Engineering Blueprints

The architectures behind production-ready systems: how I design databases, deploy to AWS, ship through CI/CD, monitor live services and build RAG for AI features. See them applied in my case studies.

Blueprint
PostgreSQL Database Design for SaaS
Multi-tenant schema, constraints, indexing and query tuning for a commerce SaaS, with Redis caching for hot reads.
PostgreSQLRedisSchema design
Blueprint
AWS Deployment Architecture for FastAPI
Containerized FastAPI services on AWS behind a load balancer, with RDS PostgreSQL, ElastiCache Redis, S3 and CloudWatch.
AWSDockerFastAPI
Blueprint
CI/CD Pipeline for Python Backends
Every push linted, type-checked and tested; Docker images built once, deployed to staging, smoke-tested and released with rollback.
CI/CDDockerTesting
Blueprint
Monitoring and Observability for Production APIs
Prometheus metrics, dashboards, SLO-based alerts and structured logs that show how an API behaves in production.

Blueprint
RAG Architecture for Company Knowledge
Retrieval-augmented generation: documents chunked into embeddings, stored for vector search and used to ground LLM answers with sources.
