Cloud, Infra &
CI/CD

See More

Infrastructure & Delivery

AWS, Docker, Jenkins, Nginx, Certbot

  • Migrated binary file storage from PostgreSQL to AWS S3, shrinking database size by ~60%.

  • Containerized all backend services with Docker and built Jenkins CI/CD pipelines.

  • Deployed all services on EC2 behind Nginx with SSL via Certbot and custom domain routing.

  • Managed secrets through AWS Secrets Manager and supported reliable production deployments.

  • Worked across cloud delivery, CI/CD automation, and operational optimization instead of treating infra as an afterthought.

Projects

Featured Work

All API Data Cloud

FastAPI Microservice - Real-Time Analytics

How I Build

Engineering Focus

Secure API Design

I design backend services with JWT auth, OAuth 2.0, RBAC, rate limiting, clean validation, and explicit error contracts so APIs remain secure and easy to consume.

  • Flask and FastAPI service design
  • Token lifecycle and permission control
  • Swagger/OpenAPI-ready endpoints

Data Pipelines That Operate Cleanly

I build ETL and ELT systems that support incremental sync, backfills, alerting, and analytics warehouse delivery without constant manual intervention.

  • Airflow DAG orchestration and scheduling
  • Athena, Redshift, and PostgreSQL movement
  • SNS alerts and observable pipeline states

Cloud Delivery With Operational Discipline

I treat deployment and infrastructure as part of the product, using Docker, Jenkins, Nginx, SSL, and AWS services to ship backend systems with reliability in mind.

  • EC2 deployment, HTTPS, and routing
  • Containerized services and CI/CD pipelines
  • Secrets handling and production readiness
