B.Tech. in Computer Science & Engineering (CSE) Lovely Professional University, Punjab | 2017About me
Backend-focused Software Engineer with 6+ years of experience building scalable APIs and microservices using Python, FastAPI, Django, PostgreSQL, Kafka, Docker, AWS, and Kubernetes. Strong in system design, debugging, and production-ready solutions.
Python (Programming Language)
Python & Backend Frameworks
Extensive expertise in Python-based backend development using FastAPI, Django, and Flask to build scalable microservices, REST APIs, and data-intensive backend platforms across fintech, cybersecurity, and enterprise applications.
AWS Cloud Services
Strong command of AWS services including AWS Cognito, AWS Lambda, AWS API Gateway, AWS S3, AWS SQS, and AWS CloudWatch for building secure, scalable, and serverless cloud-native architectures.
Microservices & Distributed Systems
Deep experience designing and implementing microservices and distributed systems using Kafka, Docker, gRPC, and asynchronous processing pipelines to ensure high availability and fault tolerance.
Database Management
Proficiency in working with relational and NoSQL databases including PostgreSQL, DynamoDB, Cassandra, Redis, and Neo4j for efficient data storage, querying, and indexing.
Authentication & Security
Hands-on experience implementing multi-factor authentication (MFA), LDAP-based user synchronization, RBAC-based access control, and identity management workflows using AWS Cognito and TeleSign.
Asynchronous Processing
Skilled in building asynchronous processing pipelines using Celery, Kafka, and Asyncio to improve throughput and handle high-volume data ingestion during peak traffic periods.
OCR & Document Processing
Experience developing document-processing workflows using OCR services to extract and process data from multi-page PDFs, reducing manual verification efforts.
Elasticsearch & Search Optimization
Knowledge of Elasticsearch for optimizing search and filtering performance through advanced queries and database indexing techniques in large-scale ticketing and data systems.
Data Migration & ETL
Experience developing data migration and ingestion workflows for large datasets using Pandas and PostgreSQL, including rollback and retry handling for reliable bulk operations.

Project history
90-day internship. Engineered data validation logic for the Incentive Performance Management System (IPMS) to ensure 100% accuracy in financial incentive calculations. Streamlined API reliability by identifying and resolving critical bugs during the testing and debugging phase of the IPMS pilot.
Worked on Alight Worklife (Employee Experience Platform). Implemented sliding-window rate limiting for phone number update APIs, integrated MFA using TeleSign and AWS Cognito, built backend APIs using FastAPI and DynamoDB for secure identity and profile management, and collaborated with cross-functional teams to improve authentication reliability and user onboarding flows. Technologies: Python, FastAPI, AWS Cognito, DynamoDB, TeleSign.
Worked on Pharma Datasphere (Pharma Marketplace). Developed backend services for communication workflows, created reusable AWS Lambda layers for authentication and logging, built and maintained REST APIs using FastAPI and AWS API Gateway, and improved maintainability by reducing duplicated authentication and logging logic across microservices. Technologies: Python, FastAPI, AWS Lambda, AWS Cognito, AWS API Gateway, PostgreSQL, Docker.
