Tech Stack: Java, AWS(Lambda, DynamoDB, SQS, S3, ECS etc), Elastic Search, Terraform.● Common Libraries:○ Log Masking - Any service can use this framework to mask the sensitive data in their API logs.○ SQS Retrier: I created a framework where any service can retry their SQS messages with exponentialdelay. Used DynamoDB to save the retry information and a retry queue to hold the messages.● Click’N’Ship: I took this ownership, from grooming the requirements to designing the solution to writing the code by following SOLID principles, design patterns, and best practices.● Carrier Connectors: Integrated 10+ new carriers by creating their connectors and deploying them on AWS Lambda.● Test Data Loader: Created a quick AWS Lambda, exposing a few APIs which will load some data in thebackend so that new clients can have a look and feel of the SAAS product we have.

Tech Stack: Kotlin, SpringBoot, Kafka, MongoDB, Event-Driven.I worked there on the Axis Bank project. My contribution was in the following:1. Created APIs for vendors like GooglePay and CRED.2. Worked on making the lending journey digital. Worked on EKYC and Video-KYC.

Tech Stack: C# .Net CoreDesigned and Implemented services using AWS Lambda and SQS to reduce cost and maintainability.Developed REST APIs for the offering we need by taking care of proper documentation, best design patterns, configurations, logging, etc. Worked on the onboarding of a new Hotel Supplier. Worked on reducing the API serving time by making calls asynchronous, minimizing deserialization cost, etc.Used design patterns while implementing features in existing applications with a proper TDD approach.Enhanced existing system logging resulted in better Grafana dashboards, filtering logs in Kibana, and removal of false Twilio calls.Worked on managing the client-specific behavior using configurations to resolve things on the fly.Written a tool for production monitoring and showing the same on Grafana.Developed an API which is extracting the data from elastic search and loading it into a database further using another API to serve meaningful data to UI.
