I’m a Solution Architect and Backend Developer with 8+ years of experience designing and delivering large-scale, reliable systems. I specialize in cloud-native architectures on AWS and implement production-grade microservices in Java, Go, and Python. My focus is on pragmatic architecture, observability, automation, and performance.

I lead end-to-end solutions—system design, service implementation, CI/CD, infra-as-code, and production support—while mentoring teams and aligning engineering trade-offs with business goals.

• Languages: Java (Spring Boot), Go, Python (FastAPI / Flask)
• Cloud: AWS (EKS, ECS, Lambda, API Gateway, SQS/SNS, RDS, DynamoDB, Kinesis)
• Infra & CI/CD: Terraform, CloudFormation, Docker, Kubernetes (EKS), GitHub Actions
• Messaging/Streaming: Kafka, Kinesis, SQS
• Data & Cache: PostgreSQL, Redis, DynamoDB, S3
• Observability & Security: Prometheus, Grafana, ELK, Jaeger, IAM, OWASP
• Testing & Quality: unit/integration, contract testing, performance testing

• Architected a multi-region microservices platform on AWS (Spring Boot + EKS) — improved availability to 99.99% and reduced MTTR by 45%.
• Built event-driven order processing with Kafka & DynamoDB Streams — achieved 20k events/sec throughput and 60% lower latency.
• Migrated monolith to microservices (Java → Go + Java), introduced API Gateway, Canary deploys, and IaC — deployment time cut from hours to minutes and cloud spend reduced by ~30%.
• Implemented Terraform modules for repeatable infra across org environments and enforced security best practices with automated scans.

• High-throughput stream processor — Go · Kafka · DynamoDB — exactly-once processing, autoscaling
  • Repo: github.com/saiprateek/stream-processor
• Modular payment microservice — Java Spring Boot — PCI-aware design, contract tests, canary deployments
  • Repo: github.com/saiprateek/payment-service
• Serverless ingestion pipeline — Python Lambda + API Gateway + SQS — cost-efficient, resilient ingestion
  • Repo: github.com/saiprateek/serverless-ingest
• Terraform org modules — reusable modules for VPC, IAM, EKS, and monitoring
  • Repo: github.com/saiprateek/terraform-modules

• AWS Certified Solutions Architect — Associate Training
• AWS Certified DevOps / Developer

• API-first design, contract tests for cross-team integration
• Event-driven architecture and idempotent processing
• Infrastructure-as-code, automated pipelines, and observability-first deployments
• Mentor devs on architecture, SRE practices, and design reviews

I’m open to architecture reviews, advisory work, and backend/platform engineering roles.
