I worked on async-first backend services using FastAPI with async/await to remove I/O bottlenecks in integration-heavy workflows. I delivered enterprise Django platforms with ORM, authentication, middleware, and admin features to accelerate complex workflows while maintaining stable releases. I standardized Python coding practices (3.12+, type hints, clean OOP) across services to reduce complexity and improve maintainability. I designed clean API contracts with REST versioning, pagination, and idempotency, and introduced GraphQL for data-heavy screens to improve UI responsiveness. I implemented JWT/OAuth2 with RBAC for least-privilege access, built responsive frontends with React/TypeScript, and established caching with Redis to reduce load. I automated deployments via Docker/Kubernetes on AWS/Azure/GCP and implemented observability and testing to improve reliability.

Delivered mission-critical airline digital services for high-volume operational workflows with 99.9%+ availability. Hardened REST APIs with versioning, pagination, validation, and standardized error contracts; introduced GraphQL to reduce over-fetching and improve UI responsiveness. Built cloud-first workloads on AWS (Lambda, API Gateway, DynamoDB/RDS, ECS/EC2) and orchestrated resilient workflows with Step Functions. Implemented event-driven messaging with Kafka/JMS/MQ, adding idempotency and correlation IDs to reduce duplicate processing by 80%+. Strengthened production observability with CloudWatch dashboards/structured logging, lowering MTTR by 20–35%. Enforced least-privilege access via Cognito/IAM and optimized global delivery with CloudFront/Route 53.

Designed and developed backend banking services in Python (FastAPI, Flask, Django) to support digital banking apps and real-time processing. Built REST APIs for payments, accounts, and transactions; implemented asynchronous processing to handle high-volume workloads. Strengthened security with OAuth2, JWT, MFA; integrated Kafka-based messaging and microservices. Modernized legacy workflows, added Redis caching, and tuned queries across Oracle, PostgreSQL, MySQL, and MongoDB. Automated AWS deployments with Lambda/Step Functions; containerized with Docker/Kubernetes; built CI/CD pipelines with Jenkins and GitHub Actions. Contributed to data processing using Spark for analytics and reporting; collaborated with cross-functional teams to deliver scalable backend services.
