# Architecture redesign - Designed scalable, distributed applications to serve millions of requests via Akka streaming pipelines, ES, Kafka, and Cassandra in a distributed multi-host clustered container with Akka modules that resulted in a highly distributed, scalable solution along with optimal resource utilization.
# Scalability - Migrated core component from JVM based in memory cache to independent service that serves queries via DB along with distributed cache as part of loose coupling.
This has significantly reduced the memory and cpu bottleneck with a tradeoff of actor based to GRPC API calls, however with clustered postgress DB instances permformance and scalabiltiy target SLA achieved.
# Performance impact - Built ETL pipelines with QPS of 7k-8k within kafka cluster using akka router module on multi host Kubernetes environment
# Migration to cloud - Migrated MCP solution with 300+ componnents , 50+ microservices from docker based multihost (5+1, 3+5) clustered container to Cloud Kubernetes environment to achieve scale and performance targets of resources.

# My resposibilities include creating scalable micro services, architect design, HLD and LLD implementation till end to end delivery and further improvements and maintainance along A/B testing etc. I scaled service api performances upto 4 times that resulted the system to perform fault tolerant and with low latency and high throughput availability using algorithmic optimizations, query performance improvements, JVM tuning, multithreading asynchronous execution.
# Apart from this I have worked on technologies like AWS SNS, AWS Lambdas for real time syncing of applications, Firebase Realtime DB and Firebase functions for Chat application etc.
# I have designed the microservice based achitecture on server side with play framework to deliver resilient, scalable and extensible features in backend to empower the client side.

Nov 2017 – Jul 2019 · 1 yr 8 mos · New Delhi Area, India

As an Associate Software Developer I got expertiise in building Fully functional web applications Rest API and SOAP web applications.
# ATS Terminal Import – A SCALA/SBT project which imports big data from AWS s3 third party venders and transform the data and push them on client servers
Achivements :-
I managed to process millions request through AKKA based concurrency via multithreading with scala futures api and gigabytes of data every hour .
# Lever Vender Integration – With the use of Lever(US TOP HIRING PORTAL) Connectors integration , different automations are achieved by mixing triggers and actions. Lever is a recruiting tool designed to help companies take candidates through the hiring pipeline.
# Integrated number of market players(US TOP NOTCH COMPANIES) through LEVER PORTAL and deasigned a fully automated fault tolerant scalable system to process the candidates.
I got the oppurtunity to work as a front-end developer here as well and designed dashboard/Portal to manage the candidate data.
# Worked on other projects with MEVN techstack and designed jobs to process data and created dashboards.
