WORK EXPERIENCE

Software Engineer in Paycom, USA Jan 2023 – Present

● Worked on an Expense Management application to deal with payroll of employees and conducted a value stream mapping exercise for the main production line, identifying bottlenecks and reducing overall lead time by 20%.

● Designed and developed a web application using HTML5, CSS3, Bootstrap, JavaScript (ES6) that met accessibility and web browser standards for websites

● Built and integrated three scalable RESTful APIs using Spring Boot and Spring Security with the front-end Angular application using TypeScript, ensuring seamless data flow, real-time updates, and enhanced security.

● Engineered high-performance RESTful API endpoints and web services using Node.js and Express.js, optimizing CRUD operations on a NoSQL (MongoDB) database. This boosted system reliability and reduced response times for data transactions.

● Integrated downstream APIs in our application after validating request and response objects in Postman.

● Implemented Kafka consumers and producers to migrate batch processes to real-time streaming, reducing data latency by 45%.

● Automated deployment pipelines with Jenkins on Kubernetes environment and AWS EKS, increasing deployment frequency by 30%.

● Designed and implemented Datadog dashboards to monitor production applications, reducing incident resolution time by 20%.

● Developed high-performance Java batch jobs for processing millions of log files daily, optimizing server resources by 25%.

● Triaged and resolved critical production bugs, ensuring platform uptime of over 99.5%.

● Scripted Python utilities to automate repetitive tasks, saving 5 hours/week in development time.

● Experience in NoSQL database MongoDB scripts in performing DML operations, transactions, indexes and schema design.

● Deployed serverless applications using AWS Lambda to handle asynchronous data processing, reducing operational costs. Java Developer in Silicon Matrix, India Sep 2020 – Nov 2021

● Worked on the migration of legacy Java applications to Java 11, utilizing features like streams and reactive programming to modernize the codebase.

● Leveraged various web technologies including HTML5, CSS3, Bootstrap, MUI, JavaScript (ES6), TypeScript, Redux, Node.js, Express.js, and AWS to develop responsive web applications.

● Developed and integrated an optimized Angular service for data retrieval, leveraging HTTP caching and batch requests techniques, reducing overall application latency by 5%.

● Developed a Middleware Microservice which queries data from Splunk API, rendering it onto a Single Page Application built on Angular.

● Established comprehensive code review practices and design documentation standards, improving code quality and maintainability.

● Actively participated in agile ceremonies, fostering collaboration, and driving project success.

● Utilized Java features like streams, reactive asynchronous programming, AOP, object-oriented programming principles, and design patterns.

● Spearheaded the implementation of CI/CD pipelines with Jenkins, integrating automated testing and deployment, resulting in faster release cycles.

● Built and deployed microservices using Spring Boot to enhance modularity and scalability of applications.

● Designed and implemented relational database schemas using MySQL Server to optimize query performance. Associate Software Engineer in AiRobosoft, India Feb 2020 – Aug 2020

● Implemented Actuator in Spring Boot for monitoring and tracing applications, improving observability across distributed microservices.

● Developed REST APIs, controller classes, and complex services, integrating backend processes using Java and Spring Boot.

● Created JUnit test cases for components, automating continuous integration and deployment using Jenkins, and contributed to the design of a RESTful service interface leveraging Spring MVC.

● Experience in developing, deploying, and testing applications in an AWS environment using DevOps tools such as Jenkins and Docker.

● Database development includes PL/SQL stored procedures, views, indexes, triggers, and constraints to reduce the response time in applications.

● Developed event-driven microservices using Kafka to enable real-time streaming, reducing data latency by 45%. TECHNICAL SKILLS
