing ci cd . We had scripted a groovy script which was responsible for creatign different stages in the pipeline. We had following stages in our jenkins pipeline

a) Fetch From git

b) Fortify Scan

c) Clean build copy to artifactory.

d) Deploy

e) SOnar Scan

f) Run Acceptance test.

We also had a acceptance test framework where by we create jbhevae story in jira and the same was executed by the acceptance test application using jira Theodosius plugin. We had developed a full suite of application which can automate the acceptance criteria from ba`s and thus eliminating to a great extent the process of manual testing

I have also lead a team of 8 members to develop the entire application and have contributed toward critical problem solving initiative and ensuring smooth delivery of the team besides my delivery .

We created docker images of the microservice and pushed them into private docker registry from where it was pushed into a Kubernetes pod.

Accomplishments

As a full stack developer I am responsible to create framework for data ingestion and api based on microservices to be deployed on cloud.

Client has legacy system in mainframe and for various purposes data from the same was to be exposed as a service for different consumers.

I am part of Data as a service team the primary responsibility of which was to source data from different sources and expose them as a service.

We designed a data ingestion framework based on spring boot and was deployed on pcf . The primary functionality of the same was to retrieve files from mainframe or hadoop and transform that data and store in mongo db.

For each data ingestion project we had metadata associated which would tell the framework the different control parameters to parse the file . This was stored in Maria db and each time a file is processed the same was read and the the info was used to transform data and store in mongo db.

We were also responsible for creating microservices for api and used service discovery from zull to present a unified api experience.

We had the requirement to implement api across multiple data sources and and some times orchestrate them as well . For this purpose we had used graphql query language to create cross data source joins which can be used to create response which contain data from different data source like hadoop mongo db mariadb etc. For this we created type definition and ype arguments. The e of this was that it automatically created input parameters for api based on metadata information . Also we can specify what or how many fields we may want in response.

For the purpose of creating this microservice(both api and data ingestion) we had a config server deployed on PCF from which the details of service was fetched during deployment time and bound with the application .

We followed the methodology for tdd during coding .

We were responsible for creating jenkins pipeline and for implementing ci cd . We had scripted a groovy script which was responsible for creatign different stages in the pipeline. We had following stages in our jenkins pipeline

a) Fetch From git

b) Fortify Scan

c) Clean build copy to artifactory.

The same data was exposed to using rest service which was consumed in d3 client and sorted using crossfilter to display alerts, tickets for all kind of sensors related chart.

I was responsible for creating an outage app using db2 and hibernate as the orm layer for a electricity supply company. The app basically reported the outage information as a push notification on mobile device based on data realtime data feed from the company. We used IBM Bleumix cloud integration to fetch data from mqtt and persisted the same on the IBM Bluemix db2 service. We used a geocoding tool available in bluemix to plot the same on a gis map.

I was responsible for creating the smart offer based solution for a banking client. Depending on the location of a mobile device the gps coordinate of the same is provided to Bleumix MAS service which consumed the same and used business rules to calculate what offers are currently available in which stores nearby to his coordinate and the same was made available in real time to the user. We used db2 service, cloud integration, nodejs and mas for mobile device to develop this application .

I was also responsible for creating a log analyzer application and realtime monitoring of alert management integrated with a mobile solution based on log analysis. The application in context read log files from object storage in Bluemix a log analyzer was used to process the log files line by line and store the same in cloudant. Db

Used nodejs, cloudant,object storage, Mobile application and security as well as db2 services available on bluemix to store the metadata as well as the log data.
